Beginning in 1993, IES began working in concert with the US Department of Energy (DOE) to safely manage both radioactive gases and contaminated cylinders. This effort began with converting radioactive gas to a more easily managed solid-phase material and evolved into providing gas cylinder management services throughout the DOE National Laboratory complex. In 1997, IES installed a comprehensive cylinder management system known as the "Transportable Compressed Gas Recontainerization Skid" at the K-25 facility in Oak Ridge, Tennessee. During the next five years, more than 2,000 radioactively contaminated cylinders were processed at this facility. Materials including uranium hexafluoride, krypton-85, and isotopic acetylene have all been successfully managed at DOE facilities across the United States.
IES establishes waste processing facility in a Class II Nuclear Facility
IES is the first company to establish a waste processing facility inside a Class II Nuclear Facility. Since late 2009, IES has been operating a Uranium Hexafluoride (UF6) processing facility at the U.S. Department of Energy Portsmouth Gaseous Diffusion Plant on an “as needed basis”. This transportable system is located within a building designated as a Class II Nuclear Facility. All equipment and processes in such locations are subjected to extremely high quality and control standards. In addition, all operations personnel undergo intensive training and continual evaluation.
The IES facility is designed to reduce UF6 into a waste material suitable for landfill disposal. The facility neutralizes the target material’s fluorinated component and causes the radioactive component to precipitate into a specialized reagent. Upon completion of processing, cement is added to the waste liquid to produce a solidified mass that is then ready for landfilling.
IES designed, built, and tested the computer-controlled processing system. A system control computer remotely monitors temperatures, pressures, and weights, processing the input to automatically control most operational functions. System operators monitor all process functions at a control console and perform tasks that are not computer controlled.
IES has processed over 500 cylinders in the facility to date.
