| Abstract | The accident at the Japanese nuclear power plant Fukushima Daiichi, which occurred as a result of the earthquake in 2011, has led to an understanding of the need for more stringent requirements imposed on the providing of seismic stability and to the justification of the possibility of extending the service life of nuclear power plants. Under these conditions, it becomes more urgent realizing the benefits and encouraging the further development of processes and research of vibration -acoustic resonances in nuclear power plants that have been worked out in the NRU "MPEI" in recent decades for safety, seismic stability and competitiveness of domestic nuclear power plants A number of published results that worked out for the first time in the world in the NRU "MPEI" and up to the moment hitherto unparalleled are included in the global scientific database World Wide Science. org as a key global research results. The paper presents the developed and verified methods and algorithms for calculating the frequency of acoustic standing waves and identifying the sources of their occurrence. The main current direction of research and design works, in which the results could be applied are indicated. |
