LEAK CONTROL SYSTEM OF THE EQUIPMENT OF THE SECONDARY CIRCUIT IN THE BUILDINGS OF A LIGHT WATER POWER REACTOR Russian patent published in 2021 - IPC G21C17/00 

FIELD: water power.

SUBSTANCE: invention relates to a leak control system of the equipment of the secondary circuit in the buildings of a light water power reactor. The system is comprised of an air humidity measurement apparatus including air humidity sensors 3, a signal processing unit 4 wherein the outputs of the air humidity sensors 3 are connected with said unit by analogue communication lines 6, and an information apparatus 5, the input whereof is connected with the output of the signal processing unit 4 via a digital communication line 7. At least one air humidity sensor 3 is located in a controlled building 1 with the controlled equipment installed therein. The rest of the air humidity sensors 3 are located in at least one auxiliary building 2 communicating by the aerial environment with the controlled building 1. The signal processing unit 4 includes a signal summation module 9.

EFFECT: increase in the reliability of the equipment of the secondary circuit of the reactor unit due to the provided possibility of timely detection, localisation of leak, and determination of the flow rate of the leak.
