| ENS 48577 | 11 December 2012 09:05:00 | The following information was obtained from the State of Tennessee via email: On 12/10/12 at 4:30 pm EST, (the) RSO (at) Energy Solutions-Bear Creek called (the State of Tennessee) to report that last Friday, 12/7/12, a drum of DU shavings had been placed in Area 9 of the old ATG building and covered w/mineral oil. When (workers) came to work on 12/10/12, they noticed that the poly drum was completely gone, the shavings were on the floor, oil was on the floor and some of the shavings looked like ash. The poly drum had burned up and the drum/shavings and oil/ash/shavings were now on the concrete floor. There was no stack release. The stack samples were pulled and indicated less than MDA: < E-14 for U-238 and <E-15 for U- 235. Workers were not allowed to enter the area/bldg. A Hi-Volume sample was pulled with no detectable findings. Smear samples were taken with a maximum reading of 11,000 dpm. The pre-filter will be removed and counted. (Workers) are in the process of checking the temperature from a distance using a remote thermometer in order to determine if they can transfer the shavings from the floor into another oil filled container. There was no release into any drains, there was no release into the air, and there were no personnel involved/no personnel contamination. A written report is being prepared and will be sent to the Division (Tennessee Division of Radiological Health). Tennessee Report No.: TN-12-305
The following report was received via e-mail: This is a request for event notification (EN #48577) to be retracted. The State of Tennessee Division of Radiological Health (DRH) investigation has determined, based on the information Energy Solutions (ES) supplied and the amount of DU (Depleted Uranium) lost, incident TN-12-305 did not meet the reporting requirements for the greater than five times ALI criteria. Therefore, Event Notification Report #48577 is being retracted. It was concluded that 126 grams of DU, or less than 37 MBq (1 mCi) of activity, is unaccounted for as a result of the oxidation incident. Energy Solutions stated that the work area sample results were 0.46 uBq/ml (1.25E-11 uCi/ml) alpha and 1.85 uBq/ml (5E-11 uCi/ml) beta with field instrument checks. Results were also less than MDA alpha and 0.2 (5.46E-12) beta with laboratory equipment checks (gamma spec). Correspondingly, the field check revealed 1.79 DAC based on 0.26 uBq/ml (7E-12 uCi/ml) DAC for Pu-239. Energy Solutions concluded that an inappropriate storage vessel was used. Corrective actions included operator training, procedural revisions, and external review by proper ES personnel. Notified R1DO (Dwyer) and FSME Events Resource. |
| ENS 50111 | 12 May 2014 17:10:00 | The Tennessee Division of Radiological Health (DRH) performed an inspection of Blues City Brewery (BCB) on 9/21/2011. The facility was previously owned by Coors Brewing Company through 9/1/2006. During the inspection, it was discovered that a 3.7 GBq (100 mCi) Am-241 source (Industrial Dynamics Company - IDC model 06110-1, serial #5533) was missing. The source had originally been contained inside a level gauge (IDC model FT -100, serial #90205). According to IDC records, IDC had removed the source from the gauge on 9/29/1999, wipe tested the source, packaged it for shipment, and left the package in the possession of the Coors Brewing Company's RSO. The IDC RSO stated that they had no further record regarding the source. BCB conducted a thorough search of their facility for the source without success. DRH contacted the former Coors Brewing Company's RSO, but he did not have any additional information regarding this source. On 10/25/2012, DRH received a quarterly report (7/1/2012 to 9/30/2012) from IDC that stated they recovered the source. Tennessee Event TN-12-126.
