10 CFR Section: SCOTT SHAEFFER (R2DO) 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 I 1001 Power Operation Event Text OFFSITE NOTIFICATION DUE TO DISCOVERY OF TRITIUM IN WATER LEAKAGE ONSITE "At 8:30 a.m. on January 10, 2010, an operator on regular rounds discovered the underground Waste Neutralization Basin Flash Mixer Return Pipe had developed a leak. The eight-inch fiberglass pipe carries secondary plant and water treatment building waste water for chemical processing.
Approximately 1,000 gallons of water containing a low level of tritium (5,590 picocuries per liter) leaked into the surrounding soil. The EPA Drinking Water Standard is 20,000 picocuries per liter.
"Once the leak was discovered, the system was secured and the leak was isolated. Crews are repairing the pipe. The spill has been contained within the plant backfill and is unlikely to migrate off-site or reach the water table. The affected area is located within the plant's site boundary, approximately 15 feet west of the Water Treatment Building, and involves roughly 100 cubic feet of soil. Once repaired, the system will be tested and returned to service.
"Immediate remedial actions involving the affected area include: pumping the water from the saturated ground back into the waste neutralization basin, removal of the tritiated soil and sampling soil in the area for tritium analysis.
"The health and safety of the public are not affected by this event, based on the location of the leak and the low tritium levels.
