Title | |
Description | A self-revealing finding of very low safety significance was identified on February 26, 2010, because the A reactor recirculation pump (RRP) tripped. The pump trip caused a reactor coolant system transient and a decrease in reactor power. The RRP tripped due to low motor generator (MG) set lube oil pressure that occurred because PSEG had not refilled a MG set lube oil pump prior to RRP restoration after oil was drained to support lube oil pump maintenance. The performance deficiency was more than minor because it was associated with the human performance attribute of the initiating events cornerstone and adversely affected the cornerstone objective to limit the likelihood of those events that impact plant stability and challenge critical safety functions. Specifically, the failure to refill the lube oil pump with oil caused the A RRP to trip, which is defined as a transient in Hope Creek UFSAR, 15.3.1.1.2.1. As stated in the IMC 0612, Appendix E, more than minor example 4.b, a performance deficiency is, \"not minor if: The error caused a reactor trip or other transient.\" The inspectors performed a Phase I screening of the finding in accordance with IMC 0609.04, \"Phase I - Initial Screening and Characterizing of Findings.\" The finding screened as Green (very low safety significance) because the finding did not contribute to both the likelihood of a reactor trip and the likelihood that mitigation equipment or functions would not be available. The finding had a cross-cutting aspect in the area of human performance, because PSEG did not appropriately coordinate work activities (H.3(b)). Specifically, PSEG maintenance did not coordinate the change to the work plan with PSEG operations. |
