@@alsmith20000 I stopped watching when the lady began talking about too much dependence on foreign suppliers for required energy and material. WHY??? Because the entire German economy is dependent on large quantities of imports and exports. Sabine should be able to elaborate on this. A recent statistic I recall had it that 85% of what Germany exports is also imported. Thus the large imports of natural gas from Russia was not a problem because Russia was a very reliable supplier. Having noted that, I am also in favour of nuclear power, having worked in that business. I live in Ontario Canada, and we get 65% of our electric power from nuclear power plants. 30% is from hydro-electric power plants (think Niagara Falls), the remaining 5% is generated by natural gas fired generators (peak shaving), and wind & photovoltaics. To depend on the latter two with a climate like Canada's is the height of insanity.

@@BasementEngineer Good observation, thanks.

I learned about radioactivity from coal plants back in 1982. I was serving onboard a nuclear aircraft carrier and one of the instruments that I had to check hourly was called the APD, or Airborne Particulate Detector. This was almost a gag since it always read zero, even though it was positioned between two nuclear power plants. This was true until we approached Naples, Italy -- at which point the APD readout started to climb. It didn't get very high, but it was noticeably elevated compared to normal operation. It turned out that it always did this when approaching Naples because they burned coal and there was a fairly stable inversion layer in that area which kept the pollutants in place. This would be similar to Los Angeles and smog. Anyhow, I found it amusing that naval nuclear power produced far less radiation that coal.

The biggest problem I see with both the original video and this response is that the expense of each power source per MWhr seems to have been calculated without worrying about whether it supplies base-load or not. Renewable energy only looks cheap when it's intermittency is ignored. Once you need to rely on it for a perpetual source it's true cost must include storage and release mechanisms. And they are horribly expensive even at smaller scale. In other words, I think a fair economic comparison would put nuclear well ahead of solar and wind. Especially since the production costs of renewables are more likely to sky-rocket than continue down as demand for the relevant construction materials increases by more than an order of magnitude under a renewables-focussed transition. Massive demand increase for materials, some rare and hard to extract, virtually guarantees massive cost increases.

Absolutely agree. Also comparing old nuclear plant designs to the latest and greatest in solar and wind isn't apples to apples. New nuclear plants (Gen 4), though unproven, hope to use passive safety designs instead of costly active safety systems layered on top a pressurized water reactor which also needs a reactor housing and a containment dome a thousand times bigger than the reactor volume. This is a huge driver in costs.

Investment bank Lazard (Apr 2023) finds that solar and wind plus storage is now competitive with natural gas for electrical utilities. Lazard calculates the following unsubsidized levelized cost of energy (LCOE) per MWh for new power plants constructed in the US: utility-scale PV solar: $24 - $96 utility-scale PV solar + storage: $46 - $102 geothermal: $61 - $102 onshore wind: $24 - $75 onshore wind + storage: $42 - $114 offshore wind: $72 - $140 combined cycle gas: $39 - $101 combined cycle gas with 20% green hydrogen: $156 gas peaking: $115 - $221 coal: $68 - $116 nuclear: $141 - $221 The price of LFP grid batteries is dropping like a stone. CATL is currently selling its LFP at US$70 per kWh in China, so companies like Tesla should now be selling their grid batteries in Western countries for around $150/kWh, whereas it was $300/kWh in early 2022. I just read the prediction that CATL will be selling its LFP for $56/kWh by mid-2024. Sodium ion batteries should be 30% cheaper than LFP and Salgenx says that it will be able to produce its salt water flow batteries for $5/kWh when it gets to scale, so grid storage is going to become dirt cheap.

It's not an either/or calculation. In locations where solar is most justified, it is also most needed when it's at maximum productivity. Ie. Storage isn't a need unless you're over-producing which for solar fields will never happen if done right. It would be foolish to size a nuke plant to cover those conditions entirely on its own, to then over produce the other 70% of the time. Also, your cost of materials argument applies equally to nuclear as it does to solar. In fact the most common type of solar is just silicon and tiny bits of boron and phosphorus, all extremely abundant without any mining, You seem to be cherry picking the solar technology to justify that argument.

We profit from selling uranium are great at mining and geology. We should only sell our mined uranium with the proviso it is returned to us for storage in deep underground geologically stable rock. Instead our nuclear waste is stored in a warehouse in industrial Sydney. Imagine the public panic if even low grade facility if say an airplane crashed into it. Storing properly we'd also be decreasing opportunity for nuclear proliferation. The niby's will never agree though.

Storing waste in a geologically stable area isn't exactly the "Best" solution. Well, it is the best pragmatic and economically viable solution. That said, the "Best" solution is storing it in the crust being consumed near a tectonic plate edge would be a proper means of recycling the waste. The heat, compression and forced combination with surrounding matter theoretically would cause some degree of Fusion of the waste. Depending on how far below the surface it is pushed of course. Even partial fusion would likely occur along with a distributed diffusion throughout the surrounding matter, minimising the consentration of dagerous levels with in the contaminated matter. It, however, would be prohibitively expensive to do and has a litany of risks and numerous potential issues that would lead it to go horribly wrong. It is theoretically the proper/natural way to return the material to the Earth to reuse like it does with all other matter. Heck, if Carbon Capture worked then the same method would be the right way to dispose of it. Retuning it deep uner ground to be compressed, heated and fused to form all forms of Cabides and Oxgides. But yes. Storage in deep and remote locations that are geologically stable is the the best Practical and cost-effective option. It's sadly just not a very practical extreme long-term solution, its kicking the can down the road for someone else to fix. Which, realistically, is the best we can do right now.

She claims scientists disregard results from their own experiments and studies when they don't suit their theoretical basis. I.E.: you run an experiment and expect result A but get B then you disregard the result and run it again until it results in A. She claims this is the reason why scientists have not made any groundbreaking progress in the last 100 yrs or so. I asked a friend of mine who did his phD in physics for some time but stopped it and instead now does a master degree in Machine Learning. He despises the scientists in physics, as he sees it as an industry of egomaniacs where everybody just wants to get his papers published. Still he thinks of Sabine Hossenfelder as somebody you have to listen to with a grain of salt. He thinks she is driven by a lot of spite, because she feels being treated wrong by her colleagues and thus wants to proof them wrong. This got her into a viscious cycle. She *needs* to be right, she urges to proof a point, not for science sake but to satisfy her own ego. I forgot the exact example he gave, but some of the things she states seem to be way out there. That's my friend's take on her. And he is not somebody who looks to kindly on physicists and careerwise turned his back on it.

He has done considerable work with thorium liftr breeder nuclear reactors. Anyway he has done most of theoretical work for molten salts since operation of other reactors being used for nuclear power.

Awesome video Elina both you and Sabine have my utmost respect for your videos and love both of your humor!

@17:15 What I think is the biggest omission in regards to the economics of nuclear power is that the rising price of construction is a direct consequence of the shutdown of the nuclear industry. If/once the renaissance of nuclear power occurs, the economics of scale will almost inevitably reverse the trend. Also heightened regulatory burden has steered the industry towards larger facilities with greater economic risks, something that the SMR technology is specifically addressing.

Sincere appreciation for your analysis and additional information on the findings.

I have been watching Sabine for some time now and have learned a lot. When KZread recommended your video review, I'll admit that I was nervous about having what I remembered as being a very well researched video called out.

Very nice, balanced view. My father was an electrical estimator who worked a lot on costing power plants. I remember once asking him what the best energy source was. He laughed and said there is no best - only the best for the conditions. Another interesting thing was his view on the safety of electricity generation. He mentioned he would not like to be in the path of one of the turbines if the bearing it spun on failed.

As usual, nice reaction. Normal you would say as Sabine’s videos are always very well documented, but you rocks it even more! Thanks for your commitment in this cause, it’s nice to see and hear friendly thoughts about a soooooooo controverses topic 😊 Best regards Elina!

For both nuclear and renewables, really the best way of storing energy right now is hydro (pumping water up into dams) which can also go into water supply storage too.

I've been following Sabine's channel for a couple years. It's cool to see a nuclear physicist's opinion on her video.

Very nice video! As a German I'm still very frustrated about our decision to leave nuclear energy (Sadly our last power plants closed a few weeks ago :( ) Also sadly the public sentiment here is still very very much anti nuclear, even all the new climate activists groups are anti nuclear, which frustrates me even more. I'm extremley pro Co2 neutrality, but how on earth should we manage to do that without nuclear energy? Why are there so few reasonable activists, who are not delsuioned by anti nuclear idealogy.... Now it's impossible for Germany to reach their CO2 neutarality goals in the furture, instead we actually have to expand our brown coal open mining pits , which are destroying vast parts of our landscape and emit tons of CO2.... Therfore thank you for the video, it may help at least a bit to educate some people, who aren't completley closed off by ideology

Almost all of the damage from Fukushima was from the tsunami and from the evacuation - not from the nuclear accident. Statistically the deaths from nuclear power is so low as to be almost zero.

Hydropower usually doesn't need electricity storage (11:17) because it either generates a constant stream of electricity (as baseload) or can store the water before and produce electricity as needed.

When I was a teen in the late 1970s, I had a science teacher that absolutely condemned nuclear power and ridiculed anyone who even questioned the thought that nuclear energy wasn't evil. It took me a few years to get past this dogma.

Nuclear is not evil. Nuclear weapons protect us in the short term, and I have had nuclear medical treatment. Nuclear power, however is a bit different. What is evil, is to license out volatile weapons technology to power companies, and to allow anyone to use it to compete in the cut-throat energy market when there are cheaper, cleaner and safer alternatives. Your teacher's mistake was to think that all nuclear is the same. You are making the same fundamental mistake, and the people of Three Mile Island, Pripyat (Chernobyl) and Futaba (Fukushima) might disagree with you.

32:30 I think Sabine misspoke here. The nuscale reactors are 3 meters in diameter and 20 meters tall (9x60 feet), not twenty feet tall.

Fukushima changed the risk analysis of Nuclear Power plants even in Finland. The the risk evaluation used to be that e.g. flooding must be designed for natural events that happen randomly once in 10000 years. Since the Fukushima that number is now 100000 years for most parts of the design. As a result, they built yet another backup power station for emergency cooling for very very rare events. (If I remember correctly, they previously had 4 backup power stations with full flood protection and they built 5th backup station on a nearby hill make sure it can never flood.) And as a Finn, I have to add that in my opinion, burying the spent fuel from light water reactors into the ground is simply stupid. I agree that some spent fuel is good to bury but the stuff that could be still used in everything else but light water reactors seems silly for me. It's like drilling oil, manufacturing jet fuel and burying diesel and gasoline into the ground because those are waste side-products.

Hi Elina. Love your t-shirt. Great vid.

Elina, this was a very good video. I watch a lot of Sabine, I typically agree with most of what she says. She offers well researched, reasoned, and logical arguments in her videos. The information is usually presented in a very organized and straightforward way and Sabine's opinions are not "knee jerk" but are well thought out and scientifically informed. I think your videos are, in this way, similar to Sabine's. Well reasoned and thought out and always informed by science. I'm a physicist and an electrical engineer so this of course appeals to me. Sabine covers a broader range of topics from the realm of physics than you do but then Sabine doesn't bill herself as our "friendly physicist" either. 😁 I very much enjoy your videos as well and I believe you fill a very valuable niche. As Sabine pointed out, people are in many ways irrationally afraid of anything nuclear and your videos do a lot to combat that irrational fear by replacing it with knowledge. In a friendly nuclear physicist way. 😊

4:45 This bit reminded me of a (possibly apocryphal) story about the time that Denver, Colorado had a tsunami warning. Apparently, when they installed their new Emergency Alert System, some technician accidentally connected one wire in the wrong spot, but it wasn't caught until after every television in a city famous for being an entire mile above sea level interrupted peoples' shows to tell them they were about to get hit with a giant wave of seawater.

I've just discovered your channel. Love the videos.

Elina I'd love to see you evaluate various reactor designs. One I'm quite interested in is Westinghouse's 450MWe Lead Fast Reactor. It will be able to be used as a waste burner & includes supercritical CO2 thermal storage.

Honestly glad I stumbled on this video seems like it'll be an interesting watch

It's important to note that after Fukushima, the German government not only had decided to phase out of nuclear power but also made the construction of solar power and later wind power way less attractive.

liked a few of your videos. so i hit that subscribe button! your video's are very interesting

Sabine is probably the best scientific communicator I follow. She's the most objective, rational (even when irrational subjects are involved), and has a laser focus when explaining a subject (so far everything I've seen of hers). This laser-focus is actually extremely important, because for regular people like me - we don't have high capacity of understanding complex scientific subjects anyway (yes some people might have some more knowledge in a subject or two, but another will have in different subjects - the average isn't as high as an expert in the field would be). So far even difficult subjects have been clearly explained, and what I really appreciate - there's no speculation or unfound assumptions (like for example many Standard QM videos are). It's nice to see to have such overlap of views with Elina. This is the first video of your I'm watching but I'm interested to see more. However in the beginning, when you said that currently there's no technology to store the energy from renewables (Solar, Wind ...) and to smoothen the Duck curve (ie to cover the periods when energy demand exceeds the energy supply). Besides batteries actually there are several technologies. Li-ion batteries are actually one of the more polluting energy storage techs. That and the current cost of Li-ion is what limits it to become the main solution. One that's older than li-ion batteries is pumped-hydro. But since pumped-hydro requires specific terrain and it affects wider areas there are solutions on the same principle but more adaptable. One is to drill deep vertical shafts and use materials much heavier than water as ballast. The advantage is it's still low tech (or operation; perhaps a little more mid-tech level of drilling), easier to scale as long as you don't have many restrictions in drilling in the area. There's the solution of storing energy in rotating disks/cylinders (aka flywheel energy storage). Historically flywheel-storage had many energy losses and high risk of malfunction on high rpms, but with modern techs controlling friction and precision of the axis of rotation the potential has been increased greatly. Flywheels while currently aren't the most long-term storage they're the biggest "batteries" that can release their energy the soonest. But what's one of the most universal techs is heat (& also cryo) storage. Nowadays they can be very well insulated in order to minimize thermal losses, and a temp. difference (in case of hybrid Cryo+Hot storages) of about 600°C can deliver theoretical max. efficiency of ~88% (in case us using liquid air/nitrogen @-196°C & Hot tank @ ~400°C), or real world efficiency of at least 55%. Yes most alternative energy storage solutions have considerably lower efficiency than Li-ion batteries. But unlike Li-ion batteries some are really low-tech and have almost zero amortization (while batteries have rather limited lifecycle and their production is both relatively expensive & polluting). Heat can be stored easily in sand or rocks, and insulation is also cheap and low-tech (like Starlite clones made from household ingredients. Nasa uses very similar solution as heat shield on the Parker Solar Probe - carbon foam, which happens to be the product of burning Starlite-like materials). Of course the best solutions as temp. insulators are air-gels but they're still tricky to produce and not very strong for long term use. Also using concentrated solar power (CSP) is much cheaper than PV panels and even after collection, storage, regeneration can still reach at least double the efficiency of (single-junction) PV panels. And the lower efficiency (compared to Li-ion batteries) can be easily compensated by harvesting more sunlight. Of course that would take much more surface than a nuclear power plant, but the only losses of these surfaces are that the area below them would have very little light left. Real-world efficiency of that cycle CSP-HeatStorage-ReGeneration could even increase with tech improvements as they're currently not mass produced and only designed case by case. Low-tech solutions that have little restriction to place is also more competitive than highly safe modern nuclear power plant.

i was on board with this video until she said this, this is a very bad take on her part, renewable storage is highly competitive and there are many options that are good at the moment, the jury is merely out on which one is best and people are stalling on investing into them because they're all expecting a big breakthrough soon so wanna save their investment for that, but renewable storage is a solved problem in many and/or most cases (it of course varies by many factors such as regional resources and type of renewable, while hydro and air compression storage work great in some regions, they work terribly in others as an example). Batteries help to fill the gap of the hardest regions/circumstances to store energy in, but energy storage is one of those fields where there is no single answer. The answer is 400 types of energy storage each being used in different regions and conditions.

Energy storage is a fascinating topic, probably worth revisiting again in 5y. Right now there are lots of claims and products just entering the stage, and it's impossible to tell whether they will hold their promises.

But Elina posited a very interesting problem (and I paraphrase): "do the calculations of costs include the fact that life time of a nuclear plant is double that of solar or wind"? Depending on the answer Sabine may have produced a fairy tale, and not an educational video. So... Average nuclear power plant (NPP) is calculated to last 40 years (some sources say 60 years), but when built properly and modernized (which is not as bad as it sounds) are good for at least twice that. So NPP is at least FOUR TO SIX TIMES longer in operation (wind and solar are now rated for 20-25 years, and by end of the life cycle their output is somewhere between 20 to 50 PERCENT LOWER THAN WHEN NEW. There are new tech coming, true, but barring real new materials this will be not that big of an improvement... Second point is that solar and wind depend heavily on geography. In some places (i.e. Sahara or Texas - both are at similar latitude) they work fantastically well, in others (i.e. central or Northern Europe)... not so much. Also is there heavy subsidization of solar and wind included in price? This is a very important question because France - with majority of it's energy coming from nuclear - has electricity prices much lower than Germany (which effectively is running on solar/wind and coal)... This is very, very important question to answer, because if this is the case of fudged numbers - because the whole comparison does not add up (especially when storage of energy is getting cheaper, too) - then what is going on?

No drilling, pumping, transporting, refining, distributing, then delivering of oil. I figure that fact makes burning anthracite coal relatively green,.....in my specific situation. No natural gas available in my area. Saving up for a geothermal heat pump. Unfortunately, installing one is prohibitively expensive. One ton of coal is less than $300 ( that’s high for coal at the mine) and has the same amount of “heat” as a standard 275 gallon tank of fuel oil.....which costs almost $1000 to fill these days. 😳

Top comment! I fear most people don't recognize the profound knowledge, the beauty of your comment. Comparable to me, as I ignored for decades the meaning of the question of Einstein, what differs an astronaut and a man, who is falling from a roof (the answer is nothing, they are floating without force). As you already wrote, the second phrase is more easily understandable, but not more correct.

The biggest problem is actually people not understanding the difference between correlation and causation. It isn't that statistics lie, rather people are too stupid to use them, too stupid to understand them, and too stupid to use enough variables in relation to the subject. Especially when it comes to likely hood of events.

I follow Sabina and it is nice to get a second take to her breakdown of a subject, please continue to do reactions of her videos. I will definitely watch them and like them.😊

Keep up the good work, I love your channel. I've always been fascinated by nuclear energy. I even snuck into the Chernobyl zone alone once.

We were advised in Zagreb, Croatia to stay indoors, close windows etc. I was (not very) young physicist then, and the chance had it that we just completed a study of radon concentrations in basements and buildings made of locally sourced concrete or brick in Zagreb area. To make long story short, increased radiation exposure from radon accumulating in poorly ventilated rooms, especially in basements or ground floors of buildings without basement was _much_ higher (but still tiny) compared to radiation from Chernobyl, at least if you refrained from rolling in the grass after rain.

I guess they were primarily concerned about strontium-90 which, to be fair, _is_ chemically somewhat similar to calcium (so it can, conceivably, be extracted into milk and then incorporated into bones), has long-ish half-life of about 29 years (compared to 8 days for iodine-131), and releases 546 keV beta particles (electrons) which are strongly ionizing. I read somewhere that there is still a measurable (but not dangerous - physicists are good at measuring tiny amounts of anything) amount of Sr-90 in fish in the Baltic Sea.

She spans across a lot of industries and technical disciplines, not every video can be a deep dive like this one. I know what you mean though.

I really wish that whenever the Chernobyl accident is mentioned, people would also take the time to point out that the reason for that accident was purely political. The Soviet leadership decided to run an experiment where they first disabled all safety mechanisms, and then initiated an unsafe startup of the reactor. They also ignored all the power plant experts that wanted to abort the startup for safety reasons. If you really want to blow things up, you can always do so.

Good thing we don't have this dangerous thing called 'politics' in the west. Remember when France had no power because half their nuclear power plants had to be shut down because they violated safety considerations?

Nuclear power is blue, not green. I can confirm this after having looked inside a reactor.

I like how the background music started when discussing nuclear safety, then stopped after the safety class was over. Great job Elina. I'm impressed and my concerns are comforted.

Sabine is probably my favourite science communicator. And I very much enjoyed your reaction and the input you gave. It's always gives a lot of confidence when I hear two competent people agree on the topic like this.

18:24 - That's actually a really smart point that I've never heard mentioned before! I'm pretty sure the graph was showing the cost averaged over its own lifespan independent of others, but to fairly compare the two, if a nuclear plant lasts twice as long as a solar panel array, the construction/decommissioning costs of the solar panels should be counted twice to fairly compare them

@meateaw

Жыл бұрын

Why would you include the costs twice? The costs are included already in the per kwhr figure. Every kwhr generated includes the building and decomissioning cost. Like, the fact that it is already included means if you need to compare the two, you are already including the longer life-time, that's the whole point of the LCOE. Here's an example. You produce 10 kwhr of electricity from your nuclear plant over its 10 year life time. It costs you 1 dollar to build, 8 dollars to run (over 10 years), and 1 dollar to decomission. LCOE 1 dollar per kwhr. ($1+$8+$1)/10kw = $1/kw (Note, the lifetime of the plant isn't in the equation - it doesn't matter how long the plant took to produce the electricity. It produced 10kwhr over its life, and its life had a cost (including decomissioning costs) The same maths works for all types of power generation, the lifetime is important for when you spend the money. But the LCOE calculation by its nature includes all the spending including decomissioning. our solar equivalent might be: 5 kwhr over 5 years, 1 dollar to build, 1 dollar to clean the panels over 5 years, 1 dollar to decomission. ($1+$1+$1)/5kw = $0.6/kw To compare it fairly to nuclear, due to "having to decomission twice" you could double the build, cleaning and decomissioning costs, so build it once, wait 5 years, decomission, build it again wait 5 years, decomission. $6 / 10kw = $0.6/kw time doesn't matter. LCOE takes it into account.

18:41 Loved your music moment! I hope you do that all the time.

Very interesting to get your perspective. Where I live (New Brunswick, Canada), the power company just did a big publicity release for their small (modular?) reactor initiative. I believe we already use wind (there are relatively reliable winds at the head of the Bay of Fundy), but not as much solar that I know of. I agree that each area and situation is unique and that, in general, a mix of sources (and storage) is the best strategy.

Excellent video (both Sabine and you). Maybe one day you could crack the numbers on the cost? Why did they go up so much? Did the cost of steel and concrete go up, are the safety requirements higher now than in the past or is there a corrupt monopoly driving up the cost?

@fnors2

I think some factors for price going up would be inflation, all the carbon taxes type of policies, and globalization. Inflation is an obvious one. Things got a lot more expensive in the last few years. Like a lot. The carbon taxes didn't help, as they make fuel more expensive. Which drives the cost of transportation, which also makes the prices of everything go up. So you get that all the base material cost more. Skilled workers cost more. Etc. Nuclear isn't as well established or "simple" like coal or gas. So you already had to pay a premium, it's just that this premium has been inflated even more by everything happening in the last decade. And then you get globalism. Nuclear tends to be a more "local" or "strategic" thing. Politically speaking. Nuclear proliferation and all. Like, the US and the EU definitely don't want to have to depend on, say, Russia or China for their nuclear needs. The reverse is also true. So you have to deal in your market, with all the regulations and higher costs. Compare that to solar or wind or coal. With globalization, the factories/mines can be set up in countries with little to no regulations to absorb the costs. It's not as big an issue if international relations break down in those cases. It just boils down to finding a new supplier. Nuclear needs _expertise_ to run properly and not just resources. Plus, I think a _lot_ of solar panels are manufactured in China. With ressources mined in Africa. And let's be real, those areas don't have the best workers rights, or ecological policies. So costs can stay low, if you are willing to close your eyes to whatever happens over there. TL;DR: Inflation and policies definitely played a role (indirectly, at least) in making nuclear more expensive. And those cost increase can't be sidestepped by moving manufacturing to less regulated countries outside of North America or the EU.

I just came across Sabine yesterday, and am delighted with her sensible way of thinking things through, not to mention her presentation. Elina came up in the sidebar, so I clicked, and was similarly impressed with well-organized and well-researched work (and equally good presentation). I look forward to more of both of them. While today's video indeed put a new perspective on waste for me (which was always my biggest issue), my fears have now shifted to the number of steps in the supply chain that will be distorted and abused in the arenas of business and politics. Democracy provides for the spread of ignorance and abuse, especially when the matters at hand are beyond the grasp of the voting public. Those things are outside of the scope of discussion in both channels, but they do play a part in the biggest picture. Enlightened autocracy is really the best form of governance -- until power is assumed by the heir or next apparatchik in line, at which point tragedy ensues -- so I remain cautiously democratic, with the understanding that it must always yield results reflecting a low common denominator. (I'm in the US, so that might color my point of view. Some other countries might be different, but I've never lived anywhere else.)

Any commercial power reactor would blush with shame if it would release the same amount of radiation that a coal-fired plant does on a daily basis. Not to mention the regulator would shut that particular NPP down faster than you can say it, to never let it reopen again. But because coal industry's dirty little secret is not known by the general public, they get away with it😒
