METHOD OF STEAM AND GAS GENERATORS CONTROL TIGHTNESS OF SHIP NUCLEAR ENGINE INSTALLATION WITH WATER HEAT TRANSFER MEDIUM UNDER PRESSURE Russian patent published in 2009 - IPC G21C17/22 

FIELD: physics; nuclear power.

SUBSTANCE: invention is intended for the control of tightness of steam and gas generators of ship nuclear engine installation on the stopped reactor, both at stationary pressure, and at carrying out of hydraulic trials. The method of tightness control of steam and gas generators of the ship nuclear engine installation with the water heat transfer medium under pressure includes sampling from each prestressly drained steam and gas generator on the stopped reactor and measuring of the content of tritium with the subsequent calculation of leaking quantity. Samplings of air moisture are performed from the pipe system of each steam and gas generator. Then tritium content in air of the pipe system of each steam and gas generator is determined. Before sampling, additional removal of water from pipelines of a contour of circulation of the drained steam and gas generators is performed. Sampling of moisture of air and determination of tritium content in air is performed with an interval of 24-48 hours.

EFFECT: increase of sensitivity of control method, possibility of earlier detection of steam and gas generator leakiness and possibility of determination quantity of leaking of the heat transfer medium of the first contour in specific steam and gas generator.
