France evened out demand by encouraging people to heat their water overnight using cheap electricity. We could do that, charge electric cars too and even produce Hydrogen for transport use (or peak demand Hydrogen powered generation).

What we need is some ingenious metering system to make this practical:-)

Hmmm, France managed with a system equivalent to economy-7, but using a signal imposed on the supply for switching rather than a local clock. Smart metering is just an invitation to suppliers to hugely increase prices at peak times and force people to either pay over the odds or change their entire way of living - eating later, washing and drying so late that they lose sleep, etc.

True for the UK, I believe the French PWRs have better capability to load follow.

I've no idea about the slew rates, but I suspect submarine PWRs can respond like gas turbines.

Another reason to keep UK nuclear plant for base load as far as reasonably possible is to minimise thermal (and hence fatigue) cycles.
