REVIEW RESPONSIBILITIES Primary - Hydrologic and Geotechnical Engineering Branch (HGEB)Civil Engineering and Geosciences Branch (ECGB)1 Secondary - None I. AREAS OF REVIEW In this section of the safety analysis report (SAR) the hydrometeorological design basis is developed to determine the extent of flood protection required for safety-related plant systems. The areas of review include the characteristics of the assumed probable maximum hurricane or other probable maximum wind storms and the techniques, methodologies, and parameters used in the determination of the design surge and/or seiche. Antecedent water levels, storm tracks, methods of analysis, coincident wind-generated wave action and wave runup on safety-related structures, potential for wave oscillation at the natural periodicity, and the resultant design bases for surge and seiche flooding are also reviewed. For a standard design certification applications, the maximum flood level (from all sources) and design winds are specified in the site parameter envelope that must be met by the plant design.2 Review Interfaces3 The ECGB also reviews, under SRP Section 2.3.6 (proposed), the adequacy of the site parameter envelope specified in standard design certification applications. The ECGB also reviews, under SRP Section 2.4.2, the limiting flood level specified in the site parameter envelope for design certifications.4 DRAFT Rev. 3 - April 1996 2.4.5-2 II. ACCEPTANCE CRITERIA HGEB ECGB acceptance criteria for this SRP Standard Review Plan (SRP) section are based 5 6 on meeting the requirements of the following regulations: 1. General Design Criterion 2 (GDC 2) as it relates to structures, systems, and components important to safety being designed to withstand the effects of hurricanes and seiches. 2. 10 CFR Part 100 as it relates to evaluating the hydrologic characteristics of the site. Specific criteria necessary to meet the relevant hydrologic requirements of GDC 2 and 10 CFR Part 100 are as follows: If it
