FIELD: nuclear engineering.
SUBSTANCE: invention relates to nuclear engineering. Device for passive pressure control in the shell of a nuclear power plant consists of liquid spraying unit (40) in shell and pipeline (42) for liquid supply to feed liquid spraying unit (40). It also has intermediate tank (46) for liquid distribution placed between supply pipeline (42) and liquid spraying unit (40); intermediate tank (46) is connected prior to supply pipeline (42) and has side wall (52) for fluid outlet defining the borders of through holes (60) connected to liquid spraying unit (40). It has, at least one pipeline (44A-44D) for fluid removal to shell (19) protruding into intermediate tank (46) against side wall (52).
EFFECT: technical result is increased reliability of device for pressure control due to its structural simplification.
