AGREEMENT STATE REPORT - DAMAGED MOISTURE DENSITY GAUGE

A Troxler Moisture Density gauge was in use when it was run over by a truck. The operator attempted to wave off the truck. The rod was stuck in the extended position. The operator secured an area 25 feet around the damaged gauge. The company's RSO responded, placed a pipe sleeve around the rod, and put the rod in a bucket of sand. A staff member from the Florida Bureau of Radiation observed the recovery. The gauge was transported and then stored in the company's storage facility. The company will notify Troxler.

UNPLANNED, INVALID ACTUATION OF EMERGENCY DIESEL GENERATOR

"This 60-day telephone notification is being made under reporting requirements specified by 10 CFR 50.73(a)(2)(iv)(A) to describe an invalid actuation of any of the equipment specified in paragraph 50.73(a)(2)(iv)(B). In this case, the equipment actuated was emergency diesel generator (EDG) A. This EDG is common equipment for Units 1 and 2.

"On January 13, 2006, troubleshooting was being conducted by maintenance personnel to determine the cause of observed alarm malfunctions on the EDG A local annunciator panel. Browns Ferry Unit 1 was shutdown and defueled and Unit 2 was operating at 100% thermal power. During this troubleshooting activity, at 1157 hours CST, EDG A was inadvertently started. The exact cause of the start could not be conclusively determined.
EDG A properly started and ran in response to the invalid start signal. No loss of normal plant electrical power occurred, and the EDG did not connect to its associated shutdown board. The EDG was allowed to run for approximately one hour, and then it was shut down in accordance with plant operating procedures.

"Since no actual plant condition existed which required the EDG to start, and since the start occurred inadvertently, most likely as a result of a human error during the electrical circuit troubleshooting effort, this EDG start is classified as invalid.

"There were no safety consequences or impacts on the health and safety of the public. The event was entered into TVA's corrective action program for evaluation and resolution. [Reference BFN corrective action document PER 96291]."


The licensee notified the NRC Resident Inspector.

OFFSITE NOTIFICATION DUE TO LUBE OIL SPILL

"On 03/06/06 at 10:40 [EST] a plant operator was dispatched to investigate an unexpected Annunciator D-43, 'TURBINE LUBE OIL RESERVIOR LEVEL HIGH/LOW'. He reported the alarm was a valid low reservoir level [for the main turbine]. A contractor painter had inadvertently bumped open a drain valve on the Kaydon turbine oil filter system. The valve has been closed.

"The spilled oil was contained within the Unit 1 Turbine Lube Oil Secondary Containment Structure. The volume of spilled oil has been calculated to be approximately 200 gallons. The Florida Department of Environmental Protection. (DEP) was notified on 3/6/06 at 12:20 EST in accordance with plant procedures for oil spills greater than 25 gallons on a pervious surface. No equipment damage was incurred due to the loss of reservoir level. Actions to retrieve the spilled oil are in progress.

"This non-emergency notification is being made pursuant to 10 CFR 50.72(b)(2)(xi.) due to the notification of the Offsite Agency - DEP,"


The licensee notified the NRC Resident Inspector.
