Instrumental observations at the Rivne NPP permanent seismic monitoring network
Keywords:seismic station, earthquake, depth, hypocenter, macroseismic observations
In accordance with the contract № 1881 dated 30.11.2018 between the State Enterprise «National Atomic Energy Generating Company "Energoatom"» and the National Center for Management and Testing of Space Means, specialists of the Main Center of Special Control carried out work on the analysis of the results of instrumental seismic observations on a permanent seismic network Rivne NPP monitoring. The article presents information about the organization and arrangement of the seismic monitoring network in the Rivne NPP area, as well as the results of the analysis of interfering conditions and the influence of microseims of different order on the ability of recording useful signals on the network elements. According to the records obtained using seismic sensors installed in instrument wells and on the day surface, the average values of the microseismic background at the checkpoints were calculated. In the course of instrumental observations, local, regional and tele-seismic events of different nature and energy levels were recorded. The vast majority of recorded earthquakes are located in Romania in the Vrancea seismic zone, Poland and southern Belarus.According to the results of seismic record processing, the intensity of shaking in the region of Rivne NPP was determined and conclusions were made regarding the necessity of changes of the initial data for the assessment of the seismic stability of the RNPP site.
