目前,熔盐电解精炼过程是最为活跃的4种干法后处理技术研究方向之一。处理氧化物陶瓷组件的原理是用对铀、钚有强络合性能的络阴离子盐(如Cl-、F-、SO42-等)将氧化物乏燃料熔解在熔盐中。该方法存在的主要问题是熔融的络阴离子对电解系统中材料(如容器、电极等)具有严重的腐蚀性。美国阿贡实验室提出的金属锂还原氧化物电解精炼流程是比较典型的熔盐体系流程,此流程是在LiCl熔盐中先将乏燃料氧化物还原成相应的金属,然后再进行电解精炼回收铀钚。但 At present, molten salt electrolysis process is one of the most active research directions of four dry-process technologies. The principle of handling oxide ceramic components is to melt oxide spent fuel in molten salt with complex anion salts (such as Cl-, F-, SO42-, etc.) that have strong complexing properties with uranium and plutonium. The main problem with this method is that melted complex anions have serious corrosive effects on the materials in the electrolysis system (eg containers, electrodes, etc.). United States Argonne laboratory metal lithium reduction oxide electrolytic refining process is more typical molten salt system flow, this process is first in LiCl molten salt reduction of spent fuel oxides to the corresponding metal, and then the electrolytic refining recovery Uranium and plutonium. but
