Monthly Report for Braidwood Unit 1 A.

Summary of Ooeratina Experience The unit entered the month of August at 99% reactor power. On August 11, a reactor trip occurred while replacing a fuse on the Rod Control System.

The unit was returned to service on August 12. On August 21 power was reduced to less than 50% to evaluate the Quadrant Power Tilt Ratio following load swings ordered by the Load Dispatcher.

The unit was returned to 98% reactor power on August 22 and remained at that level through the end of the month, r.

II. Monthly Report for Braidwood Unit 2 A.

Summarv of Ooeratina Exoerience The unit entered the month of August at 74% reactor power. On August 7, power was reduced to below 50% to facilitate Feedwater Pump startup testing.

Following this testir.g the unit 'vas returned to 74% reactor power on August 8.

1he unit was again reduced below 50% reactor power on August 13 to facilitate Feedwater Pump testing.

On August 15, the unit was returned to 70% reactor power.

On August 17, the 75% startup test sequence was completed and the unit was increased to 90% reactor power. On August 23, power was reduced t 26% as a result of a nitrogen leak on a Feedwater Isolation Valve. Upon completion of repairs, the unit was increased to 90%

reactor power. On August 31, the 90% startup test sequence was completed and the unit was increased to 100%

reactor power.
