NOV (SL III) |
12/18/2013 | On December 18, 2013, the NRC issued a Severity Level III Notice of Violation to Aerotest Operations, Inc. involving the failure to implement Technical Specification 10.2. Specifically, for an indeterminate period of time beginning at a point after the last full fuel inspection in 2006 until October 15, 2010, when the facility ceased reactor operation, the licensee operated the reactor with significant defects in the fuel elements. During fuel inspections conducted following reactor shutdown, twenty two fuel elements were identified as having varying degrees of cracking in the aluminum cladding, representing a significant defect in the fuel elements and loss of the integrity of a fission product barrier. |
| EA-13-097 Aerotest Operations, Inc. |
ORDER | 07/19/2013 | On July 19, 2013, the NRC issued a letter to Aerotest Operations, Inc. denying an application for license renewal of the Aerotest Radiography and Research Reactor license because Aerotest is owned by a foreign corporation. The staff also denied an application for transfer of the license. As a result, on July 24, 2013, NRC issued an order prohibiting Aerotest from operating the reactor and placing the facility and its licensed material in a possession-only condition. The order also requires submission of an updated decommissioning plan and updated decommission funding. |

NOV (Yellow) |
06/23/2014 | 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. |
| EA-12-275 Arkansas Nuclear One |
NOV (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. |

|---|---|---|---|
| Armed Forces Radiobiological Research Institute, MD EA-20-056 |
Order | 11/19/2020 | On November 19, 2020, the NRC issued a Confirmatory Order (CO) to Armed Forces Radiobiological Research Institute (AFRRI) memorializing commitments reached during an alternative dispute resolution (ADR) mediation session held on September 18, 2020. The commitments were made as part of the settlement agreement between AFRRI and the NRC based on evidence gathered during an investigation in which the NRC had identified an apparent violation of 10 CFR 50.7, “Employee protection,” at the AFRRI Bethesda, MD facility. The apparent violation involved the discrimination (2-day suspension) against an AFRRI employee for engaging in protected activities. As a result of the CO, AFRRI committed to a number of corrective actions, including enhancements to its safety culture program, establishment of a Safety Conscious Work Environment program, as well as, independent third-party support. In consideration of the corrective actions and commitments outlined in the CO, the NRC will not cite the apparent violation and will not issue an associated civil penalty. |
