IMPROVING THE RELIABILITY OF NPPS ON THE BASIS OF THE DATA VIBROACOUSTIC CERTIFICATION
The article considers the problem of providing seismic resistance of nuclear power plants. It is shown that at resonance the vibration of NPP equipment and pressure pulsations of the fluid is abnormal growth of vibrations and dynamic stresses in the materials of construction, which increases the likelihood of equipment failure. The analysis concluded the need for vibro-acoustic certification of units in order to predict and prevent conditions arising vibro-acoustic resonances in NPP equipment at various stages of operation
