wer Plants," describes laboratory investigations and testing practices acceptable for determining soil and rock properties and characteristics, together with their uncertainties needed for engineering analysis and design for foundations and earthwork for nuclear power plants in complying with 10 CFR Part 100 and 10 CFR 100.23. RG 1.198, “Procedures and Criteria for Assessing Seismic Soil Liquefaction at Nuclear Power Plant Sites,” describes acceptable methods for evaluating the potential for earthquake induced instability of soil resulting from liquefaction and strength degradation in complying with 10 CFR 100.23 and 10 CFR Part 50, Appendix S. RG 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. RG 1.208, "A Performance-Based Approach to Define the Site-Specific Earthquake Ground Motion," describes acceptable methods to: (1) conduct geological, seismological, and geophysical, and geotechnical investigations of the site and region around the site, (2) identify and characterize seismic sources, (3) perform probabilistic seismic hazard analysis (PSHA), (4) perform site response analysis, and (5) determine the site-specific ground motion response spectrum (GMRS) for the site. 2.5.4-7 Revision 5 – July 2014 A thorough evaluation of the geotechnical engineering aspects of the nuclear plant site as described in the following subsections must be presented along with the basic data supporting all conclusions. Sufficient information must be provided to allow the staff and its advisors to conduct independent analyses. The site investigations must be adequate in scope and in technique to provide the necessary data, including best estimate material properties together with their range of potential variability.
