The question is more like: “How dependent is France on uranium which is a finite resource?”
“The demand for uranium continues to increase, but the supply is not keeping up. Current uranium reserves are expected to be depleted by the end of the century, and new sources of uranium are hard to find. As a result, uranium prices have been steadily rising, with some estimates predicting a doubling of prices by 2030. This is causing a global uranium squeeze, where the demand for the resource is outstripping the supply.”
France: Let’s build more nuclear plants, also do not invest into renewable energy, also since we are used to wars for oil, why not having wars for uranium in the future too?
Ah yes, 4th generation nuclear reactors will save us, as will fusion reactors. We could make stuff work with existing technology, but that’s somehow not good enough. The whole future plans section of the wiki article https://en.wikipedia.org/wiki/Breeder_reactor reads like the technological challenges of these type of reactors are not as solved as you state it in your post.
Solar ans wind power will never ever be a good baseline energy production méthod. It’s complementary.
No, it is a perfekt baseline energy production method. France is buying our renewable energy, because it can’t produce enough with its broken nuclear power plants and the ones not producing full because of the drought. The numbers do not lie.

The optimum imho is:
-
The bulk of the generation from wind and solar, and nuclear for 15% - 20% base load. Also some Geothermal where cheap but it’s potential is small.
-
Grids improved to cover local and intermediate renewable generation, and extended to facilitate import/export.
-
Variable electricity pricing for demand shifting.
The result is vastly reduced need for storage, probably batteries used intelligently in a hierarchy of grid and home, compared to the naïve “just build wind and solar and batteries.”
Then add in:
- A 90% transition from personal cars to free green public transport (#FGPT), taxis, e-bikes, bicycles, and walking.
This all needs no new technology (although for nuclear there are several advances not yet used at scale: molten salt, small, modular, U238, thorium), it needs a fraction of the rare earths, and delivers a huge in reduction steel production courtesy of car recycling.

[P.S. Dams damage eco-systems so I’m not in favour of more hydro generation, and pumped hydro storage needs the spare water too.
Biomass not “net zero” and obviously not “zero” which we actually need. It’s just more carbon burning plus extra pollution from the agriculture and other products of combustion. It increases land use, and at present the industry is full of corruption with trees being burned sometimes alongside shredded car tyres… and subsidised!]
Well, you can potentially design them in a way, that you can control the energy output more easily. However, then they will be even less economical than they are now. If you run at lower output, you waste more fuel.
The real key factor is as the cost of uranium continues to go up and suffers potential shortages and supply issues the cost of installing solar and wind continues to drop - they got planning permission for a solar farm near me about a year ago and it’s already half way through having pannels installed, the speed they can do it is only going to keep increasing especially as more automated tools get developed. Then there’s the almost certainty of a breakthrough in chemistry reaching market which significant reduces cost and increases the range of locations suitable which would again drastically lower price per kWh while the price of running nukes continues to rise and they’re locked into decades of economic loss or they’ll choose to close them and all that investment and effort will be for nothing.
Well, “By the end of the century” is almost 80 years away, that is significantly longer than any normal nuclear power plant lasts.
Also it is very difficult to know which exact price someone pays for uranium because they normal dont buy on the spot market, but via long lasting contracts.
So from my point of view we don’t have sufficient information for a proper estimation of the situation.
