safety from being adversely affected. 1. Historical Tsunami Data. The application should provide a complete description of historical tsunami data near the proposed plant site. This description should be sufficient to establish the history of tsunamis and tsunami-like waves in the vicinity of the site. 2. Probable Maximum Tsunami. The application should provide an assessment of the PMT for the proposed site. The PMT assessment should include a review of tsunamigenic sources from historical, geological, and physical data, both near and far field, relevant to the proposed plant site. If no tsunami hazard exists for the proposed site, it should be so stated with justification based on the history and location of the proposed site. The tsunamigenic sources in this review should include earthquakes, submarine and sub-aerial landslides, and volcanoes. The characteristics of tsunamigenic sources should be described including parameter values associated with the PMT. The results from numerical simulations of PMT waves towards the proposed site should be provided. This simulation should use shallow water wave approximation where appropriate, and use nonlinear wave dynamics where the approximation is not valid. 3. Tsunami Propagation Models. The application should provide a description of the tsunami wave propagation models used in the applicant’s SAR. The parameters used in the PMT wave propagation simulations should be listed and discussed with respect to their conservativeness. A discussion of all data used to input the tsunami wave propagation models should also be included. 4. Wave Runup, Inundation, and Drawdown. The application should provide the extents and durations of inundation and drawdown near the proposed site. The methods and models used to simulate inundation and drawdown caused by the PMT should be described. The parameters used in the simulation of inundation and drawdown should be discussed with respect to their conservativeness. The maximum extents and
