Duke Energy takes Oconee 3 offline to fix problem

Duke Energy (NYSE:DUK) confirmed Feb. 2 that it has temporarily taken its Oconee 3 nuclear unit in South Carolina offline in order to address an issue detected over the weekend.

“Unit 3 was manually tripped on Saturday afternoon [Jan. 31] by plant operators due to fluctuations in feedwater indications,” a Duke spokeswoman said Feb. 2 in response to a GenerationHub inquiry.

“The operators responded as expected to this type of event to place the unit in a safe condition. At no time was there any impact to the public or employees. The unit will be restarted once repairs and testing are complete,” the plant spokesperson said.

Oconee is a three-unit pressurized water reactor (PWR) facility located in Seneca, S.C. Each of the units has an operating capacity of roughly 850 MW, according to GenerationHub data.

Both the other units at Oconee continue to run at 100% generation, according to the latest reactor status report from the Nuclear Regulatory Commission (NRC).
