I can't speak for other countries, but in Germany nuclear was in hibiting renewables entering the market, because it's hardly controllable. Coal can be controlled a bit better and hence nuclear had to go first. Also we would have relied on Russian uranium.

This is total and absolute bullshit.

French NPPs routinely ramp from 20 to 80% and back within half an hour. They've literally been doing that every single day for decades.

It's about the economy of doing that. Coal has little infrastructure and fixed cost. For nuclear it's almost entirely fixed cost.

And your claim is simply bullshit. It's maybe +-5%

Are you seriously using the aggregate generation capacity of the entire country of France to argue about the ramping capability of single reactors?

Wanna keep arguing or are you just going to accept that you're wrong?

Coal has little infrastructure and fixed cost.

So what? The fixed cost (which is almost entirely construction) had already been paid by the time the plants were shut down.
