On January 25, 2003 at 1414 hours with Uni … On January 25, 2003 at 1414 hours with Unit 2 at 100% power, the reactor tripped due to turbine trip from a main generator trip. The main generator trip was due to Main Transformer and Generator Leads current differential lockout. The differential lockout resulted from a shorted main generator current transformer (CT) lead. Emergency systems functioned as required for the Unit 2 trip. At the time of the Unit 2 reactor trip, Unit 1 was off-line. Load shed occurred on the Unit 1 station service busses as designed. The Unit 1 'B' Main Feed Pump tripped, and since the Unit 1 'A' Main Feed Pump had previously been shut down, a start signal was initiated to both Unit 1 Motor Driven Auxiliary Feedwater Pumps (MDAFWPs) at approximately 1414 hours. The damaged CT leads were repaired. Inspection of like components on Units 1 and 2 was performed, and repairs made as necessary. The automatic actuation of the Unit 2 reactor trip, the actuation of Unit 2 Auxiliary Feedwater, and the automatic actuation of Unit 1 Auxiliary Feedwater are reportable in accordance with 10 CFR 50.73(a)(2)(iv)(A).accordance with 10 CFR 50.73(a)(2)(iv)(A). +
