Dresden Generation Station’s Unit 2 automatically came offline today at 12:28 p.m. CT, after station operators received an indication of a momentary power interruption to a system that monitors reactor water level for the unit. Power to the system was restored within seconds, and the unit responded as designed.
Station technical experts are looking into the cause of the interruption. While the unit is offline, plant personnel will perform maintenance that cannot be done while the unit is operating.
Dresden Unit 3 continues to operate at full power.
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.
