Illinois plants set outage performance marks

Four of six Illinois nuclear power plants—Braidwood, Byron, LaSalle, and Quad Cities—set operational records while conducting spring refueling outages amid the COVID-19 pandemic.

Performance records include the shortest refueling outage (18 days) at LaSalle; the shortest refueling outage at Quad Cities (16 days), as well as the completion of the site’s longest continuous run (722 days); and the completion at both Braidwood and Byron of their sixth consecutive continuous cycle of operations, also known as a “breaker-to-breaker” run, according to a May 7 press release from Exelon Generation. Exelon’s average outage duration in Illinois this spring was 17 days, a full two weeks shorter than the national average, the release stated.
