Yeah if we want power at all there's a heavy carbon cost to it regardless where it comes from. Nuclear from what I understand is more compatible with our preexisting electricity networks because like coal it has big chunks of metal spinning to store energy giving the ability to react incredibly fast to changes in the network. Battery banks may be able to do this quick response, but the longevity of rare earth mineral based solutions although fancy has me concerned. Very little can degrade with a massive flywheel and the losses from nuclear to get it up and spinning would be far lower than say spinning it with motors as an energy store.

Long term I agree though, the complexities around nuclear don't paint it as our saviour. Maybe for now, and probably the next hundred years, leaning into nuclear is at least harm reduction
