    摘要： PROBLEM TO BE SOLVED: To provide a method for stabilizing a nuclear material.SOLUTION: A method for stabilizing a nuclear material may include electrolytically reducing the nuclear material in a first molten salt electrolyte of an electroreducer to produce a reduced material. A reducer waste may accumulate in the first molten salt electrolyte as a byproduct of the electroreduction. After the electroreduction, the reduced material may be electrolytically dissolved in a second molten salt electrolyte of an electrorefiner to produce a purified metal product on a refiner cathode assembly of the electrorefiner. As a result of the electrorefining, a first refiner waste may accumulate in the second molten salt electrolyte and a second refiner waste may accumulate in a refiner anode assembly of the electrorefiner. The reducer waste from the electroreducer and the first refiner waste from the electrorefiner may be converted into a ceramic waste form, while the second refiner waste from the electrorefiner may be converted into a metallic waste form.

    摘要翻译： 要解决的问题：提供稳定核材料的方法。解决方案：用于稳定核材料的方法可以包括电解还原电解质的第一熔盐电解质中的核材料以产生还原材料。 还原剂废物可能作为电还原的副产物积累在第一熔盐电解液中。 在电还原之后，还原的材料可以电解溶解在电学纯化器的第二熔盐电解质中，以在电学纯化器的精炼器阴极组件上产生纯化的金属产物。 作为电解精炼的结果，第一精炼废物可能积聚在第二熔盐电解质中，并且第二精炼废物可能积聚在电学纯化器的精炼机阳极组件中。 来自电动除菌器的还原剂废物和来自电解精炼机的第一精炼废物可以转化为陶瓷废物形式，而来自电学纯化器的第二精炼废物可以转化为金属废物形式。
