es and characteristics needed for engineering analysis and design for foundations and earthwork for nuclear power plants in complying with 10CFR Part 100 and 10 CFR Part 100, Appendix A. (Ref. 11) The information in the SAR must be in compliance with the criteria presented in References 1 through 7. This section of the SAR is judged acceptable if the information presented is sufficient to demonstrate the dynamic and static 2.5.5-3 Rev. 2 - July 1981 stability of all slopes whose failure could adversely affect, directly or in- directly, safety-related structures of the nuclear plant or pose.a hazard to the public. The emergency cooling water source is of particular interest with regard to slope stability (Refs. 4 and 8). The secondary source of emergency cooling water should survive the operating basis earthquake (OBE) and design basis flood. Completeness is determined by the ability to make an independent evaluation on the basis of information provided by the applicant. Specific criteria necessary to- meet the relevant requirements of the Commission regulations identified above are as follows: Subsection 2.5.5.1. In meeting the requirements of References 3, 4, and 6 and the regulatory positions contained in References 8, 10, and 11, the discussion I of slope characteristics is acceptable if the subsection includes: 1. *Cross sections and profiles of the slope in sufficient quantity and detail to represent the slope and foundation conditions. 2. A summary and description of static and dynamic properties of the soil and rock comprising seismic Category I embankment dams and their founda- tions, natural and cut slopes, and all soil or rock slopes whose stability would directly or indirectly affect safety-related and Category I facili- ties. The text should include a complete discussion of procedures used to estimate, from the available field and laboratory data, conservative soil properties and profiles to be used in the analysis. 3. A summary and description of
