Use one of those bunker busters you have stored. The BIG one called a NUKE!! Drop a couple of those on that nuke plant. It will disappear in a flash of light!
You don’t need to make the nuke sites disappear. Just a slight green glow of radiation, rendering the entire facility uninhabitable for years will do.. Perhaps there is some other agent besides radiation that will have the same consequence. Hmmmmm, biochemical maybe?
