Evaluation of corrosion coupons exposed to molten-chloride electrorefiner salts long term
Corrosion mitigation has long been considered a challenge in long-term service of both pyrochemical reprocessing and molten salt reactor applications. Corrosion coupons consisting of 2.25Cr 1Mo ASME SA387 Grade 22 Class 2 steel, were installed in a uranium electrorefiner containing molten chloride salt at 500°C. This electrorefiner went into service at Idaho National Laboratory in […]
Separation of fission products from high-level waste salt systems by partial crystallization: CsCl-NaCl-LiCl-KCl study
Pyroprocessing refers to a series of high-temperature molten-salt processes used to manage and recycle nuclear materials to reduce the waste volume and hazardous environmental impact of the final waste product. In these processes, fission products with high halide affinity, including cesium (Cs-137) with a half-life of 30 years that decays to barium (Ba-137), are dissolved […]
