Large-Diameter Metal Seals for Nuclear Rocket Applications
Large-diameter metal seals are used in the reactor pressure vessel of nuclear rocket engines. Seals having nominal diameters over 40 in. are located at the main closure of the pressure vessel and at the pressure vessel-nozzle interface. Their environment includes cryogenic conditions imposed by the liquid-hydrogen propellant, and high-intensity nuclear radiation from the reactor. This paper describes development of several types of metal seals with functional characteristics that are successfully meeting the conditions introduced by the “large-diameter problem.”
