of the appli- cant's model and its utilization. The model's theoretical basis, its inherent conservatism and applicability to the problem, will be evaluated (this can be done on a generic basis). The conservatism of the models' use, including the conservatism of all input parameters, will be evaluated. Coincident ambient tide and wave conditions will be evaluated to assure that they are of at least annual severity. Data from publications of NOAA, the Corps of Engineers, and other sources are used to substantiate these condi- tions chosen. Criteria and methods of the Corps of Engineers as generally summarized in Reference 15 are used as a standard to evaluate the applicant's estimate of coincident wind-generated wave action and runup. Criteria and methods of the Corps of Engineers and other standard techniques are used to evaluate the potential for oscillation of waves at natural periodicity. Criteria and methods of the Corps of Engineers. (Ref. 15) are used to evaluate the adequacy of protection from flooding, including the static and dynamic effects of broken, breaking, and nonbreaking coincident waves. IV. EVALUATION FINDINGS For-construction permit (CP) reviews, the findings will consist of a statement summarizing estimates of the maximum and minimum tsunami water levels, and static and dynamic effects of wave action. A statement of acceptability of the tsunami- induced design basis in meeting the requirements of GOC 2, 10 CFR Part 100, and 10 CFR Part 100, Appendix A will be made. If the tsunami conditions do not constitute a design basis, the findings will so indicate. For operating license 2.4.6-3 Rev. 2 - July 1981 (OL) reviews, the findings will consist of the evaluation of any new information on tsunami potential, improvements in predictive models, acceptability of specific design bases, and the acceptability of design provisions. A sample statement for a CP review follows: The staff concludes that the plant design is acceptable with respect to its ability
