【 摘 要 】

Technical information for the process of recovery of uranium from uranyl nitrate hexahydrate solutions that was developed as part of the Onsite Uranium Recycle (OSUR) project conducted at the Savannah River Site in the 1980's is summarized. The process involves an ion-exchange process to load the uranyl species from solution onto a cation resin that is subsequently dried using a microwave oven, and then calcined using a rotary calciner to produce U{sub 3}O{sub 8} powder. The information in this report was compiled to support critical decisions for new facilities and processes at the Y-12 National Security Complex. The information includes a detailed description of the process and process equipment that were developed for the OSUR project including the technical bases for the materials selection and process conditions. Additional process considerations and recommendations to for a new-design facility are also provided.
