熔盐电解法乏燃料干法后处理技术研究进展

Development of Pyroprocessing of Spent Nuclear Fuel by Molten Salts Electrolysis

熔盐电解法是目前最有前途的干法后处理技术,适合于处理氧化物和金属等不同类型乏燃料。熔盐电解法主要包括四个核心流程,即首端处理、电解还原、电解精炼和提取以及废物处理。本文以国际上最新的研究进展为蓝本,综述熔盐电解法乏燃料后处理技术的基本流程以及待解决的关键问题。

Pyroprocessing,based on molten salts electrolysis,is the most promising technology for dry reprocessing of different types of spent fuels,such as oxide and metallic fuels.Pyroprocessing technology involves four main processes,which are head-end treatment,electrochemical reduction,electrorefining and electrowinning,and waste treatment.This paper provides a state of the art review of the basic processes and unresolved key issues of pyroprocessing technology.
