James Dewar's book, The Nuclear Rocket.
Read the Intro by Robert Bussard. The same Robert Bussard of the polywell fusion concept, by the way.
Just wanted to make a note here about something else, because I didn't know about it and it struck me. One megawatt equals 50 lbs of thrust in a rocket. Just goes to show you how much power is in one of these things. You need nearly a gigawatt in order to get a medium sized rocket engine.
Mind-boggling.
