Peach Bottom back in service

Exelon Nuclear’s 2,200 MW Peach Bottom nuclear power plant’s Unit 3 was returned to service November 23 after a five-day maintenance outage. During the outage, workers replaced one of the station’s main power transformers and performed a number of maintenance tasks.

Four of the plant’s six main power transformers have already been replaced as part of Exelon’s $87 million investment to advance long-term equipment reliability at the station. The station’s Unit 3 “B” transformer, one of two remaining units that have been in service since 1974, was replaced with a spare unit of similar vintage. The replacement unit will remain in service until the station’s two new transformers are placed in service next fall.

Peach Bottom’s Unit 2 reactor ran at full power during the transition.
