The engineering side of running reactors safely is a solved problem, the US navy has > 7500 reactor-years with a perfect safety record.
It’s also worth noting that the US Navy is the only organization with a perfect nuclear safety record.
My point being: by god, let the Navy nukes train everyone else!
During the investigation of the accident the Admiral that built and ran the Navy nuclear program was asked how the Navy had managed to operate accident free, and what others could learn. This was his response:
> Over the years, many people have asked me how I run the Naval Reactors Program, so that they might find some benefit for their own work. I am always chagrined at the tendency of people to expect that I have a simple, easy gimmick that makes my program function. Any successful program functions as an integrated whole of many factors. Trying to select one aspect as the key one will not work. Each element depends on all the others.
So recreating that accident free operating environment requires a lot more than just training. It would require wholesale adoption of the Navy’s approach across the entire industry. Which probably doesn’t scale very well. Not to mention the Navy operates much smaller nuclear reactors compared to utility scale reactors, and has extremely easy access to lots of cooling water, which probably gives them a little more wiggle room when dealing unexpected reactor behaviour.

Vs. coal?
Vs. not having enough energy? (eg. blackouts killing hospital ventilators, etc.)

Edit: because of HN rate limits, I can't respond to a sibling comment. I'll do that here:
> Their safety record is good, but can they generate power at a cost that's commercially competitive? If it's too expensive then the plan doesn't work.
Is a purely wind/solar + battery grid viable?
Wouldn't it be better to have a rich heterogeneous mix of various power inputs that can be scaled and maintained independently?
Oil, Gas, Coal, and random chemical plants have had much more significant accidents even in the US, but never made a blip in the public's minds.
Aren't France and Canada the ones to learn from at this point with regards to safe nuclear operation?
But submarine/ship reactors are tiny compared with commercial reactors and 5+ times more expensive (although its hard to break out the true lifetime cost of the reactor from the submarine/ship).
Even modern commercial SMR designs (a few by companies that make Submarine reactors) are likely to cost a couple of times more per MW than large existing reactors
BTW - The US Navy has lost 2 nuclear submarines, which are still being periodically monitored - page 7 https://www.energy.gov/sites/default/files/2025-09/NT-25-1%2...
It’s a very semantic claim.
They have lost nuclear submarines (USS Thresher), lost nuclear missiles, depth charges, torpedos and bombs. They have crashed nuclear ships and submarines.
Yeah, they haven’t had a nuclear reactor leak (that we know of).

I agree we probably need nuclear to bridge the gap until solar or wind can take over fully, but there are a lot of problems with nuclear and the most pressing ones are connected to the unwillingness of people to spend money before a disaster happens.
On top of that, uranium is a limited resource, it's extraction is (energetically) expensive and dirty and the storage of the nuclear waste is very far from a solved engineering problem. Storing safely stuff for thousands of years is just not a realistic scenario whatsoever.
All this is not to say we should just skip on nuclear power altogether, we can't afford that I think and burning all the fossil fuels will probably have more disastrous consequences. But we shouldn't close out eyes to the problems either.
Nuclear waste is small and solid, not a leaky green ooze like you see in the Simpsons. You can just bury it deep in a mountain, which is where you extracted the uranium from in the first place.

That would depend on the category of the waste:
- High level waste - Transuranic waste - Low level waste
where high level waste comes in two classes: spent fuel and reprocessing waste, the latter being liquid (possibly not green).
https://ieer.org/resource/classroom/classifications-nuclear-...
You can just bury it deep in a mountain
Belgium is notably lacking in mountains, which is why they now start building a site for low level nuclear waste storage, adding to the cost. For high level nuclear waste they have to build deep underground, waterproof, bomb-proof facilities at high expense:

As long as all goes well. Fukushima has a slightly different experience.
> You can just bury it deep in a mountain, which is where you extracted the uranium from in the first place.
Imo it's stupid to put nuclear waste in a place where you can't get at it anymore. In the ideal case we invent better reactors where you recycle all radioactive parts as usable fuel and the output is truly 'spent'.
I don't disagree with you that the pros of nuclear (as opposed to fossil) outweigh the cons. But there are cons, and eventually we'd be better off harvesting our energy from the sun.
More of a political problem, from what I hear. This is, if anything, worse: simply not knowing is a research problem, but knowing how to do it and yet having an influential group saying "no because reasons" could be genuinely insurmountable.
So imo not really a political problem.
China which is fairly sensible on this stuff and which plans to be world's largest nuclear producer by 2035 actually added 1GW of nuclear and ~300GW of solar last year because it's cheaper.
I'll give you maintaining existing nuclear makes sense. But as a British tax payer the cost of our upcoming Hinkley C is eye watering (£48bn https://en.wikipedia.org/wiki/Hinkley_Point_C_nuclear_power_...)
1. We’ve got a free fusion reactor in the sky and collecting and storing that energy is fundamentally cheap. Especially in a long term perspective when the materials needed to store the energy will be mostly recycled and practically free.
2. We’ve got a free fission reactor under our feet. Drilling deep enough expensive now but there’s no reason it needs to be. Se Quaise for progress in that area.
3. In a 50 year timeframe we don’t have any spare capacity to add more global warming from the thermal forcing of thermal power plants. Yeah you heard me right, thermal power plants contribute directly to global warming, and the effect is surprisingly significant. The good news is the effect disappears rapidly when you shut them down, unlike greenhouse gases. And we should certainly never shut down any nuclear power plants until we’ve eliminated greenhouse gas emissions. But at the same time, while we have an insane amount of greenhouse gases lingering in the atmosphere we can’t afford adding global warming from thousands of new nuclear reactors… like some nuclear proponents would have us do.
A 100 years from now, if we’ve brought greenhouse gases down again, that’s when we can start considering adding significantly more nuclear power. Though I doubt there will be any interest. Makes sense for space travel though.
I’m pro nuclear despite all that. But more from an R&D perspective.
"2025 also saw China commission 78 GW of new coal power capacity, which is more than India’s net coal power additions over a ten-year period from 2015 to 2024"
https://energyandcleanair.org/publication/built-to-peak-coal...
It needs the PR because it is so unconscionably expensive. The public needs to be primed to consent to indirect and direct subsidies.
The reason China, US, France, it is because it shares a skills base and supply chain with nukes.
The reason Sweden, Poland, Iran, etc. build a few plants is because it shares a skills base and supply chain with a nuclear weapons program they might want in a hurry one day. It's always obvious for those countries who the existential threat is.

> "The failure of the U.S. nuclear power program ranks as the largest managerial disaster in business history, a disaster on a monumental scale ... only the blind, or the biased, can now think that the money has been well spent. It is a defeat for the U.S. consumer and for the competitiveness of U.S. industry, for the utilities that undertook the program and for the private enterprise system that made it possible." — "Nuclear Follies". Forbes Magazine. 1985.
Notice that it was also them (specifically Russia, a major petroleum exporting country) funding those anti-nuclear environmental groups:
https://www.europarl.europa.eu/doceo/document/P-9-2022-00127...
They also fund major parts of the establishment - just look at UK politics and House of Lords.
There are plenty that are anti nuclear and don’t get Russian funding.
If, it was to be from some kind of storage, Extra capacity would be needed to allow recharging of the storage
Weather fronts move across the continent on a very regular basis; when the wind dies down, the sun shines more.
Obviously it’s possible for solar, hydro and wind farms to stop producing, but that’s what storage is for.

https://blackout-news.de/en/news/electricity-prices-in-germa...
Nuclear power would help to solve these problems, because it isn't intermittent.
In the meantime, mobile phones are still figuring out how to operate reliably globally, . But phone plans are hard.
Destroying a whole valley for hydro is something locals could easily oppose. Similar with huge solar farms. You can be a proponent of a technology but anti a particular project.
I also used to believe that but now I'm not so sure. Nuclear carries massive and unpredictable risks on failure. We can fairly well predict what will happen on catastrophic wind turbine failure, but with nuclear it is much more difficult. And what is arguably worse is that nuclear catastrophic failures are very infrequent and so we have very hard time estimating and thinking about probabilities of them happening.
Personally I think that keeping existing reactors running is better than the alternatives, but I'm not so sure about building up new reactors compared to building more predictable green energy sources.
"The health burden of European CPP emission-induced PM2.5, estimated with the Global Exposure Mortality Model, amounts to at least 16 800 (CI95 14 800–18 700) excess deaths per year over the European domain"
https://www.researchgate.net/publication/349938542_Disease_b...
https://www.sciencedirect.com/science/article/pii/S016726812...
But only nuclear accidents get the media attention, because they are big and infreqeunt. Similar to deaths caused by aircraft crashes vs deaths caused by car crashes.
Meanwhile coal kills millions each year (mostly the old and children).
And what are these predictable green alternatives? Only hydro is reliable and is heavily restricted by geo. We’d need massive breakthroughs in battery technology to make solar and wind reliable in most of the world (by population).
Look up historical weather patterns days with no sun and no wind, you need massive, massive amounts of energy storage.
A country can go from well functioning to disasterous shit show in 8 years.
What nuclear is is a wedge issue that can successfully split the opposition to the fossil fuel industry. People should be incredibly wary of the argument being forced into these positions, its artificial and contrary to the desires of people who want action on climate change who support nuclear and don't.
Looking at different party platforms here in Sweden (and similar parties in nearby countries), there is a major split between either supporting nuclear or supporting a combination of renewables and fossil fueled power plants (which sometimes goes under the name of reserve energy and other times as thermal power plants). Usually it is combined with some future hope that green hydrogen will replace that natural gas at some time in the distant future.
We could have people with positions that is neither a grid with natural gas nor nuclear, but I have yet to find that in any official party platform. Opposition to the fossil fuel industry should be a stop to building new fossil fueled power plants, and a plan to phase out and decommission existing ones. It is difficult to respect people who claim to believing in a climate crisis but then stand there with a shovel when the next gas peaker plant is being built, then arguing how bad nuclear is to combat the climate crisis.
Well yeah because the battery storage to do that is still exorbitant, at least for the time being. There are some situational options but nothing universal. Other than waiting for the cost of existing battery tech to fall the most promising option I'm aware of are the prototypes utilizing iron ore for seasonal storage.
But we now have two lessons that teach us that being anti-nuclear was stupid: the Ukraine war and the current US administration's adventure in the Gulf.
Not at all. Some people are depopulationists.
E.g. China is too small to have an isolated closed market for a competitive and efficient semiconductors manufactoring
Leaders are looking at Japan and they are panicking. Fascists are demanding more white babies.
Did those plants suddenly became manageable? No.
Did those plants suddenly became cheap? No.
Do we suddenly have a solution for the waste? No.
Have new uranium deposits suddenly been discovered? No.
They are only expensive because externalities of other solutions are not captures or are subsidised. Wind and solar are expensive if battery storage is included in most of the world.
Waste is mostly a solved problem. Much more solved that waste management for coal plants in any case (whom also produce a lot of radioactive waste in addition to producing tons and tons of co2)
We have more than enough uranium. Currently only a small fraction is economically mineable but we have played that game before with oil.
Just look at the statistics. E. g. https://en.wikipedia.org/wiki/Lists_of_nuclear_disasters_and...
To say that they're _potentially_ safe by waving at the US Navy is a fallacy for several reasons.
1. It's p-hacking. E. g. with the same technology the Soviets destroyed five of their reactors.
2. The world of civilian operators is completely incomparable.
3. Civilian power plants use different technologies.
> Waste is mostly a solved problem.
Not as far as I know. In Germany, for example, the search for a final disposal site is still completely open-ended, and the first final disposal site will not open until 2074 at the earliest, while, at the same time, the already collapsed storage facilities consume an enormous amount of money. I personally think it is absurd to assume that an underground nuclear waste storage facility can be operated safely over geological time scales. Needless to say there isn't even a single one worldwide for highly radioactive waste.
And to compare them with coal plants is classical whataboutism. "They can't be bad, because I found something other that's bad as well."
You're right about the minable uranium. That has changed over the last years, so the current estimate is 2080 in a high demand scenario.
But your criticism about the externalized costs falls short as well. Regarding the externalized costs, that is really hard to quantify and I don't know of reliable estimations. How do you want to come up with a number if you don't even know if humans still exist on the planet at that time?
What is clear is that for nuclear energy the majority of the costs is externalized. The bulk of the costs stem from the decommissioning of power plants, final disposal, and accident-related expenses. All three are typically passed on entirely to taxpayers.
The former German vice chancellor even said, he would agree [to build a new nuclear power plant] if <political opponent> found a private operator willing to build a nuclear power plant entirely without government guarantees, subsidies, or liability coverage.
It is more like being a firefighter and being opposed to airlifting icebergs to drop on fires.
Sure, you'll get water eventually and you might even extinguish a fire; but how long does it take to organise and deliver, what can go wrong in the process, what are the consequences of a mistake like dropping it prematurely, and why are we ignoring the honking great big cheap river right next to the house fire we are fighting?
I wonder how many people actually believe that we are in good shape so mankind should have no development whatsoever. Just stay as is or even go back decades just to preserve the environment. The first world need more energy because we're greedy and etc.
Yes hello, these are both my opinions, do I exist for you or not ;)? You can say that we are in a climate crisis AND be anti-nuclear.
Cities basically won't let you put a nuclear power station within a stone's throw, never mind in their midst. Have you ever visited London? There's a wonderful modern art gallery, on the side of the Thames called Tate Modern, and it has this enormous space which is called the "Turbine Hall". Huh. Tate Modern's shell was a 300MW oil fired power station named "Bankside". They burned tonnes of oil right in the heart of London until the 1980s to make electricity. People weren't happy about it, but they designed, built, and operated the station because although any fool can see there's toxic smoke pouring out of it into your city, electricity is pretty useful.
In practice nuclear power stations get built somewhere with abundant cheap water, far from population centres yet easily connected to the grid. England has more places to put a Nuke than say, a Hydro dam, but they are not, as you've suggested, "geographically independent", unlike say solar PV which doesn't even stop you grazing animals on the land or parking vehicles or whatever else you might want to do.
Compare:
If you believe COVID exists you need to use hydroxychloroquine.
It makes you sound like you don't even believe in the problem you are proposing an (unpopular with experts) solution for.
That is a very uncharitable reading of what I'm saying.
What I am saying is that if you're serious about believing climate change is a large threat (I do), you should be all-in on known solutions for reliable grid-level power. The current fallback for when renewables can't meet grid demand is burning natural gas in modernized grids and coal in grids stuck in the 1800s.
> unpopular with experts
How much of this is based on how expensive it is to bring a powerplant online? How much of that expense is based on endless lawsuits from environmental groups and weaponized environmental laws? Why can the navy without those restrictions build safe reactors for ~$2million/megawatt?
Fundamentally, unless you know the Navy's answer and can apply it to override those lawsuits, it doesn't matter: politics can't be wished away just because the wrong people have power.
> The current fallback for when renewables can't meet grid demand is burning natural gas in modernized grids and coal in grids stuck in the 1800s.
Increasingly not; as with all things, you have to aim for where the ball will be rather than where it is, and for this topic that implies that for any given proposed new gas (or nuclear) plant you have to ask about the alternatives, which also include "how fast you we build energy storage, and what would it cost?"
Just leave that part out, it only detracts from your message.
"I think environmental orgs should support nuclear as it is low carbon and generally aligned with their goals. I'm disappointed that many of their members seem to be unaware of the true record on plant safety, particularly compared with coal"
Adding anything about them not believing in climate change makes it sound like you are repeating talking points you picked up from fossil fuel funded propagandists, who to this day are pushing that message.
(Your opinions on nuclear also reveal that media diet, but in a much more subtle way).
Pretending it's all the fault of the bad environmentalists is a bit ridiculous. A nuclear powerplant is a tricky thing to create. A lot of projects had delay, often not due to any environmentalists or anti-nuclear people, but because the parts failed their internal control, which demonstrates that it is tricky to build. A nuclear powerplant is a huge provider that cannot be turned online for usually ~10 years, so you can also understand the complexity and the uncertainty: we are not able to predict the price of electricity or what will the electricity grid will look like in 2-3 years, and yet they need to predict it for a given region in 10 years.
And some environmental laws are frivolous or turned out the be incorrect (the same way some people who at the time were against some environmental laws turned out to be incorrect years later), but some laws are just legitimate and it is simply not fair to pretend that the opinions of some people should just be discarded because you have a different opinion. I myself don't always agree with some law, sometimes anti-nuclear, sometimes pro-nuclear, but a given fraction of these laws will exist, it is just the reality. It's like saying "communism would work if it was not for people who don't like communism": people who don't like communism will always exist and if your model require a world where it is not the case to work, then your model is stupidly unrealistic.
I truly can’t comprehend where this massive boner for new built nuclear power comes from. Sci-fi?
You’re putting the answer you want to hear (“because they are nuclear fans”) in the question, making it extremely obvious but then stating it is “odd”, as if the answer wasn’t straight forward.
Disingenuous – is the word describing this, I believe.
Also you need to check your concepts. “Climate change” is what we want to prevent (more like catastrophe, really, by now).
Building lots of new nuclear instead of doing the cheaper option of tons of batteries and renewables, only makes sense in a few geographic locations. Not all, or even most!
Even keeping old reactors running gets super expensive as they get past their designed lifetimes, and very often doesn't make sense.
The engineering is indeed already done for electricity, and storage and renewables are cheap and getting cheaper. Nuclear is at best staying the same high cost, and getting more expensive is these large construction projects rise due to Baumol's cost disease.
Opposing more nuclear in the US in the 1980s wasn't fully irrational, the US managerial class have way overbuilt nuclear and we didn't need all the electricity. Then we didn't have much growth in
The far bigger fight for climate these days isn't electricity: it's car-centric living, it's the anti-EV and anti-battery advocates, and to some degree it's retrofitting the wide variety of highly-cost-sensitive industries, such as steel or fertilizer or concrete, to use carbon neutral methods. Or maybe sustainable aviation fuel.
Nuclear had it's chance to be a big contributor to climate action back in the mid 2000s and 2010s, it failed that challenge in Georgia at Vogtle, in South Carolnia at Summer, in the UK at Hinkley Point C, in France in Flamanville, and in Finland an Olkiluoto. Every one of those failures is a very good reason for a climate activist to oppose nuclear.
All of transportation, including commercial + aviation, in the US is 28% of greenhouse gasses, electric generation is 25%. They're functionally equivalent. Further, a common refrain from environmentalist messages I've seen my entire life is that "every bit counts" and that's used to justify why an individual should say, buy an EV or recycle.
Personally, I agree with that logic, but I also think grid-level power sources matter more.
If you think we're in an existential crisis then costs be damned, shutter every natural gas and coal plant and replace them with nuclear as quickly as it can be built under extremely aggressive bypassing of red tape that's not safety critical. The US and EU print trillions to fund wars, if it's an existential risk, certainly we can do the same to cut carbon.
If it's a pragmatic decision to slowly shift to wind + solar based on costs (while still burning a lot of natural gas for when the wind doesn't blow and the sun doesn't shine), that's fine, but it doesn't really convey an existential urgency.
I agree that this means few decision makers believe climate change will literally end human life, or end industrialised society, in the near term. I disagree that any problem should be ignored unless it's existential.
This is not the cheaper option.
You need to have batteries that can store power for at least a week to have base load as reliable as nuclear power. There isn't enough battery capacity in the world to do this for a state like California, let alone the whole country.
This is a complete myth, somebody pulled "a week" out of their butt a decade ago, it gets repeated a ton, but it's not based on reality or studies or numbers. This is a consistent problem with online nuclear advocacy: there's no basis for the numbers, nobody calculates anything, and if they bother to do a calculation they only calculate the upper bound and then assert "see look a big number" and say that's a proof of impossibility.
What event requires a week of storage? Nobody can name one! When has there been a week with zero generation? No one can name it! The assumptions that one has to make up in order to make a "week" even sound plausible are in turn themselves so implausible.
> There isn't enough battery capacity in the world to do this for a state like California, let alone the whole country.
Imagining there's a fixed battery capacity is a very short sighted view, it's growing by 10x every year.
So let's take your "week" as the measure, even though it's wrong. If we're at 2-3 TWh of world battery production capacity in 2025, that's 4 days of California demand. By 2031 or 2032, we're going to have 20-30TWh of battery production.

It wasn't the weird enviors that stopped nuclear in the US, they don't have much power. What really stopped it was that the industry ordered too many reactors at once in the 1970s, they didn't standardize on a design, they had a ton of construction projects that were starting to run long, and then TMI happened and scared everyone because TMI had been mismanaged so much, leading to oppressive regulation on the already-failing construction projects.
The reason nobody built nuclear for 30 years after that was because it didn't make financial sense. The only reason any of the utilities signed on for new reactors in the mid 2000s was that state legislatures passed bills saying that the public would pay for any cost overruns from construction, rather than the utility! That's how bad of a financial deal it was. And the disasters at Vogtle and Summer show that the utilities were right to not want to build without passing the buck to others: nuclear is a financial disaster.
People want to put on rosy-colored glasses and look at the best possible picture of nuclear, rather than the messy full picture, which involves tons of cost overruns, and all the failed projects that simple did not work.
The US nuclear industry could have done all sorts of things to succeed: they could have standardized like France, they could have done Candus like Canada, whatever. But they didn't and it looks like they can't. We go into climate action with the industries and technologies we have, not the industries and technologies we read about in scifi.
Ignoring the fact that the nuclear plant already exists, this still seems like the right way to go mostly because it's impossible to build this nuclear power plant for $16B in the US anymore (or so it seems).
After some research, I learned that thermal powerplants (coal/gas/oil) completed in 1985 cost about 0.8B to 1.2B USD per GW. 5.6B USD in 1985 for 2GW sounds like a terrible price -- at least twice the cost.
Then 7B in 2046 money which is probably $15 today.
So when you compare average cost per year over the complete expected lifetime of the plants, nuclear is good, but when you compare the up-front cost to build it, yeah it looks bad.
Another thing is that nuclear in the US is far more costly than in e.g. France. The key is that France standardized a few reactor designs that they kept building again and again, which made both construction and maintenance cheaper over time. While in the US, each nuclear plant is a unicorn, which can perhaps result in better individual designs but ends up more expensive.
Cumulative emissions matter. We simply don’t have the time to wait the 20 years it takes to build new nuclear plants.
Taking china as an example they currently build solar, coal and nuclear. No country is building only solar/batteries.
Further if we build more nuclear we'd be better at it and it would be cheaper.
100% solar is a straw man though, as much as the simplicity of it sounds nice.
> Further if we build more nuclear we'd be better at it and it would be cheaper.
This is far from being clear, nuclear is one technology that tends to have increased costs the more we do of it. Even in France!
The costs of the French nuclear scale-up: A case of negative learning by doing https://www.sciencedirect.com/science/article/abs/pii/S03014...
Human labor is very expensive, and every time we make humans more productive, that makes human labor more expensive, because their time becomes more valuable. Technological growth does that.
The cost of nuclear is primarily in labor and long-term financing, due to the very long lifetime and upfront labor cost. Until somebody has some sort of technological breathrough to decrease the labor cost of nuclear, it's not going to be able to compete. Even decades ago it had trouble, and now it's far worse.
Simply saying "use PV plus batteries" really does not engage with the scale of storage required. The US uses 12,000 GWh of electricity per day. The world uses 60,000 GWh of electricity per day. Annual global battery production is around 1,500 GWh, and only ~300 GWh of that production is used for grid storage.
Even just provisioning enough batteries to satisfy the requirements for diurnal fluctuations of solar is far beyond the scale of what battery production can provide. Let alone fluctuations due to weather and seasonal output changes.
The amount of baseload we technically need can be pretty slim.
Take Denmark: fossil powers just 9% of their electricity generation, the majority of it is wind and solar. Wind is strong in evenings/nights, solar during the day.
Then they have biomass (indirect solar) as a form of baseload, more sustainable than coal/gas.
Then there's interconnectors, they're close to Norway which can pump hydro, and Sweden, each day about 25% of the electricity is exchanged between these two countries, and that's a growing figure.
With more east/west interconnectors you could move surplus solar between countries. Import from the east in the morning before your own solar ramps up, export your midday surplus west before theirs peaks, and import from the west in the late afternoon as yours fades.
With interconnectors you can also share rather than independently build peaker capacity. Because a lot of peaker plants only run a small amount of time and therefore much of the cost is in the construction/maintenance, not the fuel.
And of course there's storage, which will take a while to build out but the trendlines are extremely strong. Just a fleet of EVs alone, an average EV has a 60 kWh battery, an average EU household uses 12 kWh per day so an average car holds 5 days worth of power a home uses.
And then finally there's smart demand. An average car is parked for more than 95% of the day, and driven 5% of the time. Further, the average car drives just 40km a day which you can charge in 3 minutes on say a Tesla. Given these numbers (EVs store 5 days of household use, can sit at a charger for 23 hours a day, and can smartly plan the 3 minutes a day of charging it actually needs to do) just programming cars to charge smartly, is a trivial social and technical problem in the coming 10-20 years.
Given this, baseload coal/gas can really be minimised the coming decades. It's not going to go away as a need, but I don't think it requires gas/coal or nuclear long-term going forward.
As an insurance against unspecified lack (how much for how long?) of wind and solar (and batteries, cable capacity, hydro, etc.) base load is supposed to swoop in and save the day when those temporarily fail locally. So, it's a valid question to ask how much insurance we need against that. Nobody seems to really know. There are loose estimates of course. And people seem to assume it's months and that renewables are going to 100% be offline throughout that very very long period. In reality in most connected energy markets, we have a short gap of a few weeks or so in winter at higher latitudes of reduced output that we already manage to cover with flexible generation.
It's more constructive to think in terms of dispatchable power rather than base load. When the sun doesn't shine or there is no wind, it's nice if you can quickly bring online additional generation, tap into battery reserves, or bring in power from elsewhere (via cables). That favors flexible power, not inflexible power. Nuclear and older coal plants are a bit inflexible. Shutting down and starting up a nuclear plant is really slow and expensive and requires a lot of planning. And especially older coal plants need quite a bit of time to bring their boilers up to temperature such that they build up enough steam pressure to generate power. Until then, they are just blowing smoke out of the chimney. Modern coal plants are a bit better on that front. Same with gas plants.
The modern ones only need about 10-20 minutes or so. Still quite slow but something you can plan to do. Slow here means expensive as well. Because shutting them down when there is a surplus of renewables (which is a very common thing now) is really inconvenient. Which means consumers have to pay extra for perfectly good electricity from renewables to be curtailed. That happens by the GW in some markets and keeps consumer prices higher than they should be because they have to pay for gas/coal that is technically not actually needed.
Batteries have a much lower LCOE than gas or coal plants (never mind nuclear) and it's being produced by the TWH per year now. A lot of markets are serving much of their peak demand using batteries now. Australia and China are good examples. Even in the US, you see batteries being deployed at a large scale now. That's starting to push gas and coal out of the market. A gas peaker plant that rarely runs is just really expensive.
Gas is far better suited economically to backstop a variable grid. I wish it werent true, because i dont hate nukes, but it is just economics.
I will also point out that california is down to 25% fossil sourced power in 2025, from 45% in 2022. Due to renewables and batteries, and there's far more coming. The amount left to backstop on gas in a few years could plausibly be 10%! which is amazing.
The transition from coal to gas gave us cleaner air (and less CO2) but it definitely also had costs, some of them in the form of many thousands of dead Ukrainians, some of them in the form of concessions to the US.
This doesn't go away under socialism/communism/collectivism. If you set the price too low, you either have to build far more production capacity at public expense than needed, or you cope with regular blackouts.
The complexity now is doing it without delays. China shows that it can be built very cheap and fast with good supply chain
I mean, thank you, the USSR already showed this, no more is needed.
how much this would cost for the same guaranteed power output?
would it be more or less than 21B?
how it would look like in areas that have winter with snow?
Because these plants run for 80+ years (some countries are now considering 100) while most renewables run for 25 at most. And also because `plus batteries` doesn't exist. The world battery capacity isn't enough to power California for a single week. Large scale battery technology isn't even in its infancy, it just doesn't exist.
Don't forget, you've paid for the nuclear power plant once. You will pay for a new set of renewable capabilities every 25 years in <current-year + 25> dollars.

1. https://en.wikipedia.org/wiki/Diablo_Canyon_Power_Plant
The Belgians apparently typically invert the meaning of . and , in numbers (from how they are used in the US).
I would guess Europeans tend to be better at SI units than people from the US. And let's not mention the the cancer of changing the value of G depending on context.the largest solar plant in california is Ivanpah. It made 85GW/year. Thats 97MW/hr.
It would take 20 clones of Ivanpah to match one diablo canyon. Ivanpah took 4 years to build, cost 2.5B and was in discussions to close because it’s not cost effective.
https://en.wikipedia.org/wiki/Ivanpah_Solar_Power_Facility
my whole point is solar is great, but the insane scale it requires to get reasonable output is really underestimated. you would need solar fields 100sqmi big. probably many of them. solar alone won’t be the future of humanities energy needs because it’s not efficient enough. we should still keep building solar. but if we aren’t building nuclear too its not enough growth
MW/hr is a nonsense unit for generation capacity. The 2 reactors at Diablo Canyon each generate around 1.1GW of electricity (not MW, and not “per hour”, watts are already energy/time.)
> the largest solar plant in california is Ivanpah. It made 85GW/year. Thats 97MW/hr.
Ivanpah is a badly designed plant that isn't representative of CA’s solar generation (which is largely distributed, not large utility-scale plants) and is being shut down, but also these numbers are both nonsense units and unrelated to the actual stats.
Ivanpah’s peak output capacity is 397MW, it was intended to produce around 1TW-h per year, and it has actually produced an average of 732GW-h per year (equivalent to an average output of around 84MW).
Ivanpah is is not the largest solar power plant in California. It's an experimental solar-thermal plant. Talking about megawatts per year is not a meaningful term (megawatt-years would be). Ivanpah despite its much talked about failures delivers between 350 and 850GWh per year.
The largest solar plant in California is Edwards Sandborn, producing somewhere around 2500GWh per year (it's newer so numbers are less published).
Diablo Canyon produces around 18000GWh/year, which is huge.
But with all costs combined, Diablo's price per MWh is close to ONE HUNDRED AND TWENTY DOLLARS off of a massive initial capex. Modern solar battery installs trend towards $30-60 for the same output.
So I'm sure your tour guide had some neat numbers but you should be careful not to repeat them verbatim (or unremembered).
Apparently there also used to be a phaseout policy which is being rescinded: https://www.msn.com/en-ca/news/other/belgium-and-czechia-ram...
I'm not keen on new nuclear (time and cost as much as anything else), but it's a terrible idea to phase out operating nuclear plants which are still safe and within their planned lifetime.
Further background: https://www.world-nuclear-news.org/articles/fifth-belgian-re... (2025)
> "Belgium's federal law of 31 January 2003 required the phase-out of all seven nuclear power reactors in the country. Under that policy, Doel 1 and 2 were originally set to be taken out of service on their 40th anniversaries, in 2015. However, the law was amended in 2013 and 2015 to provide for Doel 1 and 2 to remain operational for an additional 10 years. Doel 1 was retired in February this year. Duel 3 was closed in September 2022 and Tihange 2 at the end of January 2023. Tihange 1 was disconnected from the grid on 30 September this year."
> "Belgium's last two reactors - Doel 4 and Tihange 3 - had also been scheduled to close last month. However, following the start of the Russia-Ukraine conflict in February 2022 the government and Electrabel began negotiating the feasibility and terms for the operation of the reactors for a further ten years, to 2035, with a final agreement reached in December, with a balanced risk allocation."
It seems there has been a complex balancing act which any owner of an old car will be familiar with: spend more money on keeping it operational, vs scrapping.
Funnily, I have almost the opposite view. I'm terrified of old nuclear because those first gen power plants are all missing a lot of safety lessons. Nuclear disasters happen at old plants.
I want old nuclear plants to be either upgraded or decommissioned. I have much less concern about new nuclear (other than it taking a very long time and an a lot of money to deploy).
A healthy social attitude to nuclear would be to require periodic upgrades or decommissions as the plant ages.
You can upgrade certain components, and safety systems. However things like the containment structure or pressure vessel can't be changed. You for example can't retrofit a core catcher, but you could improve the turbines, I think Steam Generators as well, replace PLC's, Tsunami proof your site by building a larger tsunami wall / making your backup generators flood proof...
These reactors can be made safer, but they all still have a foundational design flaw which means the ultimate goal should be replacing rather than continually spending money reinforcing.
One might object that there is selection bias in the original claim, due to the slowdown in construction of recent plants, but that is a separate issue. A more thorough investigation of the causes of all events leading to a significant degradation of safety margins would be needed to determine whether and how older designs are inherently more risky and whether that risk can be adequately mitigated given the constraints imposed by their design.
The fact that, prior to Chernobyl, there were several foreshadowing incidents with RBMKs which should have raised serious concerns, suggests that 'lessons learned' isn't much of a reason to be satisfied with the status quo.
The safety lessons we learned from all gen 1 reactors was to apply passive shutdown mechanism where if input power fails fission ultimately stops. That's not something that can be applied across the fleet because it requires more infrastructure and an almost complete redesign of the reactor's setup. Which is why these early reactors all have a potential risk of thermal runaway.
Edit: It looks like all gen Is have been decommissioned as of 2015, which is great. But we really should now be talking about decommissioning gen IIs and leaping forward to Gen IVs.
You used plural? What disasters are you talking about?
Even Chernobyl wasn't technically first generation (not that it has anything to do with power plan safety in western countries anyway).
Three Mile Island kind of proved it was fairly safe given that's the worst disaster to ever happen without any external factors (like tsunamis or being designed and run by soviet engineers..)
> the worst disaster to ever happen without any external factors
The problem is external factors happen. You can’t just raise your hands up and say “wasn’t my fault,” when they do. A tsunami washing over a solar farm would be a lot safer than what happened at Fukushima.
https://en.wikipedia.org/wiki/Lists_of_nuclear_disasters_and...
Tell me you don't work in energy without telling me.
Most heavily regulated industry on the planet - constant upgrades and safety reports.
There's a reason new Gen II plants cannot be built, and all the regulations and safety reports in the world will not fix the fundamental design flaw of these plants.
We can mitigate and make meltdown less likely, we can't eliminate it without replacing the plants all together.
Even assuming all bad stuff, nuclear is statistically ok https://ourworldindata.org/safest-sources-of-energy
Time and Cost seem like excellent reasons to get started now, so we can finish by 2035 and get some materials purchased before inflation gets even worse.
All of the excellent arguments Pro-existing plants apply to new ones too.
I think people have missed how much of a hockey stick graph renewables deployment can look like. https://edition.cnn.com/2025/05/01/climate/pakistan-solar-bo...
"Fish disco", for example.
Like maybe you're right... why not also support Nuclear plants, which we in fact need for baseload energy? Surely there are better places to cut the budget than other carbon-free energy sources.
I have no argument with building out solar and wind maximally. I will always push for new Nuclear as part of the mix.
you people have been saying that for at least twenty years. In the meantime the renewables have failed to produce a noticeable change in my part of europe, sentiment is increasingly pro-nuke but your adage keeps things still. Of course yf you never start, you never finish.
Skill issue in your part of Europe, then. In my part of Europe, https://grid.iamkate.com/ is currently reporting 95% non-carbon sources, 85% renewables, and a power price of −£12.03/MWh.
> twenty years
When it comes online, Hinkley Point C will have taken 20 years from first approval. Too slow.
I really don't think costs and delays are well understood. The costs are astronomical and in the UK the cost of energy has been monstrously subsidized. Consumers (public) are paying for this before the plants are running and for hundreds of years after they are running.
I wouldn't call myself anti-nuclear however as in terms of base load, sovereignty and environmentally it strikes me as hitting the sweet spot.
But I don't think people really appreciate how expensive it costs the public over the lifetime (even if "day to day" cost per MWh compares favourably with other sources), and how long it takes to get running. Even small modular reactors fail to address this.
UK is not energy independent so its not a good example.
It's certainly not £0.01203/kWh, or even in the same order of magnitude.
Later
(For context for non-Brits: there is a price cap of £0.2467 kWh currently, which many people are paying (or very close to that))
As of writing this comment our energy mix is 35.69% solar, 23.19% nuclear, 26.66% nuclear imported from Slovakia. The rest is hydro and solar from Austria and about 5% gas and biomass.
In my opinion clean electricity is an almost solved problem, especially as storage gets better.
More electricity in Europe comes from renewables than from either nuclear or fossil, with renewables rapidly approaching 50% market share. Several countries (even the non-hydro-heavy ones) are already showing multi-day periods where renewable electricity exceeds 100% of demand.
If your part of Europe isn't showing a noticeable change, perhaps it might be because your part isn't trying?
I don't know, but I've seen quite noticeable change.
First, you spend 20 years paying several times more for fuel and electricity because "we need to fight global warming" and "ensure energy security from those russians," and then they tell you, hey, global warming is actually worse than ever, and yeah, we are dependent on the russians.
As you explain in your next paragraph, none of Belgium's power plants are within their planned lifetime. Tihange 1, Doel 1 and 2 were operating on an extended service cycle for a decade before their shutdown. The two youngest reactors (Doel 4 and Tihange 3) surpassed their planned lifetime last year.
This is pretty much the summary of the whole discussion. Building new nuclear is a debate, seeing as renewables are dirt cheap it might or might not make sense to build new nuclear reactors that take a fuckton of money and many years to come online.
Shutting down existing nuclear capacity to replace it with Russian or Saudi or Qatari oil and gas though........
It’s a proven technology with decades decades in service.
We actually don’t know m any of the long term risks and unintended consequences of providing wind / solar + batteries at scale.
What rational is there to scrap the one and mandate the other?
The wind and sun already exist, we've been living with these "long term risks" for the entire time already. Risks like hurricane damage, skin cancer, heat exhaustion, the thing is that harvesting this energy isn't where that risk comes from, the energy was already dangerous.
That's the same lesson for the thermal plants. The nuclear reaction isn't directly how you make energy, it gets hot and we use that to make steam and we use the steam to make electricity, but the dangerous part wasn't the bit where we made electricity. Burning coal, again, you make heat, heat water to make steam, steam drives electricity turbine, but the dangerous parts were the exhaust is poisonous, the ash is poisonous, you're unbalancing the climate, and none of that is the electricity, that's from burning coal.
Releasing energy is dangerous, but the wind and sun were already released, there's nothing to be done about that, the decision is whether we should harness some of this energy or whether we're idiots.
No one said "scrap", you're making up a lie and arguing against it. They're saying keep one and build more of the other.
I have lived in a country that was reliant on hydroelectricity and the consequences of a drought were severe (literally days of power cuts, water cuts because of the lack of power...). Part of the solution was to build coal and oil power. Surely nuclear is better than coal?
Built facades and roofs out of glass-glass PV laminate. We have the technology from glass roofs/facades; you just add glass-catching-mesh/insulation below because you can't use the insulated multi-pane window glass construction with safety lamination and solar cells all three together.
With nuclear and centralized distribution you would still have to upgrade the grid for 10s of billions, just because of electric cars and electrification (and general maintance).
But renewables and batteries make this so much worse, specially once you talk about long distance renewable.
One you are talking about building solar in Greece and then talk about how nuclear is 'to expensive and slow'.
On the other hand, nuclear isn't a viable peaker plant option either. Virtually all of its costs come from paying back the construction loan, so a nuclear plant which operates at an average capacity of 10% will be 10x as expensive as one operating at 100% capacity. And 10x higher than the already-highest cost isn't exactly going to be competitive when battery storage, carbon capture, hydrogen storage, or even just building spare capacity are also available options.
New renewables are approaching the marginal running cost of nuclear that is still within their intended life span.
It would need to be shown that an expensive refurb is better than running it down efficiently while building out new renewables as far as bang for buck in getting off imported gas.
Yeah, but they last the majority of a lifetime. If you look at areas that built out nuclear 50 years ago, their kids and grandkids have still been benefiting from those infrastructure choices. They've been politically agnostic, because, once built, they're there. They're also relatively clean, and insensitive to the weather.
I'm a big advocate for renewables, but it's hard to not also advocate for nuclear to be in that mix.
It's not hard to argue that new nuclear should be added to the mix. The cost and time required to build them is non trivial. During that entire construction time you can build renewables substantially faster and for a lower price. And while you're building the prices continue to go down, meaning it gets ever cheaper. Then there's also the cumulative CO2 savings of getting the green energy faster, 1GW in 15 years requires 15 years of lost CO2 savings, but a 1 GW of renewables in 2 years saves you 13 of those 15.
I completely agree, but that's a massive "but". Belgium's nuclear power plants are mostly known for their reliability issues.
They are outdated 2nd-gen PWR reactors, designed by a company with no other nuclear experience, operating in some of the most densely populated areas of Europe. Keeping them operating long beyond their original design lifespan probably isn't the best idea - and it is almost a certainty that cleanup costs are going to be significantly higher than expected.
To me it sounds like Engie has struck an incredible deal by offloading a giant liability to the Belgian government.
Also remember that large parts of a nuclear plant is replaced over its operational life. Control systems, steam generators, turbines, generators, tubing, valves etc.
What stays is the outer shell and pressure vessel. A nuclear plant doesn't just "work" for 60 years. And there's no trouble designing renewables with a 60 year lifespan.
We just don't do it because spending money on getting their expected operational lifetimes from decades to 60+ years is betting on extremely uncertain future returns.
They do degrade over time, especially due to weathering of the seals and UV exposure, but all the quoted numbers are worst-case.
(Inverters are more complicated products and may need more frequently replaced)
I also wonder. Is it the implied danger over those tens of thousands of years or would it end up being something more similar to Ramsar in Iran long before that?
By "waste" do you need unused nuclear fuel? We can reduce the "waste" if we wanted to (see France), but it's cheaper to dig up more fuel.
The '10,000 year' thing is interesting: the nuclear "waste" that lasts that long is actually the stuff is not that dangerous. It can be stopped by tinfoil, and the only way for it to harm someone is either eat it or ground it into powder and snort it like cocaine: just being around it is not that big of deal.
The stuff that will get you is primary the stuff that is still around in the cooling pools for the first 6-10 years after removal. After that, there's a bunch of stuff that's around for ~200 years that you don't want to be touching. Once you're >300 years in, the radiation that's given is higher than 'background' in most places, that's why it's considered "risky".
Otherwise, as Madison Hilly demonstrated, it's not that big of a deal:

German Greens absolutely love your argument, but compared to the pollution that we produce everyday and which kills people and animals every day, waste storage is a nothingburger.
This is a different choice because the car analogy usually has "buy new one" as a term. Not having to build a new plant makes the choice far less controversial and also cheaper.
Worst case for a car is that you break down on the side of the road (or I guess the brake lines give out).
Worst case for an old unmaintained gas boiler is that your house explodes. I would put the risk of old NPPs with cracks in their 40 year old concrete more on the gas boiler side.
Edit for the downvoters: A properly maintained old gas boiler will probably be fine for longer than its designed lifetime. Also here's some sources for the cracked concrete: https://fanc.fgov.be/nl/dossiers/kerncentrales-belgie/actual...
In light of that, planning for their decommissioning is very sensible I would say.
Are you referencing something specific that isn't bullshit?
https://www.world-nuclear-news.org/Articles/Belgian-outages-...
I believe the downvotes might be from you downplaying the danger of a badly maintained car.
Maybe there just isn't a good analogy for a more than 40 year old NPP.
Maybe an old NPP is just an old NPP.
It's actually a great analogy you make, because what you portray as the "car that at worst might break down" is actually the thing that kills 1,500,000 people every year (yet many people seem to take as just a fact of nature).
https://energy.ec.europa.eu/publications/accelerateeu-energy...
It is not only the oil shock.
Most of the nuclear initiatives at the EU level have been mostly blocked by the German government for the last 15y.
The Russian gas crisis in 2022 reshuffled the cards entirely: Germany realized that constructing its entire energy policy on a foreign asset (Russian Gas) was not really a smart move.
The German position changed significantly after the crisis with Friedrich Merz explicitly called the German nuclear phaseout 'a mistake'.
Soon after, Nuclear energy stopped to be a swear word at EU level and EU funding streams seems to have opened up again for Nuclear power.
The recent oil crisis is just the last nail in the coffin of the anti-nuclear lobby.
They should be adopting every sort of energy.
https://www.nytimes.com/2026/03/13/business/energy-environme...
> For many industrial companies in Europe, high energy costs have been a big concern, especially since Russia’s 2022 invasion of Ukraine. But even before then, electricity, fuels and other forms of energy were consistently much higher in Germany, Italy and other European countries than they are in the United States and China.
Man do I wish that were the case. In any way, we simply don't hold the cards in the EU as much anymore as the rest of the EU has recognized that we're idiots, and they're certainly not keen on joining us in that regard.
The sad thing is, you might be right. With the rise of far right populists everywhere, it is entirely possible that it will be written in the history books just as you said it. It won't matter that it is a lie, as nuclear was destroyed by the conservatives (just like our solar industry, incidentally), not the green party.
Facts don't matter when it comes to nuclear energy, otherwise nobody would pretend that it's "the cheapest form of energy" and the like me
It is not. And people who repeat this lie have generally very little clue of the reality of an electrical grid and how it is designed and managed in practice.
Solar and Wind are cheaper in term of LCOE. LCOE is a secondary metric in a much larger equation.
A grid is managed in term of instant power matching the demand, not in term of energy. That changes a lot over a simplistic LCOE view.
Take into consideration the cost of power lines, the necessity of backup for the long dunkelflaute, the increase of demand over winter and the problem ROI with the overcapacity of solar... and suddenly the equation is not that simple anymore.
In reality, it is not "Just build Wind/Solar + battery Bro": It is much more complex and highly geographically dependent.
(1) A country with a lot of Hydro can generally easy run full renewable with a lot of Wind: Hydro acts as both as storage and a regulation.
(2) A country without much Hydro has a interests to keep the baseload Nuclear. It is mostly CAPEX based and the most economical low CO2 source around.
(3) A sub-tropical / tropical country has all interests to Spawn solar arrays. The air con consumption tend to matches quite well the solar production. At the opposite, Solar is almost an annoyance to the grid in Nordic countries because it produces outside of the peak of consumption and is intermittent.
Like often: there is no silver bullet.
The only part of your sentence what is true, is that indeed 'New nuclear' is way more expensive that it should be. That is however not inevitable, China demonstrate that quite clearly [1].

Get europe off their anti-nuclear, pro gas stance. France gains a fair bit from this development. Russia loses influence as does the mid-east if the trajectory holds.
Winners: heat pump manufacturers, nuclear re-processing, uranium enrichment, eVs, nuclear heavy manufacturers, solar panels (China)...
The problem arises in importing gas from unstable places.
Maybe if you happen to live in a country that primarily uses coal for electricity (up to 400gCO2e/kWh) and you can get cheap oil somewhere, but otherwise you might as well go straight to green energy (whether it glows green or not)
Growing up in the USA, my home town was contaminated with uranium, thorium, and radium due to a nearby uranium processing plant that later became a superfund site. It was in the soil, the water, and sometimes even the air. I knew far too many people who've died of cancers, and I, like many from that area, have thyroid issues from exposure.
Obviously, fuel refining hasn't just carried on like that, in the US and Europe at least. But it's one of many handy cudgels to use whenever folks get excited about nuclear.
All the nuclear waste they've got is stored in temporary places (above ground) at former nuclear reactor sites.
The search is not expected to conclude before 2040 at the very earliest.
Meanwhile I've been filtering the german coal byproducts with my lungs, and paying my electricity 2-3x more per kwh than the french
Do hear the fears that russia could hit a Ukrainian wind turbine with a rocket?
Me neither.
BTW did you also hear that the French government hat to rise the nuclear subsidies because the nuclear energy is so expensive? The prices for consumers were still raised
That's a very dumb point actually, without nuclear Ukraine would be in a much tougher situation energy wise. They're getting their shit fucked regardless, and they seemingly have 15 active reactors producing energy right now, if russians wanted to blow them up they would be long gone.
> BTW did you also hear that the French government hat to rise the nuclear subsidies because the nuclear energy is so expensive?
So what? Energy is a national security matter, electricity is a service, subsidies are fine. Btw these prices are inflated because of European wide electricity schemes (or scams, depending on how you want to see it)
Even if germany got free, unlimited and non polluting electricity right now they'd need 50+ years to make up for how much pollution they released compared to france since ww2
https://en.wikipedia.org/wiki/Radiophobia
Reality, on the other hand, is that nuclear power is what keeps the lights on in Ukraine in this war, and Ukraine is looking to expand.
The ARENH program is not a subsidy, it is, in fact, a reverse subsidy. It requires EDF to sell electricity cheaply to its competitors.
Waste is irrelevant for bombs due to parasitic isotopes. You clearly have zero idea about the topic.
France pays no subsidies(yet, epr2 is another topic). In fact EDF was forced to pay a tax till this year called arenh to subsidize competition. This year that tax was replaced by another tax. Many read the law wrongly about 70eur. It's not that EDF will get guaranteed CFD. It's that EDF will be forced to pay EXTRA tax IF it sells above that limit. French prices dropped both in 2025 and now in 2026. French households have lower prices vs german ones per eurostat.
Basically all your statements are nonsense antinuclear rambling
How can that be, if it's so incredibly difficult that Germany has not managed to do this?
The simple fact is that it has virtually nothing to do with any "difficulty" of finding a repository site, the problems are purely political, same as the US:
"The Government Accountability Office stated that the closure was for political, not technical or safety reasons.[6]" -- https://en.wikipedia.org/wiki/Yucca_Mountain_nuclear_waste_r...
Some German state governments even made this explicit, stating that they would not allow a repository to be designated until the German nuclear exit was finalized in their official coalition agreements.
Another nice little trick was changing the language to require the "best possible" site, rather than a suitable one. Sounds innocuous, but anyone with a bit of experience in algorithms know that in theory, this actually makes the task impossible, because how can you definitively prove that there isn't an even better site that you haven't looked at yet?
In practice it has made the process of finding a site incredibly lengthy, difficult and expensive. It doesn't help that the BASE, the Germany federal agency for nuclear waste has been completely taken over by the Green Party, so there is no interest in actually finding a site, and they spend almost their entire budget every year on spreading anti-nuclear propaganda.
The german government and institutions were (are?) full of pro gas (pro russian/russian tied) people who spend decades in the government before bouncing of to russia to work for petro companies. It's hard enough when you try, so imagine how hard it is if you don't even try
> Gerhard Schröder, who served as Chancellor of Germany from 1998 to 2005, has worked extensively for Russian state-owned energy companies since leaving office.
It just turned out that they weren't careful enough, so now they have got a giant nuclear waste storage pit which is unstable, is trying to leak into the groundwater, needs constant babysitting to prevent it from getting even worse, and will eventually need a nearly-impossible multi-billion-euro cleanup effort. At which point they'll be left with the original waste, plus a large amount of contaminated salt mine material, sitting above ground right where it started.
I reckon they would rather not want a repeat of this.
2. It was an old mine turned into a research mine. It was never intended for actual use.
3. The waste there is mostly medical and low-level other waste like gloves.
4. It is actually safe where it is, moving it is another giant waste of time and money whose sole intent is to stoke fear and create costs.
Most of the waste in asse is from medical and research sectors
Which problems make them considerably hotter - politically - than no-reuse type reactors.
We need EU-level nuclear missiles and we need them fast. We also need EU-level nuclear-powered submarines and maybe carrier groups.
Interestingly the US/UK/USSR dumped loads of nuclear waste in the ocean in the 1950s-70s and I recently read that there was basically no trace detectable of any of it.
And do you know, even if there's no trace today (sufficient dilution), if it also didn't have an impact on the ecosystem in the area at the time?
Pah! We have a lot of those places but excessive federalism has every German state blocking any concrete plan.
I personally live close to a commercial Asbestos dump (an old mine) and absolutely nobody cares about it. It's so unimportant it doesn't even have a Wikipedia article.
Yet the second radioactive waste is concerned (even if it's just old rubble) everybody seems to lose their minds and refuses to even think rational.
So what do you think is going to happen when (not "if") one of those rockets has a malfunction and blows up?
Some was stored underground in the past with bad results because the former mines were unstable.
https://en.wikipedia.org/wiki/Asse_II_mine

It is almost cost-free because in reality, nuclear waste is so low in quantity and so easy/unproblematic to store "temporarily" that it just isn't a real problem. Politicians know this. So they can play this game.
And once pressure builds enough you dig a hole in the ground like you always could have and like the Fins just did and start storing.
Nuclear energy is a God send if managed with extreme care.

Thermal power generation, which is difficult to control, is completely unnecessary in an environment where we have negative electricity prices practically every day from March to October. In Europe, we need rapidly controllable energy sources—obviously more storage capacity.
Due to the many hours during which electricity prices are close to zero, the economically viable full-load hours of a nuclear power plant are reduced to barely 3,000 hours per year, effectively tripling the real levelized cost of electricity (LOCE). In addition to the high costs of nuclear power plants, there is also the enormous expense incurred by the government for military and police security at the facilities.
Since the government prioritizes nuclear power, this leads to heavily manipulated electricity prices, with homeowners with solar panels being among the biggest losers, as they are required to feed electricity into the grid but are effectively paid the full negative prices (usually via weighted average pricing methods)
- the current system based on intermittent renewables is the madness
- it is the intermittent renewables that are difficult to control, not thermal generation
- LCOE, not LOCE.
- Giving priority to intermittent renewables is not a law of nature. In fact it is idiocy that needs to be be stopped.
- Allowing intermittent renewables to externalize the cost of their intermittency to other, stable producers is a huge market distortion
- governments do not prioritize nuclear (yet). They prioritize intermittent renewables
To demolish a functional nuclear power facility is pure lunacy.
Nord Stream, on the other hand...
Obviously that isn't what would happen. The poor would starve whilst the rich still fed cows to eat steak.
True. But if you're working in public policy in a vaguely-democratic country, and trying to get anything useful done - then the public feels vastly more familiar with "giant asteroid wiped out the dinosaurs" than with volcanic winters. So, just like "Zombie Apocalypse (wink)" disaster prep - you go with a "close enough" scenario which lets you achieve some actual preparation.
Hopefully the current energy crisis is a wake up call.
I want everyone to go all in on anything that isn't a fossil fuel. The problem with gatekeeping new energy is upgrading the grid to accomodate wind and solar, and waiting for batteries to be delivered, creates a gap that gets filled with fossil fuels. The pragmatic solution to the energy problem is all of the above; joined with climate change, it's everything above but fossil fuels.
It's not new, it's that PWRs have to be built and operated with that capability (load following), which most nations didn't bother with until pretty recently because it does have a cost in complexity & efficiency. But France has done it that way pretty much the entire time.
> Gas peaker plants currently fill this gap.
Nukes with load following aren't peakers: PWRs can modulate output by 2~5%/minute (depending on their exact design and operating mode) between 30 and 100%. They're not reactive enough to compensate for wind, although they can work with the daily and seasonal patterns of solar pretty well.
The replacement for peakers are mostly batteries (hydro and pumped hydro where that's available but usually where available it's already done)
The EU has north of €1 trillion into new gas infrastructure. That's €1 trillion of commercial interests with a vested interest in negotiating the non-negotiable.
Using fossil fuels for transition is fine, particularly if it's replacing coal with natural gas. But building LNG terminals and installing gas turbines because ding dongs in Dusseldorf got scared of nukes a quarter of a continent away is a great way to raise the continent's energy prices, volatility and carbon continent.
That said, my information is outdated.
Even someone like De Sutter didn't come across as crazy in the European Parliament -- but the German ones, meine Götter!

How is that possible? And what are the consequences?
A significant reason of the “impossibility” of reversing the decision is the regulations around nuclear. Take the problem of micro tears in the concrete. Engie could have maintained the concrete. Because the plant was scheduled for decommission, they did not. So there will be small tears in the concrete. The law does not allow those small tears. Repairing the concrete now is too expensive.
The plant will be owned by the state so now the state has two options: (1) invest a truckload of money to repair the concrete or (2) change the law to allow small tears which have virtually no security consequences anyway.
We all know that the state will choose option (2) but there would be far more opposition if they did so while the plant were owned by a private company that is making profit rather than owned by the state which is operating at a deficit.
Every country should invest massively, nuclear for energy and defense, to eventually protect themselves and solar for energy security.
Bad news: according to the discussions here on HN it appears that there is no consensus on what the good mix of renewable/nuclear is. Therefore us, citizens, will be manipulated by politics.
Especially true now with the explosive growth of data center and AI workloads.
And already-built nuclear is pretty much the cheapest power you can get.
This is about *not* decommissioning working plants.
Both Doel and Tihange have a long, long list of issues.
Compare https://en.wikipedia.org/wiki/Air_pollution#/media/File:How-... with the different energy mixes at https://app.electricitymaps.com/map/. I know which european country's energy mix I'd choose if I could just pick one at will (with the caveat that running flat countries on hydro is not going to work, so that's sadly not ubiquitously available)
Long term, sure, also France has to transition. Uranium isn't infinite. But an existing reactor? Let's save lives and buy time where we can please :|
https://en.wikipedia.org/wiki/Nuclear_power_in_France
Oh, and good chance that in the summer months (when demand is pretty high, especially in the South of France) they may have to shut down again because of a lack of cooling capacity. France was ahead of the game in the 70's, but should have invested a lot more than they did since then. That they installed more than they needed also didn't help, especially not because the energy produced is sold on the open market at a net loss just to keep the reactors operating.
And last but not least: they have an ever growing waste problem.
https://en.wikipedia.org/wiki/Nuclear_waste_management_in_Fr...
The cost of which (besides the maintenance costs mentioned above) has not been accounted for in the electricity pricing. If they did, they'd be running at an even higher loss. Probably the next generation will be presented the bill for that.
I actually did look into that and am familiar with the page, as well as the waste situation, thank you
You've successfully ignored the core point of people are literally dying as we speak from the things we are choosing to continue to do. And not just like five in a mine somewhere, as you would have for solar resources as well, but millions, everywhere, every year
It's so weird to read this moral framework where one puts engineering challenges and a risk of brown-outs over so many lives, especially when you include the 150M ~ 1B people that are expected to be uprooted and become climate migrants 25 years from now if we continue like this
And that’s ignoring all the physical effects of the disaster.
The reactors in question have been shut down by virtue of being too old (1974, 1975, 1982, 1985). Some of them have cracks in the reactor vessels. Maintenance has been lacking. There was also a case of sabotage which was never resolved.
Meanwhile Belgium has a lot of off-shore wind power in the north sea, but lacks battery capacity and transmission lines. Spending money on that would likely be a much better investment.
Nuclear it’s still the densest, most reliable zero-carbon option they have. Keeping the existing plants running (and ideally extending their life properly) is far cheaper and faster than hoping wind + batteries will replace dispatchable power.
At some point reality has to trump ideology.
Belgium seems to be slowly waking up to that. The deficit is real, but blackouts and intermittent electricity production prices are also real — and usually more politically painful.
If I remember well those microfissures were detected with methods nobody else anywhere felt the need to use and were probably there since their construction (and in any similar vat across the world) nor do they pose any realistic big risk.
>Meanwhile Belgium has a lot of off-shore wind power in the north sea, but lacks battery capacity and transmission lines. Spending money on that would likely be a much better investment.
You also know it would be a lot lot more expensive which is why the minister that ran the ordeal mentioned before was instead negotiating for a number of gas plants with decades long profit guarantees.
In fairness, it's not the same gov that nuked the public service than the one in power now. But on the flip side, the selloff of public services to private sector was a success and achieved the stated goals: Destroy it from the inside and use that as an excuse for more liberalization.
can anyone jumpstart me on this, since when is belgium bankrupt?
It's not.
Belgium is rated investment grade by all three agencies [1]. The cost to insure its debt implies a <2% chance of default in the next 5 years [2], lower than America [3]; the IMF assesses its "overall risk of sovereign stress...as moderate" [4].

Belgium is a curious country that was formed via historical quirks around religion (many Flemish/Dutch speaking catholics not wanting to be part of protestant Netherlands, but that is a gross oversimplification and the history is very complex - read up on wikipedia if curious). Historically the Flemish were the poorer part of the country, but after deindustrialization the story flipped as most of the industry was in the French parts. The result is bitterness that holds the whole country back.
Now detail three strengths Belgium posses.
If you hyper focus on the problems, you’ll be completely oblivious to the solutions.

Debt to GDP ratio of 107%, only Greece, Italy, and France are worse. Even Spain and Portugal are better! It is frightening how many member states are over 80% when they are supposed to be at 60% or better.
And my experience is only with Flanders which is basically one large city, I can only imagine how it is in the less populated areas of Wallonia or Limburg.
But I absolutely think that nuclear is a good option for such a small and dense country. Taking over the plants as they are nearly decommissioned is a stupid move though, but you can't expect anything sensible from this government.
I do take the train quite often as I said, anything on large axes is usually fine (Brussels - Charleroi, Brussels - Antwerp, etc) but yeah smaller lines are usually struggling some more.
I wish we had more ambitious governments in general, not only in terms of energy but also in the (bio)tech scene, which used to be touted as our great strength (we do have a lot of pharma companies though).
Running ancient nuclear power plants in one of the most densely populated countries does not seem wise.
These plants have been running with phase-out in mind for the last 20 years.
Meanwhile the prices dropped further than ever, 20kW peak with 20kWh batteries for EUR 10k, which provides >95% self-sufficiency in a 2p Household and lets you sell more than 80% of the yield (though prices are already very low when the sun is shining). And this is without an EV yet. Please enlighten me: Why are we still having these discussions? I don't see why that wouldn't scale in the US as well, what's the status with flexible energy pricing?
If anything, we need to build fast, flexible power plants, but their lobby groups are well oiled already without our support.
And what are those?
But but solar had a 90% reduction in cost between 2010 and 2026, and is projected to decrease between 50% to 80% again by 2035. So once again, it's just numbers, and some people are being emotional again. Further evidence is that China added 70x as much solar as it did nuclear in 2025.
> "This government chooses safe, affordable, and sustainable energy. With less dependence on fossil imports and more control over our own supply," he wrote on X.
Really? So nuclear power plants are suddenly the new "clean" hype? Because if Belgium is stating "more control over our own supply", can we mention a little something THAT BELGIUM HAS TO IMPORT URANIUM? So the "own supply" here is ... what exactly? Besides, I question the "nuclear is now clean" campaign that Leyen is doing. She is the ultimate lobbyist. It is also strange how the EU says "russian energy is bad", but then is silent when uranium is imported into the EU from Russia. We are here being lied to by these lobbyists/politicians. And a few make a lot of money, at the expense of the great majority. Why were renewables barely strategically expanded? China did so. Why are democracies so incompetent nowadays?
Maybe something changed in 2024 because [2] "Belgian nuclear plants no longer run on uranium from Russia". It ends with "Engie does not disclose how many different contracts were concluded and with which suppliers, but does say it obtained a sufficient geographical spread of its supply, Belga News Agency reports." So who knows.

Say, sorting thrash. EU new idea is to make Europeans to sort thrash into 12 separate beans. So what that all trash goes through sorting process before being dumped, and there are very modern and efficient sorting robots that use AI, etc. that can do sorting much better than any human.
So, maybe, just maybe it is better to invest more into new technologies, instead of turning Europeans into wastes sorting machines.
And this is only one more example where EU countries are doing something plain idiotic, nevertheless, like in the great Buñuel's movie "The Exterminating Angel", nobody is able to admit that there is something stupid going on and it is enough to open the doors and walk away.
Short answer: Russians and Germans. The former had influence in the latter. And the latter gained a measure of economic command over the continent. (With its export and energy model under shock, that influence is near its post-unification nadir right now.)
I'm glossing over anti-nuclear national politics, as well as the genuine fiscal pressure of capex-heavy power sources like nukes (versus opex-heavy ones like gas). But broadly speaking, take Russian influence in Germany out of the picture, or have one other large fiscally responsible economy going into the Eurozone crisis, and I doubt this would have happened.
I would be more worried about the fact that a lot of the garbage that first gets separated ends up getting burned anyway because recycling is not even possible in a lot of cases.
Do you have a source for this, or are you just making things up?
So the stuff they collect doesn't need 12 different kinds of bags/bins, and the (financial) incentives are correctly aligned. I think it's a good system and pretty convenient, but I'd wish they recycle & process the waste even better afterwards. But the hardest part – getting the population on board – seems to be well-established.
Recycling is difficult, some materials are relatively easy (aluminium cans, steel), some not so much (plastics f.e. tend to degrade, some materials are energy intensive to recover). Contaminants are a major issue that still need more public awareness. But we're going in the right direction.
Lets hope we see less policy which is at a very small step back basically: "we're competing to punch ourselves in the face the hardest" in the international arena.
One bug could lead to severe damage to everything and everyone around a nuclear power plant. We see those kind of bugs on the front page daily.
In my opinion it is absolutely irresponsible to start them up in the first. I have seen too much to actually trust in people always getting their shit right.
