VP.IsIVi I1MIIIV L1 V~l. -I I MLU1I II IV4UU0L.VVP.U I --.>9 Region Ill: Braidwood; On November 30, 2005, the licensee informed the NRC Resident Inspectors of higher than expected tritium levels (-58,000 picoCuries per liter) measured in on-site monitoring wells at the northern edge of the owner controlled area. The licensee attributed the higher levels of tritium to historical vacuum breaker valve leakage in the circulating water blowdown line to the Kankakee River that occurred in 1998 and 2000. The licensee uses the blowdown line to perform liquid effluent releases to the river.As of December 6, 2005, the licensee has detected measurable levels of tritium in offsite groundwater.

Elevated levels were detected in one offsite monitoring well in a vacant development (as high as 33,700 picoCuries per liter). One nearby residential well was found to have detectable tritium (1,150 picoCuries per liter). The licensee is continuing to sample and to develop plans for remediation.
