The U.S. Nuclear Regulatory Commission (NRC) is announcing the availability of final Generic Letter 2015-01, “Treatment of Natural Phenomena Hazards in Fuel Cycle Facilities.” The generic letter requests information from licensees of fuel cycle facilities to demonstrate if compliance is being maintained with the regulatory requirements and applicable license conditions regarding the treatment of natural phenomena events in the facilities' safety assessments, and to determine if additional NRC regulatory action is necessary to ensure that licensees are in compliance with their current licensing basis and existing NRC's regulations. The NRC will use the information submitted by licensees in response to the generic letter to determine if additional regulatory action is warranted.


The final generic letter is available as of June 29, 2015.
