safety function of the source, or that an alternate source of safety-related water supply exists that is also not similarly affected. 5. Effects of Sediment Deposition and Erosion: Sediment deposition during the flood resulting from dam failure should be estimated to ensure that safety-related functioning 2.4.4-8 Revision 3 - March 2007 of all SSC exposed to this flood is not impaired. Erosion caused by high velocity of flood waters should be estimated, and its effect on the foundations of SSC important to safety should be examined. Any potential erosion should not affect the safety-related functioning of SSC. 6. Failure of Onsite Water Control or Storage Structures: If any onsite water control or storage structures exist above the site grade, failures of these from any cause should be determined and the potential for flooding of SSC important to safety and doors and openings identified. It should be shown that this mode of flooding does not compromise the safety-related functioning of SSC or other exposed plant systems. 7. Consideration of Other Site-Related Evaluation Criteria: 10 CFR Part 100 describes site-related proximity, seismic, and non-seismic evaluation criteria for power reactor applications. Subpart A to 10 CFR Part 100 addresses the requirements for applications before January 10, 1997, and Subpart B is for applications on or after January 10, 1997. The staff’s review should include evaluation of pertinent information to determine if these criteria are appropriately used in postulation of worst-case flooding scenario from dam failures. 8. Review Procedures Specific to 10 CFR Part 52 Application Type A. Early Site Permit Reviews: Subpart A to 10 CFR Part 52 specifies the requirements and procedures applicable to the Commission’s review of an ESP application for approval of a proposed site. Information required in an ESP application includes a description of the site characteristics and design parameters of the proposed site. The scope and level of
