Duane Arnold nuclear plant returns to operation after refueling

NextEra Energy (NYSE:NEE) completed the refueling and maintenance outage at the Duane Arnold nuclear plant in Iowa late Nov. 25, a company spokesman confirmed.

The regularly-scheduled refueling and maintenance outage had started Oct. 4. Early Dec. 1, Duane Arnold was listed at 55% generation on the Nuclear Regulatory Commission (NRC) daily reactor status report.

Duane Arnold is a boiling water reactor (BWR) with a nameplate capacity of 680 MW, according to GenerationHub data.

The NRC status report only listed two of the nation’s 100 commercial reactors at zero percent. Less than two months ago, the fall refueling outage season was in full swing and there were 17 reactors offline.

Both are located in the Southeast. One was the Duke Energy (NYSE:DUK) Oconee 1 facility in South Carolina. The other is the NextEra subsidiary Florida Power & Light (FPL) Turkey Point 4 in Florida.

Turkey Point 4 underwent a “planned reactor trip” on Nov. 30. The outage is meant “to facilitate repairs to an unidentified steam leak on Unit 4 High Pressure Turbine,” according to an NRC event notification.

Meanwhile the Exelon (NYSE:EXC) Peach Bottom 2 facility in Pennsylvania, which has been in an outage lately, was listed at only 2%.
