摘　　要：金属燃料具有增殖比高、后处理流程简单、安全性好、处置长寿命锕系核素方便、可组成一体化快堆核电站等优点,是快堆燃料的理想选择。早期金属燃料由于材料选型和元件设计上的不足,使用燃耗较低(不超过5at.%)。后来,国际上其他国家(主要是美国、日本、韩国等)通过不断的材料选型和元件设计优化,基本可以确定金属燃料燃耗最高可到20at.%。针对我国一体化快堆U-TRU-Zr金属燃料选型和高燃耗的研发需求,调研了国内外快堆金属燃料的研发现状,提出了高燃耗金属燃料关键问题和解决方案,制定了我国一体化快堆高燃耗U-TRU-Zr金属燃料的研发技术路线。Metal fuel has high breeding ratio,simple post-processing procedures,good safety,convenient disposal of long-lived actinides,and can be integrated into integrated fast reactor nuclear power plant,making it be an ideal choice for the fuel of fast reactors.Early metal fuel had low burnup(lower than 5at.%)due to shortcomings in material selection and component design.Later,through continuous material selection and component design optimization,the highest burnup of metal fuel has reached 20at.%in international research(mainly in the United States,Japan,and South Korea),and the reliability of high burnup application has basically been determined.In response to the research and development needs of U-TRU-Zr metal fuel with high burnup for China integrated fast reactor,the current status of fast reactor metal fuel research and development at home and abroad was surveyed,and key issues and solutions for high burnup metal fuel were proposed,and a research and development technology roadmap for high burnup U-TRU-Zr metal fuel for China integrated fast reactor was formulated.
