Title	Agreement State Report - Elevated Airborne Uranium Levels Due to Equipment Malfunction
Event Description	The following report was received from the State of Tennessee Division of Radiological Health via e-mail: Tennessee's Division of Radiological Health was notified on Wednesday August 7, 2013 by the RSO from Aerojet Ordnance Tennessee, regarding the failure of a primary ventilation system. On August 5, 2013 at 10:00 AM, an employee at the Deflash Station observed smoke outside the operation booth while grinding burrs off radiography camera castings. A supervisor was notified and investigation showed the ventilation system was working, but the belt connecting the pump and fan was broken. Operations were suspended and personnel evacuated. The belt was replaced on the pumps and the ventilation system was up and operational by 10:30 AM. Event resulted in elevated airborne uranium concentrations. All personnel in the building submitted urinalysis. Workers at the Deflash station were wearing respiratory protection during time of event as part of standard procedures. Area air samplers along with environmental air samplers were pulled and analyzed; initial results identified no concerns of elevated concentrations. The State will follow-up and keep NRC informed of the status of our investigation. Tennessee Report Number:TN-13-134
