| ENS 54831 | 11 August 2020 15:30:00 | Agreement State | Fire Involving a Container Possessing Licensed Material | The following information was received from the state of Tennessee via email: An incident took place while processing a liner with water filters and Dry Active Waste (DAW) in it during filter shredding operation in the Filter Shredding area of the Radioactive Material Solutions (RMS) Building on site. The container contained mixed fission and activation products with Co-60 as a primary contaminant. A fire was observed in the steel Final Form Container (FFC) liner through the remote observation. The size of the fire was limited to the container itself. The FFC is a steel liner where the material accumulates and is contained in preparation for sealing for disposal. The filter processing room was accessed via a hatch and a crane was used to seal the FFC. The fire suppression system was activated to cool down the FFC liner. The Oak Ridge Fire Department responded to the site. Since the fire was contained to the FFC liner, the Oak Ridge Fire Department did not enter the building. The area radiation and air effluent stack monitors did not alarm. Samples from air samplers are being analyzed for airborne material. Staff that remained in the building will undergo a bioassay to assess for potential uptake. A follow-up report will be submitted within 30 days. TN Incident No.: TN-20-116 | ||
| ENS 54823 | 6 August 2020 19:30:00 | Agreement State | Agreement State Report - Radiography Camera Guide Tube Dented | The following was received from the Tennessee Division of Radiological Health via email: On August 6, 2020, World Testing radiographers were radiographing at Matrix Drilling in Lewisburg, Tennessee. They were radiographing pipes and one of the pipes (weighing approximately 1000 pounds) rolled onto the guide tube, denting it. They could not crank the source back in. They called the RSO ((Radiation Safety Officer)). The guide tube was curled and making it more difficult to get the source back into the camera. They pulled on the crank to straighten out the guide tube and with enough pressure they were able to get the source past the dent and back into the exposure device. They placed lead on the collimator for additional shielding while working with it. The camera was a Sentinel, Model 880D, Serial number D-1120. The (Ir-192) source serial number was 96522G, with an activity of 44Ci. The source was exposed for approximately 4 hours. All personnel involved were wearing dosimetry. There were no overexposures.

| ENS 54683 | 24 February 2020 04:00:00 | Agreement State | Agreement State Report - Lost Static Eliminators Containing Polonium-210 | The following information was obtained from the state of Tennessee via email: During a recent inventory at two different locations of Service King Collision Repair Centers, two static elimination devices were found to be missing. One location in Chattanooga, TN, lost the device during the transition of closing the repair center. Updated information will be included in a follow-up report. The information for the devices is below: Manufacturer Model Serial# Isotope Activity NRD, LLC P-2021 A2LV457 Po-210 10 mCi NRD, LLC P-2021 A2LU553 Po-210 10 mCi Tennessee Event Report ID No.: TN-20-076 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.

| ENS 54551 | 19 February 2020 05:00:00 | Agreement State | Agreement State Report - Loss of Devices Containing Am-241 | The following was received from the Tennessee Division of Radiological Health via email: During a recent inventory at Blues City Brewery, the environmental health and safety manager discovered that two devices (Industrial Dynamics CI-2GV/3) were missing. Devices had been out of use for 1 - 2 years. Actual activity (of the Am-241 sources) are unknown at this point. The activity will be reported during the follow-up report. Incident Report No.: TN-20-038 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.
