1 Manually shutdown the unit due to a socket weld leak on the RCS pressure boundary upstream of valve SIA-V056.
SUMMARY
- The unit began month in Mode I with RX power at 99.1 1%. On 02/03104 an RCS pressure boundary was discovered and the unit commenced a controlled downpower to 20%. The RX was manually tripped at 20% per RX shutdown procedure. After repair the unit went critical on 02/07/04 and the main generator was synchronized on 02/08104. Full RX power was reached on 02/09/04. The unit ended the month in Mode I with RX power at 99.02%

1 Manually tripped RX per shutdown procedure at 20% power due to SG#1 tube leak.
SUMMARY
- The unit began month in Mode I with RX power at 99.87%. On 02119/04 a small tube leak was detected on SG#1 and the unit commenced a controlled downpower to 20%. The RX was manually tripped at 20% per RX shutdown procedure and the unit was cooled down to Mode 5 for cause analysis and plugging of the affected tube.
The unit ended month in Mode 5.
Unit was uprated during the last refueling outage. Unit capacity appears to have increased by approximately 92 MW, however, previous values of Design Electrical Rating and Maximum Dependable Capacity will continue to be used until new capacity values are determined.

1 Automatic turbine trip on loss of generator field due to an excitation control system failure. Following turbine trip the RX was manually shutdown.
SUMMARY
- The unit began the month in Mode I with RX power at 98.60%. On 02/28/04 the main turbine generator tripped, immediately followed by an automatic RX power cutback. The cause of the turbine trip was the loss of the generator field due to an excitation control failure. The unit commenced a downpower to 20% to troubleshoot the excitation problem. The RX was manually tripped at 20% per RX shutdown procedure. On 02/29/04 during a walkdown of the RCS a small leak was found at one of the pressurizer heater sleeves. The unit commenced a cool down to Mode 5 and ended the month in Mode 4.
