I feel the same way as well. It would make sense for an oil rich country that feels threatened by people not buying oil (or gas) to subvert a movement like greenpeace.
So, it didnt attract any hate or shaming from the nuclear industry's faux - environmentalist public relations arm. Unlike Germany, whom they really hate and for whom the FUD and lies was nearly constant.
(E.g. https://www.reuters.com/article/business/energy/german-nucle... remember when the nuclear industry-promised blackouts finally materialized? I dont).
While I agree that nuclear is green, IMO Greenpeace are correct about it not being compatible with the "peace" half: the stuff that makes working reactors is the most difficult part of making a working weapons.
This also means that during the cold war they suspected of being soviet plants.
Those suspicions and yours could both be correct for all I know.
I'm unaware of this to be true. Civilian reactors are hardly-at-all-enirched uranium reactors. Creating highly enriched uranium or plutonium are completely different processes.
I don't have sources and would appreciate if anyone has anything to offer on this.
The LCOE (Levelized Cost of Electricity) for solar with battery is already better than current solutions, and dropping. Wind and battery closely following. There is no way that nuclear technology will be able to compete on price in the foreseeable future.
In each case it's pretty obvious. Either they have nuclear weapons that share a supply chain and skills base or there is an existential threat out there.
In Poland's case you can tell when they started seeing an existential threat from when they suddenly got interested in building a plant.
Not an expert, but isn't all you basically need to do is running the centrifuges a bit longer?
Breeding plutonium is a different process than enriching uranium, sure, but with enough enriched uran you will have a nuclear bomb.
And a dirty bomb is bad enough and simple to construct as well.
lol at wind though. that's not real.
However, it's likely that Greenpeace benefits from indirect support from the fossil fuel industry and petrostates. If you get too deep into Realpolitik, you start believing that ideologies and convictions only hinder and weaken you. Then it becomes acceptable to support groups that are ideologically opposed to you, as long as it advances your strategic interests. There have always been ways of manipulating the public sentiment, and social media has made it easier to do that without linking the manipulation back to you.
LCOE is not a fundamental metric. EROI is and it's pretty bad for photovoltaics.
Like the guy you're responding to, I'm not a nuclear hater. We also have other "limitless clean energy sources" however, wind and solar.
How is nuclear going to benefit humanity in ways electrical energy hasn't already? We haven't been energy constrained in the past 10-20 years. It really doesn't seem like additional energy production is going to make that much of a difference.
Obviously there are such things as "breeder reactors" that are deliberately designed for this. But there's really no such thing as a can't-be-used-for-bombs reactor.
It's the same dynamic that gets people to earnestly and fervently believe in, say, they're infested with Body Thetans or that the local cult leader is Jesus or (as Pythagoras believed) eating beans (yes, the food) is sinful. The belief becomes a tenet of the group, a reason for its existence and a prerequisite for membership. Evaporative cooling fixes the belief by ejecting anyone who rejects it.
Greenpeace will never accept nuclear power. Opposing it is part of their core identity and anyone who disagrees leaves. Greenpeace the organization can be defeated, but it cannot be reformed.
For China which has the mineral it probably doesn’t make sense but for Europe, nuclear is a solid alternative especially when you consider that you can probably significantly extend the life time of the already existing power plants. Even if we ultimately transition to something else, it’s better than coal and gas in the meantime.
First, solar and wind are massively subsidized pretty much everywhere they are deployed, in addition to the indirect subsidies they get from China subsidizing production (and internal deployments).
Second, and more importantly, LCOE is not the full cost, as you rightly point out. It leaves out system costs, and these are huge for intermittent renewables, and not constant. They rise disproportionately as the percentage of intern mitten renewables in a particular grid rises towards 100%.
Third, and related, in most countries where renewables are deployed, intermittent renewables not just do not have to carry the burden of their intermittency, they are actually allowed to pass these burdens and costs onto their reliable competitors. Which is even more insane than not accounting for intermittency.
A decentralized grid sound way more resilient, then one with a few nuclear plants, which often have long unexpected downtimes (see France). I agree with you on the potential logistical dependencies, however that sadly applies to nearly everything right now.
Running our own fusion reactors would be great but waste is not limited to fission designs. All nuclear generation has radioactive waste, it’s unavoidable.
Grid scale storage with renewables can absolutely meet our needs.
System costs may be high, but they are on a downward trend due to the increasing implementation of grid batteries, which also solves the third argument.
Technically, a grid based on nuclear production is also a distributed grid. You have multiple plants and it’s easy to add overcapacity to the grid because nuclear is easy to modulate.
I watched a very interesting documentary about Onkalo, which happens to be on YouTube: https://www.youtube.com/watch?v=ayLxB9fV2y4
If you're going for the U233 (from Th) or Pu route, yes then you need a reactor and spent fuel reprocessing. But not enrichment of spent fuel.
Not everyone has a U mine or pre-existing bomb industry. The question is whether or not having a reactor makes producing bombs easier or not, and clearly the answer is "yes", bomb-making is easier (yet, sure, still a "PITA") if you have a reactor core handy to start with.
None of this happens to be true.
A single nuclear power plant is big and complex, but the amount of electricity it produces is so much more than renewables that this difference vastly overshadows the first one.
Last I checked, resource use and land use are at least 10x less. And of course production is actually the smaller part of the cost of electricity, transmission (the grid) is actually the bigger part (60/40). This gets several times more expensive with intermittent renewables.
Making the more expensive part of a system several times more expensive to at best save a little bit on the cheaper part seems...foolish. It's like the old Murphy's law "a $300 picture tube will blow to protect a 3¢ fuse" translated into energy policy.
And whether LCOE is actually cheaper with intermittent renewables is at best debatable. Factor in system costs and it is no contest. Intermittent renewables today generally only survive with massive subsidies both in production and deployment, with preferential treatment that allows them to pass on the costs of intermittency to the reliable producers and last not least fairly low grid penetration.
What happens when you have more than 80% intermittent renewables in a grid we could observe in Spain. Since the #Spainout, the grid operator put the grid in "safe mode", which means no more than 60% intermittent renewables. Quick quiz: if that is "safe mode", what does that make >60% intermittent renewables?
Here the Finnish environment minister:
""If we consider the [consumption] growth figures, the question isn't whether it's wind or nuclear power. We need both," Mykkänen said at a press conference on Tuesday morning.
He added that Finland's newest nuclear reactor, Olkiluoto 3, enabled the expansion of the country's wind power infrastructure. Nuclear power, he said, is needed to counterbalance output fluctuations of wind turbines."
Which brings us to adjustability: intermittent renewables are intermittent, you are completely weather-dependent and cannot follow demand at all. It is purely supply side. Or have you tried ramping up your PV output at night on demand? Good luck with that.
While no energy source is completely safe, nuclear happens to be safest one we have.
This only leaves "Dunkelflaute" as a concern, which can be solved with either hydrogen/gas etc. production and storage during peaks in the summer for example.
Those extra steps are crucial, as they massively dilute the output and make it weather/daylight and seasonally dependent.
Intermittent renewables produce at least an order of magnitude more waste than nuclear reactors, be they fusion or fission.
That is also not true. For example in Germany, nuclear production was never subsidized at all. Even Greenpeace and the Green's chief anti-nuclear Lobbyist, Jürgen Trittin, called nuclear power plants "money printing machines".
> Be it through state sponsored loans or tax breaks (France)
Those are minute compared to subsidies intermittent renewables get in Germany. In particular as there is the ARENH program, which is effectively a negative subsidy (it takes money away from the nuclear company EDF), and of course EDF is profitable and gives money to the government.
When you add it all up, France has a negative subsidy of € 0.1 - 7 billion yearly, whereas Germany subsidizes intermittent renewables to the tune of around €20 billion a year.
> System costs may be high, but they are on a downward trend
That is also not true. System costs are actually rising, because yields are dropping, the share of renewables has risen and the (fairly cheap) coal backup is to be eliminated. Total costs are now estimated at several trillion euros. For comparison, France's nuclear program cost a total of €228 billion through 2011.
>…The share of electricity produced with fossil fuels in Germany increased by ten percent between January and the end of June 2025, compared to the same period one year before, while power production from renewables declined by almost six percent, the country’s statistical office
>… Coal-fired power production increased 9.3 percent, while electricity production from fossil gas increased by 11.6 percent.
https://www.cleanenergywire.org/news/fossil-electricity-prod...
The direct deaths caused by burning coal are significant. I didn’t see any current estimates for those being killed downwind from Germany's reckless burning of coal, but overall the EU has a high death rate:
>…Europe, coal kills around 23,300 people per year and the estimated economic costs of the health consequences from coal burning is about US $70 billion per year, with 250,600 life years lost.
https://www.sciencedirect.com/science/article/pii/S030147972...
Never mind that all those coal plants are also contributing to climate change and are poisoning the oceans enough that many species of fish are not safe to eat. The waste problem from coal will also be a problem for future generations to deal with - not all the ash from burning coal is being deposited in people's lungs.
In 2023, I saw a stat that in 2023 about 17.0% of Germany electrical production was from burning coal. As a comparison, I believe that before the phase out of nuclear power, it generated about 25% of the electricity.
If Germany wanted to shut down nuclear power plants after they had decarbonized their grid, that would be their choice - shutting them down when you are still burning coal is almost unbelievable. I don’t think future generations will look kindly on countries who shut down a clean form of power while they still are running the most dangerous and dirty form of power generation ever created.
EDF was nationalized in 2022, doesn't have to build money reserves for decommissioning (which would be tens of billions), is about 50 billion in debt and just got a 5 billion government loan to keep some old reactors running and another government loan to build new plants. These are not minute interventions, both France and Germany heavily subsidize their sectors (in different ways). With the ARENH program ending in 2025, a more fair comparison will be possible.
I have to read up on the system costs though, that may be ai fair point.

Spain has far too little transnational capacities. That was a significant contributing factor in the grid outage.
That's not true. That report is based on a completely ridiculous paper by the FÖS, the "Forum Ökologisch-Soziale Marktwirtschaft". Calling the numbers it uses "completely made up" is putting it kindly.
One of the many debunking is here:
https://kernd.de/wp-content/uploads/2023/05/Artikel_atw_D_20...
Summary:
"The disregard for scientific methodology, for basic knowledge of economics and business administration, environmental economics, energy economics, and nuclear technology, the biased selection of sources, even the use of newspaper articles as supposedly scientific sources, and the denial of the positive effects of nuclear energy, which far outweigh its social costs, are unworthy of the FÖS. Either they are a sign of insufficient economic expertise at the institute, as well as a lack of knowledge of scientific methodology, or the FÖS is deliberately misleading readers with the aim of being able to cite the highest possible fictitious costs for nuclear energy on behalf of its NGO clients. Both discredit the study and its client."
The debt that EDF carries is completely normal for a company this size, especially one that does infrastructure. It would be unusual for a company not to use the capital markets to finance such projects. EDF has been highly profitable for decades, recently while being used to subsidize other parts of the economy via ARENH as well as being used to buffer the effects of the energy crisis, not just via ARENH, but through massive expansion of ARENH.
ARENH is not "ending", it is being replaced by a comparable scheme that is structured slightly differently.
EDF was not "nationalized" in 2022. It was always a state company, with the state never holding less than 85%. The period where the state held less than 100% was relatively short, from 2005 to 2022. The state bought out the minority shareholders in order to streamline the planned nuclear expansion.
The "subsidies" for EDF (cheaper loans etc.) amount to around € 2.7 - 3 billion a year. By itself, that's obviously not "minute". However, these sums are dwarfed by the ARENH program and the profits that EDF pays to the state, which turn the subsidies into "negative subsidies" in sum. That is, the state gets more money from EDF than it gives it, by a good amount.
Even if that weren't the case, the sums are dwarfed by the German subsidies for renewable, which are an order of magnitude higher than the gross subsidies in France (and infinitely higher than the net-negative subsidies).
It takes 10-20 years to build a new nuclear plant, if the goal is decorbanize the grid, then nuclear is to complex and slow.
> Last I checked, resource use and land use are at least 10x less.
True, but land use just isn't that important of a factor. Especially if roofs and other unused lands come into play. It just doesn't make much of a difference.
> (the grid) is actually the bigger part (60/40). This gets several times more expensive with intermittent renewables.
With the electrification of cars and so on, the grid has to be modernized no matter what.
> Intermittent renewables today generally only survive with massive subsidies both in production and deployment
Most of the time nuclear also doesn't pay for decommissioning and nuclear waste etc. by itself. At the same time a lot of renewable projects right now are also profitable without subsidize and this will apply to most in the near future. Especially when batteries become more widespread.
> What happens when you have more than 80% intermittent renewables in a grid we could observe in Spain.
The Blackout in Spain had nothing to do with renewables but happened due to a faulty substation.
> [...] Which brings us to adjustability: intermittent renewables are intermittent, you are completely weather-dependent and cannot follow demand at all. It is purely supply side. Or have you tried ramping up your PV output at night on demand? Good luck with that.
Grid scale batteries solve this problem.
Except financing research and development, guaranteeing loans to reduce default risk and interest rates, capping liabilities to enable insureability at lower rates by guaranteeing to fix damages in case of critical failures with public money, financing and organizing emergency civil protection measures, as well as waste disposal, granting massive tax cuts, doing the diplomatic leg work to import uranium and protecting its transport with the police, all and all summing up public spending on making nuclear energy in germany to 169,4 billion euros according to the scientific service of the Bundestag (Document Number WD 5 - 3000 - 090/21), with the more green leaning FOES calculating 304 billion. And on top of that it is estimated that another 100 billion in public money will be needed to fix up long term waste disposal sites morsleben and asse.
... well except from those few hundred billion euros they barely ever subsidize it at all.
I neither said nor implied that the green transition is complete. Green transitions take decades. Germany is merely transitioning the fastest and doing it without the overpriced and risky albatross that is nuclear power.
>shutting them down when you are still burning coal is almost unbelievable
It's unbelievable that the country some people are most furious at is the one that has decarbonized at the fastest rate.
Not the country next door to it that didnt even try.
They are seemingly obsessed with what was once ~8-12% of Germany's power output, but the actual environment? Not that important.
It's bizarre.
And you need nuclear reactors to make plutonium. The weapons you can make with plutonium are qualitatively different from the ones you can make with uranium.
Bit of a rush to close the GitHub ticket eh?
Maybe you didn't intend too, but your words certainly implied it:
>>...it didnt prove conclusively that you could decarbonize your electric grid without any help at all from nuclear power.
Since you reference Germany later, the implication above was that Germany did prove you could decarbonize your electric grid without any help at all from nuclear power. Which might be true someday in the future, but Germany certainly hasn't decarbonized their grid yet. The one thing that Germany did "prove conclusively" is that thousands of lives were needlessly lost over the last 15 years because of bad policy.
>Germany is merely transitioning the fastest
Germany will certainly not be carbon neutral the fastest. I guess it will beat Poland though.
>Not the country next door to it that didnt even try.
You have a point - it is the responsibility of every country to decarbonize. I guess a big issue here is simply money - Poland GDP is much smaller than Germany and they have less available options. Though besides your claim, I've never heard anyone actually lauding Poland's efforts or thinking it was a good thing they are using coal.
>...They are seemingly obsessed with what was once ~8-12% of Germany's power output, but the actual environment? Not that important.
I have no idea what you are trying to say here.
Like I said, I find that those who actually want to decarbonize the grid, don't particularly care what clean technology is used and different countries will have a different mix of technologies they use. Unfortunately, there certainly do seem to be some advocates of solar/wind who would prefer to go decades (or maybe much longer) burning coal and killing people and destroying the environment when their country had the option to use a clean energy source.
And depending on how you look at it, it could be 100,000 years before you know for sure if it works, so my claim that it’s a ‘solved problem’ is a bit strong. I’ll retract that and say that it’s the most promising idea for nuclear waste disposal, one that that is close to beginning operations.

This, again, is not true. The average is currently at 6.5 years and dropping slightly, the time has been fairly consistent over the last decades.
https://www.sustainabilitybynumbers.com/p/nuclear-constructi...
The main factor determining build times appears to be "how much do you want to?". France built 50+ reactors in a total of 15 years, the fastest build times are Japan, South Korea, China and Germany.
Secondary factors are "is this a FOAK build or NOAK", and "how much experience is there building nuclear plants". When Japan was good it built in under 4 years, and had plans to go below 3. And no, that's not detrimental to safety.
> and use just isn't that important of a factor.
It is when land is expensive.
> With the electrification of cars and so on, the grid has to be modernized no matter what.
Typical dodge into the qualitative: the additional grad capacity required to ship power across the country from where it is produced to where it is needed is a multiple of that required to strengthen it for additional consumers. Never mind the whole "smart grid" madness.
> Most of the time nuclear also doesn't pay for decommissioning and nuclear waste etc. by itself.
That's also false. These costs are almost always included and have little impact on the total cost of power. For example, the Gösgen plant in Switzerland produces for 4,34 Rappen / kWh, including all costs and including a profit.
> At the same time a lot of renewable projects right now are also profitable without subsidize
That's also not true. When subsidies for off-shore wind were reduced, Germany, Denmark and the UK had zero bids for wind-parks, and immediately the discussion was "new subsidy models". Intermittent renewables in Germany currently get €20 billion in direct subsidies, never mind the advantage of having feed-in priority and being able to burden other producers with cost of intermittency.
> The Blackout in Spain had nothing to do with renewables
That's also not true. There was a trigger (in PV production) that led to a substation having problems. But that was just the trigger, not the cause. Grids have to be able to deal with faults like that from time to time. The grid in Spain wasn't, because there were too many intermittent renewables in the grid, and too few rotating masses that stabilize the grid.
> Grid scale batteries solve this problem.
Are these grid scale batteries sufficient to power an entire industrialized nation for a week or more in the room with us now? How much are they?
https://kernd.de/wp-content/uploads/2023/05/Artikel_atw_D_20...
Oh, interesting! If so, can you provide an example of anyone producing HEU starting from spent fuel?
Well, let's put it this way. If you want to create HEU you can either start from natural uranium, which is significantly easier to come by and isn't horribly radioactive. Or then you start from spent fuel, which is under IAEA safeguards (for other reasons), is very radioactive and thus very cumbersome, expensive and slow to deal with. Now which is more likely?
Not saying creating HEU from spent fuel is impossible, it's just a stupid way of going about it, and spent fuel already being covered by IAEA safeguards for other reasons so it's probably also going to be easier to detect such a hypothetical clandestine nuclear program.
> I think if you want to announce that reactors are useless for building bombs you need to provide a cite.
If you read my original response I explicitly mentioned that you need a reactor if you want to create a U233 or Pu based bomb. So I have no idea where you get such a notion from.
> Certainly nuclear non-proliferation work by real professionals does include the existence of a domestic nuclear industry.
True, but again not a point I have argued against.
For a well-established organization like Greenpeace, it becomes increasingly difficult to believe it's a matter of them collectively having an emotional reaction. They have the resources to look at the evidence, and have indeed almost surely done so; when it comes to explaining their refusal to accept that evidence, ”their jobs depend on rejecting it” is a much simpler explanation IMO than “they are experiencing a collectively-identical ideological quirk that their organizational bureaucracy somehow has yet to iron out”.
