So you want to create a completely new industry. From the ground. With all existing experts having retired. Demanding high quality, no-fault tolerance production. Dependent on resources not found in Europe.

Look, I love nuclear technology. But time has moved on. The costs to rebuild this industry is astronomical and means we lose out on key-future technology like batteries.

Edit: But then there are bombs. And especially French love their nukes due national security. This is the only reason to keep pushing for nuclear, since Russia, the US and China are not gonna change direction on this either. But the very least we could do is be honest about it.

Edit 2: Changed from "World has moved on" to "time has moved on", since evidently China has invested for a good 2 decades to build their own fully functional nuclear-industry. Proving my point that it takes dedicated investment, network effects and scale to rebuild this industry. After all, they too want to mass produce nukes.

Er...what?

There is a massive nuclear renaissance in-progress.

According to the following tracker:

https://globalenergymonitor.github.io/maps/trackers/nuclear/

There are currently 419 reactors in operation, 76 in construction, 140 in pre-construction and 290 planned/announced. I have a slightly older version of that chart, where those numbers were 69, 92 and 178, respectively.

Note that both the numbers are pretty large compared to the installed base (more than doubling the installed base), that they are increasing for the earlier stages (indicating more is in the pipeline than is currently being built), and that all the pipeline stages are increasing over time.

Which is of course consistent with the fact that 34 countries have now signed the international pledge to triple nuclear output that was first agreed at COP28. These countries include: France, the United States, China, Japan, Poland, Sweden, etc. India has plans and is on track to triple by 2032, but hasn't signed the pledge.

I am also not sure why you think that "all existing experts" have retired and there is no nuclear industry. The World Nuclear Exhibition in Paris November 4-6 of this year had over 1000 exhibitors, and more than half of those were from Europe.

Even phase-out-Germany still has substantial nuclear engineering capacity, there's even a nuclear fuel factory in Lingen. And of course the actual nuclear component of a nuclear power plant is only around 20%. About the same effort/cost goes into the steam turbines, of which Siemens is a major worldwide supplier.

And of course civil nuclear programs have next to nothing to do with military nuclear programs. There are many more users of civil nuclear power than there are military nuclear powers, and the military nuclear powers invariably got the bomb first, and added a civil program later, with some like Israel only having a military nuclear program, not a civilian one.

In fact, there's a fun anecdote from the beginnings of the French nuclear program, since you mention France: when the Messmer plan got started, the military wanted to deploy an indigenous type of reactor for the civilian program that was more suitable for military uses, but in the end the government decided to standardize on a US Westinghouse pressurized water reactors that was not useful for military purposes.

At about 1 GWatt per reactor, thats about 500 GWatt total new nuclear built over what must be decades, if it is built at all. A fair chunk of the existing 419 reactors will be retired in that time.

Meanwhile, Gemini tells me the planet added well over 100 GW renewable generation in 2024. That 100 GW is dispatchable. It was over 500 GW peak. Almost no renewables were retired in 2024. The rate new renewables are being added is growing at least quadratically.

Maybe Europe sunshine and wind resources mean they have no choice, it's nuclear or nothing. But renewables are being added at the pace they are for a reason. In the places that do have the renewable resources, they are far cheaper. If Europe is forced to go down the nuclear path, they are going to be paying far more than other places on the planet for their energy.
