| Abstract Scope |
Used nuclear fuel can be electrochemically reprocessed and the resulting materials can be immobilized in a dehalogenated salt iron phosphate glass form (DPFs). The creation of DPFs is difficult under realistic industry conditions, thus leading to challenges with processing and chemical durability. Current research focuses on dehalogenation of salt waste by mixing phosphoric acid with a simulated alkali chloride-based salt waste and heating between 300-600°C. These variations in temperature result in different levels of dechlorination. This product is then vitrified in an atmosphere of argon or air to achieve a stable product. Composition and properties of products were analyzed to determine processing parameters, chemical durabilities, and potential models of dechlorinated products. This poster explores the results of chemical durability tests performed on potential waste forms. The development of this project aims to achieve a higher Technology Readiness Level for phosphate-based dehalogenation. |
