| Title | Failure to Implement Preventative Maintenance Procedure Replacement Schedules for Essential Service Water makeup Pump Diesel Engine Hoses |
| Description | The inspectors identified a finding of very low safety significance and an associated NCV of Technical Specification (TS) 5.4.1, ?Procedures,? when licensee personnel failed to establish and implement a preventive maintenance schedule to replace hoses on the SX Makeup (MU) pump diesel engine. Specifically, the licensee failed to implement preventive maintenance procedures that required periodic replacement of hoses on pre-established schedules in accordance with vendor recommendations and the corporate Performance Centered Maintenance (PCM) template. The licensee entered this issue into their CAP as IR 01582656, ?NRC ID [Identified] Vendor Manual Recommendation Not Being Implemented,? and 01590368, ?NRC ID ? PCM Template/Vendor Manual Recommendation,? and planned to evaluate the current maintenance strategy for maintaining flexible hoses on the SX MU pump diesel engines. The performance deficiency was determined to be more than minor because, if left uncorrected, the performance deficiency would have the potential to lead to a more significant safety concern since the failure of SX MU pump engine hoses could result in the inoperability of the SX MU pumps. The performance deficiency was also determined to be more than minor because the issue was associated with the Procedure Quality attribute of the Mitigating Systems cornerstone and adversely affected the cornerstone objective of ensuring the reliability of systems that respond to initiating events to prevent undesirable consequences (i.e. core damage.) The finding screened as having very low safety significance because it did not result in a loss of operability or functionality. Specifically, the licensee reviewed the recent history of hose inspections and instances that required hose replacement and determined no failures had occurred that resulted in an inoperable condition. The inspectors did not identify a cross-cutting aspect associated with this finding because it was confirmed not to reflect current performance due to the age of the performance deficiency. |
