REVIEW RESPONSIBILITIES Primary - Hydrologic and Geotechnical Engineering Branch (HGEB)Civil Engineering and Geoscience Branch (ECGB)1 Secondary - None I. AREAS OF REVIEW Information, including analyses and substantiation, must be presented in the applicant's safety analysis report (SAR) and reviewed by the staff concerning the stability of all earth and rock slopes both natural and manmade (cuts, fills, embankments, dams, etc.) whose failure, under any of the conditions to which they could be exposed during the life of the plant, could adversely affect the safety of the plant. The following subjects must be evaluated using the applicant's data in the SAR and information available from other sources: 1. Slope characteristics (subsection 2.5.5.1); 2. Design criteria and design analyses (subsection 2.5.5.2); 3. Results of the investigations including borings, shafts, pits, trenches, and laboratory tests (subsection 2.5.5.3); and 4. Properties of borrow material, compaction and excavation specifications 2 (subsection 2.5.5.4). DRAFT Rev. 3 - April 1996 2.5.5-2 Review Interfaces3 1. The HGEBECGB will coordinate other branch evaluations that interface with the 4 geotechnical engineering aspects of the site as follows: performs the following reviews under the Standard Review Plan (SRP) sections indicated:5 a. Geosciences Branch (GB)The ECGB will determine the adequacy of the 6 geologic and seismic information cited in support of the applicant's conclusions concerning the suitability of the plant site and the stability of earth and rock slopes as part of its primary review responsibility for SRP Section 2.5.1. b. GBThe ECGB also reviews the seismological and geological investigations 7 carried out to establish the ground motion environment for seismic design of the plant, the procedures and analysis used by the applicant in establishing the safe shutdown earthquake (SSE) and OBE for the site, and the seismic design bases 8 for foundations as part of its primary review
