On June 10, 2013, the NRC issued a Notice of Violation to Entergy Operations, Inc. (Entergy) for a Severity Level III violation of NRC Regulations. Between December 14, 2010 and January 11, 2012, the licensee failed to maintain information required by the Commission's regulations as complete and accurate in all material respects. Specifically, a senior emergency planner formerly employed by Arkansas Nuclear One, deliberately falsified documents regarding the performance of Emergency Preparedness drills and communication surveillances. The senior emergency planner documented that the drills and surveillances were completed when they had not actually been performed. These actions caused Arkansas Nuclear One to be in violation of 10 CFR 50.9(a), which requires, in part, that information provided to the Commission by the licensee, or information required by the Commission's regulations to be maintained by a licensee, shall be complete and accurate in all material respects.
