One of the reasons we're producing so much radioactive waste is that we're too scared to reprocess spent fuel. There's a lot of fissionable material remaining in the "spent" fuel that can be recovered, enriched, and thrown back into a reactor. The more cycles you put it through, the less waste you'll end up with. But the same process can also be used to make bombs, so we force everyone to keep the spent fuel in a bunker or something.
