Steam Reforming Application for Treatment of DOE Sodium-Bearing Tank Wastes at Idaho National Laboratory for Idaho Cleanup Project
The patented THOR~? steam reforming waste treatment technology has been selected by the U.S. Department of Energy (DOE) as the technology of choice for treatment of about one million gallons of sodium-bearing waste (SBW) at the Idaho National Laboratory (INL) Site. SBW is an acidic waste created primarily from cleanup of the fuel reprocessing equipment at the Idaho Nuclear Technology and Engineering Center (INTEC) at the INL. SBW contains high concentrations of nitric acid and alkali and aluminum nitrates with minor amounts of many inorganic compounds including radionuclides, mainly cesium. The steam reforming process will convert the SBW into dry, solid, carbonate and aluminate minerals supporting a preferred path for disposal as remote handled transuranic (RH-TRU) waste at the Waste Isolation Pilot Project (WIPP). The Idaho Cleanup Project (ICP) will design, build, and operate an Integrated Waste Treatment Unit (IWTU) that will comprise an integrated THOR~? process system that will utilize dual fluidized bed steam reformers (FBSR) for treatment of the SBW. The IWTU is being constructed at INTEC, immediately east of the New Waste Calcine Facility (NWCF). Detailed design of the IWTU has been completed and DOE has approved the CD-3 detailed design. The State of Idaho has approved the RCRA and construction air permits. Construction of the IWTU started in April 2007 with civil and foundation work. This paper provides a project and process overview of the IWTU and discusses the design and construction status. IWTU equipment and facility designs and bases will be presented.
