But the bottom line is that renewable costs are trending down, hard and fast, battery tech is just getting started, and development time for wind and solar is comparatively fast.
Future nuke costs at this point are speculative, development time is very slow, and even if new reactors were commissioned tomorrow, by the time they came online it's very, very likely solar and wind + storage would make them uneconomic.
IMO the attachment to nukes is completely irrational. There are obvious economic downsides, no obvious economic benefits - and that's just the money side.
