manner and concurrent with that described in SRP Section 2.5.1. The services of consultants are used on selected sites to aid the staff in evaluating the geotechnical engineering aspects of particular sites. The results of site investigations (such as borings, geologic maps, logs of trenches and pits, permeability test records, results of seismic investigations, laboratory test results, profiles, and plot plans) are evaluated and cross-checked in detail to determine whether or not the assumptions used in the applicant’s evaluation are conservative. The design criteria are reviewed to ascertain that they reflect state-of-the-art and state-of-the-practice. For those facilities that have complex subsurface conditions, where marginal safety has been achieved, or where the applicant proposes to construct a seismic Category I earth or rockfill dam, an independent analysis of the design is performed by the staff or its advisors. To ensure that the safety implications of any new geologic information are reviewed, as described in SRP Sections 2.5.1 and 2.5.3, the staff proposes a geologic mapping license condition in the SER for each COL site where plant excavation and geologic mapping have not been completed prior to a license being granted. Review Procedures Specific to 10 CFR Part 52 Application Type 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 major structures are generally not known at the ESP stage and, therefore, some subsections within SRP Chapter Section 2.5.4 may not be complete. The subsections within SRP Section 2.5.4 2.5.4-20 Draft Revision 5 – August 2013 that are not complete in the ESP application will be reviewed in detail as part of the
