Content:
water system consists of complex water sources, including canals and reservoirs necessary to transport and impound plant cooling water. The design function of cooling water canals and reservoirs is to provide adequate cooling water to service or component cooling water systems so that plant components required to maintain adequate core cooling remain functional during normal operations, anticipated operational occurrences, and accident conditions. Meeting the requirements of GDC 44 provides assurance that cooling water canals and reservoirs will be designed to supply adequate cooling water during normal operations, anticipated operational occurrences, and accident conditions, thereby protecting against loss of core cooling.12 4. 10 CFR Part 100 requires that hydrologic characteristics be considered in the evaluation of a nuclear power plant site. Appendix A to Part 100 addresses the need to consider an adequate cooling water supply for emergency and shutdown decay heat removal in the design of a nuclear power plant. The evaluation shall include consideration of river blockage or diversion, tsunami runup or drawdown, and failure of dams and intake structures, as appropriate. In accordance with 10 CFR Part 100, Appendix A, cooling water canals and reservoirs must 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. DRAFT Rev. 3 - April 1996 2.4.8-6 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
