Nuclear is more expensive than renewable alternatives, even with the cost of necessary storage taken into account. Moreover, renewables and storage have strong experience effects, while nuclear has shown negative experience effects, so this cost gap should only widen.
The fact that no merchant nuclear plant (privately financed, selling into a competitive market) has ever been built anywhere in the world should be a clue.
That doesn’t really matter much though. Uranium isn’t dangerous by itself, and has the highest energy density of any existing source.
Well.. it's not a huge deal but don't eat it. I have a bit of uranium ore on my bookshelf, but I avoid handling it and wash my hands after I do. Besides the alpha radiation, which isn't good for your insides, it's also toxic.
