Peach Bottom nuclear Unit 3 in Pennsylvania returned to service after completing a planned refueling and maintenance outage that began September 21. The dual-unit power plant generates 2,700 MW of electricity.
During the outage, Exelon (NYSE: EXC) workers installed new equipment, upgraded plant components, and performed tests and inspections to ensure reliable operation for another two-year cycle.
Most of Peach Bottom’s major components have been replaced or upgraded over the last five years as part of Exelon’s Extended Power Uprate project. These parts include the plant’s high and low-pressure turbines, steam dryers, generators and main power transformers. When the EPU is completed next spring, the generating capacity of the two boiling water reactors will increase 12 percent.
