| Title | Failure to Adequately Install an Oil Collection System on Reactor Coolant Pump Motors |
| Description | An NRC-identified, non-cited violation of 10 CFR 50.48(c) and National Fire Protection Association Standard 805 (NFPA 805), Section 3.3.12, was identified for the licensees failure to comply with code requirements for design and installation of the Unit 1 Reactor Coolant Pump (RCP) oil collection system. The oil collection system did not include drain troughs that would collect leakage from all leakage points. The licensee installed new oil collection drain troughs to capture potential leakage, and entered the issue into the corrective action program as CR10064368 and CR10064530. The failure to install drain troughs for the Unit 1 RCP oil collection system that would capture leakage from all potential leakage points was a performance deficiency (PD). The PD was more than minor because it was associated with the protection against external factors (i.e., fire) attribute of the Mitigating Systems cornerstone and adversely affected the cornerstone objective. Specifically, the inadequate installation of the RCP oil collection system was a degradation of a fire prevention function to not allow an oil leak to reach hot surfaces. The significance of this finding was of very low safety significance (Green) because the exposed fire area contains no potential damage targets that are unique from those in the exposing fire area. The inspectors determined the finding had a cross-cutting aspect of Evaluation in the Problem Identification and Resolution area (P.2) because a previous extent of condition review performed in corrective action report (CAR) 218579 on December 15, 2014, incorrectly concluded that the Unit 1 design did not require the drain troughs. |
