| Title | Failure to provide adequate maintenance instructions |
| Description | The team reviewed a non-cited violation of Technical Specification 5.4.1.a, Procedures, for the licensees failure to provide maintenance instructions appropriate for repair of the Train B emergency diesel generator supply fan. These inadequate instructions resulted in maintenance technicians routing and restraining electrical cables inappropriately during maintenance in July 2006. These cables later came loose and, in August 2011, caused a failure of the Train B emergency diesel generator supply fan to start on demand. The failure to provide maintenance procedures appropriate to the circumstance was a performance deficiency. This finding was more than minor because it affected the equipment performance attribute of the Mitigating Systems Cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Using Inspection Manual Chapter 0609.04, Phase 1 Initial Screening and Characterization of Findings, the team determined that the finding was of very low safety significance (Green) because it did not result in the loss of the safety function of any system or train and did not screen as potentially risk significant due to seismic, flooding, or severe weather initiating events. The team determined that this performance deficiency was not indicative of current plant performance because it was the result of repair instructions written and implemented in 2006. Therefore, no cross-cutting aspect was assigned. |
