| ENS 49468 | 23 October 2013 15:02:00 | A licensed employee had a confirmed positive test for alcohol during a random fitness-for-duty test. The employee's access to the plant has been placed on hold. The licensee notified the NRC Resident Inspector. |
| ENS 49359 | 19 September 2013 14:32:00 | Per 10 CFR 26.719 section (c)(3), Duke Energy is making this notification of an apparent false negative error that has occurred on a blind performance test sample submitted to the Health and Human Services (HHS)-certified laboratory used for drug testing. On September 18, 2013, Duke Energy was notified that a drug sample that was part of a blind performance test package provided by El Solhy and submitted to LabCorp tested negative. Duke Energy will investigate the issue and report to the NRC as required by part 26.719(c)(1). El Solhy and LabCorp are contracted by Duke Energy as required by NRC regulations to provide fitness for duty services. Duke Energy has notified the NRC Branch Chief for the Fitness for Duty program (Paul Harris), which advised that Duke needs to notify the NRC Headquarters Operations Center. |
| ENS 46669 | 11 March 2011 08:15:00 | During a performance of temporary operating procedure on a laser optical device, it was identified that one of two valves used to isolate the device failed to operate. The valves are operated as a pair and the valves are redundant to provide defense in depth. One valve shut as expected. The second valve did not shut. The valves are identified as an Item Relied on For Safety (IROFS). The system was not operating and one of the valves operated as designed. No unsafe condition existed. Operability of both valves is required to meet the performance requirements of 10CFR70.61. This event is being reported pursuant to the requirements of 10CFR70 Appendix A(b)(2) within 24 hours. The affected device will remain shutdown pending further investigation and implementation of associated corrective actions. (This event is of) low safety significance - the discovery did not result in an unsafe condition. |
| ENS 46486 | 17 December 2010 09:04:00 | During a performance of internal procedure to verify functionality of installed HF detectors in the Test Loop (TL) Gas Handling System (GHS) room, it was discovered at about 1044 (EST on) 12/16/10, that both IROFS TL-HF-01 and IROFS TL-HF-02 failed to pass internal test requirements. At least one of these HF detector IROFS is required to be available and operable to meet 10 CFR 70.61 performance requirements. The installed HF detector electrochemical sensors performance appears to have been degraded as a result of low room 'relative humidity' as a result of unusually cold outdoor conditions. The independent IROFS TL-HF-04 (an administrative control) remained intact, thus no unsafe condition existed. While one documented IROFS remained functional (TL-HF-04) to assure the consequence of chemical and radiological exposure is maintained low, TL-HF-04 could not alone meet 10 CFR 70.61 performance requirements. No loss of UF6 containment occurred in affected process equipment. The degradation of TL-HF-01 and TL-HF-02 was observed as part of the IROFS' periodic surveillance. This event is therefore being reported pursuant to the requirements of 10 CFR 70 Appendix A(b)(2) within 24 hours. The affected TL bench scale experiment equipment will remain shutdown pending further investigation and implementation of associated corrective actions. SAFETY SIGNIFICANCE OF EVENTS - Low safety significance - the discovery did not result in an unsafe condition. SAFETY EQUIPMENT STATUS - Required IROFS TL-HF-01 and TL-HF-02 functionality being re-established. STATUS OF CORRECTIVE ACTIONS - The affected TL process operation remains shutdown pending investigation and implementation of corrective actions. The licensee will be contacting NRC Region 2, state and local government agencies. |
