Has some information on the subject in question.
apparently it is not all that bad even in atm, but 250 K lbs thrust is not all
that much when launching large objects, especially from a 15-20K lb + fuel
motor.
(It's the burn times that are neat, 6-8 hrs at 250K lbs thrust is quite a
substantial delta-V for even a very heavy object)
I know that there was some pictures shown in one of the films of the 'nuclear
waste' type films (sorry, don't remember the name, but I do know it showed the
inside of the NERVA building, and the motor on the stand. (one of the motors
is still on the stand, I assume without fuel in it :)
