From Nuclear Street:
Operators at Exelon Nuclear’s Peach Bottom Atomic Power Station safely shutdown the Unit 3 reactor yesterday 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.
Peach Bottom has six main power transformers, four of which have already been replaced as part of Exelon’s $87 million investment to ensure 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, 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.
