If something is Nuclear enough it can generate heat, its just the reactors make use of an actual reaction that nuclear waste can’t do anymore. Yever watch the Martian, he has a generator that’s fuel is lead covered beads of radioactive material, it doesn’t generate as much as reactors but it’s still a usable amount.
Yes, but energy density doesn’t matter for most applications and the waste it produces is highly problematic.

It’s a solved problem. https://www.youtube.com/watch?v=4aUODXeAM-k https://www.youtube.com/watch?v=lhHHbgIy9jU
