| Title | Failure to Correctly Reassemble a Motor Operated Valve |
| Description | The inspectors identified a non-cited violation of Technical Specification 5.4.1.a for the failure to follow procedure and correctly restore motor operated valves. As a result, the licensee inverted the Unit 1 power operated relief valve block valves limit switch covers and placed the drain on the top. The licensee entered the finding into the corrective action program as Condition Report CR-2011-011871. The inspectors identified a non-cited violation of Technical Specification 5.4.1.a for the failure to follow procedure and remove items from containment. As a result, maintenance personnel failed to remove materials that could be transported to the containment emergency core cooling sumps during an accident. The inspectors informed the licensee of the debris inside containment and the licensee corrected the condition. The licensee entered the finding into the corrective action program as Condition Report CR-2011-013343. The failure of the maintenance personnel to follow procedure and remove materials from containment was a performance deficiency which resulted in debris remaining in containment. The finding was more than minor because it was associated with the equipment performance attribute of the mitigating systems cornerstone and adversely affected the cornerstone objective to ensure the availability, reliability, and capability of the emergency core cooling sumps. Using NRC Manual Chapter 0609, Attachment 4, Phase 1 - Initial Screening and Characterization of Findings, the finding was determined to be of very low safety significance because the finding did not represent an actual loss of safety function of the emergency core cooling sumps. The finding has a human performance crosscutting aspect associated with resources because the licensee failed to ensure that personnel performing the maintenance activity were adequately trained on the procedure requirement to remove the materials when leaving containment |
