Exelon (NYSE:EXC) said its operators returned Byron Generating Station Unit 2 to full power on Thursday, May 19, after completing a planned refueling and maintenance outage that started April 18.
During the outage, workers performed more than 13,000 detailed inspections, maintenance activities and equipment upgrades, Exelon said in a May 20 news release.
In addition, about one-third of the nuclear fuel was replaced during the outage.
More than 1,200 temporary skilled workers from local union halls and technical experts from other Exelon Generation facilities supported Byron Station’s employees during the refueling outage, Exelon said.
Byron Generating Station is in Ogle County, Ill., about 25 miles southwest of Rockford. Byron has two pressurized water reactors (PWRs) that were commissioned in the 1980s. Each unit can generate more than 1,100 MW.
Exelon recently received renewed licenses for the two reactors that authorize Unit 1 to operate through Oct. 31, 2044, and Unit 2 through Nov. 6, 2046.
