Once you have nuclear to supply half of average demand, here’s the key question: should you run it all the time, or should you turn it on and off, or ramp it up and down, as wind and solar generation may be available to meet the same demand?

Just use nuclear to charge the batteries for peak demand.

“Just use nuclear to charge the batteries for peak demand.”

Or use pumped storage (of water, of course) for the same, as is widely done in the US...if you don’t want a little battery cell issue taking out the entire system.

Problems with this article:
Nukes are very hard to turn On and OFF.
They are the ultimate Base Power.

And Batteries are extremally expensive.
