| Title | Handling of Diesel Generator Problems by CAP |
| Description | No significant concerns were identified with the licensees assessment of the individual failures. However, the team determined that additional questions remained concerning the licensees approach to identifying a degrading trend in EDG performance. After the sixth MSPI failure in August 2005, the licensee initiated AR 166409 to follow up on the failures and determine any areas for additional effort. This AR identified that there was a degrading trend in EDG performance. However, instead of an NCR, which would have required a root cause investigation and corrective actions to prevent recurrence, the licensee issued AR 166409 as a self-assessment. Later, in November 2005, the licensee changed it to a bench marking report. In addition to this use of a bench marking report, the team determined that weaknesses in the corrective action program (CAP) constituted a missed opportunity to correct preventive maintenance and human performance issues that affected the availability and reliability of the EDGs. The team reviewed several ARs that documented the licensees previous failures to take adequate corrective actions to address weaknesses in these two areas. This review showed that the inadequacy of previous corrective actions was identified by the corporate and site nuclear assurance sections (NAS). The team noted that while new ARs were initiated to address the recurring preventive maintenance and human performance issues, no evaluation(s) or corrective action(s) addressed the failure of the CAP to effectively deal with the previously identified deficiencies. The licensee did have open corrective active actions to address preventive maintenance and human performance issues that were originally identified in 2003 and 2004. The licensees ARs related to these issues are listed below. AR 102339 (2003), WANO Peer Review Shortfalls in Preventive Maintenance AR 129173 (2004), Maintenance Adverse Trend in Human Performance AR 135289 (2004), PES Issue for Plant Performance AR 169120 (2005), NAS Weakness in Equipment Reliability Process AR 206696 (2006), 2006 INPO Midcycle - Gap in Preventive Maintenance AR 204325 (2006), NAS Assessment - Conduct of Maintenance These items will remain unresolved pending further inspection of the impact they had on the continuing problems with the EDGs. This will include licensee handling of both AR 166409 and the previously identified preventive maintenance and human performance problems. This matter is identified as Part 1 of URI 05000325, 324/2007010-01, Handling of Diesel Generator Problems by the CAP. |
