SUMMARY

Unit began month at full power. On 6/14 an automatc RX trip occurred due to a major grid distrubance casuing a loss of off-site power. The RX was taken critical on 06118 and synchronized to the grid at 15:13. On 6/20 RX power reached 100%. Condensate pump B tipped on 6121 resulting in reactor power cutback to 60% power. Power ascension back to full power commenced on 6/21 and the unit reached full power on 6/23. The unit ended the month at full power.

3 RX trip due to loss of off site power caused by major grid disturbance.

SUMMARY

The Design Electrical Rating (DER) and the Maximum Dependable Capacity (MDC) reflect the power uprate performed in 2003. These are interim values. Official values approved by station owners will be determined after testing is completed at the end of the 3rd quarter (iate summer). Unit began month at full power. On 6/14 an automatic RX trip occurred due to a major grid distrubance casuing a loss of off-site power. The RX was taken critical on 06/18 and synchronized to the grid at 2310. On 6/20 RX power reached 100%. The unit ended the month at full power.

SUMMARY

Unit began month at full power. An automatic RX trip on low DNBR occurred on 6/07 due to a turbine control system anomaly. The RX was taken critical on 6109 and the unit was synchronized on 6/11 after extensive turbine control system troubleshooting. Full power was achieved on 6113. On 6/14 an automatic RX trip occurred due to a major grid distrubance casuing a loss of off-site power. The RX was taken critical on 06119 and synchronized to the grid on 06120 at 1832. On 6121 RX power reached 100%. The unit ended the month at full power.
