1: How man reactors were built in the 1970s and are nearing end-of-life?
2: How many reactors has Europe built since 2005?
3: What's the overrun time of reactors in Europe, compared to China?
The only reasonable conclusion to draw is that the industry has existed. It was world class, but the institutional knowledge to bring it back to this quality does not exist and would need to be rebuilt for the new generation of reactors. And we are not even talking Generation 4 here.
Its also already operating the 57 french reactors as well as operating reactors in South Africa, China, Korea, Belgium, Finland.
Sure, the industry will need to grow, but claiming it basically has to start from 0 is ludicrous.

The only reasonable conclusion from your logic is that it would have felt like an even worse idea to build nuclear reactors in the 1970's. Yet, using today's hindsight, it was a great idea.
Airbus would have been a terrible idea: no one had built commercial airliners before, and only the US had the know-how. Today, we know otherwise.
etc.
That's just plain false, Airbus started as a cooperation between a lot of european aerospace companies, which had different a lot of know-how in different fields. For example Sud Aviation (later Aérospatiale, now Airbus) was the French part of the Concorde, they also had the Caravelle.
England also made what I consider to be the prettiest bomber ever made - the Handley-Page Victor
France built majority of their nuclear reactors after 70s oil crisis. So it made sense to have independent resources for them. So they won't need to rely on other nations, some of which were their former colonies that hated them. They had two strong reasons to keep a nuclear base electricity generations.
If the competition was renewables and storage rather than plants running on imported oil during the oil crisis it would have been.
75% of all new capacity in TWh (I.e. adjusting for capacity factor.) globally are renewables and storage. There’s no need to swim against the river.
34 nations have committed to tripling nuclear capacity, including the US, China, France, the UK and many others. And they are acting on this as well.
The tide is nuclear, no need to swim against it.
And no, countries also doing renewables in no way negates this.
Then turning around and not understanding that ”TWh” is already adjusted for capacity factor.
In my eyes it is hard to take you seriously when you don’t comprehend even basic physical properties of our grid and energy systems. Let alone economics, timelines, opportunity cost etc.
The tide is neither nuclear nor renewables.
The tide is "we've become advanced enough to know that there is no one-size fits all solution for energy generation and are taking a more nuanced approach to address the local and different energy needs of differing regions/grids".
I hate these online debates that frame things like "renewables vs nuclear" when the reality should be "zero-carbon emission sources vs carbon emission". The only part of nuclear is in that is if it should be on the table or not. But it is absolutely idiotic from that framework to take nuclear off the table because you're not saying "nuclear everywhere" you're saying "if nuclear makes more sense for this setting, then use nuclear".
Don't oversimplify things, it makes everything too complicated.
Consider opportunity costs. If all the public money that Europeans invested to nuclear (it started way before the 70s of course) was put into renewables/storage r&d, we would have had great renewables decades earlier, and by now would be swimming in it.
Europe has never stopped working on creating new and better nuclear reactor designs https://en.wikipedia.org/wiki/EPR_(nuclear_reactor) https://en.wikipedia.org/wiki/ITER
We haven't built a reactor in a long time. So those EPRs being built are all way behind schedule and thus costing substantially more.
You can design whatever you want. Building one is a whole different story. That's not an opinion that's just what happened at the first 2 EPRs and Hinckley point isn't going great either
Olkiluoto 3 started regular production in 2023, taking 18 years to build at a cost of €11 billion (3x over budget).
Flamanville 3 started regular production in 2024, taking 17 years to build at a cost of €13.2 billion (4x over budget) or €19.1 billion including financing in 2015 prices.
Hinkley Point C (two reactors) is currently estimated to have its first unit come online around 2030, taking 14 years with total costs now estimated at £31-35 billion / €36–41 billion (2x over budget) in 2015 prices.

It would really be great to understand (rather than me guessing) China's rationale to build these plants, and also their safety.
They generate about 5% of their electricity with nuclear. That's a lot, but is it enough to power the country if other alternatives stop being viable (war, shortages, ...?) Maybe it's OK for them that in such a situation, they just turn off enough residential power to last through the night with nuclear and storage. z
Do they see the nuclear research as dual use? My understanding is that nuclear subs and ships do use entirely different nuclear plants. Maybe research into small modular reactors is more dual use. There's also use for those reactors if they really want to build moon bases.
Maybe at their cost of the plans (I heard ≈3B for a 1+GW plant), this is actually competitive with solar+storage. It's definitely competitive with western nuclear power plants, if they want to export in other developing markets.
Small modular reactors need to be rolling out of a factory ready to go, so we can do large redundant arrays of them, put them on trains to transport them around, etc.
A nuclear power station making a couple MW should cost maybe a few million tops once we have the ability to make hundreds of them a year from a factory instead of creating these 20 year projects for gigantic facilities that are all bespoke

The UK is so disappointed by their HPC project (which is the most expensive nuclear reactor project in history, AFAIK), that they just completed the investment decision for the follow-up Sizewell-C, which will also be 2 UK-EPRs.
Oh, the guarantee price for HPC is the same as that for various off-shore wind-projects. So obviously economically uncompetitive. At 10 pence/kWh the two reactors at HPC will produce electricity worth £200 billion. Which does put the cost of £41 billion into perspective, despite that being the most ridiculously over-time and over budget nuclear project in history.
Actually, Flamanville 3 did not start "regular" production in 2024, they were just given go-ahead to go to full power a few days ago. It was first grid-connected in 2024 and then started a lengthy ramp-up phase. It slowly coming online was the time for the Cour des Comptes to give its verdict, which was pretty damning.
Flamanville 3 was probably the worst run nuclear project in French history. And even so, this "damning" verdict was that it FV3 would only be somewhat and in the worst case marginally profitable. But still profitable. Which is better than pretty much every intermittent renewables project out there, certainly in Europe.
EDF is often accused of receiving heavy state subsides, with the implication that this is to keep the nuclear power plants going or subsidize nuclear electricity. It is true that EDF gets state subsidies. For their intermittent renewable projects. Ba-da-dum-tss. The nuclear party of their business is tremendously profitable, despite being forced to subsidize industry through the ARENH program.
France finished Flamanville 3 in 2024. Finland finished Olkiluoto 3 in 2022. Are those not recent enough? both were EPR designs
Yes there are new ones but both of those are perfect examples of the lack of knowledge [1].
I'll quote: > Many of the organisations chosen to work on the different parts of the plant did not have any experience in nuclear, and little understanding of the safety requirements.
We'll get there. But yes, we're rebuilding a lot of lost knowledge and paying for the teething issues.

Three more were built in EU since 2000: one in Finland (Swedish/Finnish design) and two in Slovakia (Soviet/Russian design).

There's an awkward middle phase where they lie about how long and how much they will cost because the transparency will kill them before they start if real figures are used. But you only get a few chances to pull that trick.

I think this is a more American-centric comment than you realized... France had a bigger rollout in the 80's and a few from the 90's so there's another decade (*making this time key!*) before a slow decline. Also remember that France is a lot smaller than America so needs less power.
Not to mention, France exports a lot of electricity[0]. I want you to look pretty closely at that graph again. It says they exported 81.8TW this year. What's France's nuclear capacity? 380TW[1]. France exports about 15% of its total energy, more than all its hydro (it's next biggest source). You may be interested to see where that electricity goes....[2]
France can lose those reactors and be fine, Europe is a different story...

Besides, I'm not sure this fear even makes sense. What, China could "start from scratch" but "France" (or anywhere else) couldn't? What would make China so unique that such things couldn't be replicated elsewhere? This is a fallacy in logic making the assumption that once skills atrophy that they can never be restored or restore more slowly. If anything we tend to see skills restore far quicker from atrophy than from scratch! So why paint a picture of "give up"? Isn't that just making a self-fulfilling prophecy?

Is this satire?
They also rely on imports of uranium - e.g. from Niger, which recently had quite the fallout with France.
It does not look to me at even a casual glance that French nuclear tech could fully work on its own. Similar for the UK.
It is not just about the experts, the supply chain too. Although, of course how much that matters in comparison is the question, since pretty much everything nowadays depends on some faraway place.
Most of the French uranium is produced by Orano which is quite close to being a public company (95% owned by France). It comes from Canada, Kazakhstan and Niger.
Greenpeace is not a reliable source when it comes to anything having to do with the nuclear industry by the way.

> France's dangerous nuclear friendship with Russia
> France promises to support Ukraine. But its nuclear energy supply is closely linked to Russia. Former energy bosses earn a lot of money with Rosatom.
This is an article about Europe. Do you really believe France alone is operating 57 nuclear reactors, and producing 70% of its energy via fission, without the industry, the knowledge, and with no experts left? Is chatgpt running everything?
