I wonder if it takes more energy to neutralize the waste than they get out of it when they put it in the nuke plant...
I don't know. I heard a physicist on Art Bell talk about nuclear capabilities of NK, and at the time Iraq.
The real worry about NK is detonating a bomb at altitude to create an artificial radiation belt - disrupting communications, surveillance, etc.
"They" are working on ways to clean that possible belt. (yet another use for HAARP????)
