摘要

The dynamic behavior of the pressure of coolant in the equipment of nuclear power stations (NPSs) equipped with VVER-1000 reactors is simulated, and its natural frequencies are calculated. The results of calculations are shown to be in satisfactory agreement with the data of measurements carried out at an NPS. The conclusion that there are hidden dynamic processes in NPS equipment that degrade its reliability and shorten its service life is substantiated.
