This is just like how universities hide their animal research facilities. It wasn't until the final year of my biology degree that I found out we had a basement floor under our life sciences building where this research is carried out.
I visited a few times as part of a research project I was involved in, and that experience was one of the factors that put me off pursuing a career in biomedical research.

If we can’t have a good faith discussion then maybe it is a good idea to hide nuclear and animal labs.
But with less oversight, that also invites abuse.
You can probably imagine abuse on your own in an anima lab, but I would also point out after Obama banned gain of function research in 2014 U.S. scientists moved their lab to China where it continued without the same oversight, and bad things happened.

Joe Public doesn't provide oversight. He's mostly good at generating outrage. Experts provide oversight, and animal research in the US is highly regulated by experts!
People like Erin Brokovitch, Lois Gibbs, and Wilbur Tennant seem to have provided significant oversight that has proven beneficial to society.
As a Joe Public, how do you suggest that I can verify the oversight of experts?
Is there sufficient oversight with animal testing in a place like Wuhan?

Erin Brockovich and Lois Gibbs generated outrage, which was well deserved and a societal good. They were working against unregulated/underregulated firms, which did not have effective oversight.
Oversight for PG&E should have come from the US EPA. I suppose the EPA should have handled Love Canal too, but the agency didn't exist when Hooker dumped their pollutants.
Your cultural references suggest you're American, so you don't have a direct way of interacting with a sovereign nation's internal affairs. You can, however, elect competent politicians who support a competent foreign service.
If you want to verify the work of experts, you need knowledge. You need to read, practice, and talk. Once you develop relevant expertise, you're an expert and no longer Joe Public. There are public universities near you where you can learn any of these topics. If you're in a remarkably remote location, you can take online courses. It takes time, but that's true of almost anything worth doing.
If you aren't willing to do that, you're just proving Asimov right: "There is a cult of ignorance in the United States, and there has always been. The strain of anti-intellectualism has been a constant thread winding its way through our political and cultural life, nurtured by the false notion that democracy means that 'my ignorance is just as good as your knowledge."

This kind of dismissive attitude and condescending tone is a big part of why people don't trust people who say "trust us, you don't need to know what we're doing to those animals in the secret basement at the university."
For the record I am not American and I have sat in on a few institutional review board meetings that pertained to animal welfare relating to a project that I was involved with.

Animal research is regulated, but not by a public jury. "We don't advertise what we do with animals in the basement" is because extremists have attempted to murder animal researchers in recent memory[1]. In the US we have a review process similar to an IRB for animal research: IACUC.
I'm dismissive of and admittedly rather condescending to people who equate their ignorance to experts' knowledge. But that's the whole point: expertise isn't a hereditary title. It comes from study, and I support anyone's effort to gain it!
For what it's worth: if you've sat on an IRB you're not Joe Public. You may not be a scientist, but you're an expert in another field. You also know that, so I don't get what you're arguing.

Do you feel the same way about the livestock industry? Like is that an industry that is sufficiently regulated that the public should not be allowed to have any input on the regulation?
Are there any other industries that don't involve animals that you feel the same way about? Why or why not?

This is a problem when the definition of expert is made by politicians and bureacrats instead of academic rigor
In the dictionary definition that politics is "the total complex of relations between people living in society", academic rigor is defined by academic politics. It is a political problem, which means the definition and fundamental regulation will be made by politicians.
Consider supporting politicians who respect expertise. If you aren't presented with that ballot choice, at least vote against the anti-intellectuals.

As a dyed in the wool leftist I more and more struggle with Obama legacy from common core to regulation to his utter selling out the American people to the cia.
When he was well intentioned he seemed to be a total failure and when he was blatantly self interested he was monstrous.
I don’t think the right is another option but woof… this is tough

He was a corporate democrat. His cabinet was effectively selected by Citigroup. He burned home owners immediately and continued senseless wars. The difference between him and Bush was minimal.
His "legacy" is completely a media creation.
We lost control of this country the day JFK was killed.

It was obvious when he was president that he's a terrible person. Not sure how you're struggling with it now. He's just a guy like anyone else. Not special. We shouldn't deify presidents. I didn't vote for him in 2008 because I thought he was too inexperienced. I didn't vote for him in 2012 because he continued the war of terror.
I didn’t say any of this. I think you are responding to
Your own thoughts and not mine.

You're struggling now but presumably weren't struggling then even though it was obvious at the time that he was a bad person just like the rest of them.

I actually strongly considered voting for McCain.
What bad things?
It's a reference to the theory that perhaps covid came from, and accidentally escaped from, a lab.
Wasn't this theory proven by documents that were released and reported on?
No, it’s very squarely in the conspiracy theory category.
Respectfully, I challenge you to show that it's any more "in the conspiracy theory category" than zoonotic crossover in a wet market.
I don't mean to say that it's proven, because to my knowledge it is not. There is a great deal more evidence pointing to it being likely than necessary for it to be considered a mainstream theory.

You’ve shown that zoonotic origin is a reasonable theory; I do not dispute that.
I’m asking you to show that a reasonable person wouldn’t consider a lab origin, which is what you asserted.

That's not how the burden of proof works. If you are putting forth the lab leak origin, it is you who must provide reasonable evidence in support of it.
I did not put it forth. The other user asserted that it was “conspiracy”. That’s the assertion that I’m challenging, not the veracity of the theory itself.
I’m sorry but no, I consider myself quite rational and I simply didn’t stay up to date on the subject, to me it was still a possible theory with others. When a theory was seriously considered not too long ago you can’t suddenly label it conspiracy.
The idea it came from a mystery animal species that despite six years of intense searching hasn’t been identified is the conspiracy theory.
To be fair an operational animal lab is an order of different ethical problem than safely storying radioactive material.
And the two combined present an enormous ethical challenge but also enormous potential - radioactive spiders imbuing superpowers upon humans they might bite, magical ooze creating anthropomorphic turtles, and so on
Operational radioactive animals!
Could you describe the experience? I’ve always wondered what biomedical research was actually like.
A standard part of preclinical research for medicines and topical ingrediants is to determine the LD50. That is the dose per unit of weight of an animal, typically lab rats, that will kill just about 50% +- some small range. That is time consuming to zero into a 50% kill rate over a statistically significant sample.
I suggest we should strive for a more educated public to raise the percentage of people who can have informed discussions. We've seen what happens when education is watered down, so let's try raising the bar, and pushing more science in high schools.
These public freak outs is also why we don't have abundant nuclear energy.
The climate activists of the 60s-90s stopped us from building more reactors, one of the cleanest sources of energy ever known.

And now that there are a number of barriers to creating new nuclear, the propaganda has flipped with fossil fuel companies supporting nuclear because they know it'll be decades before anything real can happen.
I have nothing against nuclear and if it can be built I'm for it. But at the moment, solar + battery is quick to deploy and about as cheap as you can get.

> But at the moment, solar + battery is quick to deploy and about as cheap as you can get.
The actual equation is solar + battery + gas fired power plant.
That’s the dirty secret behind intermittent power sources and why fossil fuel companies are all investing in solar and wind. Batteries are simply not enough to face the long term intermittence. It’s purely an intra-day solution at the moment and nobody knows how to actually run a large grid on purely intermittent sources.
Even China is actually aggressively pursuing nuclear at the same time it builds an insane amount of solar and gas fired power plants.

The actual actual problem is energy per acre of land per year.
Solar is king in places like west Texas and Nevada. Massive sunny flat sprawling landscapes where the land is practically free.
It's a different story in places like Massachusetts or New York, where land is expensive and the sun is mildly sunny.
Gas becomes much more competitive because you only need 5 acres instead of 500, and the energy is 24/7.

Long distant transmission lines would help with that. Also, I want to point out we need to decarbonize, so I don’t think gas considers all externalities that it causes, like air pollution.
The problem is that people don't really want to pay for it.
When you compare the rates at which people recognize the need to decarbonize, to the rates at which people are willing to pay 20-50% more for green energy, an obvious and expected trend arises.... people overwhelming don't want to put their money where there mouth is. Or they want someone elses money to go where there mouth is.
It needs to be understood that almost all those "green energy is cheaper than fossil fuels" studies use the best case scenario to calculate those values.
To put that another way, gas meets it's ideal pretty much everywhere, whereas green energy meets it's ideal in small, often far from society, spots. Transmission can bridge the gap to a degree, but it's then a cost multiplier.
A carbon tax is a good way to balance this, but man, people vote hard to not have to spend more of their own money. (I don't want to pay for it/I only want it if billionaires pay for it)

If you make the carbon tax revenue neutral, and dividend out the whole take per capita, those below median carbon emissions should end up ahead, and it does end up resting on the wealthy, since carbon emissions generally scale with spending.
"how many acres are in the gas field??" I type into the goose meme generator.
> It's a different story in places like Massachusetts or New York, where land is expensive and the sun is mildly sunny.
Even in those places, the cost of land is a small fraction of the cost of a PV installation.

I don't know about activists, vut the US green party was influenced by russia for years. There is evidence of influence with Jill Stein for instance. But if you pick a political organization anywhere in the world that doesn't show signs of Russian influence, that would almost be more suspicious.
To pretend that the US "green party" has anything to do whatsoever with the environment is beyond naive, it's completely disconnected from reality.
Neither their policies nor their electorate support the idea that people like Jill Stein are in any way looked at as authorities in any "green" subject.
I don't think that someone that had national relevance for roughly half an election cycle, and who got less than half of one percent of the vote (at the peak of her popularity) has had any influence shaping nuclear opinions.
She's not even on record stating her position, that's how utterly unimportant this issue to Putin / Russia.
I'm not even sure how you think Russia would benefit from less nuclear power plants an entire continent away

It's not about any one person. You still see this now, where people suggest regulatory reform for the process of building new nuclear plants in the US to lower construction costs, people appear to tell you that nuclear costs too much and should be abandoned, i.e. they use circular logic to present the existence of the problem you're trying to solve as a reason not to try to address it.
The current line of reasoning is something like "solar plus storage is cheaper than nuclear so nuclear must never be attempted", which ignores both any possibility of improving the cost efficiency of nuclear and that the cost comparison they're using is for intra-day storage whereas nuclear also reduces the need for multi-day storage which is significantly more expensive.
> I'm not even sure how you think Russia would benefit from less nuclear power plants an entire continent away
Russia is a petroleum exporting country and petroleum is a global commodity. If the US (or anyone else) uses nuclear instead of fossil fuels then global demand for fossil fuels declines, US natural gas or coal producers instead sell to foreign customers who might have bought gas from Russia, etc.
Notice that the US oil industry has the same incentive. Exxon is very much aligned with Putin on this one and they have lobbyists too.

one of the current approaches is to turn communities against solar and wind projects on the grounds that it's racist or disturbs plant life etc. This has advocates of environmental justice, which is an important concern on its own, weaponized against building renewable energy.
Here's one example in Florida, but it is happening around the US https://www.eenews.net/articles/fla-solar-plans-stoke-fight-...
The net effect is a win for the fossil fuel industry and a weakened environmental movement.

NIMBY homeowners mostly. For instance, these days the Sierra Club mostly exists to preserve property values by blocking all new green energy construction.
IDK, Maybe china? China is eating everyone's lunch when it comes to producing green tech (particularly solar and batteries).
China is eating everyone’s lunch on new(ish) sources of energy because it seems to have basically run out of old(er) ones. The insane amount of coal burning aside, there are e.g. basically as many hydroelectric plants in China as its enormous rivers can support, accompanied by the huge amounts of ecological and societal destruction that those always cause, and that’s still not enough. The buildup of both solar and nuclear energy infrastructure is not motivated by compassion for the environment or (pace George Carlin) the humans that have to live in it, it’s motivated by the cold, hard necessity of powering the industrial base. And if the project can partly fund itself by selling some of the production capacity to others, all the better.
None of this detracts from the quality of the engineering, but it’s important to keep the motivation in view (whether to filter out the propaganda or to try and reproduce something like this at home).

I don’t really care what the motivation is. If it means we get green energy over more coal-fired plants/fossil fuel sources than whatever. Call it Super Awesome MEGA PATRIOT Fuel for all I care.

> solar + battery is quick to deploy and about as cheap as you can get
Solar production is seasonal, batteries to carry over seasons are beyond expensive.
Otherwise 10x your dinner solar to get winter solar and now it's not cheap.

Ok but what about when it’s night time or cloudy?
Solar + battery + wind actually do pretty well. There's a bit of a de-correlation between solar and wind that makes the mix more resilient than either alone. We can't do 100% in most places yet, but it's pretty straightforward to move to a much higher percentage of them in our grid mix than we have now, California possibly excepting. (But even in California you see battery starting to extend how much we can do with solar as prices continue to drop.)
And the plummeting price of solar modules makes it more cost effective to over provision for the case of clouds, and/or to mount solar panels to optimize for morning and evening production as well.

California has energy costs more than double most other states so it’s probably not the best argument for “it’s so easy to go mostly renewable.” A lot of things are feasible if you’re willing to [force everyone in the state to] spend 2x. Whatever California is trying to do in the past 20 years has been extraordinarily regressive.
It hasn’t, it is actually showing the way forward for a more dynamic energy mix. Regressive is continuing with the same 150y fossil fuel receipt for energy despite continuous advances in various clean technologies. California has multiple natural issues with regular fires and dry air that makes energy management very expensive.
Our energy costs are due to the distribution network and the massive amount of deferred maintenance on it that has come due in the last decade, accelerated by the Camp fire court case. There was a two year period a few years ago where power went out at least once a week while SDGE replaced every power pole in the rural east county by flying them in on helicopters. That's largely what we're paying for.
As the above poster said.
Generation costs are a small part of most consumers' bills, but particularly in CA.
If you look at the location marginal pricing map from CA ISO: https://www.caiso.com/todays-outlook/prices
You'll see that right now (before solar has really kicked in), The price for the next megawatt hour of generation is $49 -- i.e., under 5c per kWh. That's comparable to the average price in PJM (east coast) at the same time:
https://www.caiso.com/todays-outlook/prices
vs https://pjm.com/
The big problem for California is that cheap generation via solar doesn't move the needle as much on consumer bills because of the transmission and distribution costs. In San Francisco, for example the distribution fee is over $0.20/kWh. That's twice what mine is in Pittsburgh. In contrast, the generation pricing is only about $0.04/kWh more than mine:
https://www.pge.com/tariffs/assets/pdf/tariffbook/ELEC_SCHED...
though this pricing does favor behind the meter generation such as residential solar.

In terms of consumer bills, California is actually among the states with typical spending on such things. Your actual energy bill in California is not that high. There are 14 American states where residential energy bills are higher than California's.
People are always pointing out the marginal volumetric costs of electricity, which is indeed very high. But that is just reflection of the fact that we use so little energy because of our history of efficiency laws and the mild climate, so the fixed charges and taxes that combine into the volumetric price are much higher than in other states. And our extremely large fleet of behind the meter solar panels also contributes to the higher volumetric price of grid electricity. All together, this doesn't tell us much about whether renewables are a good policy or not.

Agreed. The point I'm trying to make is that the breakdown of California's costs shows that it's not actually the generation cost, i.e., whether or not the generation is solar or fossil is not really the thing that's making the difference.
(When you factor in behind the meter, solar is, in fact, probably reducing the average cost to consumers.)
(When you factor in behind the meter, solar is, in fact, probably reducing the average cost to consumers.)
Cost of electricity and cost of energy should be considered in a conversation about renewables vs fossil fuels.
Many of those other states avoid high electricity costs because they are cold states that don't use electricity for heat.

If the homes heated by gas or oil all switched to grid electricity, that would in all likelihood reduce the marginal volumetric price of electricity by amortizing the fixed costs over a larger volume.
Texas and Florida both have a lot of solar as well, with TX likely passing CA on battery storage over the next few years. Those states also have much cheaper energy than CA.
California's energy problems aren't due to the source of their energy.

Molten salt solar power doesn't care. It remains hot.
Advancements in solar also are improving with clouds.
Also, you know, batteries. When someone makes it cost effective to install a device to sell your car battery power on the grid we'll also have a better time managing the grid during spikes... Would be nice if that also did home battery backup in blackouts... 70 kWh would get me through most of the ones I've experienced.

Molten salt solar power plants are completely obsolete. See for ex. Ivanpah being shut down early because the power its generating is too expensive compared to Solar PV: https://www.renewableenergyworld.com/solar/once-an-engineeri...
Molten salt absolutely does care, keeping it molten controls how much power can be withdrawn. It’s a form of thermal battery (and an inefficient one).
If the sun is shining vs not (and if further withdrawal will freeze the salt) absolutely controls power output.

If the entire developed world had followed the same energy usage and nuclearization path as france, we’d be able to accommodate the entire developing world increasing carbon footprint up to the French level within the same overall carbon footprint we have today.
I also really enjoy privatizing profits and let the public deal with the aftermath.
Exactly. It is amazing how certain people really don’t care about others’ money, and above all, health.
The activists of the 60s-90s were witnesses to the nuclear bombing of Japan, domestic nuclear accidents, as well as a nuclear arms race that threatened to wipe out all of humanity. It is unfortunate that we threw the baby out with the bathwater when it came to nuclear power generation, but the people who had issues with nuclear in that era did have good reasons to be afraid.
Were they good reasons or did they just fell victim to their feelings?
Not creating nuclear power plants because you're afraid of some bombs is good reasoning?
What about the millions of deaths to fossil fuels every year? Are they better than the nuclear accidents we had?
I don't think good reasoning is why they felt that nuclear power was bad.

It is. And also because of Chernobyl and Fukushima. But you don't care do you
We’re going to look back and realise that the destruction wrought by global warming was far worse in every way than at Chernobyl.
I don’t know if you quite realize how close to a major climate change event Chernobyl almost became.
That's not supported by physics. Even at the worst - if the other reactor had somehow also melted down, that still wouldn't have caused a major climate change event. It would have been absolutely terrible, regionally, but not globally. Nuclear reactors aren't atomic bombs.
I don’t understand. Plenty of climate change related developments are regional. See: the increasingly devastating hurricanes forming in the Gulf of Mexico. Not every single thing that we attribute to climate change has to span the entire globe.
You might want to elaborate?
Yep. Also, the pro-nuclear techno-utopians of that era promised that nuclear electricity would be too cheap too meter, nuclear-powered cars would be common, and quite a few other things.
If the public doesn't understand complex new thing X, and advocates for X have obviously told them all sorts of lies - yeah. Don't be surprised if the public becomes extremely skeptical about X.

When you read about how incidents and accidents at research and commercial nuclear facilities have been denied, covered up, downplayed and fumbled sometimes for years and years you realize the problem is not nuclear technology but the people who manage it. Nuclear technology may have progressed but our ability to handle it ethically surely hasn't.
Nuclear accidents were common back then. Activists not only had good intentions they had actual accidents occuring with cover-ups. I think you're only seeing the worst parts here. They didn't follow the science as well as they should but they did get dumping sorted and held the industry liable.

Wikipedia has a chart: https://en.wikipedia.org/wiki/Nuclear_and_radiation_accident...
1. Mining and processing are destructive
Uranium mining leaves behind contaminated soil, groundwater problems, tailings, and long-term ecological damage. “Yellow Cake” shows this clearly. These impacts last far longer than any economic benefit.
2. Operation is low-CO₂, but not low-risk Severe accidents are rare, but the consequences are catastrophic when they do occur. Chernobyl and Fukushima are obvious examples. The U.S. history is full of near misses, leaks, hardware failures, and human-factor problems. Calling such a technology “safe” glosses over systemic vulnerability.
3. Waste cannot be neutralised High-level waste remains hazardous for tens of thousands of years. No human institution has ever maintained stable responsibility for anything even close to that timeframe. Most countries still rely on interim storage because final repositories are politically and technically unresolved.
4. Long-term burdens are externalised The benefits (electricity, profits, political narratives) are short-term and local. The harms (contamination, risk, millennia of monitoring) are long-term and imposed on future generations who cannot consent.
5. “Clean” becomes a marketing word In lifecycle terms—mining, fuel fabrication, plant construction, decommissioning, and waste storage—nuclear energy cannot be “clean” in any holistic sense. It is at best low-carbon but high-burden.
This doesn’t mean nobody can argue for nuclear energy, but it does mean that calling it clean is a simplification that hides very real costs and risks

Certain lobbyists like hiding the end-to-end aspects of nuclear and focus mostly on “energy density”, “clean operations” etc, because they take advantage of the fact most people think short term (because, well, it is simpler). It is like the fossil fuel lobbyists that say gas is cheaper but never mention the externalities caused by e.g., the air pollution causing health issues to those living nearby LNG plants, who end up paying for the costs, just not at the moment of operationalization. Of course none of these proponents live near these infrastructures. This is the very same old 60-90’s stories with the tobacco industry saying smoking have health benefits.
Future generations can't consent to anything, even fields of solar panels and mining for battery materials.
Exactly like Asimov wrote about it in the Foundation. Different way, same purpose.
Almost nobody knew or cared about the coming global warming in the 60s-90s.
Ask the Ukrainian how clean Chernobyl is. I hear it became a very touristic place with people dying to get housing there, because the air is so clean.
Same is surprisingly common when weeding books in university libraries. Care is often taken disposing of material, as it can trigger a lot of drama if discovered by the student body.
> The public cannot be trusted to engage in a discussion about anything “nuclear” in good faith.
I agree the fears and subsequent responses are generally not warranted but to call it “bad faith” (by saying not in good faith) is not fair either. Some people are afraid and don’t understand it. We’ve all seen seen the disasters and communities impacted with higher rates of cancer even decades later as a direct result of the Manhattan Project. This stuff can be dangerous so it’s not meritless even if the reactions are wrong and generally uninformed.

Yes, however I suppose it is fuel for conspiracy theories.
Conspiracists and media brainwashed people will react this way no matter what. Doesn’t matter whether it’s secretive or not. It’s not about you or the subject matter but their need to feel important or in possession of some truth THEY don’t want you to know.
I suspect its less about the need to feel special than you imagine.
My take is that these folks can't accept that nobody is actually driving. It terrifies them to realize that we are all aboard a rudderless ship, so they imagine these secret cabals to be able to sleep at night.
Take COVID. There is insufficient proof that it was the result of lab work, but many many people prefer that warm fuzzy thought over acknowledging that mutating is just what viruses do, and always have done. Knowing that we're all one unlucky mutation away from grisly death is just too much for some folks. "It can't happen again, we shutdown that lab!"
To those people it has to be a nice, neat conspiracy. That way someone is in control, and if we just put those few villains in their place everyone will be safe from viruses, economic instabilty, immigrants, and the boogey man forever.

Steam power is no joke if you actually look at the numbers. At this scale, it lets you move energy around and convert it to electricity in fewer steps, with fewer losses, than any other strategy.
Found it kind of depressing that this seems to be the current strategy for fusion as well.
You have this insane device that produces a million degree hot ring of plasma and use it... to boil water...

We are still trying to solve the problem that we can't keep the plasma hot long enough to create fusion energy, so working on exotic conversion schemes is one step too far.
Consider also how complex these reactors already are, it makes sense to use the simplest method that we know works well.
Consider also how complex these reactors already are, it makes sense to use the simplest method that we know works well.
Makes sense, but from a layman perspective it seems like introducing additional complexity and lots of inefficient, high-loss transmission steps.
We start with detached electrons moving at high speeds (plasma). We want detached electrons moving at moderate speeds (electrical current). And yet, the intermediate steps involve everything from heat, steam, large-scale mechanical forces and magnetic induction, just to get back to the electrons?
It feels more like the "pull in a 500MB framework instead of writing the function yourself" kind of simplicity.

I see a lot of people claiming this sort of thing was “common” (JASON at the Royal Naval College London, MIT’s MITR-II, CROCUS at EPL) but there is a huge difference between these things. Kodak’s CFX was a small device the size of a refrigerator; it is a neutron source and not a reactor. CROCUS is a reactor, but also small (100W thermal) and JASON, while larger, is also low power (10 kW.) MITR-II on the other hand is nearly one thousand times larger at 6 MW thermal.
There are only three civilian reactors >1MW in the US: at MIT, UC Davis, and the University of Missouri. You could also count the RINSC MTR, which is owned and operated by the Rhode Island state Atomic Energy Commission but located on the University of Rhode Island campus and collaborates closely with the university. Similarly, there are only two >1MW in Western Europe (TU Delft and TU München.)
If this sort of thing interests you, I can recommend reading about the history of the TRIGA. Freeman Dyson and Edward Teller designed it as a reactor “safe even in the hands of a young graduate student” and the US government sent them around the world as part of Atoms for Peace.

UMass Lowell has a 1MW research reactor as well.
What a neat device. Unlike those extra spicy, dangerous sources that say "drop and run" on them, this thing only runs when you line up the CF-252 with the HEU plates. It has an off switch to stop the cascade. Perfect for lab use.
Cf-252 is no joke though. It has to be carefully handled. It constantly emits neutrons. And those need shielding, something with lots of light atoms like hydrogen - water, PET or other plastics etc.
At the Univ of Maryland College Park in the mid 1980s, a campus of 40k students, it was common knowledge the was a small research reactor in full time operation right on campus. I can't imagine it was the only school to have one.
My school for undergrad had, and still has, a "Nuclear Reactor Laboratory." I'm pretty sure everyone who cared understood what was going on there.
The university got in trouble in the mid nineties for having buried nuclear waste as well as medical waste (cadavers) on a remote part of campus, but apparently that's not enough to put a Nuclear Reactor Laboratory out of business. Or a large university's medical system, of course.

We also have one at NC State, still there AFAIK. I thought it made sense though given our nuclear engineering program.
I looked it up and apparently we've had 3 or 4 different reactors on campus over the years, first one in 1950: https://nrp.ne.ncsu.edu/about/history/
I'd wager that even most NC State students don't know that it's there though.

It wasn't a secret like the article admits later on.
There are no secrets in a legal sense e.g. NDAs. However, there is a culture around private nuclear labs of giving no hint of their existence so that they can hide in plain sight.
The objective is to avoid attention, not to be secret per se, though the effect can be similar.

Here in Toronto, every once in a while, someone has a meltdown (if you'll forgive the expression) when they rediscover that there is a CANDU nuclear fuel manufacturing plant in their dense and quiet suburb.
Now CANDU reactors run on natural uranium. So they're forming metal pellets out of uranium powder. The main risk is direct chemical toxicity from the uranium, not the radiation. But for many people "nuclear fuel" might as well mean hot nuclear waste.
The mystical level of dread it inspires in some is hard to overstate. Just to avoid drama from the neighbours it's understandable they try to keep quiet.

> And aside from a license renewal snafu in 1980, the device made no waves until its existence was shared with the local newspaper—it wasn’t a secret, just unpublicized.
I think "secret nuclear device" and "license renewal" are kind of conceptually incongruous, even if only at a surface level.
The license renewal has nothing to do with anything. It's not related to the incident where its existence was revealed. This is about "secret" vs "unpublicized", not "secret" vs "license renewal".
In this context "secret" implies they didn't tell the government. Merely not publicising an internal project is totally normal and doesn't warrant "secret project!!"
I guess that depends on how hysterically you read the word secret (including projecting hysterics on others using it). But we at work have a lot of secret projects. Basically everything is given a project code name until it’s public and if you work in R&D you are told not to discuss your work on such projects either outside the company with friends or inside the company with people who don’t work in R&D. That is the closest to the definition of secret I can imagine. And it sounds like this nuclear lab was in a similar category.
If someone freaks out about it, it’s because they think you’re abusing normal, run of the mill product development secrecy, whether to develop a product that shouldn’t exist or to hide a practice that is never intended to be public and is just called secret to avoid scrutiny from an interested public (who, in this hypothetical scenario, feel that they have a right to be interested — think research into dangerous pathogens next to an unprotected public aquifer).

Is there a penalty to discussing the secret projects? Like if your manager/director/vp knew you were talking specifics without some authorized, what would happen?
It sounds like there is no penalty to the nuclear labs except, if you blab to the wrong person, it’s going to stir up trouble.
It sounds like there is no penalty to the nuclear labs except, if you blab to the wrong person, it’s going to stir up trouble.
I’ve never heard of anything more happening than being reminded not to do that (pretty much the only time it happens is when someone is talking with product support and lets slip a feature or product they’re working on will solve a complaint about an existing product). I’m sure you’d be fired if it was thought you did it intentionally to spread knowledge of the secret though.
I guess in this case the question comes down (for me) to whether employees at this lab were asked by their managers not to tell friends and acquaintances what they worked on. Even if not with an explicit threat of harm, asking someone not to tell something is pretty much exactly what asking them to keep it a secret means.

yeah but is this internal project one where we kidnap homeless people and torture them in the name of science or is it because we spent $50,000 to make a new logo? Some secret are meant to be kept. Others are meant to be blown wide open. Others... Other just are, and nobody need to know.

I worked at the main Kodak tower in Rochester for a few years in the early 2000s. Mainly as a paid IT intern of sorts to earn some additional money in college.
I often had to go to the basement there to store equipment, get equipment, etc.
The stuff I'd see down there was WILD. TONS of old movie/film paraphernalia in the form of posters, plaques with celluloid celebrating various movie releases, and tons of unmarked old film canisters. There was also a TON of old tech down there.
I used to joke that I felt like I was in that Hanger 51 warehouse from the end of Indiana Jones and The Ark of the Covenant.
It's a shame things went down as they did for Kodak. I really enjoyed those years I worked there. They used to make killer tuna melt paninis in their cafeteria area near the top of the tower and in the summer months I'd keep my car parked at work and just walk across the street to see the Rochester Red Wings play (AAA minor league baseball team).

OK, HN physicists: how did this work?
My first guess was that the beam of Cf252-emitted neutrons, when it hits the U235, triggers new neutrons moving in the same direction, rather than in random directions. This would ensure that any tertiary neutrons would join the crowd and help the amplification while not just heating the system up.
Or, maybe that's the point? It's a not-quite-critical collection of U235 that is pushed even closer to criticality by the Cf252, multiplying the Cf232's neutron flux by "up to 30 times". But, if the U235 neutrons trigger the same emissions as the Cf252 neutrons, then wouldn't that require a razor's edge of criticality?

It works just like a nuclear reactor. Neutron hit U atoms, those split and emit more neutrons in a cascade. The configuration is set up to not be self sustaining. It’s a matter of geometry, enrichment level and such. Therefore it needs a source of neutrons. Cf-252 is such source. It fires neutrons constantly but has a relatively short half life (you have to replenish it yearly or so).
> then wouldn't that require a razor's edge of criticality?
Yup. From the device description in its decommissioning plan:
Yup. From the device description in its decommissioning plan:
The CFX was a sub-critical assembly of uranium-2-35 surrounding a Cf-252 source. The function of the U-235 fuel was to multiply the neutrons coming from the Cf-252 source, which fissions spontaneously. The CFX was designed never to exceed a Keff of 0.99. The CFX assembly yielded sufficient neutron fluxes for applications such as neutron activation analysis.

The article is paywalled, but remember that the USA’s business giants during the Cold War were ran quite different than businesses today, especially with the fact that they had major internal R&D labs that did novel research in-house and relied less on transfer coming from research universities. Think about the other stories that you may have heard about Xerox or Bell labs. So Kodak having research abilities is not surprising. They also made the cameras and films for US spy satellites during the Cold War. They were not just a little company that made recreational film. They were a science and chemistry powerhouse.
When I was at university a lifetime ago, the country had a number of university research reactors. Some of their work could be.. and was.. replaced by computer simulations, but not all. Today there are zero. My impression is that not only is the UK public ignorant and fearful of nuclear, but of "labs" in general. Their view is informed largely by newspaper headlines and Hollywood movies.
Disappointing, for a second I thought I have found a solution to power my 8x5090 homelab.

Are they stupid at PM or just selling misinformation?

This matches other sources on the internet: a bomb requires about 15kg of U-235 [0] with a good use of neutron reflectors, and HEU by definition contains 20%+ of U-235 [1]. We don't know exactly what the U-235 concentration was in the Kodak device, but reasonable values would make the claim "roughly" correct.

Their SNM license was for “up to 93.5% enriched”[1] and their decommissioning plan describes them as MTR-type Al-clad plates. So I’d take a reasonable guess that these are at 93% nominal enrichment, like ATR and HFIR fuel plates.

HEU != 20% enriched -- 20% is more like the floor for considering it HEU. You need much more than 20% to make an efficient Uranium bomb.
At least it wasn't "though it takes at least the equivalent of 12.5 bald eagles of it to build an atomic bomb"
The whole article is a journalistic nothingburger.
The reason for the informal secrecy, as it was explained to me, is that every so often someone would find out there was plutonium etc in the basement and have a public freak out, including on occasion other (non-STEM) professors at the same university. These people would try to organize crusades to get it shut down because evil. Intentionally obscuring its existence greatly mitigated this drama. They appreciated us continuing the tradition of keeping it out of sight and out of mind from the general public.
The publicity around this Kodak case was an example of why no one talks about nuclear labs. The public cannot be trusted to engage in a discussion about anything “nuclear” in good faith. There are quite a few areas of science like this.
