In the aftermath of what’s happened in Japan, we understand you’re asking about how U.S. nuclear plants are prepared for these sorts of events. Our technical experts in seismic events have taken time from their response efforts to answer almost two dozen of your most frequent questions.
We’ve posted that information on the NRC website here: http://www.nrc.gov/japan/faqs-related-to-japan.pdf . We’re working to keep that list as current as possible.
The bottom line remains the same – U.S. reactors are designed to safely ride out the strongest earthquakes at their sites, based on scientific review of at least 10,000 years of the geologic record at every site. Reactors on coastal sites are designed to withstand tsunami, hurricane storm surges and other flooding.
