Abstract
The results of vibro-acoustic investigation of laboratory model of the fourth circuit of nuclear power plant are presented. It is shown that the spectrogram of hydrodynamic noises is the solid spectrum, on the background of which there are the pronounced discrete components. The centrifugal pump and the throttling orifice are the main reasons of vibrations and noise. The recommendations of how to minimize the hydrodynamic noise in such systems are given. The results of investigation can be used for stationary and floating nuclear power plants and also for other types of power plants.
