Content:
(with input from GB) will review the potential tsunami sources analyzed by 13 the applicant to assure ensure that all locations capable of generating a tsunami of significant 14 magnitude at the site have been considered. The GBECGB staff will evaluate the geoseismic 15 parameters of the tsunami generators, including fault location and orientation, and amplitude and areal extent of vertical displacement, to assure ensure that conservative values have been chosen. An independent staff analysis, using one of the models listed in the references, may be performed. Staff estimates of tsunami levels are compared with the applicant's. The applicant must justify, to the staff's satisfaction, tsunami levels more than 5% less conservative than the staff's. As an alternative, the staff may perform an independent evaluation of the applicant'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 model's use, including the conservatism of all input parameters, will be evaluated. Coincident ambient tide and wave conditions will be evaluated to assure ensure 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 conditions chosen. Criteria and methods of the Corps of Engineers as generally summarized in Reference 15 1616 are used as a standard to evaluate the applicant's estimate of coincident wind-generated wave action and runup. DRAFT Rev. 3 - April 1996 2.4.6-6 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 16) are used to evaluate the adequacy of protection from flooding, including the static and dynamic effects of broken, breaking, and nonbreaking coincident waves.
