Operators at Dresden Generating Station returned Unit 2 to full power operation Friday night Feb. 13 following maintenance on a system that controls the water level in the reactor.
While the unit was offline, plant personnel completed additional maintenance activities including replacing four relief valve actuators and other work that cannot be performed while the unit is operating.
Unit 2 automatically shut down on Feb. 6, when the water level control system experienced a momentary power interruption. The unit was placed back in service on Thursday, Feb. 12.
Dresden Generating Station is approximately 60 miles southwest of Chicago. The station’s two nuclear energy units can produce more than 1,900 megawatts at full power – enough carbon-free electricity to power more than 1.2 million typical homes. Dresden Unit 1, which began commercial operation in 1960 and was retired in 1978, has been designated a Nuclear Historic Landmark by the American Nuclear Society.
