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.
only antimatter could provide more energy density, it’s insanely powerful.
produces amounts of waste orders of magnitude lower than any other means of energy production
reliable when done well
it shouldn’t be replaced with renewables, but work with them
Yes, but energy density doesn’t matter for most applications and the waste it produces is highly problematic.
