used to transport and impound water supplied to the SSC important to safety. These requirements guide the Commission in its consideration of the suitability of proposed sites for nuclear power plants. In accordance with 10 CFR Part 100, Appendix A, cooling water canals and reservoirs should be designed to withstand the effects of the most severe hydrological phenomena noted in the previous paragraph. The function of the canal and reservoir is to provide adequate cooling water to safety-related components of the emergency core cooling system and to reactor auxiliary equipment during normal operations, anticipated operational occurrences, and accident conditions. More detailed guidance on the investigation of ultimate heat sinks is provided by Regulatory Guide 1.27. Meeting the requirements of 10 CFR Part 100 provides assurance that canals and reservoirs will be designed to withstand appropriately severe phenomena and remain capable of providing an adequate supply of cooling water to those structures, systems, and components important to safety during normal operations, anticipated operational occurrences, and accident conditions. 2.4.8-7 Revision 3 - March 2007 5. Sections 100.10(c) and 100.20(c) of 10 CFR Part 100 require that the site’s physical characteristics (including seismology, meteorology, geology, and hydrology) be taken into account when determining its acceptability for a nuclear power reactor. 10 CFR Part 100 is applicable to SRP Section 2.4.8 because it addresses the physical characteristics, including hydrology, considered by the Commission when determining the acceptability of a site for a power reactor. To satisfy the hydrologic requirements of 10 CFR Part 100, the applicant’s SAR should contain a description of the hydrological and seismic characteristics of the region and a description of the design bases of safety- related canals and reservoirs. The description should be sufficient to assess the acceptability of the site and the potential for
