If the reactors we do have were running at capacity, I'll bet most of the energy supply problems would disappear. California could build two huge ones in the desert, one to supply the Northern state, and another to supply the Southern state. Crisis solved.
What about waste? Doesn't matter... If you don't take the uranium ore out of the ground, it leaches into ground water.
It would be a good idea to store the waste on the moon.
(I think this is why the television show Space 1999 was created - - to discourage the idea. They depicted the moon being blasted off into the nether regions of space by explosions. We know this is not possible. More info-tainment junk science for the unwashed.)
Yes the dangers of nuclear power are ridiculusly overstated. Including the fuel, we could just use breeder reactors like Japan has and throw the leftover fuel into a pit.
Use a standardized design, produced in clusters. Like California could have a bunch of nuclear plants all together. It makes things like repair, management etc.. a lot cheaper. Throw a couple breeders in with a cluster to recycle the fuel. And if its California throw a couple desalianation plants in too. And in the future plants to make hydrogen.
