Current nuclear prices for 100% nuclear power is insane. You need both massive storage and operating at low power for long periods which drive something that’s not competitive into unreasonable territory. France got close with huge subsidies and exporting and importing a lot of power, but that’s hardly 100% nuclear that’s just pushing Europe’s Nuclear percentage up a little.
