Exelon Energy says it has finished upgrading equipment at a northern Illinois nuclear plant where a power failure caused a reactor to shut down two months ago.

The company says it has replaced electrical insulators in the switchyards that help move power to and from the reactors at the Byron Generating Station, which is located about 95 miles northwest of Chicago.

In January, an insulator in Unit 2 switchyard failed and interrupted power, causing the reactor to automatically shut down as a precaution.

Insulators are protective equipment that helps regulate the flow of electricity.

Exelon says Unit 1 was taken offline last week while upgrades were finished, and Unit 2 upgrades were finished over the weekend. Both units are back online at full power and generating electricity.
