You use Hydrogen gas as the coolant on a nuclear reactor, then vent it out the
backside ('hot' as in thermally hot, not radioactive)
The radiation from it is not all that intense...space is a vast area, and
radiation dies off at the square of the distance.
Interestlingly enough, the USAF also flew a nuclear powered bomber. (B-47?
Big thing, with 4 Nucular heated jet engines. It could just fly on the nuke
only.

Thats a different idea. That one can get you from earth to anywhere...and I
think it was Orion. _really_ bad fallout problems with it, so not very much
use except in a emergency. (read "footfall" J. Pournelle/L. Niven for a
description of it in action.
