Summary

An analysis of the features of resonant vibratory processes in the primary circuit of VVER-1000. We consider the acoustic design scheme for determining the natural vibration frequencies of pressure two-phase flow. Shows typical spectra of pressure fluctuations, as well as data on the mode of the destruction of the first circuit elements.

Keywords: reactor VVER-1000, the first circuit, two-phase flow, pressure pulsation, the natural frequency.
