Afaik they have lots of momentum (for days even), and even their propenents argue for them being critical for providing a base supply^1^. Never have I heard anyone claiming they’d be good for matching fluctuating demand. Can you back that up?
Or are you getting your anti-reneweblaes lobbying talking points mixed up? That argument is usually used for natural gas plants.
^1^ which doesn’t make sense in a renewables dominated grid.

The closer the rods are to each other, the more collisions occur per unit time, and the more heat is generated.

That’s a super basic view on the science of nuclear power. As an engineer, I need a lot more than that, because it needs a lot more to put basic principles into working projects.
So, is there a nuclear powerplant, that exists outside of some powerpoint slides, that is actually used to match fluctuating generation from other energy sources and/or fluctuating demands?
All of the ones I know are/were used to provide a base supply by running more or less 24/7 at their designated output, not least because they need to do that to be even somehow economically feasible.

They do it in France. The term to google is “load following” nuclear power plants.

Kudos for a measured response to my sometimes snarky tone.

I only had the time to read the executive summary of this thing, but I learned a bit more about nuclear power plants.
It’s still not enough for me to evaluate how well that can integrate with a grid dominated by renewables (can the load following be fast enough, to match wind and solar fluctuations) but still good to know more.
