俄罗斯氧化物乏燃料电沉积流程研究进展

高温熔盐干法后处理以熔盐作为电解质，通过电解精炼和电沉积回收核燃料中的铀和钚。目前，俄罗斯、美国、日本、韩国和欧盟等国均在积极发展乏燃料高温熔盐干法后处理技术的研究，其中俄罗斯的金属氧化物核燃料电沉积流程是经典的流程之一。本文对俄罗斯原子反应堆研究所（Research Institute of Atomic Reactors,RIAR）发展的氧化物乏燃料高温熔盐电沉积干法后处理的发展现状、流程及特点进行了综述。

Development of Oxide Fuel Electro-Winning Process at Russia

High temperature melt salts were used as an electrolyte in nuclear fuel dry reprocessing which can recover U and Pu from spent fuel by electro-refining and electro-winning. Russia, the United States, Japan, Korea, the European Union and some other countries are now actively developing melt salts dry reprocessing technology at present. Among them, Russia’s oxide fuel electro-winning process is one of the most classic. In this paper, the current status, technical routes and their features of oxide fuel electro-winning developed by Research Institute of Atomic Reactors were introduced.
