| Title | Unplanned Unavailability of the Motor Feedwater Pump After it was Placed in 10 CFR 50.65(a)(1) status |
| Description | An Unresolved Item (URI 05000440/2008005-05) was opened related to unplanned unavailability of the motor feedwater pump (MFP) after it was placed in 10 CFR 50.65(a)(1) status. The licensee determined that the feedwater system met 10 CFR 50.65(a)(1) status on January 31, 2008, because system unavailability exceeded established performance criteria. Events that contributed to unavailability included two losses of feedwater associated with the feedwater digital control problems and four occasions of water intrusion into the MFP lube oil system in 2007. The licensee implemented corrective actions and goals to assure that the feedwater system was capable of fulfilling its intended functions. On March 29, 2008, and on August 7, 2008, the MFP again was rendered unavailable due to water intrusion into the MFP lube oil system. On October 14, 2008, the licensee decided to extend a corrective action to replace a MFP seal from December 2008 to April 2009. Due to the repeated MFP unavailability events after the system was placed in 10 CFR 50.65(a)(1) status, the inspectors were concerned whether the licensee\\\'s corrective actions were appropriate. The inspectors determined this issue required further review |
