REVIEW RESPONSIBILITIES Primary - Organization responsible for the review of power conversion systems Secondary - None I. AREAS OF REVIEW The circulating water system (CWS) provides a continuous supply of cooling water to the main condenser to remove the heat rejected by the turbine cycle and auxiliary systems. The specific areas of review are as follows: 1. Review of the performance of the CWS with respect to its functional requirements and the effects of adverse environmental occurrences, anticipated operational occurrences, or accident conditions such as loss of offsite power. 2. Review of the CWS and its interfaces with other systems to determine that a malfunction, failure of a component, or failure of a circulating water pipe, including the failure of an expansion joint, do not have unacceptable adverse effects on the functional performance capabilities of safety-related systems located in the immediate area. 3. Review of the design of the circulating water system with respect to the following: A. The capability to prevent or detect and control flooding of safety-related areas so that the intended safety function of a safety system or component will not be precluded due to circulating water system leakage. B. Provisions to annunciate abnormal and unsafe operating conditions. 10.4.5-2 Revision 3 - March 2007 4. Inspections, Tests, Analyses, and Acceptance Criteria (ITAAC). For design certification (DC) and combined license (COL) reviews, the staff reviews the applicant's proposed ITAAC associated with the structures, systems, and components (SSCs) related to this SRP section in accordance with SRP Section 14.3, "Inspections, Tests, Analyses, and Acceptance Criteria." The staff recognizes that the review of ITAAC cannot be completed until after the rest of this portion of the application has been reviewed against acceptance criteria contained in this SRP section. Furthermore, the staff reviews the ITAAC to ensure that all SSCs in this area of review are
