METHOD FOR DETECTION OF GAS PERMEABILITY OF FUEL COLUMN OF HEAT ELEMENTS AND FOR DETECTION OF POSITION OF GAS-TIGHT LOCK Russian patent published in 1997 - IPC

Abstract RU 2072572 C1

FIELD: nuclear engineering, non-destructive investigation of exhausted heat elements. SUBSTANCE: method involves local cooling heat element part down to very low temperature in order to change gas characteristics in hollow chambers. Gas characteristics are checked by activity of Kr-85 in hollow chambers of heat element. EFFECT: simplified and pure method for detection of gas permeability in heat elements. 5 dwg
