AGREEMENT STATE REPORT - THEFT OF AN X-RAY FLUORESCENCE ANALYZER
The following report was received from the Radioactive Materials Section of the Illinois Emergency Management Agency:
"[Arcos Environmental] a General Licensee, called the agency [Illinois Emergency Management Agency (IEMA)] to advise that a x-ray fluorescence analyzer [containing a 5 millicurie Cd-109 source] for measuring lead content of paint was stolen from a locked vehicle while at a temporary jobsite. The device along with several other items was removed from the car's trunk while it was parked at 6020 S. Langley Ave., Chicago, IL. At the time of the theft, the responsible user was in a building performing other duties. The theft was promptly reported to the Chicago Police Department. The general licensee is considering a news paper ad to encourage return of the device to its Tinley Park offices.
"Use of the device requires a 'pass code' to activate the device's features and allow exposure of the radioactive source by the opening of an internal shutter. The pass code is maintained separate from the device. In addition, 6 years after the source has been installed, the device will no longer operate and a display message directs that the device be returned to the manufacturer. This device was initially sourced in Sept of 2007.
"The maximum surface dose rate from the device is less than 100 microR/h when the shutter is closed. Based on the SSDR safety evaluation the maximum exposure rate, should the safety and security features be defeated and the shutter opened, would be 3 milliR/h. As a result, the potential radiation exposure to the thief or any member of the public is projected to be extremely low.
"The general licensee has been advised of the requirement to file a written report within 30 days of the theft. The agency [IEMA] does not intend to conduct an on-site investigation unless additional information or circumstances change which warrant a visit."
Illinois Report Number: IL11086
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.

OVERFLOW OF CONDENSER CIRCULATING WATER
"At 0023 on 07/13/2011, a notification to an outside state agency, Tennessee Department of Environment and Conservation (TDEC), was made due to an overflow of Condenser Circulating Water from the northwest corner of the diffuser pond through a heavily vegetated area into a slough adjacent to the Sequoyah Training Center. Condenser Circulating Water is also discharging to the river via storm water outfall 14 near the cooling towers as well as the normal diffuser pond discharge at outfall 101.
"At approximately 1545 on 07/12/2011, one of the two diffuser gates at Sequoyah failed and shut off the west diffuser pipe. The other diffuser remained open throughout the event. Plant personnel made several attempts to raise the diffuser gate utilizing divers and cranes. When it was determined the crane could not lift the diffuser gate, both units reduced power to 85% and one (1) Condenser Circulating Water pump for each unit, two (2) pumps total, were removed from service. Diffuser pond level is currently lowering."
The NRC Resident Inspector has been informed.
