| Title | Tritium Found in an Onsite Settling Pond |
| Event Description | This notification is being made pursuant to 10 CFR 50.72(b)(2)(xi) due to notification of other government agencies at 15:30 on 8-25-06.
Florida Power & Light Company (PPL) has identified a small amount of tritium in a settling pond at its St. Lucie Nuclear Plant Site. The level of tritium detected in the settling pond, 3.0 E-6 microCuries per milliliter (uCi/ml), is well below the Environmental Protection Agency's (EPA) drinking water standards of 2.0 E-5 uCi/ml and is less than two per cent of the Nuclear Regulatory Commission's (NRC) safe standards for tritium that apply to water in an unrestricted area. The source of the tritium is under investigation. The most likely source was from a leaking drain valve off a recirculating line associated with the Refueling Water Storage Tank. The leak has been stopped. This discovery presents no health or safety risk to employees or the public. The St. Lucie Plant does not have drinking water wells on site and the plant does not impact drinking water off site. The settling pond is a part of the normal drainage process at St. Lucie. Any water that is released from the settling pond is sampled for radioactivity and the results of any findings are included in a Radioactive Effluent Release Report that is filed annually with the NRC. Monitoring of the settling pond is conducted on a monthly basis. The previous measurements of the pond water on July 20, 2006 indicated that there was no tritium present. Notification to the State of Florida and St. Lucie and Martin county agencies has been reported in accordance with the Nuclear Energy Institute's voluntary reporting initiative. The licensee notified the NRC Resident Inspector. |
