ing water surface elevations across the reactor site, information on flood event duration, and associated effects consistent with projected flooding depths and durations. As mentioned above, the staff should state the bases for confirming the conclusions reached by the applicant. 1. Construction Permit, Operating License, and Combined License Reviews The following statements should be preceded by a summary of the site characteristics and parameters used for the plant: “As set forth above, the applicant has presented and substantiated information relative to the effects of the tsunami flood-causing mechanisms 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 effects of the tsunami flood-causing mechanism at the site and in the surrounding area are acceptable and meet the relevant requirements of 10 CFR Part 100 [10 CFR Part 100.10(c) or 10 CFR Part 100.20(c), as applicable] and [10 CFR Part 50, Appendix A, General Design Criterion 2] [or] 10 CFR 52.79]], with respect to determining the acceptability of the site. The staff finds that the applicant has considered the appropriate site phenomena for establishing the design bases for SSCs important to safety. The staff has generally accepted the methodologies used to determine the effects of the tsunami flood-causing mechanism reflected in these site characteristics, as documented in safety evaluation reports for previous licensing actions. Accordingly, the staff concludes that the use of these methodologies results in site characteristics containing margin sufficient for the limited accuracy, quantity, and period of time in which the data have been accumulated. The staff concludes that the identified site characteristics meet the relevant requirement(s) of 10 CFR Part 100.10(c) [or 10 CFR Part 100.20(c)] and [10 CFR Part 50, Appendix A, General Design Criterion 2] [or]
