DEVICE FOR COUNTING PARTICLES OF IONIZING RADIATION AND USE THEREOF FOR IMPLEMENTING A METHOD FOR MEASURING LEAKAGE FLOW BETWEEN THE PRIMARY AND SECONDARY CIRCUITS OF A STEAM GENERATOR

摘要

The invention relates to a device for counting particles of ionizing radiation. The device comprises detecting means 1 and a reference source 2 in advance of detecting means 1 and delivering a signal. REFERENCE RADIATION, THE SPECTRUM OF WHICH IS LOCATED OUTSIDE THE SPECTRUM OF IONIZING RADIATION TO BE DETECTED. MEANS 3 OF DISCRIMINATION IN AMPLITUDE AND IN ENERGY OF THE IONIZING RADIATION RECEIVED AND MEANS 4 PERMIT THE ADJUSTMENT OF THE RELATIVE POSITION OF IC AMPLITUDE AMPLITUDE LEVELS AND THE AMPLITUDE OF THE IMPULSES GENERATED BY THE RADIATION OF REFERENCE. / P P APPLICATION TO THE MONITORING OF LEAKAGE FLOW BETWEEN PRIMARY AND SECONDARY CIRCUITS OF A NUCLEAR POWER PLANT GENERATOR. / P
