tes the instrumentation needed for flood protection, including the adequacy of detectors and alarms necessary to detect rising water levels within structures, and the consequences of flooding on other safety-related instrumentation and electrical equipment in accordance with SRP Section 7.5. The specific acceptance criteria and review procedures are contained in the referenced SRP sections. II. ACCEPTANCE CRITERIA Acceptance criteria are based on meeting the relevant requirements of the following Commission regulations: Acceptability of internal flood protection as described in the applicant's SAR is based on certain requirements of 10 CFR Part 50, Appendix A, General Design Criteria (GDC) and other regulations. 1. The requirements of 10 CFR Part 50, Appendix A, GDC 2 relate to the SSCs important to safety being designed to withstand the effects of natural phenomena such as earthquakes, tornados, hurricanes, floods, tsunami, and seiches without loss of capability to perform their safety functions. Meeting the requirements of GDC 2 includes evaluating 3.4.1-4 Revision 3 - March 2007 the effects of flooding from full circumferential failures of non-seismic, moderate-energy piping, which is not considered in SRP Section 3.6.2. 2. The requirements of 10 CFR Part 50, Appendix A, GDC 4 relate to the SSCs important to safety being designed to accommodate the effects of and to be compatible with the environmental conditions associated with normal operation, maintenance, testing and postulated accidents, including loss-of-coolant accidents. 3. 10 CFR 52.47(b)(1), which requires that a DC application contain the proposed inspections, tests, analyses, and acceptance criteria (ITAAC) that are necessary and sufficient to provide reasonable assurance that, if the inspections, tests, and analyses are performed and the acceptance criteria met, a plant that incorporates the design certification is built and will operate in accordance with the design certification, the provisions of
