Not the best quality image (coming from microfilm), but this shows a NASA-Lewis concept for a gas core nuclear rocket engine, circa 1960. Specific impulse was to be 2200 seconds, thrust 98,000 pounds, T/W 0.68, reactor diameter 16.6 feet, overall reactor length, 16.6 feet. The fuel would reach 20,000 degrees R, while the Hydrogen would get to 10,000 degrees R.

    interestingly, here the lettering FUEL and PROPELLANT last is hydrogene
    but how is Fuel (Uranium hexafluoride? ) handled:
    pump with trubopumps from fueltank into engine or pressure feed ?
    and who is fuel stored under control and cooled ?
