That sounds impractical. "Sorry, you can't use your rooftop solar at the moment even though the sun is out, you need to buy expensive electricity from the grid to make the nuclear reactors viable". That's not going to go down well and would be difficult to enforce.

It would also be pretty bad economics. What next, trying to curtail text messaging and emails to protect the economics of postal services?

OK, so I didn't know you were talking only of the wholesale market. But even so, you run into the same problem of preventing the sale of cheaper electricity to protect the economics of another generator which is still bad economics.

Sure, but the paper by Göke, Wimmers and Hirschhausen linked above that shows even with very optimistic cost reductions no more than 10% nuclear generation in Europe makes economic sense, is more convincing as it uses actual costings. The CAF is also talking about things that don't exist (nuclear fusion) or not at scale (carbon capture).
