Title

Unit 1 Train B Auxiliary Feedwater Pump Diesel Fire and Shutdown During Surveillance

Description

On March 21, 2008, during a routine 18 month surveillance test, the operator in the room reported that the diesel was on fire. The diesel driven pump was shut down and declared inoperable resulting in the licensee entering 72 hour8.333333e-4 days 0.02 hours 1.190476e-4 weeks 2.7396e-5 months shutdown Limiting Condition for Operation 3.7.5. Subsequently the licensee performed a planned shutdown for a refueling outage, exiting the applicable modes and negating the need to repair the diesel within 72 hours8.333333e-4 days 0.02 hours 1.190476e-4 weeks 2.7396e-5 months . The refueling outage continued past the end of the inspection report period. The inspectors observed plant personnel responding to an unexpected fire during the surveillance test. The inspectors were in the control room to observe the surveillance test when a fire developed at the AF diesel engine. The inspectors responded to the diesel engine room and observed the fire brigade activities and subsequent operability determination of the AF pump. At the close of the inspection period additional information was required to determine if the failure of the 1B was acceptable, was a finding, or if it constituted a deviation or violation. Additional information needed included the results of the licensees cause evaluation and proposed corrective actions. Based on the root cause of the fire a possible performance deficiency existed and the cause analysis would assist the inspectors in making such a determination. Documents reviewed are listed in the Attachment. (URI 05000455/2008002-04
