I like to compare this to Site C in British Columbia https://www.bchydro.com/energy-in-bc/projects/site_c.html#:~.... If you are lucky enough to be blessed with remote untapped rivers that can be dammed in somewhat unpopulated mountain valleys (that's another story again), it seems to be far cheaper and safer. I would imagine that Nuclear power's main issue is first and foremost cost. If you could pull off completely safe nuclear power, it just winds up costing too dang much.
