Nuclear update: Loss of 2 units pulls total US output lower

The loss of several nuclear reactors worked to pull total U.S. nuclear power plant availability down to 85.96% as of early Oct. 16, from 86.72% on Oct. 13 but still above the 80.35% recorded on the same day a year earlier.

Southern Co.'s Joseph M. Farley plant in Alabama and Xcel Energy Inc.'s Prairie Island 2 in Minnesota were both idled for what sources indicate is planned refueling work.

Additionally, Duke Energy Corp.'s Oconee 2 in South Carolina was reported at 91% as of early Oct. 16, down from 96% on Oct. 13, and Exelon Corp.'s Peach Bottom 3 reactor in Pennsylvania was eyed at 79% as of early Oct. 16, down from 82% on Oct. 13. Both units are coasting down to planned refueling outages, according to private sources.

Conversely, Duke's Shearon Harris plant in North Carolina saw output return to 100% as of early Oct. 16 after it was cut to 27% as of Oct. 13, down from full capacity the day prior.
