version important to the design and siting of this plant. The staff has reviewed the available information provided and for the reasons given above, concludes that the identification and consideration of the potential for channel migration and/or river diversion is acceptable and meets the requirements of 10 CFR Part 50, Appendix A, General Design Criteria 2 and 44 and 10 CFR Part 100 (10 CFR 100.10(c) or 10 CFR 100.20(c), as applicable), with respect to determining the acceptability of the site. The staff finds that the applicant has considered the appropriate site phenomena in establishing the design bases for SSCs important to safety. The staff has generally accepted the methodologies used to determine the potential for channel migration or diversion is reflected in these design bases, as documented in safety evaluation reports for previous licensing actions. Accordingly, the staff concludes that the use of these methodologies results in design bases containing margin sufficient for the limited accuracy, quantity, and period of time in which the data have been accumulated. The 2.4.9-16 Draft Revision 4 – September 2018 staff concludes that the identified design bases meet the requirement(s) of 10 CFR Part 50, Appendix A, General Design Criteria 2 and 44 and 10 CFR 100.10(c) or 10 CFR 100.20(c), with respect to establishing the design basis for SSCs important to safety.” 2. Early Site Permit Reviews The following statements should be preceded by a summary of the site characteristics and design parameters to be included in any ESP that might be issued for the ESP site: “As set forth above, the applicant has presented and substantiated sufficient information pertaining to the identification and evaluation of the potential for channel migration or diversion at the proposed site. Section 2.4.9, “Channel Migration or Diversion,” of NUREG-0800, Standard Review Plan, provides that the site safety analysis report should address the requirements of 10 CFR Parts
