es 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. Compliance with Appendix S to 10 CFR Part 50 requires that nuclear power plant SSCs important to safety be designed to be able to withstand the effects of natural phenomena, such as earthquakes, without loss of capability to perform their safety functions. SRP Section 2.5.5 describes guidance acceptable to the staff for determining the static and dynamic stability, including liquefaction, of any dams, dikes, and embankment slopes important to safety. 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 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 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
