, including the adequacy of the type of flood protection utilized as part of its primary review responsibility for SRP Sections 2.4.1 through 2.4.14. The Structural Engineering Branch (SEB) determines the acceptability of the design analyses, procedures, and criteria used for structures that must withstand the effects of the design basis flood as part of its primary review responsibility for SRP Section 3.4.2. The Instrumentation and Control Systems Branch (ICSB) and the Power Systems Branch (PSB) will, upon request, verify the adequacy of instru- mentation needed for flood protection, including adequacy of detectors and alarms necessary to detect rising water levels within structures, and will evaluate the consequences of flooding on other safety-related instrumentation 'and electrical equipment in affected areas. The review of Technical Specifi- cations is coordinated and performed by the Licensing Guidance Branch as part of its primary review responsibility for SRP Section 16.0. For those areas of review identified above as being reviewed as part of the primary review responsibility of other branches, the'acceptance criteria necessary for the review and their methods of application are contained in the referenced SRP section of the corresponding primary branch. II. ACCEPTANCE CRITERIA 'Acceptability of the flood protection measures described in the SAR is based on meeting specific general design criteria and regulatory guides. The plant design for protection of SSC from the effects of flooding is acceptable if it meets the relevant requirements of General Design Criterion 2, "Design Bases for Protection Against Natural Phenomena," and 10 CFR Part 100, Appendix A, "Seismic and Geologic Siting Criteria for Nuclear Power Plants," Section IV.C as related to protecting SSC important to safety from the effects of floods, tsunamis and seiches. Acceptance is based on the design meeting the guide- lines of Regulatory Guide 1.59 with regard to the methods utilized for
