United States Project Notice - Metal-Halide Perovskites As Innovative And Cost-Effective Fluoride Salt Waste Forms

Project Notice

PNR 62184
Project Name Metal-Halide Perovskites as Innovative and Cost-Effective Fluoride Salt Waste Forms
Project Detail Rensselaer Polytechnic Institute (RPI) will explore using inorganic metal halide perovskites (MHPs) as advanced salt waste forms to immobilize fluoride-based salt wastes from advanced reactors. The RPI team will demonstrate low-temperature wet-chemistry processes to effectively separate fluoride salt wastes at temperatures lower than 200oC and reduce the waste volume of alkali and alkaline earth fluoride salt waste by 90 l.%. The second technical goal is to separate useful lithium fluoride from the fluoride salt wastes with a yield over 95%. The scalability of a low-temperature wet-chemistry process in synthesizing large quantity MHPs up to 50 grams at the lab scale will also be targeted. Effective management of fluoride salt wastes are critical for the sustainable development of advanced nuclear fuel cycles and future nuclear technologies. The recycling of valuable lithium from salt waste is also significant to recover the indispensable and critical resource in large demands for advanced reactors and renewable energy applications. Potential Impact: By identifying and addressing challenges at the back end of the fuel cycle before the deployment of future AR technologies, ONWARDS will:
