Ladies and Gentlemen:

On March 12, 2012, the Nuclear Regulatory Commission (NRC) issued Reference 1 to all power reactor licensees and holders of construction permits in active or deferred status. Enclosure 1 of Reference 1 requested each addressee perform a Flood Hazard Reevaluation (FHR). To adequately provide that report in accordance with the guidance provided in Reference 2, Southern Nuclear Operating Company (SNC) requested that the NRC obtain specific information from the U.S. Army Corps of Engineers (USACE) and for that information to be provided to SNC. On May 6, 2014, SNC provided additional information to the NRC that resulted from the April 29, 2014 meeting between SNC, the NRC and the USACE.
