| Title | Units 1 and 2 Station Battery Cable Installation Issues |
| Description | A URI was identified by the inspectors relating to an issue involving the installation of cabling associated with the emergency DC bus station batteries for each of the 4 channels on Units 1 and 2. On November 17, 2009, the licensee initiated CR358461 for NRC-identified issues relating to installation of cabling associated with the emergency DC bus station batteries for each of the 4 channels on Units 1 and 2. Specifically, the cables did not appear to meet vendor installation requirements for the cables such that the battery posts do not bear the load. The licensee completed an operability determination, OD000347, which used the Seismic Qualification Utility Group process to determine the batteries were operable but not fully qualified; however, the inspectors review of this document has not been completed. Additionally, licensee engineering evaluation of their installation relative to vendor requirements is also ongoing. The inspectors require additional information from the licensee to determine if there is a performance deficiency which is greater that minor. This issue is identified as URI05000338, 339/2009005-03, Units 1 and 2 Station Battery Cable Installation Issues. |
