| Title | Emergency Diesel Generator 3 Slow Start |
| Description | On October 14, 2012, the licensee was running EDG 3 for a zero oil pressure start test in accordance with Procedure 0PT-12.2.c, No. 3 Diesel Generator Monthly Load Test. The EDG reached rated speed at approximately 38 seconds after the EDG was started and then tripped. Surveillance Requirement 3.8.1.7 requires the EDG reach rated conditions within 10 seconds. Several seconds after reaching rated speed, the EDG began to coast down due to receiving a lockout signal since full rated conditions were not achieved within the nominal time delay of 45 seconds. The licensee replaced the overspeed start emergency boost cylinder and declared the EDG operable on October 17, 2012. The inspectors are opening an URI to review the licensee\'s evaluation of the cause of the EDG failure and determine if there is a performance deficiency. The licensee entered this issue in the CAP as NCR 567016. This issue is being tracked as a URI: URI 05000325/2012005-02 and 05000324/2012005-02, Emergency Diesel Generator 3 Slow Start. |
