Ranking of Deviations from Normal Operation of the Equipment in a Nuclear Power Plant According to the Degree to Which the Equipment Influences the Installed-Power Utilization Factor

The results of an analysis of deviations from normal operation of equipment in nuclear power plants with various types of power-generating units, with these deviations being ranked according to how strongly they affect the electricity underproduction, including in correlation to the year of operation of the power-generating unit, are presented.Because the number of power-generating units studied is large and the period of operation of the units is long (76 reactor-years of operation of VVÉR-440 units, 146 reactor-years for VVÉR-1000, and 110 reactor-years for RBMK-1000 were studied), the results obtained are representative and can be used as initial data for developing an economically substantiated program of technical measures to increase the installed-power utilization factor.
