@Baldimo,
As I said, DOE has ALL the responsibility to protect our stockpiles, fuel rods, reactors, research facilities and weapons grade nuke plants (there are a bunch, all the way from UF6 to stockpile and , "cake piles" trigger plants, and DOD nuke weapons storage units (I believe that the DOD has responsibility once a nuke is deployed to an air base or a ship or sub-but Im not sure).
NEST teams are DOE as are the HS forces that del with "dirty bombs".
Does the reason for weapons become clearer?
