REVIEW RESPONSIBILITY Primary - Hydrologic and Geotechnical Engineering Branch (HGEB) Secondary - None I. AREAS OF REVIEW The locations and elevations of safety-related facilities and of structures and components required for protection of safety-related facilities are compared with the estimated static and dynamic effects of design basis flood conditions identi- fied in safety analysis report (SAR) Section 2.4.2.2, to determine whether flood effects need be considered in plant design or emergency procedures. If flood protection is required, the type of flood protection ("hardened facili- ties", sandbags, flood doors; bulkheads, etc.) is reviewed. Any emergency proce- dures required to implement flood protection and warning times available for imple- mentation thereof are reviewed, based on the flood conditions identified in other sections. If there is evidence of potential structural effects, the Structural Engineering Branch (SEB) will be requested by HGEB to ascertain whether these effects are properly considered in the structural design bases for the plant; similarly, Auxiliary Systems Branch (ASB) will be requested by HGEB to ascertain whether these effects are properly considered in the systems design bases for the plant. Guidance for determining whether these potential effects are considered properly is outlined in the appropriate SEB and ASB SRP sections. II. ACCEPTANCE CRITERIA HGEB acceptance criteria for this SRP section relate to the following regulations: 1. 10 CFR Part 50, §50.55a requires structures, systems, and components to be designed and constructed to quality standards comnmensurate with the importance of the safety function to be .erformed. Rev. 2 - July 1981 USNRC STANDARD REVIEW PLAN Standard review plans are prepared for the guidance of the Office of Nuclear Reactor Regulation staff responsible for the review of applications to construct and operate nuclear power plants.
