TABLE 3 - REMARKS 11 - Within 30 min after the trip, No. 1 EDG was successfully restarted, loaded and shutdown (Startup Testing).
12 and 13 - Within 8 hrs and 30 min after tripping on overspeed, No. 2 EDG was restarted and failed again due to an apparent synchronization circuit fault. Af ter approximately 6 hrs repair time, no fault was found. The generator was then started, loaded and shutdown successfully (Mode 5).
14 - Within 3 hrs after tripping while reenergizing one train of the SSPS, No. 2 generator was started, locded, unloaded and shutdown successfully.
The generator was successfully started and stopped three additional times (Mode 5).
15 - Diesel No. 2 tripped while reenergizing "B" train SSPS. Subsequently, diesel No. 2 received a start signal but would not start due to an abnormal lineup of the 125 V de system during a battery test.
No. I diesel was put on line, thus supplying the needed de to bring No. 2 diesel to speed (Mode 5).
16 - Within 4 hrs 10 min after trip on overspeed, it was found that No. 2 EDG's field had shorted.
It was repaired, started and shutdown successfully (Mode 6).
17 - Within 48 min af ter emergency shutdown due to a fire in the exhaust stack, No. 2 diesel was restarted, loaded, unloaded and shutdown successfully (Mode 6).
18 - Within 13 hrs af ter No. 2 diesel unloaded due to broken limit switches in the governor, repair was made and the diesel was started and shutdown successfully (Mode 5).
