Exelon Byron Nuclear Generating Station

Due to the recent detection of tritium at two other Exelon nuclear power plants in Illinois, Exelon inspected six vaults on the blow down line at the Bryon Generating Station in Ogle County.  Upon inspection, five of the vaults had standing water in them containing tritium.  Exelon contacted the federal Nuclear Regulatory Commission (NRC), Illinois Emergency Management Agency (IEMA) - Division of Nuclear Safety (DNS) and Illinois Environmental Protection Agency (Illinois EPA) in February 2006 to inform the two state agencies of their discovery.  Since that time, Exelon has been working with the Illinois EPA to investigate any tritium contamination in the groundwater.
