Electrochemical processing of spent nuclear fuel in molten chloride salts results in radioactive salt waste. Chlorine removal from the salt has been identified as an effective and efficient first step in the management of high-level waste. In this work, a simple salt was dechlorinated with a phosphoric acid phosphate precursor, resulting in a glassy dechlorinated product. The dechlorination efficacy was evaluated in air and argon environments. This work serves as an initial step to advance the Technological Readiness Level of H₃PO₄-based dechlorination step toward implementation of iron phosphate waste forms to immobilize electrochemical fuel reprocessing salt waste streams.

使用磷酸前体对电解精炼盐废物进行磷酸盐脱氯

在熔融氯化物盐中对乏核燃料进行电化学处理会产生放射性盐废物。从盐中去除氯已被认为是管理高放废物的有效且高效的第一步。在这项工作中，用磷酸磷酸前体对简单盐进行脱氯，产生玻璃状脱氯产物。在空气和氩气环境中评价脱氯效果。这项工作是推进基于 H ₃ PO ₄的脱氯步骤的技术准备水平的第一步，旨在实施磷酸铁废物形式以固定电化学燃料再处理盐废物流。
