PROCESSING AND ANALYSIS OF THE RESULTS FROM INSTRUMENTAL OBSERVATIONS AT THE PERMANENT SEISMIC MONITORING NETWORK, RIVNE NPP

Abstract

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 microarrays of various orderтon the ability to record useful signals on the network elements. The average values of the microseismic background at the checkpoints were calculated based on the records obtained using seismic sensors installed in instrument wells and on the day surface. In the course of instrumental observations, local, regional, and teleseismic events of different nature and energy levels were recorded. The vast majority of recorded earthquakes are located in Romania in the Vrancea seismic zone, in Poland, and in 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.
