On January 22, 2015, the NRC issued a Notice of Violation associated with a Yellow Significance Determination Process finding to Entergy Operations, Inc. (Entergy). The finding was associated with the failure to design, construct, and maintain the Arkansas Nuclear One, Unit 1 & 2 auxiliary building and emergency diesel fuel storage building flood barriers so that they could protect safety-related equipment from flooding. Entergy was cited for a violation of 10 CFR Part 50, Appendix B, Criterion III, "Design Control" and 10 CFR Part 50, Appendix B, Criterion V, "Instructions, Procedures, and Drawings." Both violations included multiple examples for each violation. |

On June 23, 2014, the NRC issued a Notice of Violation to Entergy Operations, Inc. (Entergy) for a violation of Title 10 of the Code of Federal Regulations, Part 50, Appendix B, Criterion V, "Instructions, Procedures and Drawings," associated with a Yellow Significance Determination Process finding at Arkansas Nuclear One, Unit 1, and a Yellow Significance Determination Process finding at Arkansas Nuclear One, Unit 2, involving the March 31, 2013, Unit 1 stator drop that affected safety-related equipment on both units. Specifically, Entergy approved a design for the temporary hoisting assembly that was not supported by detailed drawings, specifications, evaluations, and/or certifications as required by Entergy Quality Procedure EN-MA-119, "Material Handling Program." As a result, on March 31, 2013, while lifting and transferring the main generator stator, the temporary overhead crane collapsed causing the 525-ton Unit 1 stator to fall on and extensively damage portions of the plant, including safety-related equipment. |

(SL III) |
06/10/2013 |
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. |
