Replacing coal/ natural gas burning with solar is the priority by a big margin.

Unless there are safety issues, it makes sense to maintain nuclear plants at least until after any natural gas/ carbon emitting plants are shuttered.

At that point, it's cost/benefit & safety. At the current rate, it sounds like the cost of solar plus storage is likely to be less than nuclear by then regardless so this whole argument will be pointless.

The tiny nuke plants look pretty cool to me though!
