| Title | Technical Specification Violation Due to Operator Leaving Control Room |
| Event Description | Technical Specification 6.7.2(1)(c) Special Report Violation of Technical Specification 6.1.3(1)(a)
The following special report is being made in accordance with the requirements of Technical Specification (TS) 6.7.2(1)(c) which states in part: There shall be a report not later than the following day by telephone or similar conveyance to the NRC Headquarters Operation Center of any reportable occurrence as defined in TS 1.3. TS 1.3 defines an observed inadequacy in the implementation of administrative or procedural controls, such that the inadequacy caused the existence of a condition which results in a violation of technical specifications as a reportable occurrence. Specifically, on Friday October 4, 2013, while performing a training session, an operator left the control room while the console key remained in the console key switch and the switch was in the ON position. This is in direct violation of the staffing requirements defined in TS 6.1.3(1)(a) which states a licensed reactor operator must be in the control room when the reactor is not secured. The reactor was not secured by the fact that the console key switch was not in the OFF position and the key remained in the console key switch. However, all control elements were fully inserted, a normal reactor SCRAM condition was present, the reactor was shut down, no work was in progress involving core fuel, core structure, control elements or drives and no experiments were being moved. This condition remained for a period of 67 seconds until the reactor operator returned to the control room. The reactor operator subsequently secured the reactor and notified the Reactor Supervisor. A review of security records confirms the control room remained locked and unoccupied during the entire duration. A follow-up written report to the NRC describing the circumstance of the event including an analysis of the cause of the occurrence, corrective actions and measures to prevent or reduce the probability of the recurrence shall be made no later than 14 days from today, October 4, 2013. |
