Byron Station Declares Unusual Event, Both Units Operating

BYRON, Ill. - Operators at Byron Generating Station declared an Unusual Event for Unit 1 at 5:31 p.m. CT, when power coming in from outside of the nuclear facility was interrupted. Both units are operating at 100 percent power, and the facility is in a safe condition.

The facility responded as designed with one of the station's many redundant power sources providing electricity for Unit 1.

The Nuclear Regulatory Commission (NRC), the federal oversight organization, requires a nuclear facility to designate an Unusual Event in events such as this.

A failed insulator in the station's switchyard is believed to be the cause for the loss of power. Technical crews will be in the switchyard this evening and Wednesday to replace the insulator.

Exelon Nuclear has notified all appropriate local, state and federal officials of the Unusual Event.

An Unusual Event is the lowest of four emergency classifications established by the U.S. Nuclear Regulatory Commission.

Byron Generating Station is in Ogle County, Ill., about 25 miles southwest of Rockford.
