Believing we're in a climate crisis and also being anti-nuclear are mutually exclusive positions in my mind, and opposition to nuclear from environmentalist orgs should be viewed as a massive historical mistake as it set us back decades in moving the needle on carbon emissions.

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!

avianlyric1 day ago
They have done. The Three Mile Island accident happened when it was being operated by Navy vets [1]. Simple training isn’t enough.

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.

How many people have died on account of nuclear accidents?

Vs. coal?

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

> 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?

The Three Mile Island accident is also dramatically exaggerated in the public conscience with its severity and risk factor - solely because of the default fear of Nuclear.

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?

Would it be fair to say that because the US Navy is not running it as a for-profit power generation that would help. Like every accident seems to be a list of cost saving shortcuts being responsible

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...

They're expensive because of, arguably, over regulation. The are not inherently expensive, we've just declared them so.

The engineering side might be a theoretically solved problem, anybody looking at belgium's crumbling nuclear powerplants can help but feeling slightly nervous!

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.

Nuclear waste is small and solid

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:

I know it's not a green ooze. But thinking it is possible to store something safely for >10000 years is just wishful thinking. The waste is a lot more dangerous than the uranium we dug out and packaging it in a way where you are sure it won't surface for sure is really not a solved problem.

> Nuclear waste is small and solid

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.

If you believe in a climate crisis and are serious about it you probably want to run the numbers on different options and policies to see what works rather than saying yay this boo that. Running numbers on producing energy in say 15 years time which is roughly how long it takes to approve and build nuclear, and comparing it with projected solar+wind+battery costs for 15 years hence you tend to come with much better figures for the non nuclear. (see graph here with the trend https://www.noahpinion.blog/p/nuclear-vs-solar?hide_intro_po...)

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_...)

xphosabout 20 hours ago
We can both build Nuclear that is safe and also build it faster. Its a matter of political will and reasonable regulation. Nations looking on the 100 year horizon would build nuclear and they would be newer and safer nuclear as time goes on. The next generation of reactors are safer and promise to be cheaper to build but the last of the GEN4 nuclear still are safe especially when we actually pay to have nuclear regulator inspectors. The things we are willing to be cheaper on are always the inspectors but never the permitting its so backwards.
audunwabout 12 hours ago
I don’t see why you would look at nuclear at all on a 100 year horizon. At that timescales you gotta look at the fundamentals:

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.

For China, nuclear power plants are still not very important, they build a lot new coal power plants.

The reason why people tend to get a bit cheerleadery about nuclear power is because it has some great PR and it resonates with them.

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.

Wind and solar power are remarkably stable in Europe. Last year, the average weekly electricity output was 14.0TWh; not a single week fell below 10.5 TWh.

Weather fronts move across the continent on a very regular basis; when the wind dies down, the sun shines more.

Mind that nuclear power relies on favorable weather as well. It's not uncommon in Europe that nuclear power plants have to shut down, because the rivers they use for cooling become too hot.

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.

Burning coal in coal power plants causes more deaths each year in Europe than the total deaths caused by Chernobyl accident (4000-8000).

Serious question, when has there been a serious nuclear accident? Fukushima was caused by a natural disaster that killed far more people than the nuclear failure did. Chernobyl was pure communist stupidity. This level of incompetence would never happen in a well functioning country. So that leaves Three Mile island?

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.

Nonsense, the reluctance of governments to reduce carbon emissions has been driven by the reluctance for entrenched industries to give up their gravy train. There are many ways for power to be produced with lower carbon emissions, it's absolutely not a binary situation at all.

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.

belorn1 day ago
I would be very happy if people who oppose nuclear would abstain from supporting the fossil fuel industry. When EU voted on green technology, one side voted for nuclear to be defined as green, while the other side voted for natural gas to be given the green status.

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.

taegeeabout 21 hours ago
> Why are they unmanageable?

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.

Sure, someone can be both concerned about climate change and oppose nuclear power. But it's a largely self-defeating stance: nuclear is the only non-intermittent geographically independent form of clean energy. Dams and geothermal are geographically constrained.

Small thing, dams are not carbon neutral. Depending on location, the plant life they inundate no longer absorbs carbon and, worse yet, the rotting plant life emits methane and other not-good gasses.
tialaramex1 day ago
Nuclear is also in practice significantly geographically dependent.

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.

Why do so many nuclear fans try to suggest climate change only exists if you like nuclear? It's very odd.

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?

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?"

jltsiren1 day ago
That's not an apples-to-apples comparison. Naval reactors look cheap, because the cost is for the reactor in the narrow sense. Other major costs, such as the containment building and countermeasures against natural disasters and terrorist attacks, are included in the costs for the rest of the ship.

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.

There's two very different types of reactors: the already-paid-for long-run reactor that's still going, and then on-paper-not-yet-constructed reactor in a high cost of living nation.

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.

simplyluke1 day ago
> The far bigger fight for climate these days isn't electricity: it's car-centric living

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.

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.

epistasis1 day ago

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.

dalyons1 day ago
naw, we'll just build enough battery to cover the nights and then use gas as emergency backup for any rare wonky weather events. that could easily get us to 90+% clean, which would be absolutely amazing. Constant base load only supply like nukes are economically obsolete. On a modern grid you need a rapid response backup. Which is gas for now, and hopefully we'll come up with something to replace that later.

Even with Danish insulation and weather and tilting the study heavily towards nuclear power by assuming that the nuclear costs are 40% lower than Flamanville 3 and 70% lower than Hinkley Point C while modeling solar as 20% more expensive renewables come out to vastly cheaper when doing system analyses.

That's great, but we live in the 2020s, not the 1970s. Technology has changed over 50 years. France talks about building more nuclear, but what's actually getting put on the grid is renewables, not nuclear.

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.

A bit unrelated to the Belgium story but I recently visited Diablo Canyon Nuclear Power Plant near San Luis Obispo, CA and learned a ton about the technical details, safety systems, and policy decisions that go into operating a nuclear power plant. When operating at full capacity, it provides up to 10% of California power! While there is certainly always more such facilities can do for safety and efficiency, my impression is that smart people are working hard to ensure the lessons of previous disasters and potential future ones are mitigated, and that nuclear energy, whether through next-gen small module reactors or legacy systems, will be an important aspect of our future energy grid, especially with the rapidly rising energy demand predicted over the next two decades.

I did some research about that nuclear power plant. In 1985 dollars, the total construction cost was 5.6B USD. That is an astonishing amount of money. That is at least 16B USD in 2026 money. If you also include decomissioning costs of about 4-5B USD... how the fuck does nuclear power make any economic sense? PV solar plus batteries: ALL THE WAY. To be clear, I am not anti-nuclear power by any means. I think it is a terrific way to power our countries, but the ship has sailed. PV solar has won, and now we can add batteries (and some wind) to get reliability.
booi1 day ago
$5.6B actually sounds like a good deal. It outputs 2GW+ of power. While solar is definitely cheaper for 2GW of power, you still need batteries for when the sun is down. So you probably need approximately 30GWh of batteries to just replace this one power plant. The batteries alone would cost nearly $7B of grid-scale batteries that must be replaced every 20 years.

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).

boznz1 day ago
Due to increased regulation etc you cannot just translate 1985 $, £ or Euro to a 2026 one. There is an actual example in the UK Hinkley Point C current estimate $43b, (£35b) where as sizewell B commissioned in 1987 was $3.2b billion (£2b) or about $7b in todays $.

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.

It makes economic sense because they require a large initial investment (CAPEX), but low cost per year to keep functioning for many decades (OPEX). In contrast to say wind or solar, which are smaller CAPEX but higher OPEX.

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.

laurencerowe1 day ago
Unfortunately France can no longer build nuclear plants cheaply either. All of the recent nuclear plants built by the French state owned company EDF in France, Finland, and the UK have seen enormous cost and time overruns.

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.

Manuel_D1 day ago
It's a large amount of money, but the plants have a long service life. And once a nuclear plant is built, it's operational costs are much lower than other forms of electricity generation.

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.

rayiner1 day ago
It’s not a choice between nuclear and PV. It’s a choice between nuclear and the other things that provide base load: gas and coal.
NoLinkToMe1 day ago
Or solar / wind (which mostly anticorrelate) + biomass + storage + interconnectors + smart demand.

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.

jillesvangurp1 day ago
The issue with "base load" is that people usually omit to mention how much GW they are talking about and for how long. Which makes it a bit of a bull shit argument.

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.

dv_dt1 day ago
A requirement for base load is a fallacy promulgated by fossil fuel preservation lobbying
dalyons1 day ago
it actually is a choice between nuclear and PV, because base load supply is an obsolete concept. Because actually nuclear is terrible in a grid increasingly full of nearly-free variable sources (solar&wind). The nukes need to stay at 100% all the time selling their power at a high fixed price to have any remote chance of being economical. Cheap variables push nuke's expensive power off the grid during the day, and increasingly into the evenings with batteries. This is unavoidable in an open energy market, and is fatal to the economics of nuclear. You cannot make them work without massive state subsidies.

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.

It was not a good idea for Germany (and certain other parts of the EU) to be so dependent on Russian gas. It was also not a good idea to become dependent on LNG from Qatar or the US.

Not because Norway is likely to turn on us (or we on them), but because the pipelines are relatively easy to disrupt.

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.

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.

To use the strongest plausible interpretation, the writer could be from Belgium, where the meaning of 2.256 depends on whether they wrote the number in French, Dutch or German.

The Belgians apparently typically invert the meaning of . and , in numbers (from how they are used in the US).

  To make large numbers readable, Belgians use either a period (.) or a non-breaking space. Example: Two thousand thirty-six is written as 2.036 or 2 036. In formal Belgian French, the space is increasingly preferred over the period to avoid confusion with the Anglo-American system, but the period remains very common in Belgian Dutch and everyday shorthand.
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.

mount signal, the largest PV plant in california makes 1,200GW/hrs per year. it would still take ~15 copies of mount signal for a single diablo canyon https://en.wikipedia.org/wiki/Mount_Signal_Solar

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

> diablo canyon has 2 reactors that can make 1.1MW per hour continuously

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).

WaxProlix1 day ago
There is so much misinformation in here, so densely packed.

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).

Strictly: France will no longer decommission Belgium's nuclear power plants, as Belgium will buy them. The current owner Engie are majority-owned by the French government.

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.

leonidasrup2 days ago
Nuclear reactors are regularly maintained, tested and checked. When possible, old plants are upgraded to new safety standards.

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...

The claim that disasters happen to older plants is not refuted by the observation that lessons learned are applied to the whole fleet.

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.

cogman102 days ago
Fukushima. It was a Gen 1 plant which already has the issue that a thermal runaway is possible. There were other examples of this happening like TMI. The backup for Fukushima was onsite generators which were flooded and ultimately failed causing the meltdown.

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.

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.

Heartening to see someone talking about both the pros and cons. I find here and on, for example reddit or twitter, that people are unanimously in favour of Nuclear.

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.

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.

I'm no expert but I believe the problem there is that you can only vary the power output of a nuclear reactor by very little. Essentially, it's either on or off, and is therefore not able to provide the flexibility needed for power outages, since only some of the generators might be offline, not necessarily all of them. Whereas you can vary the output of a coal or gas plant by a lot, simply via using different amounts of fuel.

But renewables and batteries make this so much worse, specially once you talk about long distance renewable.

crote2 days ago
Nuclear isn't an economically viable option for base load. Nuclear is the most expensive form of power generation. If there is excess supply, forcefully turning off renewables to buy electricity from nuclear would make the electricity needlessly expensive and kill the free market. In other words: it can only be a base load if we massively subsidize it and throw away free renewable electricity.

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.

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.

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.

crote2 days ago
> it's a terrible idea to phase out operating nuclear plants which are still safe and within their planned lifetime

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.

You'd likely do less harm if you just dumped that waste in a heap on a roadside than if you shut down the plants and as a result ended up with more coal plans continuing to run.

Maybe hydro - with a very big caveat that the big risk with hydro is dam failures, which are rare, but can be absolutely devastating when they happen.

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".

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.

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.

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].

Gas is an excellent compliment for renewables. It scales up and down quickly, and can cover all the weak spots around intermittency and dunkelflautes. The carbon emissions are relatively low too, because in renewables/battery heavy grid the actual quantity of gas needed is relatively small.

The problem arises in importing gas from unstable places.

Everyone focuses on the safety of power production, and I totally get that and think it's important, but the mining and enrichment of uranium should also be considered. Nuclear "disasters" aren't just 3 Mile Island, Chernobyl, and Fukushima. There are plenty of other disasters that aren't power plants.

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.

There are a small number of such sites in the US. One that fits closely with this description is a legacy of the Manhattan Project: Coldwater Creek, MO.

Interesting fact: Finland just built one, for €1 billion.

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.

boshomi1 day ago
Nuclear energy is pure economic madness in a context where wind and solar power are generating a surplus of electricity. Today, May 1, electricity prices in Europe are in some cases at the technical minimum of minus €500/MWh.

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)

mpweiherabout 18 hours ago
The opposite is true.

- 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

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.

elric2 days ago
IIRC those old Belgian reactors got in the way of more renewables for some time. They provided a very cheap base load that seemed hard to modulate, which meant that even cheap renewables couldn't really compete on price. If I understand correctly, newer nukes can more easily modulate their output, which would be useful at night or on days without wind etc. Gas peaker plants currently fill this gap.

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)

Depending on the country's situation, you might have to use fossil fuels during the transition, that's alright. But the transition is non-negotiable at this point.

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.

Compared to other countries I've lived in, Belgium doesn't do too bad of a job in promoting 'green energy'. Although I've not lived there for some years, they used to subsidize things like solar panels on roofs (at least when my parents installed them 20-ish years ago). And there are 'green energy' companies as far as I'm aware, so you don't have to stick with the larger energy providers.

That said, my information is outdated.

the choice here was nuclear or new gas from engie
skerit2 days ago
For years, even leading up to starting the decommission of the power plants, Engie has been saying it's literally impossible to reverse the decision. And now that we're 2 years into the decommission, suddenly it is possible after all.

How is that possible? And what are the consequences?

IMTDb1 day ago
They said it was impossible for them to reverse the decision. Nothing has changed; they won’t be in charge of that. The state will.

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.

ineedasername1 day ago
Decommissioning always seemed odd absent either specific dangers or higher costs of operating than renewables. For new construction of course the costs shift dramatically, but existing plants that can continue to run would seem to provide exactly the legroom that enables more rapid expansion of renewables. Less time spent backfilling and exposure to both market and geopolitical forces of other energy sources, eg when there are disruptions of the sort going on now.

Almost everybody that trumpets how fantastic France is doing with their nuclear fleet has no clue how they are really doing. You can start here:

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.

This doesn't seem like a terribly great idea, for several reasons. Belgium is nearly bankrupt, with a government deficit that the EU is already giving us grief for, in spite of some of the highest tax rates in the world. That same government hasn't exactly managed any of its semi-public companies particularly well: the national telco is for shit, postal service is nearly bankrupt, railways are mismanaged and underfunded, etc.

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.

enricotal2 days ago
Belgium’s government might not be in its best shape. But still the logical conclusion in my humble opinion isn’t “let’s shutting down the one power source that actually works.”

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.

modo_mario2 days ago

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.

Bankrupt is a politically loaded term, but they have very high debt and taxes, political gridlock (it is very divided among French and Flemish linguistic lines, plus all the other traditional left/right polarization), and it is all but impossible to make reforms. IIRC there was no sitting government for 500 days at some point. It's also got all the classic problems of an aging population.

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.

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.

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.

Really? So nuclear power plants are suddenly the new "clean" hype?

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.

The most important question is: who the hell decided to do such a stupid thing and in the name of what. When we have an answer maybe we can look on other ideas the same people figured out and also rethink them.

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.

> most important question is: who the hell decided to do such a stupid thing and in the name of what

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.

Sorting machines are in fact used in these countries. But most of the trash separating efforts were introduced many decades ago, long before the capabilities of modern AI systems.

Where I live (Belgium) waste collectors pick up "rest" waste in relatively expensive trash bags weekly, PMD (plastic/metal/drink cartons) weekly, compostable waste every two weeks, cardboard monthly, and glass also monthly. Certain things we have to bring ourselves to a collection point (batteries) or recycling park where everything gets sorted even more specifically. I tend to go to the recycling park once every two or three months, the rest gets collected at home.

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.
