The fossil fuel industry has had no better friend over the past 50 years than the "green" movement. It has worked so well to keep the dirtiest most polluting coal power generation viable that they could not have paid to get better lobbyists.
Following the money and principle of least surprise, you might even be forgiven to think it's very likely anti nuclear movement was funded if not founded by big coal.

"In 1970, a leader of the petroleum industry and the head of the Atlantic Richfield Co. named Robert O. Anderson contributed $200,000 to fund Friends of the Earth, an organization that is strident in its opposition to nuclear energy, citing both safety and cost issues."
Why am I surprised at learning this?

I am actually surprised that the article doesn't provide more examples. The article argues that the fossil fuel industry is paying the antinuclear movement and the single, one example given is a onetime payment in the 70s to start a new organization by a private person. Sure, everyone requires different levels of evidence, but I heavily doubt that you will be able to convince anyone with that one. And then the rest of the text is about how renewable are (as of 2016) so much smaller than the loss in nuclear power.
Well they did the same with "climate scepticism" too, so it's from the playbook.
Another fun one: Greenpeace is a natural gas energy provider in germany (proWindGas)
Yeah of course they are, I was being a bit sarcastic (but also don't know how people here would cope with such "conspiracy theories").
This is not the only area of alignment. The green movement has been pushing for "recycling" of plastics for the last decades. This is a big gift to the oil industry, that has been able to rely on a grassroots movement to put the burden of getting rid of plastic garbage on individuals through "recycling".
Agreed. In "The New Climate War" climate scientist Michael Mann charts the history of polluters convincing the green movement that it should be the responsibility of ordinary citizens to change their behavior rather than polluters. He opens with the "crying Indian" campaign in the 70s--sponsored by the soda industry--to convince people to throw away their bottles in order to avoid legislation that would curb their own profits. Nowadays, "environmentalists" try to persuade people toward veganism and away from SUVs as though these things are (1) ever going to happen en masse or (2) put us anywhere near the necessary ballpark even if (1) happens.
Veganism is funny. Some vegan food, such as avocados and certain nuts (cuisine definition; not botanical) such as almonds require a lot of water to grow, and also there's the transport problem. Although that one's a paradox: a transport ship might seem like its terrible for the environment, but its actually quite efficient compared to an airplane or every customer using their car to drive to the grocery store (though via local consumption it can be avoided). In this respect, individual responsibility matters, you can make a difference in various ways. Don't use fast shipping by airplane even if you can easily afford (only do it by exception), you can also sometimes pick train (e.g. from China, via Russia to Europe). You can do grocery shopping perhaps by bicycle instead of car. Other non-vegan food, where no animal got farmed (a free range chicken a family holds) is thrown away or not eaten (even though it was already produced), foods with trace elements (e.g. milk sugar) is avoided, foods with by-products such as gelatin or whey is avoided. But they drive in a train powered indirectly by coals (electricity network), or use a bus with tires made from pigs. And that's somehow fine (as long as they don't know it). What it boils down to is impact of choice, and simplicity of implementing it. Avoiding eating meat is a lot easier than avoiding any animal (by)products, therefore I find veganism self-defeating, and a luxury (first world) problem as well. No normal, average human being is going to have time to care enough about this issue to put the effort in it, its unreasonable. What works? Taxation, for example. If I'd drive a SUV instead of something small like a Ford Ka or Nissan Kia then I'd be paying a lot more per km on fuel, and for what gain? Its not worth it for me. But Americans barely pay any tax on their fuel.
Why would you say something so controversial, and yet, so true?
> I'll repeat this until I'm blue in the face, has been responsible for smallest number of deaths of any form of energy generation and produce the lowest amount of CO2 (i.e. zero, other than construction).
Will you stop repeating this if I explain why it's false?
So first up, the stat is usually fatalities per TwH, since that skews things in Nuclear's direction, not just number of fatalities which would be won by some obscure but not very successful power source.
Second, even with the correct metric, solar and wind are now beating nuclear and projected to continue to do so, widening the gap over time. Comparing the very start of the renewable rollout gives misleading stats as the total power generated is low, and many stats that get quoted on this are more than a decade out of date.
You can build a wind turbine and ritually sacrifice someone on completion of the build and the fatalities per TwH is infinite as it's not generated any power yet, but with every year of operation it gets lower.
Basically the same applies to carbon output, nuclear does well, but wind/solar/nuclear have been basically tied on both metrics unless you're relying on some very, very old data.
Of course if you have a limited amount of money to spend, then you'll generate more energy and save more lives with whatever the cheaper form of energy is, so we should really take that into consideration too.

But it doesn't matter anyway - wind and solar should complement to nuclear, not to replace it.
This year we saw weaker summer winds in Europe which is part of what has caused the current energy crisis. These weaker winds are expected to become more common as climate change continues.[1]
Nuclear has the benefit that it's reliable. If you design a plant to output X gigawatts - it'll still be able to do so regardless of the weather.

No, nuclear plants are regularly taken offline for weather related reasons.
The main problem seems to be that people have invented an entirely ficticious nuclear power that does not and has never existed, just so they can slag off renewables and "elite culture" whatever the heck that is.
The real actual nuclear power, which is better than coal, but not particularly competitive with modern renewables is apparently irrelevant to people who have bizarrely joined a one sided culture war on the side of fossil fuel companies and think this makes them cool, well informed and counter-cultural despite reality leaning the other way.

Probably because Ontario has ample access to water cooling, probably from the lakes. That's not the case for many countries in Europe.
No doubt. But it's important to differentiate "inherit" limitations of a technology versus situational ones.
Plenty of EU countries have coast lines too.
Plenty of EU countries have coast lines too.
Yeah, and they have floods, too (Re: Fukushima). I'm a proponent of nuclear fission energy (to complement solar/wind/hydro) but it has to be done safely. Hopefully in the future we don't have to rely on it (switch to nuclear fusion or something else), or solve the nuclear waste issue somehow.
Green energy and nuclear are in different product categories. They are in no way comparable. It's like trying to compare an electric scooter to a work truck. This is because green energy is mostly fine for transient demand, but at this time, is completely unsuitable for base load applications. Nuclear is a base load product (base load pricing is quite expensive) and needs to be far more reliable. Its failure modes are such that we can build a reliable energy grid around it, and have done for decades. You can't say the same for green energy (right now) as evidenced by its multiple failures as of late, which is now responsible for decreasing the security of Europe.
In 2021 there are only two useful types of power: cheap power and peak power, and nuclear is neither.
Base power is only a useful term if it's cheaper than peak power, since you can fill 100% of your power needs solely with peak power.
Base power is only a useful term if it's cheaper than peak power, since you can fill 100% of your power needs solely with peak power.
The crisis in Europe and elsewhere shoots holes in the theory that baseload is somehow no longer applicable. Baseload is not cheap particularly because it must be very reliable (and is more expensive), and is why green energy alone is too variable and completely insufficient at present to replace other baseload providers.
Peak power has to be reliable or you get brownouts.
Baseline power can be unreliable because peak power will cover the unreliability.
Baseline power can be unreliable because peak power will cover the unreliability.
The assumption embedded in that line of thought is that the failure modes (and times) of peak and baseline power will never significantly overlap. Essentially, by injecting more variance and different types of uncertainty, frailty and the chance of systemic failure are increased (as shown in Europe), especially regarding second and third order effects.
How about something like an SLA for power?
Clearly, placing any country's energy security in the hands of ever changing climate (less winds and high cloud cover) or at the feet of dictators has to factor in some where.
Clearly, placing any country's energy security in the hands of ever changing climate (less winds and high cloud cover) or at the feet of dictators has to factor in some where.
There are a number of issues:
1) Short term, the faster we avoid CO2 the better. If SLAs make that more complex, then it is a net loss. Long term, the situation will be different because cheap gains will be gone.
2) Europe has mostly privatized energy. Who is suppose to set the SLA?
3) Nuclear plants need to be refueled. Does the SLA include a couple of months downtime every few years? That would suggest that the SLA is uniquely tailored to nuclear. 100% uptime? How is nuclear going to deal with that?
4) Power consumption varies over the day. A constant load again favors nuclear. A load that can handle daily and seasonal variation would be quite bad for nuclear.
Basically what we need is flexible electricity production. On their own, nuclear, solar and wind are all equally bad at flexible electricity production. So the questions are: - how do we get cheap storage - how do we minimize the amount of storage we need

The minimum requirements for the manoeuvrability capabilities of modern reactors are defined by the utilities requirements that are based on the requirements of the grid operators. For example, according to the current version of the European Utilities Requirements (EUR) the NPP must at least be capable of daily load cycling operation between 50% and 100 % of its rated power Pr, with a rate of change of electric output of 3-5% of Pr per minute
Most of the modern designs implement even higher manoeuvrability capabilities, with the possibility of planned and unplanned load-following in a wide power range and with ramps of 5% Pr per minute

Technically that is true. Economically, that means that if a nuclear power plant runs for significant amount of time at 50%, the price of electricity will almost double.
> No, nuclear plants are regularly taken offline for weather related reasons.
Do you have a source for this?
Do you have a source for this?
Nuclear plants use water from a local river, or sea, for cooling. Or some plants use air and have cooling towers. Nuclear plants are also tightly regulated by law. So there is a limit on how warm cooling water the plant is allowed, as per environmental regulations, to release into the river, or to the sea.
If weather gets hot, the temperature of the incoming cooling water gets warmer, too. And having to operate within the limits of the maximum allowed temperature for the outgoing cooling water, the plant may have to regulate its power output, or maybe entirely pause operation.
The temperature limit is mostly a legal one: There is concern about the environmental effects of releasing warmer water to the water bodies. From an engineering point of view, the plant would probably be able to operate, and just release warmer water.

I'm not debating the mechanisms; I'm after a source that hopefully reliably cites the frequency and severity of it. Wind and solar power drop to zero regularly, as we would expect. If nuclear does the same, then the comparison is totally valid. If it's something else then the comparison becomes less valid or invalid.
Why are you so keen to defend one particular power production method on one narrow stat?
This isn't a game of Top Trumps where you need to find any one stat that's higher than your opponents to declare victory.
Nuclear has to be better than wind and solar and hydro and batteries and everything else (demand response, better insulation, undersea grid connectors etc.) all working together across a wide range of metrics to find a place in a modern grid.
It is failing at this. The alternatives are cheaper, better, greener, safer, quicker to build.
Narrowly focusing on one tiny aspect does not change this big picture reality.

I'm not keen to defend anything. I know this can seem unusual, but I'm just trying to understand the situation as well as possible. I'm not treating any option as a team to blindly cheer on.
The problem with what you're saying is that to supply peak power at all times could require building capacity in each method to supply full power, in case the others all fall to zero power. And even then, you hope that they don't all fall to zero, I guess.

Why can't they just refrigerate the water before releasing? Nothing too crazy just a few degrees. Run it through cooling pipes are something to dissipate the heat.
They could evaporate some of the water to cool the rest. This is why many nuclear plants in the US have cooling towers. But cooling towers consume water, and are fairly expensive.
I found this article : https://energyforhumanity.org/en/resources/reports-en/effect...
Curtailment of nuclear power due to periods of extreme heat has had the effect of reducing European nuclear power output by approx. 0.1% since the year 2000. For France specifically, which with its many inland river-sited plants has been the worst hit country, the corresponding figure is approximately 0.15%

Thanks. This doesn't sound appropriate to compare with how weather affects most renewables.
Every summer in France
That sounds good, predictability is what you want when designing a power grid.
Source? Is this inherent in all nuclear plants, or only in certain designs?
It happens all the time;

> Now, increasingly, more frequent heat waves and hotter average temperatures are making those waters so warm that engineers are concerned that it can't do the job. Analysts say climate change is to blame.
> In little-noticed but publicly available reports to regulators, nuclear plant owners revealed that unusually hot temperatures last year forced them to reduce the plants' electricity output more than 30 times – most often in the summer, when demand from nuclear plants is at its highest. In 2012, such incidents occurred at least 60 times. At one plant in Connecticut a reactor was taken offline for nearly two weeks when temperatures in the Long Island Sound surged past 75 degrees.
It's not like you can just change the legislation to say "allow hotter discharge water" though -- the plants' very engineering criteria is being impacted. Warmer water has lower absorptive capacity to cool the primary loop so things get dicey when temps increase outside the design specification.

All designs that take water from rivers and return it there. There usually is a regulation for the maximum water temperature in the rivers, so during the summer they can't heat up the water as much, leading to lowered energy output to the point where they have to shutdown some or all reactors of a plant.
That doesn’t imply that nuclear plants regularly get close to this threshold nor that it’s common for all nuclear plants of this type (consider 2 identical plants positioned on differently-sized rivers: the larger river will be able to absorb more heat than the smaller river, ergo reliability of this sort varies).
It's not just the river's ability to absorb the heat, it's also the plant's design criteria. The river water is the coolant in the secondary loop, warm water obviously has less capacity to absorb heat, so the plant will either get hotter (not great!) or will have to slow down the reaction to produce less heat (also not great during the summer when demand is the highest!). This isn't just an environmental concern but a design problem.

In my country (Ukraine), 3 nuclear power plants out of 15 are competing with cities for fresh water because of drought.
I like the engineering of nuclear power plants, but I'm not particularly biased towards them over renewables.
But we need to greatly improve energy storage if renewables are going to work.
Places like Scotland have generated equivalent to around 97% of their entire electricity consumption from renewables - yet still consume around 13% of their energy from fossil fuels as they export the renewable energy at peak production.[1]
I also just really don't like the misinformation that surrounds nuclear energy. I majored in Physics and it's just irritating to see people so confident in their ignorance. I recommend the book "Atomic Accidents"[2] as an excellent book on the dangers of nuclear power and nuclear power plant engineering in general.

Yeah. We need a better transmission grid before we can go to 100% renewables (balancing out Scottish wind with Spanish solar). But a better transmission grid is miles cheaper than nuclear, so it's still a no brainer.
Citation? In particular, small modular reactors are estimated to produce energy at a cost which rivals natural gas (but we can’t know for sure because anti-nuclear folks have prevented us from seriously testing it) which is almost certainly less than the cost of solar/wind and tens of thousands of km of massive copper cables.
> small modular reactors are estimated to produce energy at a cost which rivals natural gas
You'd be foolish to believe those projections from salesmen. NuScale's attempt at new reactors has already doubled in cost.
You'd be foolish to believe those projections from salesmen. NuScale's attempt at new reactors has already doubled in cost.
So let’s get our thumb off the scales and allow them to build their technology so we can find out it’s true price? It’s equally foolish to assume that the prices won’t fall over time as we optimize.
What do you mean by "thumb off the scales"? Elimination of nuclear regulation? I'm sure that would be politically sane. /s
If you were here in good faith, you would know that regulation isn't an all-or-nothing proposition.
I guess we just need omniscient philosopher-kings to tell us ahead of times which safety regulations were actually necessary. Is there R&D into crystal balls?
So we have high operational costs but a lower capital cost for SMRs since we lose the size advantage of regular reactors. We then hope that these higher operational costs are offset due to the scale advantages of building many reactors. That's gonna require some huge cost savings?
You're making a lot of assumptions, including that the only difference between SMRs and older generation reactors is size. SMRs are also much simpler, with the express purpose of reducing operational costs. Maybe the operational costs would be higher, but we aren't going to know that without more robust analysis or--heaven forbid--trying out SMRs.
They will be a bigger part of the costs compared to current reactors. Which is normal because employment costs are high. It's a popular choice now because all the latest reactors in the west have huge budget overruns.
This is for America, I don't have anything to hand for Europe
https://www.greentechmedia.com/articles/read/study-transmiss...
Also, this is with technology we have right now that we know works. The problem with SMRs is they have always been 5-10 years away from being ready. We have to plan based on what we know now, not make pipe dreams based on technology we would like to have and which may never pan out.

The us navy has been building SMRs for decades. Their reactors don't need to generally be refueled either since they use higher grade fuels and burn them in place for 30+ years. So, there are differences but mostly these aren't cutting edge designs, they are 50 year old concepts that have been studied and understood to death.
Yes there are differences, but the fact that the NRC can't certify a reactor class that the navy builds (without interference from the NRC) is itself a problem.

I have a hard time seeing nuclear weapons grade fissile materials spread around in every SMR in every town around the world as a feasible solution.

Same deal with solving for reliability with renewables. We should invest in solving both problems. Moreover, I suspect that "always 5-10 years away from being ready" has a lot more to do with regulators than feasibility.

Exactly, the price of nukes are roughly 100% regulation at this point. nuscale spent $500M+ just pushing paperwork at the NRC in the US and still haven't built one. It wouldn't surprise me if the NRC required global asteroid strike mitigations, just in case. The fact that not a single NRC approved design has successfully been built, should tell you that they exist to drive the costs so high has to be economically unfeasible.
Apparently, South Korea though has kept the costs down to 1980's levels.
A buddy of mine's joke is that the cheapest way to get new nuke plants in the US is to build a huge naval fleet and park them in ports.

Plus, you lose lots in transmission over such distances.
I might note for readers of you book recommendation that despite the title, James A. Mahaffey the author also wrote a pro nuclear book and was a contributor to Power to Save the World[1].

If we're choosing power sources based on the amount of lies told about them, then I'm afraid renewables win on that metric as well.
They invented a conspiracy theory that the entire planet's scientific community was trying to destroy the economy for secret marxism reasons for goodness sake.
You'd need to find someone who thinks Godzilla is a documentary to equal that level of nonsense.

No one is making those arguments here so why bring them up? Unlike nuclear, that misinformation isn’t suppressing investment.
Because the person he was responding to was using anti-nuclear bad arguments as a reason for using nuclear. Sauce for the goose, sauce for the gander.
Misinformation isn't suppressing nuclear investment, the all too real cost of nuclear is.
Misinformation isn't suppressing nuclear investment, the all too real cost of nuclear is.
I repeat: bad arguments aren’t a problem for renewables as with nuclear.
I reject your claim that bad arguments are hurting nuclear. Nuclear is in trouble because of devastating correct economic arguments.
Nonsense. If it weren't for FUD campaigns, nuclear energy regulations could be more lax (there's a huge chasm between the safety of nuclear and fossil fuels and no one had a problem with fossil fuel deaths for most of the last half century) and investment could continue in finding more economical designs. Note that various Asian countries are able to build and operate even older nuclear plants economically.
Nonsense right back at you. Nuclear with a normal level of regulation, with the same level of up-fuckery seen in other industries, would have eventually reached a level of safety, but only after a long string of nuclear accidents (just like as air transport required large numbers of crashes to achieve today's safety.)
Would that have been politically realistic? I think clearly it wouldn't have been. So don't complain about a level of regulation that nuclear requires in order to exist at all.

> The real actual nuclear power, which is better than coal, but not particularly competitive with modern renewables
“Modern renewables” aren’t competitive at all, you can’t build a grid based on them. The ginormous amount of renewables in Germany compared to how much CO2 per kWh their grid produces (https://app.electricitymap.org/zone/DE ) is everything you need to know.
Even in places like California (where I live) where Solar is viable, renewables will require so many battery storage to remove gas plants that it’ll push their co2/kWh way higher that nuclear.

You have invented a fictitious enemy in your own made up "culture war" to rage and rail against what you believe is the one true answer. Thousands of hectares of pristine remnant bush are bulldozed to move, note not install, move, wind turbines into place. Nobody blinks an eye when thousands of hectares of remnant bush gets covered in solar panels. I'm the greenest person I know, a self identifying eco-facist. And I want a nuclear power station in every suburb. And so should you, if you gave a rats arse about the actual environment, and not some fake "war" raging in your meme-space while actual living things get ground into dust in the actual real world.
That sounds really deranged.
> No, nuclear plants are regularly taken offline for weather related reasons.
Could you please expand on this? What is the ideal uptime for a nuclear plant vs wind/solar?

They don't. They explicitly compete for the same spot, the cheapest most inflexible power generation. Nuclear obviously loses here and are pushed closer to the peaker side and is hampered by the insanely costly initial investment. The closer to peaker you are the more you want the price to only be operating costs.
dunno why this got down voted. Nuclear is a terrible peaker tech and yet pairing it with solar/wind requires it to be flexible and so you end up overproducing.
There isn't a perfect scalable peaker / clean generation tech unfortunately but storage does the trick instead.

Agree completely.
It seems very naive on the one hand to say that climate change is making climate more chaotic and and then turn around and say that we will put all our eggs in the baskets of tech that literally doesn’t work if there isn’t suitable climate (wind and solar).

> Nuclear has the benefit that it's reliable. If you design a plant to output X gigawatts - it'll still be able to do so regardless of the weather.
Unless, of course, the weather is an earthquake followed by tsunami.
Or political weather.

Although a bunch of solar panels or wind turbines on the coast that are washed away by a tsunami isn't reliable either. Or when there's no wind or sun.
If it takes a tsunami to turn off a nuclear plant, it's about as reliable as it can be.

"Do everything" is wrong. This is why: You want the most power per dollar of capex, and you want to have it come on line as fast as possible. Electricity is fungible. You can't tell a coal watt from a solar watt from a nuke watt. If you want to avoid coal, oil, and gas for externalities, you want the thing that costs the least and arrives soonest. That's renewables.
Every dollar spend on nuclear would deliver more power sooner if spent on renewables.
Every dollar spend on nuclear would deliver more power sooner if spent on renewables.
Except you can't just invest it all into renewables and expect to have a stable power grid, the equation isn't quite as simple as "avg_power / $ capex".
Last analysis I saw of this argued that the amount of "over-provisioning" needed to cover baseline demand with renewables made them prohibitively expensive as the sole solution. Peaker and storage solutions aim to solve that, but you need to build that capacity in addition to renewables.
Here's a fully costed plan to green the grid.
It only requires over-provisioning of 20%. https://mitpress.mit.edu/books/electrify
Here's an anti-renewable paper that quite ironically makes the point quite well that battery storage is quite viable: https://www.nature.com/articles/s41467-021-26355-z
Take a look at the graphs at the back. It shows a 99.99% reliable grid made up of an optimal mix of solar & wind, 3x over-provisioned along with 3 hours of storage and a continental grid.
We don't need 3x over-provisioning because the paper doesn't include hydro or existing nuclear. And 3 hours of storage is a lot of batteries, but it's a lot cheaper than building new nuclear.

Renewables are nowhere near to running up against the need to buy more grid interconnection, storage, synfuel technology, or other ways of using surplus power and providing power from storage or from other regions.
Until renewables displace a lot more fossil fuel power, those costs are not a consideration. That might happen within a decade in places like New Zealand.
Still, capex on grid scale storage is up and costs are trending down: https://www.renewableenergyworld.com/storage/investment-tren...

The main power grid should be always from a predictable source. wind and solar are far from that. And there's the problem of disposing solar panels and old wind turbines. We came a long way, but there's a lot of space for improvements. Meanwhile, nuclear energy is a stable and mature technology.
There is no need for a base load source to supply a base load of demand. Intermittent sources + storage to fill in the gaps can work just fine. The new thing is that this latter approach is looking like it will be cheaper.
Im no expert on batteries, but I don't see giant watery banks working in large scale, in most cities in the world. Today the better way to store energy still is with water reservoirs, and its expensive as hell, and you need a gigantic space that will be flooded.
That’s a LOT of batteries…
The world is going to spend maybe a quadrillion dollars on energy over the next century. Big problems have big solutions.
Why build a bajillion batteries with all sorts of hazardous chems if we can do nuclear that has small amounts of waste.
Let’s say you can fit the waste from a certain amount of nuclear energy in a barrel. How much energy can you create with the other methods, given you can only fill up that same barrel?
With battery-supported renewables, my guess is: a hell of a lot less.

Physics couldn't care less about your "big solutions".
All energy storage solutions we have are low capacity, slow to charge, slow to bring online, and often are extremely harmful to the environment to produce.
Of course, you can close your eyes, and pretend this will be solved by magic in the nearest future. It won't. And we need solutions now.

The implication that physics prevents renewables and storage from being able to do the job is a despicable lie.
The physical attributes of existing batteries (and related energy storage technologies, like hydrogen for long term storage) are perfectly compatible with a 100% renewable grid. We're just haggling over the cost at this point.
I was addressing the shallow objection that it's a "lot of batteries". That's fine; the budget is will allow purchase of a lot of batteries, and all sorts of other stuff too.

So, this was your argument
"All energy storage solutions we have are low capacity, slow to charge, slow to bring online, and often are extremely harmful to the environment to produce."
This is 100% bullshit. Energy storage solutions can be scaled as high as we want. They can charge as fast as is needed. By "slow to bring online" you might mean two things (cannot be switch on to deliver power to the grid from an off state quickly, or cannot be built quickly), both of which are false. As for "extremely harmful to the environment", I also see no reason to believe that is true, especially compared to either the harm of CO2 or the harm imposed by the existence of industrial civilzation at all.
So, you listed reasons, and they appear spurious. Care to defend your claims?

This is very high in emotion but low on content.
Current storage solutions: batteries, water in a dam, molten salt.
Energy density: low
Environmental impact: Dams: need to flood a massive area to make a dent. For example the utterly colossal Three Gorges supplies only 1% of China’s power.
Batteries: filled with extremely bad heavy metals. It’s barely OK right now; if we covered the planet in huge battery farms, it would be a catastrophe.
Molten salt/other temperature-based methods: works with turbine-based generators, not solar/wind.
Responsiveness: low, except for batteries.
Ultimately this whole thing needs less shouting and more spreadsheets.

The sibling comment has already showed all the ways in which you are wrong. So I'll address only this part. " I also see no reason to believe that is true". That's the problem with starry-eyed proponents of anything really: they chose belief over facts.

There also a slow revolution coming in nuclear energy of small, modular reactors, that are easier to maintain, produce less waste and are safer.
well, don't you get more solar power in the summer?
seems like that can minimize seasonal storage requirements once higher level of renewables are in the grid

> You can build a wind turbine and ritually sacrifice someone on completion of the build and the fatalities per TwH is infinite as it's not generated any power yet, but with every year of operation it gets lower.
No, wind towers don't have infinite generation, require maintenance and decommissioning, and have been well around for long enough that statistics are quite well available throughout the lifecycle. People have been acting like we've been at the very start of the renewable rollout for the past 30 years, which is longer than the operating life of an average wind turbine.
> Basically the same applies to carbon output, nuclear does well, but wind/solar/nuclear have been basically tied on both metrics unless you're relying on some very, very old data.
Again I've been hearing that renewable energy will solve all this and nothing else can for the past 20 years if not more. Hundreds of nuclear plants could have been built and running in that time now.
Funny thing is it keeps getting repeated. Again, and again, and again, by people who don't understand the fundamentals. Coal was doomed, completely on the way out and destroyed by wind and even solar just a couple of years ago according to these very same anti nuclear people. Today, thermal coal prices have been at record highs for the past year. Coal production is ramping in many countries and global consumption is near record highs and will take many decades to drop. Coal plants are being built with 40 year lifespans.
Where's wind and solar? Still only make up little more than 10% of global electricity generation. Most of the stats for renewables quoted includes hydro which exceeds both of them combined.

That's not going to solve climate change is it? It's not even reducing existing fossil fuel installations let alone providing all new energy requirements. Like a real nuclear effort could have.
And "capacity" of course means something very different when it comes to the wind and solar, which makes that 2/3 not as great as it sounds.
No, the anti-nuclear luddites and conspiracy theorists have no credibility. They are dangerous climate deniers who should not be listened to. The amount of damage they have already caused may well be incalculable.

They're building 2 nuke plants worth of solar and 1 plant worth of wind in 2022. In a single year. That'd be about $100B if it was nuclear. Given that it takes about 20 years to build a nuke, that means 60 plants being built simultaneously, total cost $2T. That would never happen.
Who is they? And are you talking about the total generating capacity? 3 nuclear plants per year is laughable compared to what needs to be done. It's barely enough to maintain the greenhouse gas footprint let alone reduce it significantly.
And nuclear would never happen thanks to the anti-nuclear / pro-fossil-fuel "green" lobby. I'm not saying it would, I'm saying it's been killed and along with it the climate by these lunatics.
Big coal is happy though, they're making some astounding profits in the past year or two, wind turbines or no wind turbines.

That's exactly my question. In this magical world where nuclear power regulations are similar to coal power regulations, who is going to spend the tens of trillions of dollars necessary to partially solve the climate change crisis with nuclear plant?
The same people who spent money to provide much of France's electricity with nuclear. The ones who built Japanese and American and Russian and Canadian and Chinese nuclear plants.
The rambling anti-nuclear / pro-carbon rhetoric somehow handwaves about how you can't do that and how renewables will magically solve everything. They were wrong 50 years ago, they were wrong 20 years ago, they're wrong now. Nuclear power still provides as much electricity as wind and solar combined. Today.

I've often wondered about those % measurements of electricity generation.
Because of high variability balancing wind/solar is apparently tricky since rarely is storage capacity built along with the wind/solar (I kinda wish that subsidies focused on that).
So... of that 10%, how much of it is excess power that had to be soaked up wherever a place could be found to dump it, and or rapid ramping down of base generation, causing waste. It's probably a hard thing to calculate though.
> No, wind towers don't have infinite generation, require maintenance and decommissioning, and have been well around for long enough that statistics are quite well available throughout the lifecycle.
GP was making the opposite point that 1 (sacrificial death) ÷ 0 (TW generated from a brand new tower) is "infinite" (fatalities per TWh) which would really be undefined, not infinite, but a silly point regardless.

How about:
* stop shutting down current nuclear electrical generation capacity
* build more solar and wind capacity
* as more renewable capacity comes online use it retire fossil fuel generators
Once all the carbon-emitting stuff is offline then perhaps look at shutting down current nuclear.
You know: the opposite of what Germany is doing.

Germany is shutting down coal power plants, not just nuclear. Last year eight lignite fired plants and ten hard coal fired plants were shut down. A total of 7.6 GW, compare that to the 4.3 GW of nuclear that was also shut down last year.

Would they have been able to shutdown coal/gas faster if the nukes were kept running? If the 4.3 GW of nuclear was still around, how many more plants—with their corresponding CO2 emissions—could have been eliminated?
Could Germany reduce its dependency on Russian gas with more nuclear?

> Would they have been able to shutdown coal/gas faster if the nukes were kept running?
Probably, but it's not just the politicians and the population who don't want nuclear power, it's also the operators. They're not interested anymore as they can't plan ahead. If the current government decided that the nuclear power plants should run longer they would all need to get modernised first, meaning the operators would have to invest and who says the next government won't shut down them down again. Nobody is going to invest in building a new nuclear power plant that may or may not enter operation in 15-20 years.
> Could Germany reduce its dependency on Russian gas with more nuclear?
Short answer: No. Germany mostly relies on gas for heating, not for electricity.

No where in my post did I say anything about new plants. Simply keep the current ones going until (a) coal/gas is retired, (b) enough renewables are built to then start retiring current nuclear plants.

Even the old plants would require investment for modernisation.
Winters can get cold depending on the area, but probably warmer on average than Canada. There are currently around 30 million households (around 75%) heating with either gas (50%) or oil (25%). Don't get me wrong, they will all eventually have to switch to some other heating method, most likely to heat pumps, but that will take a few years to maybe a decade.

Why is it false?
I'm talking about absolute numbers here, not TWh, and I'm comparing to fossil fuels, but even if we talk about just wind:
> In England, there were 163 wind turbine accidents that killed 14 people in 2011. Wind produced about 15 billion kWhrs that year, so using a capacity factor of 25%, that translates to about 1,000 deaths per trillion kWhrs produced (the world produces 15 trillion kWhrs per year from all sources).
> These are pretty low numbers. By contrast, in 2011 coal produced about 180 billion kWhrs in England with about 3,000 related deaths. Nuclear energy produced over 90 billion kWhrs in England with no deaths. In that same year, America produced about 800 billion kWhrs from nuclear with no deaths.
https://www.forbes.com/sites/jamesconca/2013/09/29/forget-ea...
I'm sure deaths are going to increase in the production, erection, and servicing of tens of thousands of wind turbines, by tens of thousands of employees.
But you can simply tally up all the deaths for nuclear accidents, direct or indirect, and they're still less than other forms of energy generation.
Presumably you're disputing the deaths, but the link you gave is deaths per TWh is lower. Except by absolute deaths it's.... higher. Which was my point, and is reinforced in the quote above.
> Second, even with the correct metric, solar and wind are now beating nuclear and projected to continue to do so, widening the gap over time.
Yes, deaths per TWh will go down, but power generation will go up, as there is more solar/wind, but so will deaths as more people build, install, and maintain those systems. Those absolute deaths keep rising.

This is true but not very significant since nuclear is still forty times safer than the next safest energy source, natural gas. Solar, nuclear, and wind all have a niche in a green future. Nuclear fits in locations with insufficient wind and solar resources and provides reliable base supply.

Why does nuclear have a niche in a green future? I don't see it surviving. Locations with insufficient wind/solar will be supplied externally, either by grid or by transport of synthetic chemical fuels. Places like very high latitudes (where wind is often very good, btw) are so sparsely populated they cannot by themselves sustain a nuclear industry.

Building cables across the ocean raises much more demanding engineering problems but much less demanding political problems than building them across multiple states. You don't have to please a bunch of different regional governments and land owners when you're building across the ocean. If you have a government that can dictate national projects like in China you can build long cables over land even faster, but that political alternative also comes with its own problems (to put it mildly).
Naa, we use gigantic mirrows in space to bring light to the night side.
in theory SMRs don't need much maintenance so could work in these situations. And on the plus side, when they do melt down - not many casualties.
When the entire Railbelt grid in Alaska (the largest grid there) has an average load of 600 MW, there simply isn't much market for SMRs at high latitudes.

So remote islands basically (places not worth adding to a super grid). Fair enough. That's a very small niche though.

Is there currently any region in the world where wind and solar alone are capable of providing a reliable base supply?
Is that a rhetorical question? It sounds like an oxymoron.
Neither solar nor wind can provide base power. Unless you can make hyperefficient batteries and guarantee that we'll see cloudless skies and constant wind.

yes. plenty. north america, europe, china - to name three examples.
The larger your grid, the more reliably you can source renewables. It's not cheap to install the necessary high frequency inter-connectors but it is still waaaay cheaper than nuclear (see a different thread where i posted a link on an MIT study).
Edit: also, you still need a lot of storage (probably 12-48 hours worth) but i posted another link showing how that's also way cheaper than nuclear.

You only need 3 hours worth of storage. https://www.nature.com/articles/s41467-021-26355-z
Take a look at the graphs at the back. It shows a 99.99% reliable grid made up of an optimal mix of solar & wind, 3x over-provisioned along with 3 hours of storage and a continental grid.

I'm skimming this rightn now, but a quick question: do they take into consideration the space required by wind and solar farms?
Also, three hours of storage for a continental grid? Nice dream.

They don't take space requirements into consideration probably because it's trivial to dismiss. 40,000 square miles would provide enough energy to power the entire US with solar, in a country with 3.6 million of them. That's less than the space taken up by cemeteries.
And continental is what makes 3 hours possible. The wind is always blowing somewhere.

No, it wouldn't. As the document yo link shows, even countries with similar makeup have very different solar and wind profiles.
Also. You can't just wave your magic wand and say: "here, we now have 40k square miles". You're saying "oh, let's just randomly find an area larger than Austria (population: 9 million people + farmland + industry + ...) and cover it entirely in solar panels (without taking into consideration the place for all the required infrastructure to go with them".
It is so, so trivial to dismiss, true.
> The wind is always blowing somewhere.
Only... What is the amount of that wind? Is there enough wind in Denmark to cover non-windy days in Spain? Will the grid be able to switch fast enough? (answer is: no, because renewable sources are notoriously slow to ramp up production)
Ah yes, so trivial.

The power generation capacity in the US is worth trillions. That kind of money is a magic wand that can makes obstacles like 40k square miles pretty trivial.

Comon, if we can't store energy for 3 hours that's an armutszeugnis. The battery of my electric bycicle can store the energy needed to power my flat for 3 hours.

The UK normally gets 25% of their electricity from wind but just the other night they were only getting about 2.7% of the demand fulfilled by wind turbines. They had to start up coal plants to fill the gap.
I don't think over provisioning would fix that and you'd need about 12 hours of batteries to cover the shortage.

I have conflicting data about deaths per TWh
https://www.statista.com/statistics/494425/death-rate-worldw...
Most other sources repeat either numbers.
And it is not surprising, because we are talking about very different things. Solar-related deaths are mostly people falling from rooftops, Hydro-related deaths mostly come from a single event: the Banqiao dam failure, and Nuclear-related deaths depend a lot on how you count Chernobyl and Fukushima. Coal goes through the roof, mostly because of pollution.
We simply don't know how many people die from the Chernobyl disaster, from 31 to hundreds of thousands, yes, it is that fuzzy. I think the most official number is around 4000, but who knows what number they used to make these numbers? It is probably in the fine print somewhere if really look for it.
Mining operations are also taken into account, but how deep shall we go into the supply chain? Do we count the fatalities related to the raw materials that make the plant? What about the guy who dies in a car accident going to work at the power plant?
Do these numbers even make sense or are they just politics? By carefully picking my metrics, I could probably make coal looks very safe and solar very dangerous if I wanted to.

Projected is the operative word.
One useful concept that was introduced a decade ago is a "cubic mile of oil", or CMO. To yield the equivalent power, one would need to produce 250,000 roof-top solar systems a day for 50 years, or 1200 turbines a week for 50 years, or 1 nuclear power plant a week for 50 years. Innovation is still desperately needed here. Nuclear has been unfairly sluggish in this department.

One nuke plant a week for 50 years sounds like a lot, but they aren't really that complex, and 52 a year isn't really that many construction projects worldwide. Your talking 2600 plants.
If every mid sized+ city in the world started building one today, and it took 5 years to construct, and they started a new one every other year (so they were being built in parallel). The problem would be solved within a decade.
A year or so ago, I looked at the cost of South Texas Project in Texas, and how much power it generates and figured out that for roughly a single year's state budget one could build 10x those plants, which would remove all natural gas, and coal electric production in the state. Do it a second time, and there would be enough to actually move a significant part of the cars to electric too.

Total power generated doesn't matter as much as you think it does. Base load and load following matter never factor into the starry-eyed discussions of renewable power sources. Weak winds at night? Boom, suddenly you require other means of producing energy.

You can back that up with combustion turbines. The cost/watt of a simple cycle combustion turbine powerplant is just 5% of the cost/W of a nuclear power plant (combined cycle, just 10%), so backing up the entire grid this way is cheap (in capital cost) compared to the capital cost of a nuclear-powered grid. If you don't use those turbines very often, the fuel cost is manageable, even if you use non-fossil fuels like "green" hydrogen. To cut down on that fuel cost, you can also add some batteries to reduce the fraction of time the turbines are required to operate.
> You can back that up with combustion turbines.
So, back that up with burning natural gas.

So, the "cheap" is in reality:
- many gas powered energy plants (that are not there, and need to be built)
- plus many batteries (that are not there, and need to be built)
- plus cheap natural gas to burn
So much for "green energy already has the capacity to replace something"

Yes, all of those are likely going to be true. Are they true at this instant? Maybe not, but a nuclear plant we start building today also won't be available at this instant.
Note that the application of green hydrogen I'm talking about here, grid backup, does not require replacing existing natural gas use with hydrogen. Nor does it require long distance hydrogen pipelines.

There's no "but". The situation right now is that starry-eyed proponents of renewal energy sources claim that they have already surpassed nuclear etc. When in reality they can't cover the basics. And the answer to that? "Oh, yeah, sometime in the future there may be something to complement this".

I assume you're being sarcastic. Hydrogen can escape through solid metal, making it brittle in the process. It's cheap to produce from natural gas, but that's not green hydrogen. Green hydrogen is a lot more expensive. It's also very voluminous unless liquified which requires a ton of energy and refrigeration to maintain.
> I assume you're being sarcastic.

We aren’t debating obscure energy sources anyway, so I don’t see what the point is. This is absolutely the correct unit.
> solar and wind are now beating nuclear and projected to continue to do so, widening the gap over time
Rooftop solar is still losing, but yes renewables in general are still competitive. If the anti-nuclear lobby would allow nuclear to advance beyond 70s tech we could probably see a lot of advances on the nuclear side as well, especially with smaller mass-produced reactors. It’s pretty crumby to criticize nuclear when you’re putting your thumb on the scales.
Moreover, are these figures measuring the actual production or just the capacity? You need a lot more than 1TW of solar or wind capacity to produce 24TWh of energy in a 24 hour period because these energy sources aren’t reliable. You also need something to store the energy (or transmit excess energy to places that can use it)—the construction of which increases the cost, carbon footprint, and fatality count.
Frankly, all of these sources blow fossil fuels out of the water so I don’t much care which of them we use, but we should have a diverse mix for reliability and we should prioritize what works rather than waiting for a technological miracle for economically storing renewable energy.

<i>Rooftop solar is still losing, but yes renewables in general are still competitive</i>
They aren't though, how many people do you know with an electric car, solar panels, a battery, without a grit tie? AKA they get all their power from renewables?
I personally don't know anyone like that, although I know plenty of people with solar, an electric car, or even a small solar+battery setup.
Why is that, because its super expensive, the tesla will be the cheapest part of the equation when your done.
And that applies to PV and wind at grid scale too, because for every MW of PV+Wind being installed there is a MW of natural gas plants being installed. So the actual cost of a wind turbine isn't just the turbine/panel, its the gas plant and its fuel. Which means that until we get magic pixie dust batteries that are less expensive than a gas plant, the price of wind or PV will never really go lower than whatever the cheapest backup source is. And that is the fundamental issue with the economics of solar/wind. Worse, battery costs can't just be added in because one has to take the duty cycle of the renewable source and multiply it enough (maybe 5x-10x) to get a 100% average duty cycle sufficient to charge those batteries.
So, at this point to get a rough approximation of the price of wind + PV needed to compare it fairly against the legacy power generation one needs to multiply by maybe 10x. And that is why every random person with a farm isn't covering turning their land into power generation.
So, maybe solar thermal solves the battery problem, but AFAIK its crazy expensive at this point too.
So, we keep pumping carbon out our tailpipes because we can't even get renewables to grow significantly, nevermind actually dealing with the impact of doubling or tripling the electric production needed to heat peoples houses and charge their cars.
The only question is how many more decades we will pump C02 into the atmosphere before we say enough, and either dump massive amounts of money into renewables, deal with grid instability, and try to "conserve" out way out of a crisis, or just get out of the way and start reprocessing the "waste" we have sitting around into new plants that can for a small fraction of the construction costs actually solve the problem.

My "still competitive" remark was in reference to deaths per kwh. But to your point, I'm not sure what the deaths/kwh are if we factor in the supplementary natural gas / battery / etc required to bring renewable reliability up to par with nuclear.

Isn't this precisely the metric you want? If you want to convince me (and perhaps others as well), I think you need to go a little more into the details why this is a bad thing. It's not obvious to me.

Related to my above point, should it not be expected fatalities over the projected lifetime of whatever plant/turbine/etc.?

Only for the first wind turbine. For your Nth wind turbine, you sum all the TwH generated by all previous turbines as well as their deaths, including those ritual sacrifices.

There is no way in even napkin math for this checks out. The amount of construction per generation capacity is orders of magnitude lower for nuclear. For nuclear you build one fancy concrete box and then feed it a fairly minimal amount of fuel for 50+yr. With wind and solar you need far more expansive facilities for equivalent generation capacity and you need to replace them far more often.
Even if you assume a zero carbon supply chain the larger supply chain means that solar and wind have a far larger environmental impact (more mines, more factories, more roads, etc, etc, etc).
Considering the amount of lip services paid to externalities in these sorts of conversations I don't know why this point keeps getting missed but I will note that is is very convenient for some people to miss it.

The problem is the nuclear construction is much more finicky.
You screw up 1% of the modules in a solar field, your output is down 1%.
You screw up 1% of the welds or concrete pours in your nuclear plant, it's time for enormous pain.

Exactly this. And even leaving out deaths and the high long-term environmental uncertainties of nuclear waste storage, solar and wind are already cheaper and will continue to get cheaper for the forseeable future.
Now, people will say "bUT tHe sUn dOeSn'T sHiNe aT NiGhT", and that's true for the moment. Right now, we cannot shift everything to solar and wind. But if you pay attention to battery development, you don't need to be Einstein to see that pretty soon, we will be able to cost-efficiently store large amounts of energy, distribute it and use it in a way which will solve this intermittency problem.

Meanwhile nuclear plants come with months worth of energy storage, as fuel is storage.
For long term (like seasonal) variations in wind/solar output, you're probably not going to be building enough batteries to bridge that gap, so to stick with just wind/solar you would need to either overbuild (perhaps massively) your generation capacity, or build a global grid.
A global grid introduces geopolitical risks (your neighbor becomes not-so friendly and cuts the link when you don't have sufficient generation), whereas massive overbuilding would be expensive. Having some nuclear plants may be cheaper route.

There's a solar panel field I go by occasionally. Last time I saw them, all the panels were covered in inches of snow. I guess nobody bothered clearing them off since we can have weeks go by without much if any direct sunshine in the winter, and windy days are equally infrequent.
I don't know how many batteries it would take to make up for the losses. I suspect we will have gas and nuclear plants for a long while yet.

That's very anecdotal, I'm sure that most solar panels are not usually covered by snow.
You do realize that there exist countries where it snows regularly? When that happens, even if it’s just 1 week/year, you require battery capacity to cover that one week.
Panels are black, slick, inclined and warmer than ambient. Snow accumulation is generally not a problem.
Thanks for the link.
Maybe you have data on:
- total installed storage capacity as percentage of daily electricity usage (preferably 95th-percentile daily usage). Hopefully this percentage increases every year.
- how often should we expect to replace batteries. Wikipedia says 400-1200 cycles. Does this mean that whole world storage capacity must be replaced every 400-1200 days?

Hey, I know that anti-nuclear views are not popular on HN. But instead of downvoting, why not engage with the data and facts that I linked to? If it's because of the funnily capitalized sentence, come on, don't take everything so seriously.
Your link is very light on facts. E.g how much cheaper batteries would need become to be competitive with gas/coal/nuclear and is that even possible with lithium batteries alone?
But how many millions of tons of soil do we have to shift to get the lithium for all these millions and millions of batteries, versus a few kilos of uranium?
And it's the same with the turbines and all the rare earths that need to be mined to make the current most efficient dynamos.
If people want to promote wind turbines and solar, they should at least compare like for like, which includes the costs of digging the materials out of the ground, and the disposal of old panels and turbines, in the same way people say 'but nuclear waste!'.

Yes, I agree that we need to include all costs. But, to my knowledge the costs presented in the link I sent to include all costs, e.g. here for batteries: https://ourworldindata.org/cheap-renewables-growth#batteries...
I'm not disagreeing that batteries are cost efficient, just pointing out that batteries aren't (natural) resource efficient.
Sure, but digging for Uranium isn't a walk in the park, either :-) I'm just pointing to the fact that if the data in the Our World in Data does in fact inclulde these costs for both our cases, then it's still clear that the costs of renewable + battery is cheaper than nuclear and still on a strong downward trend.
Nuclear is also the most expensive energy source (total cost per MWh). Which is the real reason why "Europe is losing nuclear power".
When finished the UKs Hinkley Point C nuclear plant will probably have cost around £23 billion for ~3.000 MW which is completely insane.

Well those are 3000 real MW. Not 10% when the weather is good and 0 otherwise. And it can be piloted as needed.

Let's do some math. You can build a 3 MW wind turbine for around £2 million. Which means you could build around 11,500 wind turbines with the amount of money spent on HPC. Which in turn means a maximum production of 34,500 MW. So even under the assumption that these will run at below 10% of their capacity you're still producing more electricity than HPC. Now in reality this number averages around 30% actually. So the price per MWh is orders of magnitudes lower compared to nuclear.
This is still not equivalent because we haven't solved storage (peaky energy is not as valuable as constant energy) [and because you've compared build costs to total costs].
Bit in [] is false; apologies.
Bit in [] is false; apologies.
Yes, there needs to be more storage or backing by gas plants. But nuclear power needs the same gas plants as you cannot change the output levels quickly enough to drive the grid. In a sense, constant output is almost as bad for the grid as peak energy, which can easily be throttled.
In both cases you need additional flexible plants or storage. In the moment, when there is true surplus renewable energy production, storage buildup will increase quickly.
Side note: electric cars will be a large part of the grid balancing in the future.

Do you have any good reading for this?
In my naive mind, it’s doomed by the fact that we drive to work in the day, then all come home, together, in the evenings, when the sun is on its way down. Or is the plan to have two way power chargers at businesses too? Otherwise, all these batteries are disconnected when you need them.

Considering how much storage capacity becomes available when connecting cars to the grid - even if the part used for grid storage is only 10kWh/car (typical batteries have 70 or more kWh) - I would assume there will be a huge push by utility companies to get as much cars connected as possible.
Sure, but assuming all of the office buildings of the world don't retrofit their parking structure with grid connections, these cars will only be connected to the grid in the evenings. I suppose this would be great for taming the dinner time spike, but it seems to put the availability, for them to store excess, where it's needed least: https://www.researchgate.net/figure/California-daily-utility...
Why would you assume that no office building would retrofit their parking structure when there are huge incentives to do so?
For sure not all of them might, but if enough do, it will be a major benefit.
But yes, if a car isn't connected to the grid it cannot participate.
> Why would you assume that no office building
I'm definitely not assuming that none will, I'm just assuming it will be a some smallish fraction for the foreseeable future. Nearly 50% of California's working population works for small business. It's not just the cost of the equipment, but also cost up upgrading the panels and, almost certainly, service lines.
Where I am (a city in California), you have to pay for replacing the service lines/conduits, including digging it up/repairing the street and sidewalk, even if they run 1 city block.

Do the math on this too. How much storage would half of $21 billion buy?
https://insideevs.com/news/458106/battery-cost-110-kwh-price...
Using a pessimistic $150/kWh (it's already under that) I get 70,000,000 kWh or 70 gWh, enough to run the entire state of California for a little over an hour. So you could build over 10GW of wind power capacity and 70 gWh storage for the cost of one nuclear plant.
Nuclear isn't dying because of hippies. It's dying because it's expensive. You're right that the safety concerns are over-inflated, but failure to deliver on its cost promises are the major failure of nuclear (fission) power.
If we make fusion work and can scale it, that's a totally different ballgame... but it won't happen fast enough to impact climate change.

I really don't think this isn't about maths with money. People are constantly working on this as-yet unsolved problem. Those batteries aren't suitable. Perhaps some will be one day, and that will be the fix.
But in the meantime, the best option is nuclear.

I've compared the build costs of HPC to the build costs of wind turbines. Not total costs.
You're right. Will edit.
But! But. What's the source for the turbine build cost? Now I need to try and attack that :)
> 11,500 wind turbines
That's a lot of space used.
And don't forget those wind turbines will have to be replaced after 20 or 30 years while your nuclear plant is good for 50 to 60.

The largest onshore windfarm has 240 wind turbines (https://www.wikiwand.com/en/F%C3%A2nt%C3%A2nele-Cogealac_Win...).
You can't just easily build 11500 wind turbines without huge impact on environment.

That’s not quite fair. If we were building 11,500 nuclear power plants their unit price would be much lower too.
Part of the problem is that nobody has built the things in the past 30-40 ish years.

Though falling prices would be intuitive, with nuclear that's been found to be false, both in the US and in France. Building subsequent versions of the same design increase in cost, rather than staying the same price or going down.
France: https://www.sciencedirect.com/science/article/abs/pii/S03014...
US: https://news.mit.edu/2020/reasons-nuclear-overruns-1118
This is truly remarkable phenomenon that occurs with almost no other technology. And this happening in France rules out the possibility that it's merely increasing regulatory burden that causes increasing costs.
Those who want us to build new nuclear need to grapple with the issue of their cost if they want it to happen, yet I have not found a single nuclear advocate on HN that will acknowledge that these issues even exist, much less bother to propose some solution.
At least for the "safety" issues, we can have a discussion about how designs can mitigate that. But there also needs to be discussion on how design, workforce training, logistical management, or something can improve the construction issues.

If you build 11,500 nuclear plants they will have to be breeder reactors (or, we'd have to deploy 2 million square miles of uranium collector fields in the ocean if that could be made cheap enough to supply U for burner reactors.) We don't use breeders because they've proven to be more expensive than LWRs, not less expensive.
> £23 billion for ~3.000 MW which is completely insane
3000MW almost constantly, for what, 60-80 years? How much would the equivalent wind+ grid scale storage(multi-day) that would need to be replaced multiple times over that same lifespan cost?

Refueling outages last on average for about 2 months every 18-24 months, so it's never been "constantly" really.
And it's still the most reliable power generation method by far.
Well, might be. The question is though if it's worth a price orders of magnitude higher than competing energy sources. And most countries on this planet seem to have come to the conclusion that it is actually not worth the price. Now I am actually not particularly for or against nuclear power - just making the argument that it's not an economic source of energy anymore.
If it's not economically viable, then there's no need to regulate against it, as no one would build it.
However we see many governments blocking nuclear and even shutting down current plants. Why is that?

The already build reactors are the cheapest energy source. If you close reactor stupidly early, like 20-30 years after build, you're throwing out next 30-50 years of generation that cost basically nothing.
And unfortunately, of that £23bn, something massive percentage will be government "bureaucracy" for want of a better word. If nuclear power were properly commercialised it would be cheaper. The only analogy I can think of is cost of launches for SpaceX vs NASA or ESA. SpaceX had to be efficient and make a profit, they innovated, and now are the cheapest launches available by a huge margin. Governments are always interested in nuclear for "security" reasons.
The article indeed mentions modular commercial reactors.

It is very simple, nuclear has been a failure in Europe in the last couple of decades. Look at projects in the Finland, France and the UK. The situation would have been much better if there was a nuclear industry that could deliver in time and within budget.
A country like France with a massive amount of aging nuclear power plants is in serious trouble replacing them in time.
Fortunately, wind and solar are doing very well in reducing CO2 emissions. In the coming one or two decades, wind and solar can easily outpace nuclear in reducing CO2 emissions.

This is not a fight between wind/solar and nuclear. This is a fight against coal. You should reduce the coal first, not nuclear.

Ultimately, this is about money.
For aging nuclear power plants, keeping them running becomes more and more costly. So the question becomes, if we need to invest a big chunk of money, what should we invest in to reduce CO2 emissions the most.
And the answer is that building out wind/solar and insulating buildings is at the moment way more effective than keeping old nuclear power plants running.

Well, it's not really, if it was just about money all the research that went into renewables could be invested in other things and we could just keep burning cheap available coal. It's about stopping CO2 emissions and we need every drop of capacity we can get if we are to shutdown fossil fuel plants. Trying to eliminate both fossil fuel usage and nuclear at the same time is insane, and we are going to miss our already lax emission targets because we are taking on a handicap for no reason.

This is already what we have been doing, and that's including that we can "make do" with energy savings.
It just doesn't close the gap. Nordics/northern europe need nuclear or equivalent power source to close the gap, or a revolution in energy storage.
I think we need more energy in the future, for all the green technology, not less. Energy is the currency, even more so than already, of the future economy.

The problem we have is that in the past decade fossil fuel was way to cheap. This has now changed, but ramping up production of solar and wind takes a while.
Fossil fuels are still way too cheap compared to storage of electricity. So there are lots of ways we could store electricity. But if you can't compete with a gas powered plant next door, it is not going to be built.
At the same time, if you look at power consumption of data centers, it is amazing that so much of that can be ad supported.

The proof is that nobody is investing in keeping old nuclear power plants open. All over Europe. When those plants stay open it is governments paying for it.
In contrast, companies are now paying money to rent a piece of sea to put a wind farm in.

Agree 100%, but this isn't in the context of one or the other, it's in the context of doing the maximum of both.
Sites that want nuclear and have the extra money for it should go forward full steam ahead, but current construction capability in both the US is extremely low. Even at maximum build capacity, neither the US nor Europe will be able to build at the pace they had in the 1970s. And as the 1970s-era reactors reach natural end of life, we won't be able to replace them as quickly as they leave the grid.
In contrast, renewables and storage deploy quickly, on time, and on budget, and the capacity for production is at least an order of magnitude larger than what we can do with nuclear.
This isn't an either/or, it's a "yes and" but it turns out that nuclear's contribution will be fairly small in comparison.

Could you be a bit more clear about your implication here?
Do you think the EU energy crisis is because of renewables somehow? If so, how did you come to that conclusion, and in what way?
Renewables don't generate any energy when they aren't connected to the grid. And natural gas shortages for heating don't really get solved by renewables unless people start installing lots of heat pumps, which they definitely should.

What are the reasons for that failure? Has Europe had the same problem as the US of severe under-investment in infrastructure and withering capabilities? Is risk-aversion becoming pathological, leading to ballooning costs and complexity?

It seems to be a combination of nuclear becoming too high tech combined with not enough volume to maintain the technology.
Maybe its a scale thing. If you build only a few nuclear plants per decade, you can't iterate over designs. You may lose valuable knowledge, etc.
If I look at complex building projects in The Netherlands, it seems that beyond a certain complexity, companies just cannot come up with a design/plan to make it work.
For example, the Dutch government said, we want the biggest lock in the world (https://nl.wikipedia.org/wiki/Sluizen_van_IJmuiden#Bouw_nieu...). Not a controversial project, yet the winning concortium had a design that didn't work and had quite a few other problems.
On the other hand, windturbine designs iterate so quickly, that even floating turbines in rough sea is now economical.

Germany has proved this is a huge lie.
Edit: to elaborate a bit, what it proves without surprise is that wind and solar can't significantly reduce CO2 without a clean baseline. By their very nature (not producing at night and without wind), and without some miraculous tech breakthrough, wind and solar can't be the major part of the mix for our developed societies, that's the hard reality of the orders of magnitudes involved here. So the question is what is the realistic plan for that baseline to complement solar and wind for at least 50% of the mix? Because the only options I see are A/Nuclear, B/Bet on imaginary storage tech, C/Bet on fusion becoming viable with decades earlier.

It's the other way around. Without wind and solar, Germany would produce a lot more CO2 than it produces today.
If you come from a situation where most electricity is generated from fossil fuel, with a bit of nuclear, than installing a bit of solar and wind trivially reduces CO2. Wind on the North Sea can trivially take 50% of all required electricity production.
It is the end game that is hard. With just solar and wind you can't go down to zero CO2 emission.
That said, it is not clear that you can go to zero CO2 with just nuclear. Unless you are massively overbuilding nuclear to deal with peakload.
The current problem is that no government has proposed a timeline when fossil fuel will be more expensive than storage (or than nuclear mixed with wind).
As long as fossil fuel is cheap, we will only see solar and wind, because those are currently cheaper than fossil.

Sorry but no this is not what I call “very much”, nor “very well” as GP said. If you look at all the fossil bars (don’t forget the gas that would be too easy) it further prove my point that Germany really failed this decade and the trajectory is not looking good.
Also for a reality check have a look at electricitymap.org when there is no wind and when it’s the night, I don’t see how ones could keep a straight face thinking they are doing good, this is the mix of the future for our cities.

Can you explain the 'not looking good' part?
I see in 2002, Gas+Oil+Coal+Nuclear = 450 TWh. Then in 2021 this amounts to 262.98 TWh.
So both nuclear and fossil fuel went down quite a bit.
Looking just at the fossil fuel number, they went down by 96 TWh during that period. Seems like a significant win to me.

Well, nuclear power plants are not every easy to build. It takes time, knowledge, and experience. US/UK/French experience slowly degraded after this extended period of nuclear hatred. Now, when NPPs are cool again, they realised they lost core competences!
Note how Russians never stopped building NPPs so they do manage to build on time and within budget.

I can only speak for myself but I don't think nuclear power is bad, and I don't connect it with nuclear weapons or even deaths. It's just scary. And that's due to Chernobyl and Fukushima. And I haven't dug into the technicalities of why one of these new level 5 grand wizard mosfet reactor types can't fail in 50 years like the old ones did. Because we are smarter now? But if I look around at the current state of affairs I would say it looks like we have started to walk backwards as a civilisation. Not a rational thought I know, but it nicely feeds into that first ingrained irrational fear.

Fukushima wasn't that bad. Very little radiation was leaked and the max number of expected cancer cases expected based on conservative modeling is ~100, mostly of the treatable thyroid variety. Most of those people will likely die of other causes.
Chernobyl was just an idiotic design that no one outside of the USSR would have built after about 1954. Graphite piles are death traps, and not building a containment building is insane.

Fukushima as a plant was also asking for trouble: "the earthquake had also generated a tsunami 14 metres...swept over the plant's seawall" (c) Wikipedia. 14 metres is a joke for a country where 40 metre tsunamis happen.
It is amazing how this could be built not taking high waves into account.

This what happens when politicians control the placement of nuclear plants. The scientist and engineers picked a much better location for the plant, but were overridden, and a political favor moved the location.
The engineers mentioned they needed a large seawall to protect the plant from the frequent tsunamis, and were overridden because it cost too much.
Nuclear can be safe, but you have to keep politics out of it.

Yeah, and even that would have been fine if backup power in plant one hadn't been in the basement. The other, newer reactors had above ground backup power. Either a taller wall or a generator in a shed would have prevented the accident.
Well, part of it is that there is a lot of FUD about nuclear.
The impact of Fukushima accident is a grand total of 0 deaths.

If we talking about technology development than each technology has ups and downs but very often there is a gradual improvement, peak and then slow of fast fall.
I don't think nuclear energy passed its peak and degrades. Newer reactors are better than 50 years ago. The only think which can be worse - ever increasing amount of regulations added without cost-benefit analysis. Safety by any price is a dubious goal because the price may be too high to pay.

Nuclear had roughly 60 years to deliver clean, cheap and reliable energy. If it did all that, no amount of green lobby could have derailed it. Unfortunately, and I feel that deeply as an engineer, it did not achieve those goals.
What we have currently have are slightly evolved designs over those of the 60s, which are fantastically expensive, take up to a decade to build and three more decades to recover investment, and present a large economic failure risk - see the Nukegate fiasco. No sane financial investor wants to approach nuclear, no one wants to insure it, so the only ones willing to eat the risk are states.
Yes, we had a window in the last 20 years to reinvent fission, have new, secure and cheap reactors which cannot proliferate, are passively safe and fast to deploy. The industry and regulators remained paralyzed, structurally risk averse. That window has now closed.
Renewables are cheaper then nuclear, fast to come online and have very low risk. Storage is quickly dropping in price. Together, storage and renewables, coupled with a smart grid, will be able to cover more and more of the demand and require fossils to be fired less and less. It does not matter if you go fosil for a whole week in a year where there is no sun, wind or rain, that's still only 2% of the production and you can use very expensive mitigations like CCS, as long as you have cheap renewables in the rest of the time.

I don't know where you're from, but in France, we did it.
Electricity was, and is still, rather clean, and cheap, and reliable, thanks to nuclear (see https://app.electricitymap.org/zone/FR ).
And the most striking example of that is how terrifying the rise of cost of electricty is coming ahead for consumers and enterprises, mainly because of other energy sources, rather than because of nuclear itself.
Renewables are all nice and thanks (and definitely to grow and improve), but they cannot, from a long way, deliver the sheer and stable massive amount of base energy that nuclear can.
Without monstruously large storage capacities that we don't have today, cutting ourselves from nuclear is a civilisational collapse guarantee.

Sure, when you disregard the initial investment cost and only look at the marginal nuclear is among the cheapest. Although still being undercut by new investments in renewables nowadays.
That is the issue at hand, building new nuclear is not only marginal cost, it is mostly fixed costs and a unfathomable initial investment.
That is the issue at hand, building new nuclear is not only marginal cost, it is mostly fixed costs and a unfathomable initial investment.
The question is rather: how do you expect to get rid of nuclear energy production in the coming century AND reduce CO2 emissions AND not get energy blackouts and prices soaring to unimaginable levels?
France did it
"so the only ones willing to eat the risk are states."
Sure, if you can cook the accounting books to pay for a military nuclear industry, and also get a civil sector that has no need to pay for capital, insurance and cleanup. I doubt it's a scalable model, and France had its own share of fuckups and close calls.

In the UK, every single time there's been a proposal for a reactor, there are local protests, and CND/Greenpeace turn up en masse. There's been no opportunity to deliver 'cheap' energy in terms of up-front cost, because there are so many artificial hoops to jump through - legislation, planning, and so on.
As for clean and reliable. No CO2 right? And the nuclear power stations in the UK pretty much have run continuously since they were switched on, so I'm not sure what 'reliable' means here.

Thanks for calling us brainwashed.
First, show us what is the progress in nuclear waste treatment. (None)
Show us the data of long time term safety of operating nuclear plants. (Every decade we have an unmitigated disaster, even with so few operating nuclear plants)
Also please show us an economically viable plan to keep sourcing Uranium for increasing demands. (Ideally one that does not involve waging wars)

If you would let somone collect #2 ;)
For sure I can understand that maybe nuclear power plants from the 70s don't have the best security for today's standards. But based in the technology leap from the 70s until today, I can imagine that a nuclear power plant being built today are much safer than those from the 70s. And you are right, death numbers by nuclear energy accidents is much smaller than with Nuclear. UN says that not more than 50 person died in Chernobyl[1]. In Fukushima: 0[2].
However that's maybe like accidents with Cars x accidents with Airplane: The statistics are irrelevant for people with intrinsic fear from Airplanes.

All those things may be true, but they still count against nuclear energy. Lack of public support and lack of continuous development make building capacity more difficult to deploy in the present. Technical superiority is not enough.
ironically, that same could now be said about our gas crisis in Europe, where we handover immense leverage into the control of Russia.
Nuclear power is not a solution to climate change. It would bind too many resources (which are also finite in economical quantities). Last year the first permanent storage worldwide opened, it is not a solved problem. Nuclear processing plants have elevated cancer rates around their location and it is still legal to dumb contaminated water into the ocean. It was only restricted for barrels.
The construction costs are very relevant, not only from a CO2 perspective. Nuclear power is not very attractive, only if you reduce environmental protection to CO2 output, which is insufficient. So no, the greens of former years were not that wrong. It is questionable to shut down working plants, but if nuclear was that feasible, it would already play a larger in energy production today. If you start building plants today, you will need at least a decade to get them operational. You can look at France for the youngest examples of that.
And would you want to mine Uranium? Have fun with that.

The technology for addressing baseload exists: renewables, batteries, and long term chemical storage (like hydrogen). All these exist, it's just a matter of pushing the costs down via deployment and experience.
If you object to these because they are not scaled out, I will point out that a nuclear powered world will also need new tech of that kind: either seawater uranium extraction on a massive scale, or a breeder-based fuel cycle. Existing burner reactors would, if they powered the entire world, exhaust available uranium resources in just a few years.

Part of the problem with Nuclear is tax payer exhaustion. Every time they build a plant it take 10-20 years longer and cost over runs are in the billions. And then you have costly refurbishment that runs into the billions and takes half a decade longer than anticipated. It's a shit show from day one until they finally shut it down 20 billion $$$ later...
even then it's still a shit show because someone has to play for cleanup and storage and the nuclear company usually goes conveniently bankrupt soon after they stop producing energy.
> has been responsible for smallest number of deaths of any form of energy generation
So far. The spent fuel will be around for another 10k years to potentially cause further deaths.
If we have a few more Fukushimas, we might ruin the ocean forever.

I could be wrong, but, IIRC, coal power has actually created more radioactive pollution than nuclear energy. It's just a far, far larger volume of less concentrated pollution.
Also, Fukushima-style pollution isn't "forever." The most radioactive stuff also decays the quickest, so it disappears relatively quickly. It looks like most of the pollution from Fukushima was caesium-137, which has a half-life of 30 years.

There's no small irony that after Chernobyl, all evidence is that animal life has actually thrived in spite of the radiation, and if anything, the most sensitive species to radiation is us. Another commenter has already pointed out that there is vastly more radioactivity in the sea than anything we can add.
A few million gallons of nuclear contaminated water into the ocean is nothing, it'll dilute to next to nothing, Nuclear homeopathy, if you prefer.

You need to include the risk, cost, and near and long term consequences, of catastrophic failure in your analysis. That may alter the conclusion that N.E. is 'the least worst option'.

Given that japan had a giant radioactive ocean leak and I still haven't heard comprehensive reasoning about why we think facilities for storing nuclear waste will not be slowly defunded, I think the scare quotes can go. Politics anywhere (at the moment) simply cannot be trusted to properly manage nuclear waste, so we should not be producing it.

The alternative is producing emissions from coal and oil which we just dump into the air.

I wonder how much of the green movement of that era was supported by the Soviets, who had obvious motives for undermining nuclear research in the West. I could be that even long after the USSR has been wiped away that its influence remains.
Don't think so. Taking Germany as an example, many people joined these movements after the country was in large parts affected (to this day actually) by the nuclear fallout of the disaster in Chernobyl. So I guess experiencing this first hand made a huge impact for many people. Personally I don't have a very strong opinion on nuclear (neither positive nor negative) but I also believe that you can't simply take these experiences away from people and it would be wrong to invalidate them.

I don't think those things are mutually exclusive. It's quite conceivable the Soviets supported a seed, which sprouted once Chernobyl created the right conditions for it to take off. It looks like the German Green party opposed nuclear power before Chernobyl and it was also infiltrated to a degree by the East German Stasi.

And now you know why Russia supports Green Party in many countries. Such support can advance many geopolitical goals, from undermining the party opposed to your interests, e.g.,[1], to undermining forms of energy opposed to your interests, as here. How convenient is it for Russia that Germany could really use the nuclear power that was removed in no small part to strong opposition lead by the Green Party, and just as Nord Stream 2 gas pipeline is nearing completion, tying Germany's entire economy to paying Russia for energy for the next few decades? It is not a coincidence.

Yes, the RUS support does seem to have switched, they were supporting DE Greens in the past, not sure why the change, haven't followed it closely enough. Maybe damage (to nuke industry) already done, and they needed to amp up support for importing fossil fuels, which wouldn't be credible for Greens to support. As far as I can tell, it's all opportunistic, laying groundwork for whatever might work in their favor. Since I don't have copies of the checks, it is also possible that the Greens merely played the role of Useful Idiots (in the V. Lenin definition) and happily helped with RUS goals.
It is - frankly - shocking that elite culture has drifted so far into the world of make believe that something as simple as energy security has become a political battleground. If there was a single issue that the entire political body of a country has a stake in, that is the issue.
And yet, somehow, we're seeing Europe in this position where they're trying to go it without energy. The figures out of the UK [0] are jaw dropping to me. 44% reduction in energy production, 20% in electricity and with a growing population!

Also as a brit, there is some other truly mystifying things happening with gas.
I was reading yesterday how despite the gas price explosion we are seeing, which is crippling for many low income households, we actually exported twice the quantity of gas September - November 2021 than in the same period in 2020. Clearly privately owned gas companies currently have the right to sell to the highest bidder, even if it is oversees. But, right now, the UK government needs to be addressing the cost of energy crisis that is impacting its citizens and it isn't a supply issue at all.

Maybe it's needed more "overseas" if they are paying more? Seems like the market is working.
I think the people of the UK who are struggling to afford to heat their homes this winter would disagree that the market is working.
I generally agree with free markets but I also believe the government should step in and regulate, impose restriction or cut taxes when their own people are suffering.
I generally agree with free markets but I also believe the government should step in and regulate, impose restriction or cut taxes when their own people are suffering.
I agree that there are cares where the market needs to be directed into the right direction because incentives are missing. Natural monopolies immediately come to mind and if course not paying for negative externalities.
Where I disagree is when we try to manipulate the market to lower prices so that poor people can afford it. Let's stop screwing with the market when not necessary and just make sure people have the needed money to get by. Ultimately that will need cheaper in total. But costs would be obvious instead of hidden ask it's politically hard to impossible.

Do we even produce much gas? Maybe we are, on paper at least, buying it from Russia and selling it to Germany or some such.
About 40 billion cubic meters (bcm) annually in recent years down from 100bcm in 2004. I believe mostly from the North Sea. We use about 70bcm per year and so are net importers, which makes the fact we have increased exports during an energy crisis confusing.
I believe the stats on exports are exclusive to exports of what we have “produced”.
From my maths we exported about 3bcm of gas Sept-Nov last year.
My understanding from memory is that the oil/gas companies licence the right to drill in the north sea from the Crown (effectively the government). I believe the Crown estate “owns” the seabed, or something like that.

Maybe, but those of us who grew up in the wake of Chernobyl are likely never going to support nuclear power regardless of the facts. You can ignore that fact, but that doesn’t mean society is somehow magically going to readjust to what is “right” or “scientific”.
I say this, not in defence of the anti-nuclear generations of Europe but more so to explain why the political climate is how it is.
Beyond this comes money. Our technology sector is invested in basically every sort of green energy, except for nuclear. All our advantages in making money lie in things like wind and solar power, and if we were to truly adopt nuclear power, it’s very likely that all that money would leave Europe and go into Chinese or Indian technology. Which may be great for the planet, but you’re just not going to see European politicians stand in line to transfer energy sector jobs in the hundreds or thousands out from Europe.
It is what it is, but this isn’t likely to change in the next 40 so years.

Fortunately (at least in my opinion) this is changing, Rolls-Royce are developing new "mini nuclear reactors". We have the technological expertise and it looks like we are beginning to see the political and financial motivation too.

Yup, Brit here. It beggars belief. And the leaders will continue to be so stupid, because the other party will also make this mistake too.
What happened to the nuclear reactor built with the help of China, with George Osborne's approval?
It is still being built and they have a very good deal that means every house hold in the UK will be paying over the odds to give it guaranteed profits for decades to come.
per ofgem, wholesale prices have been greater than Hinkley's £92/MWh since October.
And that's before we add heating to the winter electric load. Conservatively, and I am really trying here, you're doubling grid load. If we go by my household, you're adding a zero.
I can find multiple >12 hr periods in this fairly mild winter where wind has essentially failed on demand (<5% satisfaction). I'm sorry but if someone says "storage" when talking about even that sort of shortfall they're lying.

yeah, you need a supergrid and to import the electricity from southern spain during low wind periods in UK.
France goes through similar bouts of having to import because so many of their nuclear plants keep having to offline at the same time.

I think people these days are really disconnected from the real world. Earlier generations lived through wars, saw extreme poverty, food and energy rationing. Now people have never lived without anything important.
This is not an elite thing.
In the countries where nuclear is shut down / being shut down it's often so with large majorities in public opinions supporting it

That's why we use representative democracies, sometimes tough unpopular decisions are needed for the "greater good". The majority of public opinion would be against a tax hike to fix infrastructure that's falling apart or new nuclear power plants, but both can be vital ( or otherwise people die by bridges falling apart or pollution).

No matter how you cut it if your definition of elite says that absolute majorities at the ballot box / in opinion polls are elites it's either wrong or not a very useful definition of elite
You can also reliably interchange the word "elites" with "people whose opinions I don't agree with" and you'd have a slightly more honest assessment.
Politicians and the people who support them push for many self-damaging policies based purely on ideologies, just because they sound good (getting rid of nuclear, going green) without considering the direct consequences of these actions (how do we serve our energy needs until we become fully green?).
That's like selling both your kidney to buy a prosthetic robot arm and wonder why you're not feeling well despite the upgrade. Sadly you can't argue on the pros of nuclear as you'd get drowned out by the "But Chernobyl blew up" shouts.
Rich anti-nuclear countries like Austria call themselves green while supplementing their energy needs via imports from coal burning Czech Republic and nuclear powered Slovenia. Laughable. This loophole in the EU should be stopped. If you import dirty energy you should also be responsible for the equivalent CO2 emissions you imported and not be allowed to call yourself green when clearly you just outsource your pollution.

And the best example of that in Germany is Hambacher Forst. Return to coal is a direct result of moving away from nuclear. Nuts.

It's not, really. You can actually see that both nuclear and coal have been replaced by wind and solar in Germany. The issue about Hambacher Forst is politics and political lobbies. The area is owned by RWE since the 1960s and the open pit mine next door exists for much longer than the decision to get out of nuclear. It's simply convenient to blame this on the "Atomaustieg" as part of a lobbying campaign.
It's also interesting that nobody was saying that the Atomaustieg was responsible for increased coal use in 2020. Because it's only last year that was an exceptional year, which saw a uptick in coal vs wind.

Coal is still the primary source of energy for Germany.

Germany did not return to coal. That's simply not true. The coal under Hambacher Forest isn't even needed and it won't be used up either.
>Germany did not return to coal.
Germany's buying cheap energy from coal burning Poland so it might as well have.
Call it outsourcing of coal burning if that makes it easier to take in.

A net import of 250,000 MWh in the past month. That's not even 1% of Germany's electricity production. Germany produced 4x as much electricity from photovoltaics even though the sun wasn't shining.
And because it won't be used and is not needed, the mine will operate until 2038?

I'm a Czech hence biased, but hey we've got two nuclear power plants! (and yes the Austrians hate them)
According to Our World in Data [0], Czech Republic is 15% nuclear while Slovenia is 18% nuclear. We both have different primary sources of power (Czechia coal at 37%, Slovenia oil at 39%). I take offense at your statement "Czechia coal Slovenia nuclear"!
If it weren't for Austria, we'd likely have more nuclear and less coal. We wouldn't have knoedel and schnitzel though, so perhaps it evens out.

The problem is simple. For decades, Russia was supplying natural gas reliably and for a reasonable price. Generating electricity with natural gas is trivial.
So shutting down old nuclear power and replacing it with wind/solar backed up by gas was not a crazy idea.
Was is a crazy idea is then letting 'the free market' take care of the gas supply.
Where is gets more complex, natural gas is not just used to generate electricity, but also to provide heat for lots of homes. Keep old nuclear power plants running doesn't do anything for keeping people warm.
In short, Europe has a natural gas problem, not so much a nuclear power problem.

"According to the International Atomic Energy Agency, about 43 nuclear reactors around the world—mostly in Eastern Europe and Russia—provide district heating in addition to generating electricity." (https://www.powermag.com/district-heating-supply-from-nuclea...)

You have to compare district heating to about 7 million households using natural gas for heating in The Netherlands alone.
So keeping a few nuclear power plants open has hardly any effect on the amount of natural gas that is used.

The big asterisk is that countries of the former Eastern bloc have the infrastructure in place. No one will keep old and expensive nuclear reactors around and build a district heating to millions of homes from scratch.

Russia now has a "war chest" of almost a trillion USD. Enough to pay off all of its debt and to run the country under complete sanctions for two full years.
This is 100% because the EU, led by Germany, decided to allow natural gas to be pumped in.

That's not how sanctions, or realpolitik/geopolitics work, yet of course you are right. Western politics is reduced to ~2 year cycles. At best there are overarching themes that continue for a decade, then the next crisis somehow erases everything, and some new thing captures the imagination, that we of course fail to carry on to fruition.

I wonder what they'll do when NATO goes to war with Russia over the Ukraine? I wonder if natural gas will be available at good prices from Russia then... even without the war Russia is going to be using that as blackmail for the forseeable future.
And on other side coal power plants are hit with expensive CO2 quotas.
What is it with framing this in terms of nuclear power. Many of the nuclear plants are being shut down because they are either end-of-life or were recently shut down because they were uneconomical.
Sure we can argue that we were not prepared for the recent uptick in energy demand as well as exceptionally low wind last year. However, one can just as well argue that this was a failure not to build more wind and solar capacity.
The bigger issue is that nobody wants to build nuclear power without massive subsidies, because it is simply not economical. So shouting now, "you should have build more plants" is easy, but that would have meant higher electricity prices, because that's what would be needed to economically run nuclear power.

This is simply not true. The main reason plants are being shutdown is because Germany, Belgium and Spain are closing them before end-of-life due to political pressure.

Is there a good source for the economics surrounding large scale nuclear fission reactors?
I'm interested to see what part is the gearing cost vs building at larger scale. A large part of the cost, some nuclear engineers told me, is that there is no more large scale industry in building large nuclear reactors. Investments have dried up essentially, so next generation plants pay a steep gearing cost.
I'm from a country with about half nuclear mix. The managing company has made around 1-2B EUR in profits last year, and that is with a special 1/5 tax agreement for keeping the nuclear reactors open for longer. So those reactors built in the 70-80s appear to have been massively profitable over their lifetimes. It remains to be seen how much the decommissioning factors in.

There are many large reactor construction companies globally. Many of the reactors being built in China, are being done so by French companies.
It's being framed in terms of nuclear power because the original arguments that led to this situation were also framed in that context. The anti-nuke movement of the last century directly resulted in this situation by preventing the construction of new nuclear power plants and in some cases cancelling existing ones such as the Zwentendorf in Austria[0][1][2]
Those decisions made almost half a century ago were shortsighted, emotional, and led by ideologues lacking the ability or the desire to realize the consequences of their actions which we are now reaping in the form of an energy crisis and an environmental crisis that has become much worse than it need have been.

Also don't forget to calculate the cost for maintenance, dismantling and safe storage of nuclear waste for probably hundreds/thousands of years.
We currently do not have _any_ viable solution other than "put it somewhere in a mountain" to get rid of nuclear waste. Nobody would propose a technology or product where this is the only solution to take care of the waste, nevertheless this seems to be fine for nuclear power.
What we really need to do is invest heavily in research and developement of storage systems of all kinds, building a more decentralized power grid (solar on every roof where possible e.g.) and getting rid of fossil fuels along the way. Everythings needs to run parallel, not one after another.

What's the problem with that? Radiation goes away, eventually.
The main thing that we should do is to reduce the amount of "nuclear waste". Spent rods are one thing, gloves that touched a facility with some amount of radioactive materials are another

Well, seems like a proper problem to me. What if something happens to those "safe" underground storages? What if radioactive material leaks into the groundwater reservoirs? There might be problems we can fix and control for say 50 years or so, like a generation long. But what after that? Maybe somebody has found a solution, maybe not. So bury it for another generation and hope the generation after that finds a solution? I don't like that as a "plan".

Wind and solar also have large subsidies right now, although the subsidies are decreasing. Nuclear should have been given the same chance as the other carbon-free forms of energy: subsidize it on its way up the S-curve, then drop subsidies after the technology is mature.
nuclear has always been more subsidized than wind/solar. It isn't enough. It's just crazy expensive.
I've seen the left (which is also the main culprit, coincidentally) push for this lie. Try asking someone high up in the nuclear industry, who wasn't politically appointed, and they will tell you.
It's mind-boggling to me that so commenters are blaming fear and brainwashing for the demise of nuclear power, when the answer is crystal clear in the numbers.
As of this year, the cheapest wind and solar farms have a lower total cost than the marginal cost of the average nuclear plant.[1] That means that in many places, it is cheaper to immediately shut down the nuclear plants and direct the money that was spent on operating costs into construction of renewables.
Yes, we should certainly keep the better-designed existing plants up and running, and build some new ones where the conditions are favorable, but in most places in the world it doesn't come close to making sense.

That Lazard presentation gets quoted quite a bit. There's a problem with it though: if things were so rosy, they'd happen in real life. You wouldn't get any energy shortages. Smart businessmen would just build those solar panels and wind turbines, and make a nice profit and also become environmental heroes in the process.
To some extend this is happening. California for example [1] had 1 GW or installed solar capacity in 2010, 13 GW in 2015 and 31 GW in 2020. But California is at a much lower latitude than any place in Europe (the average latitude in Europe is about 57 degrees, in California about 37 degrees). And it's also sunny.
Lazard doesn't say what region their LCOE is based on, maybe it's a global average. But then it's going to be biased towards southern latitudes by the simple fact that that's where most solar installations happen. And they happen there, because that's where they are profitable.
Separately, the LCOE does not take into consideration the fluctuations in the energy produced. And that's quite a big deal for solar and wind.
So, sure, new nuclear power plants are not economical, but just operating existing ones? In Europe, that most surely is.

The Lazard presentation isn’t some kind of rosy green energy fantasy, it’s written for energy investors who are making decisions today. Investors don’t give a damn about shortages, and will happily undercut everyone else’s business model if they can sell the cheapest energy the 95% of the time the wind is blowing.

Except that in this situation fossil fuel-based generators keep running.
We should be keeping nukes for as long as possible, and shutting down coal and gas first. The new renewable pick up the slack for coal/gas, and once all of the latter are gone then you start shutting down nuclear.

The problem with this line of argument is that there's no single "price for electricity". Either it's dirt-cheap when oversupplied, or eye-wateringly expensive when undersupplied. Within the past two months, spot price ranged from 3 cents to 1500 cents.
Renewables push down the cost when the price is already low, and do nothing when the price is high
Renewables push down the cost when the price is already low, and do nothing when the price is high
I think the people blaming fear and brainwashing for the demise of nuclear power are of the opinion that the prices are the result of the fear and the brainwashing.
Even if you fill the entire world in solar panels and wind mills, we won't have reliable 24-hours energy. That means you can't rely of constant supply of it, which means you'll need something as a backup.
Nuclear is one of the most reliable sources. The world has enough uranium for at least a few hundred years, which in practice could be much much longer depending on if we can keep installing more renewable plants. So, why not use nuclear as a backup? There is nothing even close to a better option than that.

I’m definitely in favor of keeping and upgrading existing plants and building some new ones, but there’s no source of energy that has 100% availability. A few years ago, France had 1/3 of its reactors offline at the same time for maintenance.
Indeed we would have to build enormous overcapacity with wind and solar to achieve 100% uptime, but until we perfect energy storage, that’s true of any energy source today.

And the wind stopped blowing several times today, the sun was only around for a few hours.
There's a clear difference. I invite you to think about it.
> Indeed we would have to build enormous overcapacity with wind and solar to achieve 100% uptime
Except, that does not guarantee 100% uptime, not by a long shot, regardless of how much over-capacity you build. One area not having wind usually means that there is no wind in a much larger area close to that. If you have wind in another part of the globe, that is useless to you because it can't be transmitted to your place; too much transmission loss for it to be viable.
Similarly, if you don't have sun, it is very likely that your entire hemisphere doesn't. So, it is crucial to have backups that are more reliable than that... and there is nothing that is better than nuclear for this... at least as of now.

If you have wind in another part of the globe, that is useless to you because it can't be transmitted to your place; too much transmission loss for it to be viable.
Similarly, if you don't have sun, it is very likely that your entire hemisphere doesn't. So, it is crucial to have backups that are more reliable than that... and there is nothing that is better than nuclear for this... at least as of now.
Yes you can in theory power the entire world with renewables. The sun is always shining and the wind is blowing somewhere. Of course, doing that would be stupid because of the diminishing returns.
But the same is true of nuclear power. Not even France tries to provide 100% of power with nuclear, because it would be an absurd over-investment to handle a few peaks or unexpected maintenance periods.
It’s pointless to argue that renewables can’t provide 100% of power, because in theory any single source of energy could, and in practice no single source of ever should.

This is a big false equivalency. Nuclear uptime is orders of magnitude better than solar or wind.
Capacity factor for wind at sea (North Sea at least) is typically above 40%.
So nuclear can be at most a factor of 2.5 better. Given how cheap wind is, you can easily overbuild a factor of 2.5 and still be cheaper than new nuclear.
So nuclear can be at most a factor of 2.5 better. Given how cheap wind is, you can easily overbuild a factor of 2.5 and still be cheaper than new nuclear.
You cannot make those multiplications. When there's no wind, having 2.5x the wind turbines doesn't help at all. In very general terms, adding a 9 to the reliability stats on engineering projects, usually adds an order of magnitude in the cost.
But more importantly, nuclear plants are up WAY over 90% of the time. If they need to do maintenance, they do one reactor at a time in the 4-5 reactor plant. This is similar to how they do maintenance on one turbine at a time in a hydro plant.

Nuclear, wind, solar, they all need storage. Wind and solar because sometimes there is no wind or sun. Nuclear because building out for peak capacity is unaffordable.
But I responded to 'Nuclear uptime is orders of magnitude better than solar or wind'. That is simply not true. Uptime cannot be 10 times better. It could be rephrased as the downtime of nuclear is one order of magnitude smaller than wind. But even that is not clear. And certainly not 'orders of magnitude'.

The "backup" for nuclear is another nuclear plant. It is unlikely that both will go down at once.
This won't work with solar or wind becuase no sun in one location usually means no sun in a much larger area around it. Same for wind.
The sun and wind much further away are of no use because it is not practical to tranmit that electricity to the location it needs to be.
The existing nuclear plants have ceased production once every few years at the worst. In contrast, wind mills and solar panels stop producing electricity multiple times everyday.

Nuclear cannot do peak power in any affordable way. So it doesn't matter how reliable nuclear is, if there is not enough power in late afternoon/early evening then the grid is broken.
Given the current costs for nuclear power, you can do a lot of crazy stuff with wind and solar (like transporting it over long distances) and still be cheaper than nuclear.

This is absolute nonsense. Of course nuclear can power up and down. Who told you it couldn't? The fuel costs of nuclear are a tiny tiny portion of the operating costs, so it's trivially easy to power on/off the reactor.
Also, the long distance transport costs for electricity are massive - can be 30% loss. Look at HydroQuebec. They massively overproduce just to transport over HUGE long distance power towers because of the huge losses - and that's only 500 miles.

https://grid.iamkate.com/ - overly good day for renewable production in the UK, my thoughts:
1. Wind is really cost effective for the UK and loads more is due to come online
2. EPR reactors keep running massively over budget e.g. Flamanville 3
3. Research money is heading into the best ways to store grid level energy.
All in all I am very hopeful and not against Nuclear at all but I just can't ignore the charts today.
Such a nice thought that a good % of my flat is being powered with little consequence!

Oh it's windy today? Great! I guess it'll be windy every day in the future, let's replace all energy production with wind farms! /s

Yeah, but that’s in your head.
I have friends with the same dilutions.
"We just need to build loads of tiny mechanical generators and enough batteries to store a few days worth of our countries electricity consumption"
How someone can say this (and still claim to be green) is beyond me.

The problem is that for much of the current generation of politicians in power, particularly in Germany, all thought about nuclear power has been frozen in time since 1985.
Furthermore you have bought-and-paid-for members of the establishment like Gerhard Schröder who have a vested interest in shutting down nuclear power plants.

I'm from Sweden, and we've also been shutting down reactors, but Germany is the biggest offender in Europe on this particular issue, I hope Germans are raising hell about this at home just like I try to over here.
Sweden is planning for super energy intensive green steel, the Northvolt battery production and recycling facility, huge datacenters for Microsoft/Google/Amazon/Facebook, and on top of that a rapidly accelerating electrification of private vehicles. To cover this they are planning to expand hydro, but the estimates I've seen are for an additional 600MW which is literally nothing in context (green steel alone is estimated to need 9000MW) and will do fuck all for the new requirements from the above, it's fucking looney tunes.
I personally think the environmentally best short-term solution would be for all the shut down but technically still usable reactors, in countries like Sweden and Germany, to be turned back on while we construct new safer and more future proof ones.
I should buy a UPS.

The German reactors have been run in maintenance mode. They cannot be switched on again
We could've partially solved the problem with steady construction of wind farms which were politically held back in the last 10 years.
Wind generally can't provide base load due to its sporadic nature. They really aren't substitutes until we get cheap energy storage
This. We need nuclear to keep the base load green. Wind and solar need batteries to be base load providers. Building out both battery and renewable infrastructure at the same time is a tall order.
Yeah this is what most people are not getting in this whole debate. That and the fact that it's really costly to transmit electricity over long distances, even at extremely high voltages.
The best solution is a bunch of smallish nuclear reactors spread out over the continent for base power production, wind/solar/hydro (is wave electricity a thing? I remember it was discussed a bunch of years ago in relation to green production) wherever those make sense, and high voltage transmission lines to allow load balancing.
But we don't have that, and it takes a long time to build so we should get started now, but instead they will say "oh we should have built that 20 years ago now it's too late"... :(

The surprising thing is that with a rare exceptions (like in Finland) people who have money to invest don't believe that investing in nuclear power will actually make them a profit.
We know the price of CO2 will just go up and up. We know how hard it is to create a base load with wind/solar and storage.
Yet nobody with money believes it is worth investing in nuclear.
Of course, looking at Hinkley Point C, Olkiluoto, Flamanville makes it very clear why nobody wants to invest in nuclear power.

I think the biggest reason is public opinion (by idiots who don't know what they are talking about and just think nuclear bad because they've been conditioned to think so by decades of misinformation) driving politics in the wrong directions possibly meaning that any plants built may be forced to shut down before they've been operational long enough to offset the construction costs and become profitable.
There are no blackouts in Europe. There's no energy shortage. This is not Texas. There's a cost problem, however. With gas specifically. And that reflects in the electricity prices currently because there are quite a few gas plants.
Until recently, nuclear was the undisputed king of cost. There was nothing more expensive in the market. And that's before you count the cost of long term storage, security, and decades of government subsidies. I guess, for this year it might look quite alright compared to gas. But that is probably a temporary effect before it goes back to its undisputed status as being the most costly thing in the market.
Replacing an expensive thing with an even more expensive thing is not a solution to reducing cost. It doesn't make sense. Europe needs cheap power, not expensive power. And it's getting plenty of that from renewables. It's far ahead of most other places in the world in terms of deploying wind and other renewables.
The nuclear phase down in Germany is actually happening without any disruptions to energy supply. The grid seems plenty resilient (again, rolling blackouts are not a thing here). Also, there's a healthy growth of other capacity and it's a very competitive market with lots of innovative companies making lots of money.
Nuclear was always a relatively minor part of the energy economy in Germany. We're talking about some 20GW of capacity in total of which some 8(?) GW remains which is on track to disappear later this year. Compared to the new capacity that has been added in (mainly) wind and solar form since the nuclear phase out started 12 years ago that is nothing. About 3x the amount of nuclear capacity Germany ever had was added in wind energy alone since then. Probably in the next few years more will come online than Germany ever had in nuclear capacity. People probably have more solar on their roofs than ever existed in nuclear capacity. That was growing at a pace of almost 0.5GW per month last summer apparently.
The reasons electricity prices are high is because the EU is overly dependent on natural gas, which until recently was vastly cheaper than nuclear (and coal plants). The current geo-political situation with particularly Russia is disrupting oil and gas prices. Not because there is a shortage but because Russia is trying to pressurize the EU to do what it wants. The cheapest solution to that is diplomacy. And given that apparently gas prices dropped 11% or so after Russia kindly started providing gas through Ukranian pipelines again, that seems to be working.
The likely long term effect will be an acceleration of replacing gas with other things. That was already happening anyway. Higher prices will make it happen faster.

I'm still waiting for a practical alternative to natural gas for small housing units (apartments, or just small houses without gardens). Heating water with heat pumps is impractical unless you have a lot of space. My combined hot water/central heating heater is the size of a large microwave oven. If I can replace it with something similarly sized, I will. Until that's possible, I'm afraid I'm stuck with gas.

You don't do centrally heated water in apartments over there? I don't think I've seen anything else here in Sweden. We actually buy heated water from the grid in my housing cooperative, but a lot of them have "downhole heat exchangers"* installed and produce their own centrally heated water circuit, which is also common for villas over here.
*: called bergvärme in Swedish, I just looked up the Swedish wikipedia article and clicked English so I don't know if this is the right term

In The Netherlands, more than 90% of all homes is heated using natural gas.
Part of that is historical, but also cooking on natural gas was for a long time the best solution. So if you run natural gas to every home anyhow, there is little reason to have a separate hot water distribution system.

We don't, no. Some older (and often very large) buildings here in Belgium do, but most apartments have individual gas heaters.
Some very new constructions rely on district heating, but that's only feasible if there's a source of waste heat nearby (some kind of factory, usually). I doubt we have more than 50 such constructions in the entire country.

Of course, in Germany most houses have central heating and central hot water production in a room in the basement. A lot of them even have large oil tanks which could be removed for additional space.
There are a few old Buildings from the 50ies, which still have gas heating in the appartments, but they are relatively rare.
Shortage and Cost are 2 sides of the same coin.
In a dynamic capitalist economy you will only have Cost issues.
In a mixed or socialistic economy you will have shortages due to rationing.

... yet (and that's only for large-area outages. In 2019, large parts of Berlin were without power for over 30 hours [1]). Wherever I look, civil protection agencies are scurrying to set up contingency plans for a multinational, month-long blackout. In Switzerland, the public broadcaster has started communicating that risk to their population three years ago, clearly stating that this will lead to a massive loss of lives. We are running into a catastrophe, and we're too ideologically blinded to accept it.
Better stock up on those conserves and gas cartouches for cooking.

Yes, if you run it over with an excavator, even a German power line will break :p That is what happened in the link you posted. So it has nothing to do with the energy production capacity in Germany. And there is little to fear in this respect. There is still a healthy amount of reserve power available.
I actually live in Berlin. I don't remember ever being without power for more than minutes in the 13 years I've lived here and all of those were basically things like blown fuses and had absolutely nothing to do with capacity shortages. This power outage was in a specific area (Köpenick) in Berlin that only affected a very small portion of the Berlin population (30000 people on close to 4M people in Berlin). The root cause was some infrastructure work resulting in a power cable being cut. That stuff can happen anywhere and it had nothing to do with a capacity problem. There was plenty of power but they were cut off from it.

On a relevant note first plasma in ITER is still 3 years out.
https://www.iter.org/construction/construction
And it won't use tritium until 2035 or later. And it will never be able to breed tritium, or operate on DT for more than a few weeks total. And it's on a technological dead end to anything that could be competitive, even with fission.
I am not any kind of expert in the matter, but I don't buy the technological dead end argument.
But still if everything worked perfectly I would hazard we would still be at least 20-30 years out of a commercial project that would cost billions and take a decade to build.

There has never been any plan for ITER to produce electricity. Instead, all powered produced is going to be vented into the atmosphere.
The scientific work that is planned to be done at ITER has the possibility of proving that nuclear fusion may be a viable path for electrical generation. But it will never serve as a commercial basis for the generation of electricity. Accomplishing nuclear fusion is actually relatively easy. What it hopes to prove is that controlled nuclear fusion can serve as a net producer of energy. A complete success of the ITER project in no way implies that nuclear energy is commercially viable. From a scientific standpoint it is amazing work. From an energy generation standpoint, it's a card trick.
The follow on "DEMO" project will attempt to establish commercial viability of nuclear fusion for electrical generation would commence operation no earlier than 2050.
If clean energy is something we need now, then nuclear fusion is not a viable solution.

That was kind of my point as well, commercial fusion is decades out in the best of cases, thus making the reluctance to maintain and or invest in proven fission technology that much more risky. If commercial fusion was few years out I would be much more sympathetic to objections to fission.

That you don't buy it doesn't mean it's not true.
ITER has horrific power density, some 400x worse than the reactor vessel in a fission power plant. Given that the non-nuclear part of the a fission and DT fusion plant will be similar, making the reactor itself much larger and much more complex, and therefore much more expensive, cannot be a win. The less experimental follow-ons to ITER (PROTO, DEMO) are still massively too large.
This generic problem with DT fusion reactors has been known since at least the 1980s.

The UK's STEP project uses a higher aspect ratio ('spherical tokamak') to reduce the required size of the machine.
The initial investigations from MAST are encouraging, but we'll see how it goes.
Of course, this stuff will be ready for commercial use in like 2050 assuming everything goes to plan (which is rare unless it's really prioritised like the Manhattan Project, Apollo Missions etc.)
So regardless, something will have to be done prior to then - either we find better energy storage solutions for renewables or we expedite the construction of replacement/new fission plants or both.

Whenever you see happy optimistic talk about a DT fusion reactor, ask them "what's the power density of your reactor?" And make sure they're using the volume of the reactor itself, not just the plasma.
For a PWR, this is about 20 MW/m^3 . For ITER, it's 0.05 MW/m^3 and for ARC (2014 paper) it's around 0.5 MW/m^3 .

There is a chance that it won't be commercially viable. See e.g.: https://www.youtube.com/watch?v=V_0VEmN7Bg8
I was under the impression ITER was a research and development project, not intended to be commercially viable, but essentially prove the technology as working.
This is a key point:
> Plants, though, take a decade or more to construct at best and the risk is high of running over time and over budget. Finland’s new Olkiluoto-3 unit is coming on line after a 12-year delay and billions of euros in financial overruns.
I'll expand on this further: do you know how many of the world's nuclear power plants (~660 IIRC) were privately funded and built without (significant) government subsidies? The answer is zero. This is not just a construction issue, it also affects maintenance [1].
Sure lets continue researching smaller, modular reactors that can be constructed more cheaply and in less time. But we're not there yet. None of the research projects, prototypes or proposals are anywhere close to commercial viability yet. Most of them don't even exist yet.
Personally I'm bearing on fission power. Plants take too long to build. They're too expensive to build and maintain. I don't trust humans or corporations for long-term management and maintenance, particularly in countries without strong government. We don't have a good story for the long term storage or disposal of enrichment waste or power production waste. The significant systems required around mining, fuel processing, spent fuel processing, maintenance, fuel replacement, inspection and oversight (eg the NRC) are significant and won't scale to the required level.
The article is right though: this is political and the politics are bad for nuclear. It will take the likes of China to mass deploy nuclear once these problems are solved to change any opinions in the West.

Your source does not say anything about gov't subsidies for nuclear plant construction.
Nuclear plants are built, like any power plant or major project, with corporate/state/municipal bonds. These aren't really handouts. They are fixed income instruments that allow corporations to spread the cost of construction over the life of the project.
Nuclear reactors are profitable. The challenges are those we create to stop them. Lawsuits, protests, political work stoppages, etc...

A lot of assumptions wrapped up in that short headline.
"Europe is losing ICE vehicles, just as it needs to transport people."
"Europe is losing ICE vehicles, just as it needs to transport people."
Except ICE vehicles are not providing a unique firm low carbon capability like nuclear is.
Nuclear is obviously key to energy independence etc... but the very common take these days of "Nuclear power is the safest energy production technology available, just look at historical data" is deeply misguided.
It's very hard to accurately estimate the risk of a nuclear power-plant disaster because looking back at the past and extrapolating data from there is non-sensical when the risk is so fat-tailed. Sure, Chernobyl, Fukushima and ever Three Mile Island killed a few thousands at most in aggregate but for anyone familiar with the history of Chernobyl, the story is quite different.
10 days after the main explosion, a leak caused a large amount of water to accumulate under the melting core. Had the melting core reached that pool of water, it would have caused a massive steam explosion that would have spread radioactive particles over most of Europe and Russia making them uninhabitable. Thankfully, three men risked their lives to enter the power-plant and closed a valve preventing more water from accumulating under the core.
Now, you could say that current reactors are safer, which might be true, but before Chernobyl, such a disaster was also thought to be impossible. Even if there is a 10% risk of contamination of a whole continent over a century, does it make sense to take it? One could argue that such risk would be acceptable if it prevents climate change. But acknowledging the existence of these enormous risks is a required step to have an honest debate.

Sure, Chernobyl, Fukushima and ever Three Mile Island killed a few thousands at most in aggregate but for anyone familiar with the history of Chernobyl, the story is quite different.
10 days after the main explosion, a leak caused a large amount of water to accumulate under the melting core. Had the melting core reached that pool of water, it would have caused a massive steam explosion that would have spread radioactive particles over most of Europe and Russia making them uninhabitable. Thankfully, three men risked their lives to enter the power-plant and closed a valve preventing more water from accumulating under the core.
Now, you could say that current reactors are safer, which might be true, but before Chernobyl, such a disaster was also thought to be impossible. Even if there is a 10% risk of contamination of a whole continent over a century, does it make sense to take it? One could argue that such risk would be acceptable if it prevents climate change. But acknowledging the existence of these enormous risks is a required step to have an honest debate.
> spread radioactive particles over most of Europe and Russia making them uninhabitable
JFC, this is the perfect capture of the level of debate surrounding nuclear
If it was true, don't you think every single country in the world would obtain such a world-destroying weapon?
If it was true, then a single nuclear reactor would be able to power the whole world for eternity

Countries already have nuclear weapons. They can very well spread radioactive material over large landmasses but what's the point?

I have no idea how you deduced this but it's wrong.

You got any proof on that "end life in Europe and Russia" claim? Because I've certainly heard it could have been a lot bigger, but wipe out Europe and a big portion of Asia? I have a hard time believing that.
It wouldn't wipe out Europe but make uninhabitable due to nuclear fallout. Same as the exclusion zone near Pripyat. https://historyofyesterday.com/the-real-life-suicide-squad-w...
> As the Fukushima disaster unfolded in Japan in 2011, then-German Chancellor Angela Merkel made a dramatic decision that delighted her country’s anti-nuclear movement: all reactors would be ditched. What couldn’t have been predicted was that Europe would find itself mired in one of the worst energy crises in its history
That's just not really true, plenty of people warned that with Germany closing nuclear and coal plants at the same time it would need to rely on external sources for energy, France for electricity, and with NordStream 1 and 2 projects, the reliance on Russian gas for Germany rose to around 50%. It was pretty obvious that becoming dependent on a not always friendly foreign power was a bad idea, but with Germany being so dominant in Europe no one dared to oppose it. Now Russia is playing this card fully.

I think ramping up usage of gas is a bad policy. Even taking a little bit longer, but jumping from coal to renewables make more sense than using gas as bridge fuel.
We should either go nuclear or renewables with storage. There are still some good spots for hydro-storage as well as batteries are getting cheaper each year.

Nucler power is just too risky of an investment. You can set up a solar park in weeks, nothing compared to the decades of lobbying, nimby-backlash, getting the planning permissions, financial
risks and pouring billions into the nuclear plant. And you still need massive tax cuts and securities from the tax payers for it to be profitable, not to mention the government to help you out if the darn thing goes pop. A d Murphy know a nuclear power plant is one of the most complex machines we humans can built.
Why would you do that as an energy company. Ask Tepco if they are happy. They aren't. The only countries that still build nuclear are the ones that massively promote it for political reasons and it's often countries with an or wanting to have an arsenal of atomic weapons, go figure. Nuclear is a dead horse unless.

Nuclear costs so much because we haven't built reactors in decades. If we had been focused on nuclear innovation and deployment consistently since the 50s, then (a) we would have smaller nuclear facilities by now that are much easier to deploy and can't melt down and (b) operationalizing and deploying nuclear in general would be much cheaper.
You have a headwind to doing an activity when you rarely engage in an activity.
Chernobyl really messed us up in this regard, sadly.

How about 3 mile island or Fukushima or countless other times where we got lucky. Nuclear disasters are an inevitability with such a complex technology. I'm all in favour of more research into MSRs, but it could easily not work out to be efficient enough to scale. And solar/wind/storage/smart grid solutions are already here and demonstrably up to the job.
While the building of nuclear plants indeed takes decades. I would like to point out that the US navy has taken delivery of 22 nuclear power-plants in the last 20 years for the Virginia class submarines[1] alone.
If there was a real push for nuclear energy there would be a way to build a plant a year.

Also each one of these submarines costs 2.8 billion dollars. Given the complexity of the submarines and the cost of other navy assets (1.8 billion for an Arleigh Burke destroyer), I think it would be safe to assume the cost of the reactor is under a billion dollars.
Those billion dollar reactors can't power a city though. Maybe a small town of a couple or three hundred people? For a billion dollars? ehhhhhhh
Incredible you get downvoted for this. You are absolutely correct; nuclear is disappearing because it is too costly and basically only makes sense if you want weapons.
Look at the projects in the UK - delays for decades and massive budget overruns. Or Turkey if you to see something that is driven by dubious reasons ...

Something as paramount to daily life shouldn't be treated as an investment. Yes, it has significant upfront costs, but it generates energy for many decades ( there are literally reactors built in the 1950s still operating) and can't work in a "free market private capital" mode, but why should it? Railways, highways, dams, etc. don't. People need reliable energy. Everyone needs climate change to be reduced, mostly through CO2 emissions. Nuclear solves both of those for a very long time, stably and predictably. No other power generation method can do this at scale while being deployable almost everywhere ( geothermal and hydro are pretty great but don't work everywhere).
Well, in the end someone has to pay the costs and that is the tax payer. That is why amongst the choices for energy production, the overall cheapest is the most popular. The state can help boost a new technology with subsidies, but in the long term, technologies have to be cost-effective. And nuclear power plants have a very bad track record on this, especially recent projects.
The navy is not really a good comparison. First of all, they have large budgets and somewhat different risk tolerances than civil engineering. Powering submarines by solar power is also not a reasonable concept :p But Germany has some fuel-cell driven submarines, which get many benefits of nuclear ones, but of course with much shorter deployment times (max. 30 days).

Not just a risky investment. The downside risk is too large to be insurable. Which is another form of privatized profit and socialized risk.
the only time you ever see these facts creeping out into the light of day is when politicians are attacking Iran for wanting to develop its nuclear programme. They all know that Iran's programme only makes sense to make nukes and they do occasionally hint at it.
Honestly, the battle Nuclear vs Renewable is quite sad when we look at the sources of energy over time.

Yeah they're just pushing it mostly on poorer countries to bear the brunt of coal burning so they can keep their air clean.

Current situtation: The energy sector (in Germany) was never eager to use nuclear fission power, they were pushed into it by politics in last century. The environmentalist movement is weird - in Germany. People want wind turbines but they don't want wind turbines in reach of 2 kilometer. What is stupid, because it is a minor thing compared to nuclear power plants, coal power plants or whatever harm a wind turbine can do (collapsing, hitting a bird...). One example of how people can completely lose their mind are the "Startbahngegener" in the late eighties, shot a cop to dead. Because? They were against a new runway at one of the biggest, busiest and oldest airports in Europe. The runway is not an issue and made sense. We need to handle climate change anyway, whatever we do. Nuclear fission power plant? If it blows up you, your country, your kids, the neighbor countries and everyone else is fucked. We increase the chance with every nuclear fission power plant further. It is not a matter of "if", it is a matter of "when".
Outlook: At least in Germany. Built wind power plants, build more, store energy as hydrogen (whatever the energy loss is, it is better than not to store) and if possible use NUCLEAR FUSION. Yes Nuclear FUSION! It is much saver, creates only a minimum of nuclear waste after shutdown and in case of control loss and blowup the damage is probably on minor level. Wendelstein[2] - an experimental nuclear fusion project which shall test only but not create energy - is doing progress. Interestingly, this works without the usual international affairs which require involving some companies from every country. But we invest to less. There is no guarantee in success, but nuclear fusion is on any level better than nuclear fission. Sadly politics in cold war were no interested in fusion - nuclear fission was easier to develop and usable for weapons.

So what is the current state of affairs with nuclear on CO2 neutrality? Last I heard, in its life time it is not CO2 neutral due to mining and storing the fuel. Are these solved problems?
By that standard, no energy source is carbon neutral since wind and solar also require mining and construction.
To our best estimate, the footprint of nuclear is a bit higher than solar and wind, but much closer to them than fossil fuels.
e.g.: https://www.carbonbrief.org/solar-wind-nuclear-amazingly-low...
Edit: see page 539 here for a better comparison https://www.ipcc.ch/site/assets/uploads/2018/02/ipcc_wg3_ar5...

Almost nothing human technology does is "CO2 Neutral".
The question isn't CO2 neutrality, but "How much worse is the alternative". And when the alternative is to burn Coal, Oil and Gas, Nuclear power wins by a landslide.
Secondly:
Fossil Fuels have to be mined, transported and stored as well. The components of Wind and Solar energy farms have to be constructed from resources which have to be mined and processed. Power plants, be they coal, nuclear, solar, whatever, need to be constructed and maintained.

It's negligable at current levels, but at some point in the next 40 years we will start to run short of easily mineable uranium.
Some of the other ways we might have to mine uranium then are carbon intensive. But research is being done. So it depends.

It really is all relative, it can essentially be carbon negative in a sense if you use coal as a baseline for damage and ability to reverse global warming.
Consider this: Hambacher Forst and return to brown coal in Germany is a direct effect of moving away from nuclear. That would be a great background to the total CO2 math.
If democratic countries build more nuclear power plants, then won't that encourage less democratic countries to also build nuclear power plants, and then eventually nuclear weapons?
"We're not making nuclear weapons, only nuclear power plants" is what countries like Iran say. And many other countries would like them to stop.
I'm not agreeing or disagreeing, just giving a wider perspective.

Let's get real, nuclear is a solution in search of a problem.
It's low carbon, but we've decided not to cut our emissions, so why bother?
It would rescue us from Russian gas reliance. But cost 10 times more and won't be ready till 2040 so why bother? (Plus you can't replace domestic gas supplies with electricity...).
It's reliable for base load, but we already have that from gas so why bother?

What? Where do you have this from?
What? Where do you have this from?
We've increased our emissions almost every year for decades.
A few years back, in Paris, we signed a "you do you" agreement to all decide for ourselves whether to cut our emissions and not to complain if others don't cut them.
We're well on schedule to blow through all the ppm concentrations (I think we blew through the 1C rise one last year some time?)
It's like this weird open secret where we all agree something should definitely be done, and then do nothing. Like 100 people are a car crash all hoping someone else will get involved or something.

Not just nuclear, the Netherlands is stopping all it's gas production.
Europe is a very diverse continent. Something that tends to be forgotten in American perception. A country like the Netherlands has practically unlimited amount of money to import oil and gas from abroad while people in Greece are reduced to burning wood to keep warm in winter.

Oh great a discussion about international ethics, sure let's dive into the narrative and choose teams. Or not. Anyway, my understanding of the big picture using the mental framework I got from a previous HN post of short and long con(thanks HN)
The short con: Environmental ethics, the other team is illogical.
The long con(Nuclear Lobby): Those that support nuclear have invested and given subsidies to their respective industries disregarding the fact that it is not that safe. The definition of safety is based on the insurance which if I recall was capped at 100mil and the rest is insured by peoples taxes if something happens. If it wasn't capped the concept of nuclear would not be feasible.
The long con(Non nuclear Lobby aka Germany): The previous German counselor (whose politics as I see them from afar where mostly based on human sentiment except when against industry) overshot anyone's assumption of the feasibility of a non nuclear policy and subsidized heavily non nuclear. Then they tried to support by European Lobbying and legislation. The whole thing backfired and they need to buy energy from abroad which has caused a steep increase in prices and a passive policy against Russia. So natural gas needs to also be defined as "kind of environmental" or Germany has no real policy. If it works, and since they are the entry of natural gas for Europe, they can friction everybody towards any policy that makes sense in the future.
Also: The environment something something (I have phased out, EU or any large country does not plan based on ethics, just based on short term reelection goals).
Also 2: EU refused to pre agree with Russians for natural gas prices and the gas price skyrocketed forcing more environmental policy that smaller countries in EU must adopt early. French threw a wrench in German's works who are exposed to their non nuclear investments. Also somehow Russians fault? Sure...
Also 3: Two actual targets of environmental policy: Reduce gas emissions, Reduce nuclear meltdown danger. Pick and choose depending on which country's media you are exposed to and their respective owners financing.
Also 4: 30% increase in non service production due to covid did not help prices I assume.
Guess: They will find an understanding somewhere in the middle, they are financially exposed, which means politically exposed and no one will remember after the a new round of articles from the media. In the meantime we are paying for no reason.

Why are you even here if you don't want to discuss/debate? There are literally a hundred other articles on here _today_ you could go read and comment on.
Building thousands nuclear plants for every country wouldn't suffice if most of their energy is wasted to mine cryptocurrencies -> make money -> build more mining farms that require more power -> more power plants -> more money, etc. It should be clear now that this endless loop is not going to scale and energy prices are going to soar no matter how many nuclear plants we build, because all available one will be used anyway by people who could still sustain higher energy prices.
The problem is not the lack of energy. Actually we'd have plenty if someone didn't waste most of it for just one damn thing that produces nothing of real value in return while slowly killing the planet.
Is this not a little hyperbole? Bitcoin is estimated to use the power of a “small country”. Much of mining happens in China. Surely that is not a primary factor in energy usage right now. It’s still not a sustainable tech IMO, but is that really “the problem”?
> Much of mining happens in China.

Crypto mining needs cheap energy, and household and nuclear electricity is anything but.
If anything, it helps suppliers monetize the load which would otherwise be wasted, like unexpected peaks in solar or wind production.
IF it happened that crypto mining drives electricity prices up, the economy would reach a new balance with mining included.
In any case, crypto mining pays carbon tax as any other industry. If I get sound money in exchange, I agree to pay the transaction fees, which will in turn offset those expenses.

There are cryptocurrencies that do not need more power than any other kind of computing because they do not rely on proof-of-work. Proof of work is a waste at any price. Better to use low cost renewable power for synfuels for aviation or other high value applications.
One point of proof-of-work is to allow chain continuity in the event of a network split.
You can easily tell which chain has the most work sacrificed, but if a netsplit occurs with a proof-of-stake protocol, it is vulnerable to a Sybil attack hijacking consensus with, say, a botnet.

Try "build nuclear powerplants to meet demand" - Bitcoin stops mining as much as. Ethereum switches to proof of stake. Other coins switch from proof of work too. Crypto energy demands drop. We are left with a bunch of powerplants hanging out providing surplus / super cheap power. Humanity levelled up, whoo.
> if most of their energy is wasted to mine cryptocurrencies
This is not ahppening at all, so not sure why you mention completely absurd scenarios.

Crypto uses less than 1% or something. What are you talking about?
If anything, it's the upcoming mass transition to EVs that worries me, suddenly the 80-year-old grandma from some village in the Carpathians will have to compete on the same deregulated energy/power market against a fancy lawyer from Luxembourg who drives his 150-170k Tesla or Porsche.
It has a pathetic amount of transactions.
If it's adopted to any extent it will need a lot more than that.
If it's adopted to any extent it will need a lot more than that.
As the inflationary BTC miner reward halves every 4 years, the miner income will gradually shift to primarily transaction-fee-based. I suspect this will drive down the available energy budget.
Imagine this dismall planet dotted with decrepit nuclear plants, even as the societies that are supposed to keep them safe collapse either of their own accord, or due to interminable warfare.
When deciding on the wisdom of adopting a technology that will shape our fate for the next century you don't condition on the best (or even expected) scenario, you condition on the worst plausible scenario.
For a long as we haven't solved our obvious and serious socio-economic pathologies it is actually safer to keep burning carbon. At least that damage is in-principle reversible.

Sounds like a business opportunity for France to start prepping for the demand for nuclear in a few years when people are paying 1 euro per kwHr
[deleted]
Germany spent something like a trillion euro on renewables and still produces much more CO2 per capita per year than France who spent 200 billion on nuclear (and whose nuclear industry is forced to bail out competitors now)
One would think "green" movements (greenpeace, and modern green parties) have been infiltrated by coal/oil/gas lobbies as so far the only winner out of no nuclear yes wind policy is Vladimir Putin and not the environment

Past spending are actually not relevant, as renewable got significantly cheaper, while nuclear got more expensive.
Solar is today 5x less expensive than it was in 2010[1].

And a large part of why it's cheaper is because Germany spent so much, driving the costs down the production learning curve. The whole world, including Germany, will benefit tremendously from that spending.
I am perplex. Solar energy for example don't take into account the cost of renewal of the panel (every 20-30 year) and the cost of recycling / storing the toxic photovoltaic liquid [1]. The IRENA projects[2] they can fully recycle this toxic waste and recreate value from it, which is bold imo.

Much of the reason nuclear got more expensive is that there's been such a big dip in construction. Lessons are having to be relearned and we're paying for it. That and so many politicians and contractors getting away with being leeches whilst dragging out projects in some countries. Comparisons of construction projects of the same design in china vs europe would make one cry.
Also much of the price reduction for renewables are in things like solar which has other issues like it's shorter lifespan paired with it's recycling being basically a joke/scam.
Additionally if you throw a solar panel or windmill in the trash before it's proper and well done the cost of it's energy in the calculation goes up just the same.

Solar recycling is still rudimentary because the vast majority of PV modules that have ever been produced are still in use. The doubling time of the exponential growth of solar has been much less than the lifespan of PV modules.
The shorter lifespan of PV is actually a good thing for solar. In an environment where technology is changing rapidly, long lifespan has little value. Would you think it's a huge negative if your PC fails after 20 years instead of 40? No, because you replace it before then anyway. Pretending that nuclear is better because its value is computed based on a 40 year lifespan is just pretending that its competitors will stop improving (otherwise, the nuclear plant won't even make it to 40 years due to operating costs > full cost of renewables.)

The problems with it's recycling are a bit more inherent than that.
>The shorter lifespan of PV is actually a good thing for solar.
It's downright silly to say that PV degrading is good for it. The improvements don't stop because they have to be replaced quicker. More people would adopt it if they lasted longer since the ROI is higher, etc I might replace my pc in less than a decade but I'm not jumping to get on a roof again and invest 10's of thousands of euros.

It's good because it means there's another cost decline for PV that will occur even after the manufacturing cost per watt stops declining: simply make the modules last longer. Nuclear has already shot its wad on that one.
It also means PV is less at risk right now from obsolesence. The shorter the time span needed to justify a PV installation, the less motivation there is to delay and wait for better technology.

Given that it still ends up the best from a cost perspective (solar doesn't come close) if extended marginally i wouldn't say so.
There is one core difference. Those extensions, investments and even proper use need political will given the size and scope of such projects. Those politicianse are subject to stupidity and lobbying. Hell the US bans fuel rod recycling at the behest of oil and gas companies to give one such example.

Coal is free underground which is in the same league as saying that solar is cheep at noon.
That something this simple is never talked about when it comes to renewables is a monument to peoples ability to ignore the obvious.

You've been posting comments that get flagged, then deleting and reposting them many times—in one case, over a dozen times! That's abusive, and we ban accounts that do that sort of thing, so if you'd please stop doing it, we'd appreciate it.
Also, if you could please stop posting flamewar comments in the first place, that would be good, because it's not what this site is for, and it destroys what it is for.

Rain water will always be cheaper than tap water.
From my point of view, it's not about a competition between nuclear and solar/wind/etc.
It's about the choices that led to shutting down nuclear instead of coal, oil and the green-lighting of gas projects.
If we were serious about our co2 predicament the conservation and refurbishment of nuclear capacity would be as high as a priority as taking fossil fuel plants offline.
And then after electricity production related emissions has dropped to virtually zero we could have a great discussion on how to go forward.

Not modern. Greenpeace was founded 50 years ago with an anti-nuclear agenda. They call themselves "green" because a wolf wouldn't dress up as a wolf, but rather a sheep.
Pretty sure they started out being opposed to live nuclear weapons testing. Not sure what there exact position is currently, but calling them wolves seems unfair.
I disagree. Their influence on policy has directly benefitted the fossil fuel industry and worsened the climate crisis. History will remember them for what they are.
Sadly that won't change as long as the red herring "BUT CHERNOBYL BLEW UP!" still works in public opinion.

Qui bono?
We're reaping what we sowed back then: the "brainwashing" of the public that unquestioningly accept that nuclear power is 'bad' and tightly linked to nuclear weapons and death.
Despite the fact that nuclear power stations do not have to produce "weapons grade" plutonium/whatever and, I'll repeat this until I'm blue in the face, has been responsible for smallest number of deaths of any form of energy generation and produce the lowest amount of CO2 (i.e. zero, other than construction). It's entirely likely more people die in a day world wide from fossil fuel pollution and production than have ever died from nuclear accidents.
> The trouble, as ever, is time. “Any investment decisions you make now aren’t going to come to fruition until the 2030s,” said Osbaldstone, the research director at Wood Mackenzie. “Nuclear isn’t an answer to the current energy crisis.”
As the saying goes "the best time to build X was yesterday".
Careful what you wish for. The millions of tons of CO2 we could have avoided emitting in Europe...
> “Nuclear isn’t an answer to the current energy crisis.”
Sorry, but to use an old quote, nuclear is the worst solution to the current energy crisis, apart from all the others.
