STOLEN TROXLER GAUGE

"On Wednesday, December 17, 2008 a Troxler moisture density gauge, Model 3430 (S/N 37875 with 8mCi of Cs-137 S/N 77-5152; and 40mCi of AmBe-241 S/N 78-2656) was stolen from the bed of a company pick-up truck along with some other field equipment. The transport case was chained as required by company procedures, but the entire case with gauge was noted missing when the technician briefly left the truck unattended. The chain had been cut and the theft was immediately reported to the Dallas Police Department. The area will be canvassed and dumpsters checked to see if the device had been inadvertently discarded. A reward will be posted through a notice that will be distributed to local authorities."

TX Case Number I-8591.

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.

AGREEMENT STATE REPORT - MISSING NUCLEAR GAUGE

"The gauge was discovered missing after Agency [Texas Department of Health] attempts to collect fees. Gauge registrant had provided self evaluation reports indicating they possessed the gauge and, after being contacted, admitted it was missing. The company had 2 gauges. The second was returned to Thermo Scientific. The missing gauge is reported to contain 1 curie of Cs-137. However, the manufacturer's information indicates it held 2 curies. A site investigation will be performed 12/09/08. A site investigation will be performed 12/09/08.

"The licensee continues to dispute inappropriate disposition of the gauge/source but cannot produce documentation to support the statement. The gauge is most likely fixed on a dredge in Florida but until definitive documentation is produced to support or show the whereabouts of the source, the Agency must formerly declare the source missing. A draft Notice of Violation is being developed to call the company in for enforcement.

"The source information follows:

"Manufacturer: Thermo
"MeasureTech (Now Thermo Fisher Scientific), Model: 5203,
"Serial Number: B996, Isotope: Cs-137, Activity: 2 Ci,
"Source serial number: GK3804"

AGREEMENT STATE REPORT - NON-NUCLEAR WORKERS RECEIVE RADIATION OVEREXPOSURE

The following report was received via e-mail:

"On December 18, 2008, the licensee confirmed that four of their workers, who are not considered to be radiation workers, exceeded the annual exposure limit for members of the general public of 100 millirem due to the detachment of the source from the operating rod. The dose to these individuals are: employee 1 - 280 mrem, employee 2 - 2962 mrem, employee 3 - 960 mrem, employee 4 - 78 mrem, employee 5 - 166 mrem.

"The licensee will send supporting information to the Agency [Texas Department of Health] within the next few days."

DEFECTIVE OPTICAL ISOLATORS

"Duke Energy Carolinas, LLC (Duke) herein makes the following notification under 10CFR21.21(d)(3)(i) of defective digital optical isolators. The isolators are Commercial Grade Items dedicated by Duke. Failure analysis conducted by the manufacturer determined that a manufacturing defect with the isolator capacitor will cause the output voltage to drop when the isolator is not energized and there is a very light load on the output. The subject digital optical isolators are Model 175C180, manufactured by E-max Instruments (also known as Electro-Max) 13 Inverness Way, South Englewood, CO 80112. These digital optical isolators could be utilized in a variety of applications at Duke's McGuire and Catawba nuclear stations. There are no known applications for these digital optical isolators at Oconee.

"Initial Safety Significance: None. Defective digital optical isolators were never installed. Duke protocols require the conduct of a pre-installation bench test and a post installation test to assure these isolators perform satisfactorily in service. E-max Instruments has issued a Model 175C180 recall for all uninstalled isolators. Duke has returned all uninstalled digital optical isolators to the supplier. Duke is the only known nuclear utility purchasing E-max Instruments Model 175C180 digital optical isolators.

"The McGuire and Catawba Senior NRC Resident Inspectors were notified of this Part 21 notification on Dec 18, 2008."

* * * UPDATE FROM JIM EFFINGER TO PETE SNYDER AT 0810 0N 12/22/08 * * *

McGuire Nuclear Station clarified that one of the defective digital optical isolators mentioned in the second paragraph above was scrapped, one was sent to Westinghouse Electric of Pittsburgh for a compatibility test program and the rest of the defective digital optical isolators were returned to the supplier. Even if Westinghouse returns the digital optical isolator given to them, it will not be installed.

The licensee will notify the NRC Resident Inspector. Notified R2DO (Henson), NRR EO (Mike Cheok), and Part 21 Group.
