LACEY TOWNSHIP — The Oyster Creek Nuclear Generating Station, set to close permanently Sept. 17, is operating at reduced power because of a water leak, according to the Nuclear Regulatory Commission.
“This is due to feedwater heater tube leakage,” NRC spokesman Neil Sheehan said Thursday. “The plant remains stable and our resident inspectors assigned to Oyster Creek are continuing to monitor operators’ response to the condition.”
It has cut back to 70 percent power, Sheehan said.
But Exelon spokesperson Tammy Holden said Friday the plant is just "coasting down" in anticipation of next month's closing and minor maintenance is being done.
Feedwater is water that is circulated through the steam cycle as it comes out of the condenser and is sent into the boiler. Feedwater heaters preheat the water to decrease the heating time in the boiler and increase the plant’s overall efficiency, according to Minnesota State University.
