METHOD OF NOISE DIAGNOSTICS OF REACTORS WITH WATER UNDER PRESSURE Russian patent published in 2008 - IPC G21C17/00 

FIELD: heating, heat exchange.

SUBSTANCE: invention refers to nuclear power engineering, particularly to noise methods of diagnostics of reactors with water under pressure of the type of a water moderated water cooled power reactor (WWPR), and is designed to control pulsations of the process characteristics in the on-line mode, for example, to control and detect abnormal pulsations of heat carrier consumption, including those dangerous for its normal operation. The method of noise diagnostics of reactors with water under pressure includes registering of signals out and inside of zone sensors of various types; a combined processing of sensors signals fluctuation, at that registering and processing of sensors signals is performed simultaneously and continuously. A diagnostic signal is worked out by processing of the sensors signals results.

EFFECT: upgraded safety of reactor assembly operation.
