Content:
face with this section as follows: 1. The reviewer evaluates the potential causes of external flooding from natural phenomena and assesses the adequacy of techniques for flood protection in accordance with SRP Sections 2.4.1 through 2.4.14. 3.4.1-3 Revision 3 - March 2007 2. The reviewer evaluates postulated site flooding parameters in accordance with SRP Section 2.4 and provides for inclusion in SRP Section 2.0 review for a standard DC application. 3. The reviewer evaluates the acceptability criteria used for the design of structures that should withstand the effects of the design basis flood in accordance with SRP Section 3.4.2. 4. The reviewer evaluates the adequacy of the technical specifications related to low-water conditions in accordance with SRP Section 2.4.14 and reviews the adequacy of overall plant technical specifications in accordance with SRP Section 16.0. 5. The reviewer evaluates the adequacy of the applicant's listing of SSCs, the failure of which could prevent safe shutdown of the plant, in accordance with SRP Sections 3.2.1 and 3.2.2. 6. The reviewer evaluates the adequacy of the applicant's plant- and/or site-specific probabilistic risk assessment, including an internal and external flooding analysis, in accordance with SRP Section 19.0. 7. The reviewer evaluates the environmental effects of a pipe rupture on safety-related systems in accordance with SRP Section 3.6.1. 8. The reviewer evaluates the environmental qualifications of mechanical and electrical equipment in accordance with SRP Section 3.11. 9. The reviewer evaluates possible break locations in high and moderate energy systems during normal plant operation and the dynamic effects (e.g. pipe whip, jet impingement) of pipe breaks in accordance with SRP Section 3.6.2. 10. The reviewer evaluates 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
