Abstract

The article represents the results of measurement and numerical simulation of measurement of scramsystem efficiency of reactor plants performed during the reactor physical startup tests of Novovoronezh-2 units 1, 2 and Leningrad-2 unit 1. These power units are equipped with a reactor VVER-1200, therefore, one numerical simulation of measurement of scram-system efficiency on the basis of the reactor project was performed. The article represents comparisons of the calculated and the measured currents of the ionization chambers and the readings of reactimeter calculate for them during measurement of scramsystem efficiency.
