10 CFR Section: JOHN WHITE (RIDO) 50.72(b)(2)(xi) - OFFSITE NOTIFICATION SCRAM Initial Current Unit Code RX CRIT PWR Initial RX Mode PWR Current RX Mode 1 N Y 100 Power Operation 1001 Power Qperation Event Text OFFSITE NOTIFICATION DUE TO A WATER LEAK CONTAINING TRITIUM "Oyster Creek Nuclear Generating Station notified the New Jersey Department of Environmental Protection of a leak of water containing tritium from an underground condensate transfer pipe at the turbine building penetration of less than 20 gpm and concentration of approximately 10 million picocuries/milliliter. N.

"The leaking water is being pumped to storage drums and a plan is being developed to replace the six-inch condensate transfer piping which penetrates the turbine building inside a 42 Inch long sixteen inch diameter penetration sleeve. Previously, water was observed coming from the sleeve into the turbine building where it was draining to a sump. The leak coming out of the turbine building was uncovered during excavation to determine if the condensate was leaking to the soil."

The licensee notified the NRC Resident Inspector.

The licensee corrected the reported concentration to 10 million picocuries/liter.

Additionally, after closer examination the leak rate was determined to be approximately 5 GPM vice the initially reported less than 20 GPM.

The licensee will be issuing a press release.
