inundation and drawdown caused by the tsunami wave. The staff should confirm that the parameters used in the simulation of inundation and drawdown are discussed with respect to their conservativeness. These effects should 9 e.g., v=√gd where d is the mean depth of the ocean and g is the gravitational constant. 10 A shallow water wave is typically defined based on the following condition: H/λ > ¼, where H is the mean water depth of the ocean basin in which the tsunami is generated and λ the wavelength of the tsunami. A deep water wave is typically defined when H/λ < 1/20. 2.4.6-8 Revision 4 - September 2018 be considered by the staff in its review of the application’s determination of the design bases of those affected SSCs important to safety. 5. Flood Event Duration Parameters. 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 information on the estimated warning time, duration of site inundation and drawdown near the proposed site including the powerblock. The staff should verify that the maximum extent and the longest duration of flood inundation and drawdown at the site is identified in the application for the purpose of preparing the flood protection and mitigation measures, as needed. 6. Hydrostatic and Hydrodynamic Forces. 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 describes the hydrostatic and hydrodynamic forces caused by the tsunami wave on those SSCs important to safety. The staff should verify that inundation and drawdown depths, current speed, acceleration, inertial component, and momentum flux near the proposed locations of those SSCs important to safety be included in connection with any description of the hydrostatic and hydrodynamic forces. These effects should be considered by the staff in its review of the application’s determination of the design bases of those affected SSCs
