o the proposed plant site to estimate the most severe flood water surface elevation that may affect SSC important to safety. 3. Dynamic Effects on Structures: To meet the requirements of GDC 2, 10 CFR 52.17, and 10 CFR Part 100, an estimate of dynamic effects of flood waves, such as velocities and momentum fluxes, on SSC important to safety is needed. If a potential hazard to SSC important to safety exists from dynamic effects of flood waves, it should be documented and included in the design bases of affected facilities. 4. Loss of Water Supply Due to Failure of a Downstream Dam: To meet the requirements of GDC 2, 10 CFR 52.17, 10 CFR Part 100, and 10 CFR 100.23(d), an assessment regarding loss of safety-related water supply to the plant caused by failure of a downstream dam is needed. If the possibility of loss of safety-related water supply exists, it should be documented and the design of safety-related water supply to the plant should be reassessed. 5. Effects of Sediment Deposition and Erosion: To meet the requirements of GDC 2, 10 CFR 52.17, 10 CFR Part 100, and 10 CFR 100.23(d), an assessment is needed 2.4.4-5 Revision 3 - March 2007 regarding loss of functionality of safety-related water supply to the plant caused by blockages due to sediment deposition or erosion during the dam failure-induced flood event. If a hazard exists that may lead to loss of functionality of safety-related water supply, it should be documented and the design of the safety-related water supply to the plant should be reassesed. 6. Failure of Onsite Water Control or Storage Structures: To meet the requirements of GDC 2, 10 CFR 52.17, and 10 CFR Part 100, an assessment is needed regarding the failure of any onsite water control or storage structures that may cause flooding of SSC important to safety. If a hazard exists that may lead to flooding of SSC important to safety, it should be documented and included in the design bases of affected facilities. 7. Consideration of Other
