to the extent this flood-causing mechanism is found to be consequential at the power reactor site 1. Historical Tsunami Data. To meet the requirements of GDC 2 (“Design Bases for protection Against Natural Phenomena”), GDC 44 (“Cooling Water”), 10 CFR 52.17 (“Contents of Applications; Technical Information”) and 10 CFR Part 100, the staff should confirm that the application includes a complete description of historically- reported information and/or instrumentally-recorded data on tsunamis or tsunami-like 2.4.6-7 Revision 4 - September 2018 waves near the proposed plant site. The staff should confirm that this description is sufficient to establish the history of tsunamis and tsunami-like wave occurrences in the vicinity of the site. 2. Tsunamigenic Wave Sources. To meet the requirements of GDC 2, GDC 44, 10 CFR 52.17, and 10 CFR Part 100, the staff should confirm that the application includes an assessment of the tsunami flood-causing mechanism for the proposed site. The tsunami assessment should include a review of tsunamigenic sources from historical, geological, and geomorphic data, both near field and far field, relevant to the proposed plant site. If no tsunami hazard for the proposed site is identified in the application, the staff should confirm that the application includes a justification based on the information reviewed. The staff should identify tsunamigenic sources in this review of the application, including earthquakes, submarine and sub-aerial landslides, and volcanoes. The staff should confirm that the characteristics of those geologic sources are described including parameter values associated with the tsunami wave generated at the site attributed to those sources. The staff should identify the location of the preferred tsunamigenic source used in the evaluation of flooding hazard and should assure that the basis for selection of the preferred source is provided. 3. Tsunami Propagation Model. To meet the requirements of GDC 2, GDC 44,
