AbstractIt is shown that the vibration frequency of the main equipment of NPP with VVER-1000 falls in the frequency spectrum of the response corresponding to extending the maximum amplitude of the seismic action. It this work the results of the analysis of experimental data are presented. According to these results it follows that the logarithmic decrement of oscillations in the coolant may be less standardized to ensure seismic resistance values decrements for equipment and facilities. Expediency of full-scale experiments, under the impact of NPPs with VVER intended for decommissioning, artificially produced vibrations that simulate seismic and shock.
Keywordslogarithmic decrement, seismic resistance, frequency fluctuations, quality factor, resonance
