Abstract | A comparison of results of calculation of acoustic standing waves frequency with auto spectral power densities of the sensor signals of pressure fluctuations for complex combinations of acoustic elements of the 1st contour of nuclear power plants with WWER-440 is provided. The results of calculation of acoustic standing waves frequencies are found to be in satisfactory agreement with the measurement data. The new approach to calculate the acoustic characteristics of combination of number acoustical elements in the coolant system of the WWER-440 is worked out. The reactor with cold and hot pipelines as a complex Helmholtz resonator was studied for the first time. It is established that the frequencies of acoustic standing waves depend on the number of acoustic elements contained in the supply and discharge pipelines taken into account in the calculation |
