SUMMARY

LaSalle Unit 1 operated at full power for the month of August 2003, with the exception of the following:

August 2 - Power was reduced to about 1005 MWe to enable recovery of condensate booster pump suction pressure during isolation of the 14B feedwater heaters. The feedwater isolation was due to a failure of the solenoid for the 16 A heater normal drain valve. The solenoid was replaced and the unit was returned to full power on August 3, 2003.

August 30 - Power was reduced to about 600 MWe for control rod pattern adjustment and rod testing. The unit was returned to full power on September 1, 2003.

C. UNIQUE REPORTING REQUIREMENTS FOR UNIT ONE

1. Challenges other than routine surveillance testing to Safety/Relief Valve Operations-None

2. Major Changes to Radioactive Waste Treatment System-None
