Since we are taking about the planet about "the planet at stake" I am not so sure that nuclear in france can play such a big part. Climate change will make it much more difficult, this is from Wikipedia:
As of early September 2022, 32 of France's 56 nuclear reactors were shut down due to maintenance or technical problems. In 2022, Europe's driest summer in 500 years had serious consequences for power plant cooling systems, as the drought reduced the amount of river water available for cooling.

And rules around this have been adjusted to have less of an impact for the next "once in a 500 years" event.
Also, in the same way that France's nuclear power generation being out was covered by German and British renewables, during low points of renewable generation in those countries, French nuclear covered the gaps. That's the point of an interconnected network.
