Content:
Drawdown. The staff reviews extent and duration of wave runup during the inundation phase of the PMT event. 5. Hydrostatic and Hydrodynamic Forces. The staff reviews static and dynamic force metrics, including the inundation and drawdown depths, current speed, acceleration, inertial component, and momentum flux that quantify the forces on any safety-related SSC that may be exposed to the tsunami waves. 6. Debris and Water-Borne Projectiles. The staff reviews the debris and water-borne projectiles that accompany tsunami currents and may impact safety-related SSC. 7. Effects of Sediment Erosion and Deposition. The staff reviews the effects of sediment erosion and deposition caused by tsunami waves that may result in blockage or loss of function of safety-related SSC. 8. Consideration of Other Site-Related Evaluation Criteria. The staff reviews the potential effects of seismic and non-seismic information on the postulated design bases and how they relate to tsunami in the vicinity of the site and the site region. 9. Additional Information for 10 CFR Part 52 Applications. The staff reviews additional information that will be presented depending on the type of application. For a COL application, the need for additional information depends on whether the application references an ESP, a DC, both, or neither. Information requirements are prescribed within the “Contents of Application” sections of the applicable subparts to 10 CFR Part 52. Review Interfaces Other SRP sections interface with this section as follows: 1. The flooding protection measures, if necessary for the SSC important to safety, are reviewed in SRP Section 2.4.10. 2. The review to ensure that adverse environmental conditions, including those from loss of water due to drawdown during the receding tsunami waves, seiching induced by tsunami, or blockage from sedimentation, will not preclude the safety function of the ultimate heat sink is performed under SRP Section 9.2.5, “Ultimate Heat Sink.” 3.
