COOLANT PRESSURIZER Russian patent published in 2001 - IPC

FIELD: nuclear, thermonuclear, and space engineering; high-temperature nuclear power plants using liquid-metal coolant. SUBSTANCE: pressurizer has pressurized housing with gas space, pressurizer-to-coolant-circuit junction unit, and gas-coolant interface. The latter is, essentially, capillary structure hydraulically connected with pressurizer-to-coolant-circuit junction unit and with gas space. Capillary structure may be made in the form of perforated gauze or foil rolls or in the form of perforated tubes. Gas filter may be installed between capillary structure and pressurizer-to-coolant-circuit junction unit. Pressurizer is suited to ground tests as part of coolant circuit under conditions close to those encountered when operating in space. EFFECT: enhanced reliability of pressurizer. 4 cl, 3 dwg
