Content:
Define the Site-Specific Earthquake Ground Motion,” describes acceptable methods to: (1) conduct geological, seismological, and geophysical investigations of the site and region around the site, (2) identify and characterize seismic sources, (3) perform PSHA, (4) perform site response analysis, and (4) determine the GMRS for the site (see SRP Section 2.5.2.6) using the performance-based approach. Regulatory Guide 1.206, “Combined License Applications for Nuclear Power Plants (LWR Edition),” provides guidance regarding the information to be submitted in a COL application for a nuclear power plant. The principal geologic and seismic considerations for site suitability are given in 10 CFR 100.23. Regulatory Guides 1.165 and 1.208 provide more detailed guidance on investigations and application of PSHA and development of the GMRS. The GMRS is based on consideration of the regional and local geology and seismology and on the characteristics of the subsurface materials at the site. However, no comprehensive definitive rules can be promulgated 2.5.2-5 Revision 4 - March 2007 regarding the investigations needed to determine the GMRS; the requirements vary from site to site. 1.
