Sure, highly theorical:

When combining the different capabilities, power variations of up to 10,000 MW could be absorbed by German NPPs in 2010. In France, with an average of 2 reactors out of 3 available for load variations, the overall power adjustment capacity of the nuclear fleet equates to 21,000 MW (i.e. equivalent to the output of 21 reactors) in less than 30 minutes.

Of course they don’t use it unless force to, as the article states it’s cheaper to ramp down fossil fuels than nuclear. And this its a benefit, not a problem. But its also cheaper to ramp down nuclear than renewables, and this is also a benefit.

Nuclear andrenewablees are a better match than fossil and renewables, and right now we are doing fossil and renewables. We’ve been decades pussing for no nuclear in the hopes of getting only renewables and we’ve gotten fossil and renewables.
