IEW PROCEDURES The reviewer will select material from the procedures described below, as may be appropriate for a particular case. 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. 2.4.5-7 Revision 3 - March 2007 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. Probable Maximum Hurricane. This section of the SAR may also state with justification that storm surge estimates are not necessary to identify the flood design basis (e.g., the site is not near a large body of water). All reasonable combinations of probable maximum hurricane, moving squall line, or other cyclonic wind storm parameters are investigated, and the most critical combination is selected for use in estimating a water level. The staff use data and methods recommended by National Oceanic and Atmospheric Administration (NOAA) National Hurricane Center to evaluate an applicant’s analysis of the PMH near the site, as described by NOAA National Weather Service Report 23 for the U.S. Gulf and East coasts. A PMH is specified in terms of several meteorological
