06/04/2013 On June 4, 2013, the NRC issued a Notice of Violation (NOV) associated with a Yellow Significance Determination Process (SDP) finding, a White SDP finding, and a Severity Level III violation to Tennessee Valley Authority (TVA). The Yellow finding, a violation of Technical Specification (TS) 5.7.1, Procedures, was issued for the failure of Watts Bar personnel to maintain an adequate procedure to implement its flood mitigation strategy within 27 hours as described in Watts Bar's Updated Final Safety Analysis Report (UFSAR) from initial licensing to July 2012. The White finding, a violation of TS 5.7.1, Procedures, was issued for the failure of Watts Bar personnel to establish and maintain an adequate procedure to implement its flood mitigation strategy prior to September 30, 2009, such that earthen dams located upstream of the facility could potentially overtop, causing a subsequent breach and resulting in onsite flooding and the submergence of critical equipment. The Severity Level III violation involved the failure of Watts Bar personnel to implement 10 CFR 50.72(b)(3)(ii)(B) on December 30, 2009, when Watts Bar personnel failed to notify the NRC within eight hours upon confirmation that a postulated Probable Maximum Flood (PMF) level would exceed the current licensing basis and the design basis PMF flooding event would result in overtopping of critical earthen dam structures upstream of the Watts Bar facility.

06/18/2012 On June 18, 2012, the NRC issued a Confirmatory Order (Effective Immediately) to Tennessee Valley Authority (TVA) to formalize commitments made as a result of an ADR mediation session. The commitments were made by TVA as part of a settlement agreement between TVA and the NRC regarding an apparent violation of NRC requirements by TVA. The agreement resolves the apparent violation involving two subcontractor employees at Watts Bar Unit 2 who deliberately falsified work order packages for primary containment penetrations which caused TVA to be in apparent violation of 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures and Drawings, and 10 CFR 50.9, Completeness and Accuracy of Information, which was identified during an NRC Office of Investigations (OI) investigation. TVA agreed to a number of corrective actions as part of this Confirmatory Order, including but not limited to: (1) a prompt cessation of all containment electrical penetration work activities and the initiation of an internal review of the incident; (2) a root cause and extent of condition review; (3) procedural revisions and training related to the importance of 10 CFR 50.9 and procedural compliance; and (4) various site specific (Watts Bar Unit 2) and fleet wide communications which discuss expectations for assuring work activities are performed and documented in a complete and accurate manner. In consideration of these corrective actions and commitments, the NRC agreed to refrain from proposing a civil penalty and issuing a Notice of Violation or other enforcement action in this matter.

07/01/2014 On July 1, 2014, the NRC issued a Notice of Violation associated with a White Significance Determination Process finding to Wolf Creek Nuclear Operating Corporation (Wolf Creek) for a violation identified at its Wolf Creek Nuclear Plant involving the failure to comply with 10 CFR 50.47(b)(9) which required the licensee to maintain an emergency plan that uses adequate methods for assessing and monitoring the actual or potential offsite consequences of a radiological emergency condition.  Specifically, a calculational error in Wolf Creek's Electronic Dose Calculation Program (i.e., computer software) resulted in inaccurate offsite doses for the main vent stack pathway. The computer software failed to account for the filtered pathway for iodine and particulates thereby overestimating the radiological release when the effluent radiation monitor was in the accident mode.
EA-12-152
Wolf Creek
NOV 09/21/2012 On September 21, 2012, the NRC issued a Notice of Violation to Wolf Creek Nuclear Operating Corporation (Wolf Creek) for a violation of Technical Specification 5.4.1(a) and Regulatory Guide 1.33, Appendix A, Section 9.a, associated with a Yellow Significance Determination Process finding. The finding involved Wolf Creek’s failure to implement maintenance that affected safety-related equipment in accordance with written procedures. Specifically, although required by a work order, Wolf Creek failed to install insulating sleeves on two splices associated with a startup transformer protective relay circuit. The startup transformer subsequently experienced a trip and lockout during a plant trip because the two uninsulated wires touched and provided a false high phase differential signal to the protective relaying circuit. The protective lockout caused prolonged loss of offsite power to all Train B equipment and all non-safety related buses.
