POTENTIAL VIOLATION OF LICENSE INVOLVING AN INADVERTENT DISPOSAL OF RADIOACTIVE MATERIAL
On Monday 8/20/07, a package containing a small quantity of natural uranium, was inadvertently discarded and taken to the Bridgeton Landfill. The material was shipped as an Excepted Package - Limited Quantity from General Engineering Laboratory which is located in South Carolina to TestAmerica. The package was received, opened and set aside. On Monday, workers inadvertently disposed of the package as trash. The total activity of the material was .265 microcuries (natural uranium with a specific activity of 34 picocuries/gm). The licensee does not believe that a search of the landfill would locate the material due to the shredding and mulching process and the extremely small quantity involved. An accident investigation is in progress which will identify appropriate corrective actions.
The licensee will notify the State of Missouri Department of Natural Resources.
THIS MATERIAL EVENT CONTAINS A "LESS THAN CAT 3" LEVEL OF RADIOACTIVE MATERIAL
Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks.
This source is not amongst those sources or devices identified by the IAEA Code of Conduct for the Safety & Security of Radioactive Sources to be of concern from a radiological standpoint. Therefore is it being categorized as a less than Category 3 source

ELECTRICAL BREAKER B4305 UNABLE TO FUNCTION
"During panel walk downs in the Main Control Room, an Operator discovered no light indication for V-AC-4, B RHR ROOM AIR COOLING UNIT. Operator was dispatched to Breaker B4305 and 'B' RHR room to determine cause of loss of indicating light. The Operator determined that breaker B4305 (V-AC-4, 'B' RHR ROOM AIR COOLING UNIT 480V SUPPLY) was unable to function. Division II RHR pumps, Division II CS pump, and associated low pressure injection systems were declared inoperable. Tech Spec Actions 3.5.1.A, 3.5.1.B, and 3.5.1.M were entered resulting in entry into LCO 3.0.3 at 1053 on August 20, 2007. At 1151 on August 20, 2007 power reduction was commenced using normal shutdown procedures.
"Site Electricians determined that a line fuse had blown. The fan motor was meggared and all three line fuses were replaced. At 1230 on August 20, 2007, V-AC-4 was tested and returned to service. Division II RHR pumps, Division II CS pump and associated low pressure injection systems were declared operable. LCO 3.0.3 and T.S. Actions 3.5.1.A, 3.5.1.B, and 3.5.1.M were exited. Power reduction was terminated at 98%."
At the completion of the call the power level had returned to 100%.
The licensee notified the NRC Resident Inspector.

INOPERABLE HOUSE SERVICE TRANSFORMERS
"This report is made in compliance with Tech spec 2.7, 4 hour NRC notification of inoperable house service transformers. The 161 Kv electrical supply to both house service transformers T1A-3 and T1A-4 was lost at 21:03 EDT. Fast transfer to 22 Kv was successful. AOP-31, 161 Kv Grid Malfunctions, abnormal operating procedure was entered. Technical Specification 2.7 (2) c, 72 hour LCO was entered.
"Background: The site was in a tornado warning between 20:30 and 21:00 EDT. Wind speeds were observed in excess of 60 mph by the site weather tower. One of the two switchyard breakers 3451-5 on the 345 Kv system opened at 20:50 EDT. The 345 Kv output breaker 3451-4 remained closed."
The EDG are in standby and ready for service if required.
The licensee notified the NRC Resident Inspector.
* * * UPDATE ON 08/21/07 AT 0400 EDT FROM K. BOSTON TO MACKINNON * * *
The 161Kv electrical supply has been returned to service and Tech Spec 2.7(2)c has been exited at 0029 EDT on 08/21/07. Breaker 3451-5 remains open. System walk downs have to be completed before breaker 3451-5 can be closed. R4DO (J. Clark) notified.
The NRC Resident Inspector is presently in the control room.
