The plan that seems to make the most sense is to encapsulate the radioactive waste in glass beads and sink them three miles down in an old salt mine - or a special purpose built deep cave.
This process is being developed by a friends brother at UC Davis in the ceramic engineering dept. I think he has published a number of papers on the technique.
The biggest problem with nuclear waste is that the enviro/socialist watermelons won't be satisfied with anything you do....so the plan should be to ignore them!!
I have begun to think that some type of operant conditioning is required. Fit the little fart-blossoms with dog-training collars. Every time they run their mouths, shock the tar out of 'em. They'll finally get the message to shut up unless they have something intelligent to say.
