REVIEW RESPONSIBILITY Primary - Hydrologic and Geotechnical Engineering Branch (HGEB)Civil Engineering and Geosciences Branch (ECGB)1 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 identified 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 facilities," sandbags, flood doors, bulkheads, etc.) is reviewed. Any emergency procedures required to implement flood protection and warning times available for implementation thereof are reviewed, based on the flood conditions identified in other sections.2 If there is evidence of potential structural effects from flooding, the Structural Engineering 3 Branch (SEB) will be requested by HGEB toECGB will ascertain whether these effects are 4 properly considered in the structural design bases for the plant. DRAFT Rev. 3 - April 1996 2.4.10-2 Review Interfaces5 1. The ECGB will coordinate evaluations performed by other branches that interface with ECGB to complete the overall evaluation of the subject, as follows:6 a. similarly, Auxiliary Plant Systems Branch (ASB SPLB) will be requested by 7 HGEB ECGB to ascertain whether these effects of flooding are properly 8 considered in the systems design bases for the plant safety-related systems and components. Guidance for determining whether these potential effects are 9 considered properly is outlined in Standard Review Plan (SRP) Sections 3.4.1 and 3.4.2. the appropriate SEB and ASB SRP sections.10 b. The Human Factors Assessment Branch (HHFB) will be requested by ECGB to review any emergency procedures required to implement flood protection activities and warning times available for implementation
