SiteTitle | • | Exelon Byron Nuclear Generating Station On-going Tritium Investigation | [X] |
| | 1: | | Title: | | | | | Volume/Number: | 2006 April | | | | Issuing Agency: | | | | | Description: | Exelon Corporation operates the Byron Nuclear Generating Station in Ogle County. On February 13, 2006, the Illinois Emergency Management Agency (IEMA) Division of Nuclear Safety notified the Illinois Environmental Protection Agency (Illinois EPA or Agency) that Exelon had inspected six vacuum breaker relief valves along the three-mile long blowdown line which runs west from the station to the Rock River. The blowdown line carries process water and wastewater from the plant and occasionally tritium. Five of the vaults had standing water in them. The vacuum breaker vaults, which are part of the discharge system, have weep holes on the bottom that threatened the release to groundwater of the standing water in the vaults. No discharges down the line occurred from late January to April 20, when releases down the discharge line resumed. The station is installing leak detection devices at each vault along the line to give immediate notification should a leak occur. In the interim, visual inspections will occur at each vacuum breaker location during each planned release to ensure no further leakage occurs. The printable map referenced in the fact sheet will be included in a separate pdf attachment. | | | | Date Created: | 05 14 2012 | | | | Agency ID: | Fact Sheet #1 | | | | ISL ID: | 000000042217 Original UID: 21735 FIRST WORD: Exelon | |
