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.
- UPDATE PROVIDED BY CALVIN TAYLOR TO JASON KOZAL AT 0907 ON 08/26/09 ***
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.
