The inspectors identified a
NCV of
10 CFR 50, Appendix B, Criterion XVI, Corrective Actions, because
PSEG failed to identify and correct a
condition adverse to quality. Specifically,
PSEG did not identify that the
high pressure coolant injection (
HPCI) booster pump outboard bearing housing oil level was below the minimum level mark, and the housing was actively leaking. Corrective actions performed by
PSEG included restoring the proper oil level, repairing the leak, conducting training for equipment operators, and performing observations of equipment operator rounds. The violation was entered into the corrective action program as notification 20444949.The inspectors determined that not identifying a
condition adverse to quality. The lowering oil level in the
HPCI booster pump outboard bearing that could have prevented the
HPCI system from performing its safety function, was a performance deficiency. The performance deficiency was more than minor because, if left uncorrected, the
condition adverse to quality would
lead to a more significant safety concern. The inspectors performed a Phase I screening of the finding using
IMC 0609, Attachment 0609.04,Table 4a,
Mitigating Systems cornerstone. The inspectors determined the issue was of very low safety significance (Green) because the finding was not a design or qualification deficiency, did not result in an actual loss of safety function, and was not potentially risk significant for external events. The finding had a cross-cutting aspect in the area of problem identification and resolution (
PI&R), because
PSEG did not identify the
HPCI booster pump bearing low oil level condition and leak completely, accurately, and in a timely manner commensurate with its safety significance.
