Russian Regulatory Approaches to Seismic Design and Seismic Analysis of NPPPiping

摘要

The paper presents an overview of Russian regulatory approaches to seismic design and seismic analysis of NPPrnPiping. The paper is focused on categorization and seismic analysis of nuclear power plant items (piping, equipment,rnsupports, valves, but not building structures). The paper outlines the current seismic recommendations, correspondingrnmethods with the examples of calculation models. The paper considers calculation results of the mechanisms ofrndynamic behavior and the problems of developing a rational and economical approaches to seismic design and seismicrnprotection.
