Peach Bottom Atomic Power Station Unit 2 July 1 through July 31, 2003 Narrative Summary of Operating Experiences Unit 2 began the month of July at 100% power.

At 2300 on July 1 9'h, Unit 2 reduced power to 93% for planned turbine testing, and to swap lube oil coolers on the 2C reactor feedpump turbine. The Unit returned to 100% power by 0200 on July 201.

At 1345 on July 22"d, Unit 2 automatically scrammed from 100% power, due to a generator lockout and resulting turbine trip. At 1358, a Group I isolation occurred due to rising steam tunnel temperatures. During the ensuing forced outage, both the scram and the Group I isolation were investigated. The cause of the scram has been identified to be foreign material in the ISO phase bus duct, which caused intermittent generator grounds. Following corrective actions, the Unit reached critical operation at 0614 on July 25t, and was synchronized with the grid at 1016 on July 26th. Due to previously identified leaking fuel, the power ascension was limited to approximately 0.7% per hour. The Unit reduced power to 50% for a follow-up load drop to set the final rod pattern on July 30'. The Unit returned to 100% power by 2300 on July 31'8.

Unit 2 ended the month of July at 100% power.

Peach Bottom Atomic Power Station Unit 3 July 1 through July 31, 2003 Narrative Summary of Operating Experiences Unit 3 began the month of July at 100% power.

At 2300 on July 5', Unit 3 reduced power to 72%, for a planned rod pattern adjustment. The Unit returned to 100% power by 0643 on July 6 .*

Unit 3 ended the month of July at 100% power.
