Operators at Peach Bottom Atomic Power Station returned Unit 3 to service at 9:47 a.m. ET Oct. 22 after completing a planned refueling and maintenance outage that began on September 21.
During the outage, Exelon employees and skilled craft workers installed new equipment; upgraded plant components; and performed tests and inspections to ensure safe and reliable operation for another two-year cycle. The majority of this work cannot be performed while the unit is generating electricity.
“Peach Bottom has a proud history of effective refueling outages, and this year was no different,” said Site Vice President Mike Massaro. “We completed a number of significant upgrades this year that will allow us to continue providing safe and reliable power to the region for years to come.”
Over the last five years, most of Peach Bottom’s major components have been replaced or upgraded as part of Exelon’s extended power uprate (EPU) project. This includes the station’s high and low-pressure turbines, steam dryers, generators and main power transformers. When the project is completed next spring, Peach Bottom will be powering an additional 250,000 homes and businesses. This represents a twelve percent increase in power generation with essentially no greenhouse gas emissions.
This important work was performed by Exelon specialists and more than 2,500 highly skilled supplemental workers, many of whom live, eat and shop locally, providing a significant boost to the local economy prior to the winter season.
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 generating 2,700 megawatts combined. Both reactors began commercial operation in 1974.
