ability to perform their safety functions. SRP Section 2.5.4 describes guidance acceptable to the staff for determining soil and rock engineering properties as well as the dynamic stability, including liquefaction, of the subsurface materials. Meeting the requirements of Appendix S to 10 CFR Part 50 provides assurance that the nuclear power plant will be designed to withstand anticipated seismic phenomena and that during normal operations 2.5.4-15 Revision 4 - May 2010 or seismic events, the plant will pose no undue risk to the public as a result of instability, deformation, or failure of structural foundations and earthworks. Compliance with 10 CFR Part 100 requires that the Commission evaluate the suitability of proposed sites for nuclear power and test reactors. Paragraph 100.10(c) requires that physical characteristics (including seismology, meteorology, geology, and hydrology) be taken into account when determining each site's acceptability. To satisfy the geotechnical engineering requirements of 10 CFR Part 100, the applicant's SAR must contain a description of the proposed site's subsurface materials and foundation characteristics. This information will permit the reviewer to assess the acceptability of the site and to determine the potential influences of these characteristics on the design of plant structures, systems, and components. Meeting this requirement provides assurance (a) that the nuclear power plant will be designed to withstand anticipated geologic, geotechnical, and seismic phenomena and (b) that, during normal operations or seismic events, the plant will pose no undue risk to the public as a result of instability, deformation, or failure of structural foundations and earthworks. Compliance with 10 CFR 100.23 requires that the geologic and seismic conditions at the proposed site be considered during the siting and design of a nuclear power plant. It describes the investigations required to the obtain geologic and seismic data necessary to
