Recycling a nuke doesn't create much waste. The main components of a nuke are the fissionable material = reused as is (plutonium has a rather long shelf-life), the chemical explosive = reused ( a lot of the explosive used in gulf-war-1 was WW11 surplus stuff, baritol and compB explosives can be remelted and recast continually), and possibly a neutron trigger which does decay - but into a less radioactive isotope. The only waste is irradiated casings, but since Pu isn't really that radioactive it's a lot less of a problem than a used cancer therapy machine.
