Content:
52.17, and 10 CFR Part 100, estimates of the probable maximum wind storm and the storm surge induced by the PMWS are needed. The PMWS should be considered for 2.4.5-5 Revision 3 - March 2007 locations along the Pacific and North Atlantic Coasts, and near large bodies of water such as the Great Lakes. The storm surge induced by the PMWS should be estimated as recommended by Regulatory Guide 1.59, supplemented by current best practices. 3. Seiche and Resonance. To meet the requirements of GDC 2, 10 CFR 52.17, and 10 CFR Part 100, estimates of seiche and resonance in water bodies induced by meteorological causes, tsunamis, and seismic causes are needed. An analysis of the interaction of seiche waves with the geometry of the water body should be carried out to determine if an amplification of wave heights due to oscillations at the natural periodicity of the water body is possible. An estimate of the minimum water surface elevation during the seiche activity should be provided to evaluate if safety-related water supply to the plant may be affected. 4. Wave Runup. To meet the requirements of GDC 2, 10 CFR 52.17, and 10 CFR Part 100, an estimate of wind-induced wave runup under PMH or PMWS winds is needed. The PMH or PMWS winds should be used to estimate wave runup as recommended by the U.S. Army Corps of Engineers (USACE) Coastal Engineering Manual. 5. Effects of Sediment Erosion and Deposition. To meet the requirements of GDC 2, 10 CFR 52.17, and 10 CFR Part 100, an assessment of loss of functionality of safety-related water supply to the plant caused by blockages due to sediment deposition or erosion during the storm surge or seiching is needed. If a hazard to SSC important to safety exists from sediment erosion and deposition, it should be documented and included in the design bases of these SSC. 6. Consideration of Other Site-Related Evaluation Criteria. The potential effects of site-related proximity, seismic, and non-seismic information as they relate to flooding
