REVIEW RESPONSIBILITIES Primary - Plant Systems Branch (PSBSPLB) 1 Secondary - None I. AREAS OF REVIEW The service water system (SWS) provides essential cooling to safety-related equipment and may also provide cooling to nonsafety-related auxiliary components that are used for normal plant operation. The PSBSPLB reviews the system from the service water pump intake to the points 2 of cooling water discharge to assure conformance with the requirements of General Design Criteria 2, 4, 5, 44, 45, and 46. The ultimate heat sink (reviewed under SRP Section 9.2.5) provides the intake source of water to the SWS for long-term cooling of station features required for plant shutdown and also any special equipment required to prevent or mitigate the consequences of postulated accidents and as such is an interface system to the SWS. The SWS pump performance characteristics will be compared to the high and low water levels of the ultimate heat sink to assure that pumping capability can be provided for extended periods of operation following postulated events. Site-specific portions of the SWS may not be within the scope of the design submitted by applicants for design certification (DC) in accordance with 10 CFR Part 52. The SWS piping, valves, instrumentation, and controls within the DC applicant's scope are reviewed as part of the DC submittal. Site-specific portions of the design (may include the SWS pumps) are the responsibility of the COL applicant. The DC applicant's submittal should provide a conceptual design and interface requirements for that portion of the SWS outside the scope of the DC, as required by 10 CFR Part 52.3 1. The PSBSPLB reviews the characteristics of the SWS components (pumps, heat 4 exchangers, pipes, valves) with respect to their functional performance as affected by adverse operational (i.e., water hammer) and environmental occurrences including cold weather protection, by abnormal operational requirements, and by accident conditions DRAFT Rev. 5 -
