The need for nuclear is simply not clear. Storage has advance so quickly, while nuclear tech has remained stagnant or even gotten more expensive.
Eve China, the best nuclear power builders out there, are shifting away from massive nuclear to storage and wind and solar.
Without a major technological innovation in the nuclear power space, I don't see how it can compete, except at the poles and in niches with very poor renewable resources.
Grid Storage is very expensive and right now only has a few hours of capacity. We would need weeks to really replace nuclear.
