the big problem with nuclear is just that there's kinda no real reason for it anymore, renewables are just cheaper and better now.

I guess maybe if you REALLY dedicate yourself to defending it, nuclear plants can make sense from a national security perspective? And it's something we could spin up if the sun fucking dissapears one day.
But a side from those two things i really can't see any reason to build more nuclear (bringing back reactors that were decommissioned might make sense, i don't know) when we could instead spend that effort on just plastering the landscape with wind turbines and solar panels and shove batteries in every apartment building..
