IMPROVEMENTS IN OR RELATING TO NUCLEAR REACTORS

Patent ·
OSTI ID:4081066
A high-pressure gas-cooled, D/sub 2/O-moderated reactor is designed in which a thick stainless steel pressure vessel for D/sub 2/O containment is lined with a graphite neutron reflector covered with an aluminum membrane to prevent D/ sub 2/O-graphite contact. In this way, the moderator can be pressurized by contact with coolant gas to eliminate the pressure differential on the coolant tubes and to enable operation at 150 deg C without neutron loss due to absorption in the pressure vessel walls. The pressure differential across the pressure vessel is eliminated by connection to the coolant gas circuit. (D.L.C.)
