SEALING DEVICE TO CONTROL AND SUPPRESS LEAKAGE IN REACTOR Russian patent published in 2024 - IPC F16J15/00 G21C19/00 

FIELD: nuclear technology.

SUBSTANCE: invention relates to the field of maintenance and repair of nuclear power plant reactors, specifically to a sealing device for pressure testing to control reactor leaks. The device includes an upper fitting seal adjustment unit, which serves as a radial seal for the leakage control fitting. The said upper fitting seal adjustment unit is installed on the lower position control unit; and the lower position control unit is inserted into the nozzle of the upper block and enters into a sliding contact connection with the inner wall of the nozzle of the upper block. An adjustment ring is installed on the top of the lower position control unit, which is located on the lower sealing surface and is used to adjust the position of the lower position control unit inside the nozzle of the upper unit.

EFFECT: reduced workload on personnel, improved efficiency of pressure testing to control reactor leaks and ensure successful completion of the pressure test to control leaks, reduced likelihood of an event with an abnormal seal, and at the same time reduced overall value of the collective dose during pressure testing at control of reactor leaks.
