| Title | Failure to Assure that Adequate Test Requirements Were Developed and Implemented Following a Repair |
| Description | The inspectors identified a NCV of TS 5.7.1, Procedures, for the licensee failing to develop and implement an adequate post-maintenance test procedure for valve 0-CKV-067-0502C, air release valve for C ERCW pump, resulting in the valve not being fully tested following rebuild per work order (WO) 07-820358-000. The licensee entered these issues into the corrective action program as PER 228680 The licensees failure to develop and implement an adequate post-maintenance test was determined to be a performance deficiency. The performance deficiency was determined to be more than minor, and therefore a finding, because it would have the potential to lead to a more significant safety concern if left uncorrected, in that, failing to ensure that adequate procedures are developed and implemented could allow risk-significant equipment to unknowingly be returned to service in a degraded condition. This finding was evaluated using the Significance Determination Process Phase 1 screening criteria and was determined to be of very low safety significance because the finding did not represent an actual loss of safety function of a single train of equipment for greater than its TS allowed outage time. The cause of the finding had a cross-cutting aspect in the area of human performance associated with the work control component. It was directly related to the licensee appropriately coordinating work activities by incorporating actions to address the impact of changes to the work scope on the plant H.3(b). Specifically, personnel failed to recognize the impact of changing the scope of the PMT. As a result, an inadequately tested valve was placed into service. |
