ACTUAL PROBLEMS OF VIBROACOUSTIC DIAGNOSTICS OF THE FIRST CIRCUIT OF WATER-WATER ENERGETIC REACTORS
Cover not present ACTUAL PROBLEMS OF VIBROACOUSTIC DIAGNOSTICS OF THE FIRST CIRCUIT  OF WATER-WATER ENERGETIC REACTORS
Category: Number 25
Publication: 25
Summary

The analysis of features of development of resonant oscillatory processes in the first circuit of WWER-1000 reactors is made. The settlement acoustic scheme for determination of own frequencies of oscillatory pressure of a two-phase stream is considered. Typical ranges of pulsations of pressure, and also data on nature of destructions of elements of the first circuit are presented.

Keywords: vibroacoustic diagnostics, reactor installation, resonant oscillatory processes, own frequencies of fluctuations of the two-phase heat carrier, destruction of constructive elements.
