smic qualification of embankment slopes and earthworks important to safety will be performed and that the resulting designs, tests, and records will comply with established standards, thereby ensuring that slopes (natural or manmade) and earthworks will perform as required.30 6. 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 discussion of embankment dams and their foundations, natural and cut slopes, and all soil or rock slopes for which a lack of stability could adversely affect safety-related structures, systems, or components. Subsection 2.5.5.1 requires cross sections and profiles of the slopes and a description of the static and dynamic properties of soils and rock comprised by embankments. Groundwater and seepage conditions must also be described. Meeting this requirement provides assurance (a) that the nuclear power plant will be designed to withstand appropriately severe 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, and failure of embankment structures and earthworks.31 7. Compliance with Appendix A to 10 CFR Part 100 requires that the geologic and seismic conditions at the proposed site be considered during the siting and design of a nuclear power plant. Appendix A describes the investigations required to obtain the geologic and seismic data necessary to determine site suitability and to provide reasonable assurance 2.5.5-9 DRAFT Rev. 3 - April 1996 that a nuclear power plant can be constructed and operated at a proposed site without
