pplicant’s estimate or perform its own independent analysis using currently accepted runoff 2.4.3-7 Revision 4 - March 2007 generation and flood routing methods. The staff’s estimates are compared with the applicant’s estimates to determine their acceptability according to the acceptance criteria in Subsection II of this SRP section. 3. Consideration of Other Site-Related Evaluation Criteria. 10 CFR Part 100 describes site-related proximity, seismic, and non-seismic evaluation criteria for power reactor applications. Subpart A to 10 CFR Part 100 addresses the requirements for applications before January 10, 1997, and Subpart B is for applications on or after January 10, 1997. The staff’s review should include evaluation of pertinent information to determine if these criteria are appropriately used in postulation of the worst-case flooding scenario at the proposed plant site and in the adjacent streams and rivers. 4. Review Procedures Specific to 10 CFR Part 52 Application Types. A. 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. The scope and level of detail of review of data parallel that used for a CP review. In the absence of certain circumstances, such as a compliance or adequate protection issue, 10 CFR 52.39 precludes the staff from imposing new site characteristics, design parameters, or terms and conditions on the ESP at the COL stage. Accordingly, the reviewer should ensure that all physical attributes of the site that could affect the design basis of SSCs important to safety are reflected in the site characteristics, design parameters, or terms and conditions of the early site permit. B. Standard Design Certification Reviews. DC applications do not contain general
