On January 6, the NRC is holding a hearing on the threat flooding and other extreme events pose to nuclear plants. Flooding at Fukushima, Ft. Calhoun and at a number of Northeast plants during Hurricane Sandy has prompted the NRC to take a closer look at plant flood protections.

cart-horseDave’s presentation can be found here.

The other panelists will include Robert DeNight, operations director at the Salem plant in New Jersey; Stuart Lewis, program manager at the Electric Power Research Institute; Chandra Pathak, principal engineer for the U.S. Army Corps of Engineers; Geoff Bonnin, chief of the Hydrologic Science and Modeling Branch of the National Oceanic Atmospheric Administration; and Lance Vail, a senior research engineer at the Pacific Northwest National Laboratory. The full set of presentations is here.

This hearing will begin at 1:30 p.m. and will be webcast simultaneously.

    Relative to your comments on Slide #17, which approximately asks: should weight of (impacting) water be considered? it might be appropriate to give INPO credit for identifying this shortcoming in their November 2011 Special Report 11-005 on page 47, where they say:

    “The tsunami design basis for Fukushima Daiichi considered only the inundation and static water pressures, and not the impact force of the wave or the impact of debris associated with the wave.
