This notification is being made pursuant t … This notification is being made pursuant to 10 CFR 50.72(b)(2)(xi) due to the notification of the Illinois Emergency Management Agency (IEMA) and the Illinois Environmental Protection Agency (IEPA) of an unpermitted release of radionuclides at LaSalle County Station. This notification was made at 0903 on July 1, 2010. A news release is planned, which is also reportable under 10 CFR 50.72(b)(2)(xi), this notification satisfies the additional reporting requirement.</br>On June 30, 2010, a small leak of radioactive water from the Unit 1 Cycled Condensate Storage (CY) Tank to the ground was confirmed by analysis of water from an adjacent groundwater test well. The IEMA / IEPA require notification when a release to soil, groundwater or surface water results in tritium concentrations of 200 pCi/I or more outside the licensee controlled area, or contains tritium at quantities of 0.002 Curies or more on-site. Positive groundwater test well sample result was obtained at 1800 on June 30, 2010 from the well adjacent to the Cycled Condensate Storage Tank. Samples found a tritium concentration of 715,000 pCi/I, with a confirmatory sample result of 696,000 pCi/I. The concentration of tritium in the sampled well makes it likely that the release is in excess of 0.002 Curies.</br>Based on sampling data obtained to date, the tritium in the groundwater is confined to Exelon property and poses no threat to public safety. The Station continues to track this issue by monitoring groundwater test wells. Plans to repair the leak in the Unit 1 CY tank are in progress.</br>The licensee has notified the NRC Resident Inspector and State authorities. The licensee also plans to notify authorities and will be issuing a press release.ities and will be issuing a press release. +
