Nuclear waste materials aren't hard to dispose of, they just have extremely high abuse potential. That's why they have to be safely stored for million years away from civilization, so that they cannot be dug up by current and future terrorists.

I think there was some ex-French colony government that demanded France disclose details of nuclear waste burial sites for "safety" reasons, which France rejected. Which means it happens. That kind of thing is why nuclear wastes are supposedly and actually so "dangerous" and small private owned generators get "complicated".
