be used to aid the staff in geotechnical engineering evaluations regarding foundation engineering and slope stability analyses, particularly in the evaluation of safety-related and seismic Category I earthworks, earth and rock-fill dams, dikes, and reservoirs. The data needed to satisfy the requirements of this section are often incomplete in the early stages. However, sufficient field and laboratory data should be presented and conservatively interpreted to allow a realistic assessment of the safety of proposed slopes and supporting foundations. Detailed design investigations are usually still in progress and final design conclusions have often not been made. Most of the open items of Section 2.5 remaining at the time that the SER input is required are in the foundation engineering and slope stability areas because actual conditions may not be revealed until excavations are opened; site visits conducted after construction permit (CP) or combined license (COL) issuance are therefore necessary. All natural safety-related slopes are examined during at least one of the two site visits required of the staff. Because excavated slopes or embankments are not usually constructed until after a CP or COL has been granted, detailed as-built documentation of these slopes and embankments, as well as complete stability and safety analyses are necessary. 2.5.5-11 Revision 3 - March 2007 Review Procedures Specific to 10 CFR 52 Application Types 1. Early Site Permit Reviews Subpart A to 10 CFR Part 52 specifies the requirements and procedures applicable to the Commission’s review of an ESP application for approval of a proposed site. Information required in an ESP application includes a description of the site characteristics and design parameters of the proposed site. However, the specific locations of safety-related slopes are generally not known at the ESP stage and, therefore, SRP Chapter 2.5.5 may not be complete. The subsections within SRP Chapter 2.5.5 that are not
