Delta, Pa., November 16, 2010 – Operators at Exelon Nuclear’s Peach Bottom Atomic Power Station safely shutdown the Unit 3 reactor today at 8 a.m. ET to allow workers to replace one of the station’s main power transformers.
Station operators, who continuously monitor plant performance, made the determination to replace the transformer this weekend as a precaution.
The station’s Unit 3 “˜B’ transformer, one of two remaining units that have been in service since 1974, will be replaced with a spare unit of similar vintage that is currently on site. Both older transformers are scheduled for replacement next fall.
Station operators will take advantage of the outage to complete a host of other maintenance tasks that can only be performed while the unit is offline.
Peach Bottom’s Unit 2 reactor is not affected and will continue to run at full power during the transition. The station is home to two boiling water reactors, which jointly produce over 2,200 MW of electricity, powering more than two million homes.
Exelon distributes electricity to about 5.4 million customers in northern Illinois and southeastern Pennsylvania and natural gas to about 486,000 customers in the Philadelphia area. Exelon is headquartered in Chicago.
