| Title | FAILURE TO MONITOR CONDENSATE FEEDWATER SYSTEM UNDER 50.65(a)(1) DUE TO INADEQUATE MAINTENANCE RULE FAILURE TRACKING |
| Description | The inspectors identified a finding of very low safety significance and non-cited violation (NCV) of 10 CFR 50.65(a)(2), Requirements for Monitoring the Effectiveness of Maintenance at Nuclear Power Plants, for the licensees failure to establish an a(1) action plan and associated goals when the condensate feedwater (CFW) system a(2) preventative maintenance demonstration became invalid. Specifically, in May 2011, the No. 12 CFW train exceeded its performance criteria when it experienced two maintenance preventable functional failures (MPFFs). The licensee failed to appropriately account for these failures in their Maintenance Rule Program and, as a result, the site failed to monitor the equipment under 10 CFR 50.65(a)(1) as required. Corrective actions taken by the licensee to address this issue included performing a root cause evaluation of the sites Maintenance Rule programmatic deficiencies; performing an extent of condition which identified several other instances where MPFFs of other systems had not been accounted for; and creating an a(1) action plan for the CFW system. These issues were entered into the licensees corrective action program as CAP 01321996, CAP 01324083, and CAP 01323429. The inspectors determined that the licensees failure to monitor the CFW system in accordance with the requirements of 10 CFR 50.65(a)(1) due to inadequately accounting for two MPFFs under 10 CFR 50.65(a)(2) was a performance deficiency, because it was the result of the failure to meet a requirement or a standard; the cause was reasonably within the licensees ability to foresee and correct; and should have been prevented. The inspectors screened the performance deficiency per IMC 0612, Power Reactor Inspection Reports, Appendix B, and determined that the issue was more than minor because it impacted the equipment performance attribute of the Initiating Events Cornerstone objective to limit the likelihood of those events that upset plant stability and challenge critical safety functions during shutdown as well as power operations. The inspectors applied IMC 0609, Attachment 4, Phase 1 Initial Screening and Characterization of Findings, to this finding. The inspectors evaluated the issue under the Initiating Events Cornerstone, and utilized Column 1 of the Table 4a worksheet to screen the finding. For transient initiators, the inspectors answered No to the question, Does the finding contribute to both the likelihood of a reactor trip AND the likelihood that mitigation equipment or functions will not be available? and determined the finding to be of very low safety significance. The inspectors determined that the contributing cause that provided the most insight into the performance deficiency was associated with the cross-cutting area of Problem Identification and Resolution, having corrective action program (CAP) components, and involving aspects associated with the licensee trending and assessing items from the CAP in the aggregate to identify programmatic and common cause problems, and communicating the results of the trending to applicable personnel |
