Flooding Reevaluations (ARCHIVED)

Note: This is an archived web page. For the most up-to-date information, see the new Post-Fukushima Safety Enhancements page.

Flooding Reevaluations Operating reactor sites are using present-day information to reevaluate the flooding effects—or hazards—that could impact their site.  These newly reevaluated hazards, if worse than what the plant had originally calculated, will be analyzed to determine if plant structures, systems, and/or components need to be updated to protect against the new hazard.  The NRC will review each step in the analysis process and take action to require plant changes as necessary.
