NRC: Japan Lessons Learned

Japan Lessons Learned

On March 11, 2011, a 9.0-magnitude earthquake struck Japan and was followed by a 45-foot tsunami, resulting in extensive damage to the nuclear power reactors at the Fukushima Dai-ichi facility. The NRC has taken significant action to enhance the safety of reactors in the United States based on the lessons learned from this accident. This page is intended to serve as a navigation hub to follow the NRC's progress in implementing the many different lessons-learned activities.
