I forgot to mention. NERVA, as ground tested, had around 800 sec specific
impulse.  The SSME only have 450 sec. And this was not a LOW thrust engine
like a SEPS. This was a real kick-in-the-buns interplanetary rocket engine.

Um, SSME? SEPS?  Not all of us can speak fluent acronym.  Could you
enlighten me as to what these mean?
