SOURCE CONTACTS: Steve Gurr, Environmental Engineer 801-649-2043, sdgurr@energysolutions.com Nick Clarke, Licensing and Compliance Specialist 801-649-2157, nwclarke@energysolutions.com OPERATING STATUS: Normal operations. PROCESS DESCRIPTION: EnergySolutions is a low-level radioactive and mixed waste treatment, storage, and disposal operation. Radioactive or mixed waste from various locations is transported to the source location via over the road trucks or rail. Rail shipments arriving at the source location are tested for moisture content at a rate of 20% with at least one test being performed each day conveyances are unloaded. Water is added to any shipment with moisture content less than 7%. These shipments are then unloaded via a railcar rollover or by using a hydraulic excavator. The waste is then loaded into large haul trucks and transported to the source location's disposal embankments for permanent burial. Low level waste placed into the embankment is compacted using large sheep foot compactors to minimize future settlement. Mixed waste is placed, compacted using any means necessary, and tested using nuclear density gauge technology to ensure minimal settling will occur. All over-the-road or rail conveyances are decontaminated to meet specific DOT requirements prior to being released back into service. The source is permitted to treat and dispose mixed waste (radioactive waste with a hazardous 0 . ) $ . ) - " 2 component). Mixed waste is treated to meet land disposal restrictions using a variety of methods. These methods include stabilization, macro encapsulation (encasing the waste in a proprietary concrete mixture), and thermal desorption (indirect heating of the waste to drive off organics). The thermal desorption unit is used to treat solid and slurry wastes contaminated with both radioactive and hazardous material. It employs a treatment system where the gases are filtered, condensed, and discharged through the carbon adsorption system. The waste stream is then routed through a primary filter and then to HEPA filters before exiting to the air.
