Exelon touts reliability of Illinois nuclear plants

Amid all the talk of last week’s winter storm and the resultant grid debacle in Texas, Exelon on Monday issued a press release informing customers of just how reliably its Illinois nuclear power plants have been operating this winter.

The release might also be seen as a message to state lawmakers, who have yet to produce any legislation to aid the utility’s financially challenged nuclear facilities—of which two, Byron and Dresden, have been slated for retirement later this year, given the (so-far) absence of such legislation.

An Illinois lawmaker is hopeful that legislation is coming in the state that would benefit nuclear power plants. “I believe we’re going to have an incentive program that will be in partisan legislation,” said Andrew Chesney, Illinois state representative for the 89th District.

Chesney’s comment was included in a video story that aired on a TV news channel in Rockford, Ill. The news story focused on the negative financial impact that would result if the Byron nuclear power plant were to close in 2021.

Exelon Generation, operator of the largest nuclear reactor fleet in the United States, intends to downsize that fleet next year by retiring its Byron and Dresden plants. In an announcement released early this morning, Exelon said that the two-unit Byron, located near Byron, Ill., would be permanently closed in September 2021, followed in November by the two-unit Dresden, located in Morris, Ill.

Byron is licensed to operate for another 20 years; Dresden, a much older facility, is licensed for another decade.

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.

Nuclear Energy on the Edge

Yesterday, June 2, 2016, may have marked a watershed moment in the present day history of nuclear power plants in the United States, when two nuclear plants were selected by their owner for shutdown far in advance of their license expiration dates for economic reasons. The fast-moving pace of plants being shut down under similar economic circumstances (unbalanced energy markets that favor other forms of energy to the detriment of nuclear) signals a broken system that must be changed, now.
