TRITIUM FOUND IN AN ONSITE SETTLING POND
"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.

EMERGENCY RESPONSE DATA SYSTEM AND SAFETY PARAMETER DISPLAY SYSTEM WILL BE UNAVAILABLE
"The BVPS Unit 2 Plant Computer System (PCS) will be taken out of service for approximately 5 weeks (8/25/06 to 9/26/06) to implement a planned modification. The current PCS is being replaced and a computer outage is required to allow for the installation of a new PCS. During this time period the Emergency Response Data System (ERDS) and Safety Parameter Display System (SPDS) will not be available at BVPS Unit 2. ERDS and SPDS parameters will be monitored by control board indications and a temporary computer system (with limited analog inputs). Compensatory actions have been developed, which include a revised emergency implementing procedure specifically addressing temporarily unavailable indications and having an extra Operations Communicator respond to the Control Room during any potential Unit 2 emergency to facilitate data transfer while ERDS/SPDS is out of service. Work on replacing the PCS and returning ERDS/SPDS will be ongoing continuously until complete.
"This is an 8-hour reportable event per 10 CFR50.72(b)(3)(xiii) Major Loss of Assessment Capability. The operation of BVPS Unit 1 and Unit 2 plant systems will not be affected due to this planned action. BVPS Unit 1 ERDS and SPDS will not be affected by these modifications.
"The NRC resident inspector has been notified."

"Work on replacing the PCS and returning ERD/SPDS remains continuously ongoing. However, minor hindrances have caused the scheduled completion of this function to now be October 1, 2006. Previously described compensatory actions remain in effect."
The licensee has notified the NRC resident inspector.
