摘　　要：本文介绍了美国、俄罗斯、英国、欧洲铀浓缩公司、法国、中国和欧洲铀浓缩公司6个国家或公司现存贫铀的数量、贮存容器的类型、贮存方式和贮存现状以及各国对贫铀的安全管理策略。分析了贫铀再浓缩和作为燃料使用以及转化处理的前景,给出了贫铀转化成稳定的八氧化三铀(U_(3)O_(8))的技术及应用实践。贫铀作为一种有用的资源,在找到大规模利用贫铀之前,将贮存的DUF_(6)转化为更稳定、更易贮存的U_(3)O_(8)是一种最佳形式。This paper introduces the current quantity of depleted uranium,types of storage containers,storage methods,and storage status of six countries or companies,including the United States,Russia,the United Kingdom,Urenco,France,China,and European urenco company,as well as the safety management strategies of each country for depleted uranium.The prospects of reenrichment of depleted uranium and its use as fuel and conversion treatment are analyzed,and the technology and application practices of converting depleted uranium into stable uranium trioxide U_(3)O_(8) are provided.It is concluded that depleted uranium is a kind of resource,and conversion into tri-U_(2)O_(3) is the best safe storage method before large-scale use of depleted uranium is found.
