st 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. 2.5.4-16 Revision 3 - March 2007 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 determine site suitability and to provide reasonable assurance that a nuclear power plant can be constructed and operated at a proposed site without undue risk to the health and safety of the public. 10 CFR 100.23 (d)(4) requires a determination of static and dynamic engineering properties of materials that underlie the site, thereby affecting (a) behavior during earthquakes and (b) transmission of earthquake-induced motions to the foundations of the plant. Guidance on geologic investigations that provide data on subsurface characteristics and materials properties is provided in Regulatory Guide 1.132. Guidance on laboratory testing of soil and rock properties is provided in Regulatory Guide 1.138. Guidance on procedures and
