Thanks for that. There's a list of the various US military small reactor projects here.There's a good summary of the history of (and current plans for) small, portable nuclear reactors here:

Interestingly Camp Century is back in the news, and not for good reasons. The refuse left behind when the base was abandoned (including diesel, PCBs and mildly radioactive water) may cause pollution problems now that the Greenland ice-sheet is melting.
Aww, I think the idea of a giant nuclear powered Arctic explorer vehicle is cool. Sort-of like the Antarctic Snow Cruiser but with more axles and a reactor.(In case anyone's wondering, the portable Soviet nuclear reactor on tracks is a TES-3 Portable nuclear power plant. It is often mistakenly assumed to be a nuclear-powered land vehicle. This is not possible, as the nuclear power plant has no connection to the vehicle's propulsion system.)
Perfect for an RPG set around Camp Century or an Antarctic Space Nazi space. Shades of The Ice Warriors, Who Goes There? and Assault on the Mountains of Madness.
