There's a better solution: the molten salt reactor (MSR). Fueled by nuclear material dissolved in molten fluoride salts (essentially a liquid nuclear fuel--no such thing as a meltdown!), MSR's not only can consume all the nuclear waste, but then can use widely-available thorium-233 dissolved in fluoride salts as fuel. And there is a lot of thorium-233 our there--including possibly a lot on the Moon itself.

That’s the one I’ve heard of, the molten salt reactor.
