I like nuclear, but honestly I think it will simply be completely knocked out by renewables in a decade or so. It's more or less a given that renewables will be the way many - if not most - countries achive zero carbon emission. It's simply the cheapest and easiest way. It's a given that energy storage technology will keep developing at a rapid pace, because it's essential to decarbonizing the transport sector, and for balancing renewables which we absolutely need anyway. Nuclear will not be able to solve the problem fast and cheap enough alone. And nuclear isn't good at balancing renewables so it doesn't let us avoid solving the energy storage problem.
As the oil/gas sector starts scaling down, I think a lot of engineers from that sector will go into advanced geothermal. We're already seening some very promising developments, and in a decade I'm willing to bet it will take off.
Why build new expensive nuclear reactors when there's a completely free fusion reactor already in the sky, and a free fission reactor under our feet? All we have to do is to harvest the energy, and if you run the numbers there's way more energy than we could ever possibly need.
Btw. A small consern about nuclear is that they are thermal power plants. They add heat directly to our planet that wasn't there before. I was honestly very surprised to learn how significant that is for the impact on global warming. Much less than CO2, but still significant. If we get the impact of green house gases down a couple of orders of magnitude, then if we still have a lot of thermal power plants they could actually put a break on further progress.
Should absolutely continue nuclear R&D to enable the exploration of space though. Or just for the advancement of technology in general. And to hedge our bets. Still many reasons to be pro nuclear to a certain extent.
