I mean, spent fuel is actually quite lethal when not packaged, but you get something like 300-400MWh out of a kilo of fuel. And that's significantly more than I'll use in my lifetime.

I'd gladly keep a kilo of dry-casked spent fuel in my house. It'd make an excellent coffee table or something, if a bit hard to move. I would absolutely not put a lifetime supply of benzene anywhere near my house.

Edit: it would make a shitty coffee table. 1 kilo of uranium oxide is just under 100ml
