Аннотация
In this paper, the influence of the reactor power on the LBLOCA hydrodynamics at the initial stage of the process (0-1 second) is considered. The calculations are carried out for the first loop in case of the beginning of loading, end of loading and constant power level. The strongest amplitude and frequency of pressure wave's fluctuations in NPP elements occurred during the first seconds of accident initiation. Thus, in the present work the analysis is focused on this period. These pressure fluctuations can lead to significant dynamic loads on the structural elements of the NPP. The parameters of a typical reactor plant V-320 (VVER-1000) were used in the calculation, particularly, the 3rd unit of the Kalinin NPP.
