Ah I’d not consider these! That gives some hope too then :) I hope we get the battery advances we need asap, the urgency from the climate crisis is strong lately.

That's a limitation of the secondary power conversion side and is true for any power generation methodology that relies on steam generation. That said, there's alternatives to the traditional Rankine cycle that could be deployed without modifying the nuclear side of the plant.

I don't recall them being shut down (that would be a drastic step). They were forced to reduce output, though (making the energy more expensive).

there are a bunch of new reactor designs that don't use water.
