Is A Nuclear Reactor A...... I am not sure if this is the right forum or not, I figure its about space stuff so it might be. My question is, could one safely use a nuclear reactor on a large-scale space station. Of course there is the issue of shielding, but since space stations have to be shielded against virtually all forms of radiation anyhow, adapting the shielding for a nuclear reactor would not be hard. My question is, would it work, and is it viable.
