NRC Announces Hearing Opportunity for License Renewal of Exelon's Byron and Braidwood Nuclear Stations

LCG, July 25, 2013--The Nuclear Regulatory Commission (NRC) announced yesterday the opportunity to request an adjudicatory hearing on Exelon Generation Company's application to renew the operating licenses of the Byron and Braidwood nuclear power plants, which are located in Illinois. If the licenses are extended, nearly 2,700 MW of non-carbon emitting generating capacity will survive for another 20 years.

Exelon filed the application on May 29, and the NRC staff has determined the application is sufficiently complete to allow the staff to formally docket the application and commence its technical and environmental reviews.

Exelon filed the application to renew and extend the operating licenses for an additional 20 years of operation. The current operating licenses for Braidwood expire on October 17, 2026, for Unit 1 and December 18, 2027, for Unit 2; the licenses for Byron expire October 31, 2024, for Unit 1 and November 6, 2026, for Unit 2.

The Braidwood Nuclear Station, with a capacity of 2,360 MW, is Exelon's newest nuclear power plant and is located about 60 miles southwest of Chicago. The Byron Nuclear Station is located about 110 miles west of Chicago and has a net generating capacity of 2,336 MW.

Both stations include two pressurized-water reactors.

Exelon submitted a single application to cover both plants due to the similarities in the systems, structures and components of each that are analyzed in a license renewal review.

The NRC stated that requests for a hearing on the application must be filed by September 23.
