Title | Failure to Follow Procedure When Making Changes to Off-Normal Operating Procedure OFN NB-042 |
Description | The team identified a Green, non-cited violation of 10 CFR 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, which states, in part, Activities affecting quality shall be prescribed by documented instructions, procedures, or drawings, of a type appropriate to the circumstances and shall be accomplished in accordance with these instructions, procedures, or drawings. Specifically, in 2007 the licensee failed to follow Procedure AP 15C-004, Preparation, Review and Approval of Procedures, Instructions and Forms, when making changes to safety-related emergency diesel generator surveillance testing Procedure OFN NB-042. The technical reviewer failed to identify that the power supply for the communication equipment for the dedicated operator was from non-essential power and would be lost during a loss of offsite power event, losing the communications between the control room and the operator. The licensee has entered this issue into their corrective action program as Condition Report CR-72711. The team determined that the failure to follow Procedure AP 15C-004 when making changes to off normal operating Procedure OFN NB-042 was a performance deficiency. This finding was more than minor because it was associated with the Equipment Performance attribute of the Reactor Safety, Mitigating Systems Cornerstone, and adversely affected the cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, the licensee failed to perform a technical walk-down of the procedure steps to verify the power supply for the communication equipment would not be lost during a loss of power event. In accordance with NRC Inspection Manual Chapter 0609, Appendix A, Exhibit 2, the inspectors determined the finding was of very low safety significance (Green), because the finding was not a design deficiency and did not result in the loss of operability or functionality. This finding did not have a crosscutting aspect because the most significant contributor to the performance deficiency did not reflect current licensee performance. |
