| Title | Failure to Replace an Essential Chiller Oil Pump prior to the Vendor Service Life |
| Description | A self-revealing, non-cited violation of Technical Specification 6.8.1.a. occurred because the licensee did not develop a preventative maintenance schedule to inspect or replace an item that has a specific lifetime. Specifically, the licensee did not develop a preventative maintenance schedule to inspect or replace the essential chiller oil pump motors prior to exceeding their duty life. As a result, the essential chiller oil pump B motor failed in-service. The licensee entered this condition into their corrective action program as Condition Report CR-WF3-2014-0095. The immediate corrective action taken to restore compliance was to issue an action request to establish the periodic replacement of the essential chiller oil pumps prior to the end of their vendor recommended service life. The inspectors concluded that the failure to develop a preventative maintenance schedule to inspect or replace the essential chiller oil pump motors prior to the end of the vendor provided duty life was a performance deficiency. The performance deficiency was more than minor because it was associated with the equipment performance attribute of the mitigating systems cornerstone and adversely affected the cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, it affected the availability and reliability of the essential chillers to provide a heat sink for the removal of process and operating heat from selected safety-related equipment during design basis accidents. The initial screening directed the inspectors to use Inspector Manual Chapter 0609, Appendix A, The Significance Determination Process for Findings At-Power, Exhibit 2, Section A, to determine the significance of the finding. The inspectors categorized the finding as having very low safety significance (Green) because the finding did not affect the design or qualification of the system; it did not represent a loss of the system or function; and, the loss of the essential chiller was less than the technical specification allowed outage time. The inspectors also concluded that the finding did not have a cross-cutting aspect because the most significant contributor to the performance deficiency occurred more than 3 years ago, and did not reflect current licensee performance. |
