| Title | Inadequate Maintenance of the 13 AFW Pump Governor |
| Description | A self-revealing finding of very low safety significance was identified because PSEG did not implement adequate preventive maintenance for the turbine driven auxiliary feedwater (AFW) pump speed governor. Consequently, the governor oil conditions degraded causing governor binding and speed oscillations that required the 13 AFW pump to be tripped during testing, resulting in unavailability of the 13 AFW pump. PSEGs corrective actions included replacement of the 13 AFW pump governor, increased oil sampling and oil replacement for the AFW pump governors, and a reduction in the governor replacement periodicity from 90 to 72 months. This finding was more than minor because it was associated with the equipment performance attribute of the Mitigating Systems cornerstone and because it affects the associated cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, the 13 AFW pump was unavailable for 46 hours5.324074e-4 days <br />0.0128 hours <br />7.60582e-5 weeks <br />1.7503e-5 months <br /> following the oscillations observed during the quarterly surveillance test. The inspectors conducted a Phase 1 screening of the finding in accordance with IMC 0609, Attachment 0609.04, Initial Screening and Characterization of Findings, and determined that the finding was of very low safety significance (Green). The inspectors did not identify a cross-cutting aspect associated with this finding because decisions made associated with the preventive maintenance change occurred several years ago and were not reflective of current performance. The preventive maintenance change request process has been replaced with the equipment reliability process and the performance centered maintenance (PCM) process. PCM templates have operating experience and vendor recommendations integral to the template, not merely listed as procedure references, which was the case with previous equipment reliability procedures |
