METHOD FOR INSPECTING WATER-COOLED GRAPHITEMODERATED REACTOR CHANNELS FOR CONDITION Russian patent published in 2001 - IPC

Abstract RU 2166807 C2

FIELD: nuclear power plants. SUBSTANCE: in order to determine relative damage to channels, clearances between channels and graphite stacking, location of channels under inspection where deviations from normal conditions are suspected, total intensity of decay products of gas fraction activation and value characterizing concentration of corrosion products in gas are checked simultaneously for all channels, measured values are used to determine their ratio and the ratio of mean values, and condition of channels is estimated by data obtained. EFFECT: improved accuracy, speed, and reliability of inspection results. 13 dwg
