Feb 7 (Reuters) - Exelon Corp's 1,136-megawatt
Unit 2 at the Byron nuclear power plant in Illinois has been
reconnected to the electrical grid and began producing
electricity by Tuesday afternoon, the company said.
The unit shut Jan. 30 when power to an insulator in the
facility's switchyard failed.
Repairs to the insulator were completed along with
maintenance and inspection tasks while the unit was offline,
Exelon said.
Byron 1 was operating at full power, according to the U.S.
Nuclear Regulatory Commission.
