He is, in fact, arguing against keeping existing plants running too. (I suspected he believed this and he did indeed)

rules limiting how close they can be to residential buildings (apparently 10 times the height of the turbine)

These… don’t seem like crazy rules; I don’t know how this works in other legal systems but in the US every little podunk wind installation in a residential area is going to be tied up in years of lawsuits over this sort of thing.

building new nuclear instead of using the same resources to build solar or wind at this point means relying more on fossil fuels

I don’t think it is the same resources, that’s part of my point. I don’t think there’s a finite pool of money here; the limitations on solar / wind have as much to do with raw materials and suitable locations as anything else, if nuclear provides an additional path to getting carbon-free energy on line (and with the added benefit of not needing to worry about storage, which is going to bring its own rat’s nest of location + raw material problems once we get to it) then we ought to be encouraging it as well.
