Title | Equipment Out-of-Service Log Definitions Redefined Outside of Procedure Change Process |
Description | The inspectors identified a noncited violation of Technical Specification 5.4.1.a, procedures, for changing the equipment out-of-service log outside of the procedure change process. On November 25, 2008, the inspectors questioned the status of excess letdown Valve 8153B because its equipment out-of-service log entry changed from available to unavavailable. The inspectors were informed that the meaning of unavailable was verbally changed to mean that the valve was inoperable but considered available. This contradicted the words of the electronic log and Procedure AP 21F-001, Equipment Out of Service Control. Operations management was aware of the change to the terminology. Inspectors reviewed Procedures AP 21F-001 and found it required a senior operator to make and maintain the equipment out-of-service log. Procedure AP 15C-004, Preparation, Review and Approval of Procedures, Instructions and Forms, defines AP class procedures as those that, in part, implement activities that can significantly affect nuclear safety. Inspectors did not identify any other formal change processes that led to the log changes. Inspectors found no formal training or communication to all licensed and nonlicensed operations staff on this change. The failure to implement AP 21F-001was considered a performance deficiency. The finding was determined to be more than minor because it could become a more significant safety concern if procedures and configuration controls are changed outside the required process. The inspectors evaluated the significance of this finding under the mitigating systems cornerstone using Phase 1 of Inspection Manual Chapter 0609.04, Phase 1 Initial Screening and Characterization of Findings, and determined that the finding was of very low safety significance (Green) because no systems, structures, or components were inappropriately out of service for greater than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> due to errors in the log. Specifically, no equipment status was lost such that it was returned to service inappropriately. Further, none of the affected equipment was risk significant for the mitigation of external events such as flooding. The inspectors determined that this finding has a crosscutting aspect in the area of Human Performance associated with the Decision Making component because Wolf Creek did not use its procedure change process to demonstrate that changing the equipment out service log the change was a safe course of action. Although roles and authority are defined in Procedure AP 15C-004, these roles and authorities were not implemented for a safety significant decision H.1.a] (Section 4OA2) |
