It’s not really much of a problem. You leave the waste in a cooling pond at the plant for a couple of decades while you wait for all the really threatening stuff to decay, and then drive it where it needs to go in a truck. It’s a bunch of big metal rods in canisters. It can’t really “spill” and if it does you just pick it up and put it back in the truck. Uranium and plutonium are really not very threatening to human life.
