Content:
f the NRC’s regulations identified above are as follows for the review described in this SRP section. The SRP is not a substitute for the NRC’s regulations, and compliance with it is not required. However, an applicant is required to identify differences between the design features, analytical techniques, and procedural measures proposed for its facility and the SRP acceptance criteria and evaluate how the proposed alternatives to the SRP acceptance criteria provide acceptable methods of compliance with the NRC regulations. Appropriate sections of the following Regulatory Guides are used by the staff for the identified acceptance criteria. Regulatory Guide 1.27 describes the applicable ultimate heat sink capabilities. Regulatory Guide 1.29 identifies seismic design bases for safety-related structures, systems, and components. Regulatory Guide 1.59, as supplemented by best current practices, provides guidance for developing the hydrometeorological design bases. Regulatory Guide 1.102 describes acceptable flood protection to prevent the safety-related facilities from being adversely affected. 1. Probable Maximum Hurricane. To meet the requirements of GDC 2, 10 CFR 52.17, and 10 CFR Part 100, estimates of the probable maximum hurricane and the probable maximum storm surge, i.e., the storm surge induced by the PMH, are needed. The PMH, as defined by NOAA NWS Report 23, should be estimated for coastal locations that may be exposed to these events. If a PMH is not considered a design basis for the proposed site, documentation of the reasons should be provided. The storm surge induced by the PMH should be estimated as recommended by Regulatory Guide 1.59, supplemented by current best practices. 2. Probable Maximum Wind Storm. To meet the requirements of GDC 2, 10 CFR 52.17, and 10 CFR Part 100, estimates of the probable maximum wind storm and the storm surge induced by the PMWS are needed. The PMWS should be considered for 2.4.5-5 Revision 3 - March 2007 locations
