During the review of corrective actions related to previous December 2009 NCV 05000390/2009005-01, Failure to Implement Analysis for Failed Auxiliary Charging Pumps, the inspectors determined that no documentation of acceptable testing could be found which verified the functionality of the auxiliary charging pumps (ACPs) 1A and 1B until March 23, 2012. During that testing, which was observed by the inspectors, only the 1B ACP met its acceptance criteria,1A ACP failed. The flood mode boration makeup system relies on the capability of these pumps to support Technical Requirement 3.7.2, Flood Mode Protection Plan. Pending additional information from the licensee which can verify the adequacy of the AIST program corrective action for the auxiliary charging pumps, this item is identified as unresolved item (URI) 050000390/2012002-04, Failure to Demonstrate Corrective Actions for the Auxiliary Charging Pumps.
