NUCLEAR POWER PLANT WITH HEAT CARRIER CLEANING SYSTEM Russian patent published in 2017 - IPC G21D1/02 G21C19/31 

FIELD: nuclear engineering.

SUBSTANCE: invention relates to nuclear engineering. Nuclear power plant (NPP) comprises an integral reactor with a housing and a cover, at least three heat carrier circulation circuits, intermediate (9) and process (14) heat exchangers, pipelines to feed and discharge the heat carrier from the intermediate and the process heat exchangers, shutoff valves and cleaning system (11) of alkali metal (4). Heat carrier cleaning system (11) consists of at least one membrane (4) and hydrogen and tritium receiver with the possibility of evacuation of its cavity (8) and discharge of received hydrogen and tritium from it. When selecting membrane (3) design taken into account are, first, interrelation of structural characteristics of the membrane with structural characteristics of the NPP, mass exchange characteristics of the membrane and the NPP, maximum allowable mass concentration of tritium in the product discharged from the third circuit (6); second, interrelation of mass exchange characteristics of the NPP and the maximum allowable mass concentration of tritium in the product discharged from the third circuit (6).

EFFECT: technical result is following radiation safety requirements for the product (tritium) discharged from the third circuit (6) of the NPP.
