Major Upgrades at Constellation Nuclear Stations Ensure Carbon-Free Electricity for 15 Million This Summer
Over 13,000 workers supported maintenance projects during spring refueling outages to keep power supplied 24/7 during hot summer months and beyond
During the refueling outages, workers replaced or refurbished dozens of pumps and motors, performed quality assurance inspections on reactor and fuel components, and completed tens of thousands of other technical tasks to ensure the power plants provide uninterrupted carbon-free electricity for up to 24 straight months.
“Constellation is helping accelerate this country’s transition to a carbon-free future and it begins with our zero emissions nuclear fleet running nonstop through the summer,” said
This summer, nuclear reliability could be especially helpful in moderating electricity prices for
The refueling outages would not be possible without support from thousands of skilled electricians, pipefitters, welders, carpenters, laborers, steamfitters and other trades people on site performing thousands of inspections, tests and maintenance activities that cannot be done while the unit is online. Along with replacing about one-third of the fuel in each reactor, workers completed other major projects during the nuclear outages this spring, including:
Illinois, workers at Quad Cities Unit 2 performed an overhaul and inspection of the turbine on one of the redundant core cooling systems; a full technical inspection of the Byron Station Unit 2 main generator; and a comprehensive inspection of two reactor recirculation flow control valves at LaSalle County Generating Station.
In the east, workers at
Calvert Cliffs Stationin Marylandreplaced the Unit 1 main generator connections. At Limerick Stationin southeastern Pennsylvania, technical experts performed a full inspection of the main turbine. At Nine Mile Pointin upstate New York, workers replaced all four of the Unit 2 main power transformers, improving the station’s ability to maintain safe, reliable, carbon-free power for the upstate New Yorkarea.
“We carefully schedule these important upgrades, maintenance activities and technical inspections during periods of lower power demand to ensure our carbon-free nuclear units remain online 24/7 through the blistering summer months ahead,” said
