DEVICE TO DIAGNOSE INTERCHANNEL INSTABILITY IN REACTOR WITH PRESSURISED WATER Russian patent published in 2011 - IPC G21C17/00

Abstract RU 2414759 C1

FIELD: power engineering.

SUBSTANCE: invention may be used to control pressurised water reactors. The following components are added into available device for diagnostics of interchannel instability in pressurised water reactor - unit of power calculation, unit of power signal spectrum calculation, unit of filtration bands shift calculation, unit of systematic noise signal discrimination level, filter of amplitude discrimination, channel to determine lever of alternating noise signal discrimination, system of reactor control. It makes it possible to identify harmonic row (with available frequency of main harmonics), characterising occurrence of interchannel instability, with high resolution ability.

EFFECT: invention provides for thermal and resource reliability of fuel assembly.
