have been designed to withstand the most severe flood resulting from dam failure likely to occur.14 2. Section 100.10(c) of 10 CFR Part 100 requires that the site's physical characteristics (including seismology, meteorology, geology, and hydrology) be taken into account when determining its acceptability for a nuclear power reactor. 10 CFR Part 100 is applicable to SRP Section 2.4.4 because it addresses the physical characteristics, including hydrology, considered by the Commission when determining the acceptability of a site for a power reactor. To satisfy the hydrologic requirements of 10 CFR Part 100, the applicant's SAR must contain a description of the hydrologic characteristics of the region and an analysis of potential dam failures. The description must be sufficient to assess the acceptability of the site and the potential for those characteristics to influence the design of structures, systems, and components important to safety. Meeting this requirement provides a level of assurance that structures, systems, and components important to safety have been designed to withstand the effects of high water levels resulting from failure of upstream dams, as well as those of low water levels resulting from failure of a downstream dam.15 2.4.4-5 DRAFT Rev. 3 - April 1996 3. Appendix A to 10 CFR Part 100 requires that geologic and seismic factors include a determination of site suitability and acceptability of the nuclear power plant design. Paragraph IV(c) describes the investigation required to obtain geologic and seismic data for evaluating seismically induced floods, including failure of an upstream dam during an earthquake. Appendix A is applicable to SRP Section 2.4.4 because it requires investigation of seismically induced floods or low water levels that guide the Commission in its consideration of the suitability of proposed sites for nuclear power plants. More detailed guidance on the investigation of seismically induced floods is provided Regulatory Guide
