BYRON, Ill. - Operators at Byron Generating Station terminated the Unusual Event on Unit 1 at 9 p.m. Wednesday, following the restoration of the redundant power line from outside of the nuclear facility to the unit. Both Byron reactors continued to safely supply electricity to customers throughout the Unusual Event.
A failed insulator in the facility's switchyard caused the loss of power on Tuesday, Feb. 28. Site technical personnel have been working since late January on a replacement plan for all of these insulators in the switchyard.
"We are working on a plan to inspect all the switchyard insulators and replace them as necessary," said Byron Station Site Vice President Tim Tulon.
The Unusual Event is the lowest of the four emergency classifications as established by the NRC.
Byron Generating Station is in Ogle County, Ill., about 25 miles southwest of Rockford.
