| Title | Failure to Conduct an Adequate Risk Assessment for an Orange Risk Condition |
| Description | The inspectors identified a Green NCV of 10 CFR 50.65 (a)(4) for the licensees failure to manage the increase in risk by minimizing the plants exposure to elevated risk during the 1R20 refueling outage. Specifically, during the first period of reduced inventory after shutdown with a reduced time-to-boil, the licensees failure to appropriately manage and execute maintenance activities led to extended time being spent in the reduced inventory condition. Later in the outage, two unplanned entries into reduced inventory were required to diagnose and correct issues stemming from the D Primary coolant pump impeller replacement. The licensee entered this issue into their corrective action program as Condition Report (CR)-PLP-2009-03392.The inspectors determined that a significant portion of the additional time spent in reduced inventory was within licensee control. The issue is greater than minor in that the licensee failed to manage activities in such a way as to minimize the time spent in reduced inventory. The inspectors determined the finding impacted the Initiating Events cornerstone whose objective is to, in part, limit those events that upset plant stability. The finding is of very low safety significance (Green) using Appendix M because it did not involve a loss of control nor did it require a quantitative analysis per IMC 0609 Appendix G, Attachment 1. The inspectors concluded that this finding has a cross-cutting aspect in the area of human performance because a primary cause of the finding is associated with the human performance cross-cutting component of work practices, in that the licensee failed to provide appropriate oversight for work activities consistent with nuclear safety. |
