ope of the review is dependent on whether the COL applicant references a DC, an early site permit (ESP) or other NRC approvals (e.g., manufacturing license, site suitability report or topical report). 10. For review of both DC and COL applications, SRP Section 14.3 should be followed for the review of ITAAC. The review of ITAAC cannot be completed until after the completion of this section. IV. EVALUATION FINDINGS The reviewer verifies that the applicant has provided sufficient information and that the review and calculations (if applicable) support conclusions of the following type to be included in the staff’s safety evaluation report. The reviewer also states the bases for those conclusions. 9.2.2-13 Revision 4 - March 2007 The reactor auxiliary CWS includes pumps, heat exchangers, valves and piping, expansion tanks, makeup piping, and the points of connection or interfaces with other systems. Portions of the reactor auxiliary CWS necessary for safe shutdown and accident prevention or mitigation are designed to seismic Category I and Quality Group C requirements. After review of the applicant’s proposed design criteria, design bases, and safety classification for the reactor auxiliary CWS as to the requirements for adequate cooling water for the safety-related ECCS components and reactor auxiliary equipment for all conditions of plant operation, the staff concludes that the design of the reactor auxiliary CWS is acceptable and meets the requirements of GDCs 2, 4, 5, 44, 45, and 46. These conclusions are based on the following findings: 1. The applicant meets GDC 2 requirements for system safety-related portions capable of withstanding the effects of earthquakes. Acceptance is based on RG 1.29, Position C.1 for the safety-related portions and Position C.2 for the nonsafety-related portions. 2. The applicant meets GDC 4 requirements for the effects of missiles inside and outside of containment, effects of pipe whip and jets, and environmental conditions caused
