Peach Bottom Unit 3 has reached a new power generation milestone of 1,355 megawatts, following the successful completion of an extended power uprate (EPU) that began in 2009. EPU projects are sanctioned by the Nuclear Regulatory Commission (NRC) and require extensive design reviews, as well as upgrades to plant components and safety systems.
Since 2009, Exelon has been working with the NRC to finalize the EPU design review and perform the equipment upgrades. Peach Bottom's EPU application called for replacing the high pressure turbines, feed pump turbines, condensate pumps and motors, and steam dryers on both units. The station's low-pressure turbines, main power transformers and main generators had already been upgraded in support of the EPU project. These upgrades required the skills of thousands of employees, contractors and technicians, many of whom support local businesses while in the area.
Peach Bottom Atomic Power Station is located on the west bank of the Conowingo Pond (Susquehanna River) in York County, Pa.The station is home to two boiling water reactors, capable of powering more than 2.25 million homes and businesses. Both reactors began commercial operation in 1974.
