REVIEW PROCEDURES The reviewer will select material from the procedures described below, as may be appropriate for a particular case. 2.4.10-6 Revision 3 - March 2007 The procedures outlined below are used to review CP applications, ESP applications, and COL applications that do not reference an ESP to determine whether data and analyses for the proposed site meet the acceptance criteria given in Subsection II of this SRP section. For reviews of OL applications, these procedures are used to verify that the data and analyses remain valid and that the facility’s design specifications are consistent with these data. As applicable, reviews of OLs and COLs include a determination on whether the content of technical specifications related to hydrology-related site characteristics are acceptable and whether the technical specifications reflect consideration of any identified unique conditions. These review procedures are based on the identified SRP acceptance criteria. For deviations from these acceptance criteria, the staff should review the applicant’s evaluation of how the proposed alternatives provide an acceptable method of complying with the relevant NRC requirements identified in Subsection II. 1. Safety-related Facilities Exposed to Flooding. The staff compares locations and elevations of the SSC important to safety to identify those SSC that may be exposed to flooding, consistent with the site characteristics related to highest flood water surface elevation with coincident wind-wave action that were determined during the staff’s review of the applicant’s SAR, Sections 2.4.2 through 2.4.7, and 2.4.9. A detailed analysis of hydrostatic and hydrodynamic forces, erosion potential, and other causes that may endanger the safety function of the SSC exposed to floods should be included. The staff considers all flooding mechanisms and their individual characteristics and interactions with the SSC
