摘　　要：目前,U-Mo合金燃料是研究试验堆新一代燃料的研究重点。文章介绍U-Mo合金燃料在中国核动力研究设计院(NPIC)的研究现状和进展。NPIC于2006年正式开始研制U-Mo合金弥散燃料元件,几年间开展的研究工作主要有:U-Mo合金熔炼,γ相U-Mo合金粉末制备,(U-Mo)-(Al-Si)弥散燃料板制造工艺研究,U-Mo合金与基体材料、包壳材料和阻挡材料诸如Al、Nb、Zr、Mg等的相容性研究,Si添加到Al基体中对U-Mo/Al反应的影响以及U-Mo合金燃料成分分析及无损检测方法研究等。目前,NPIC已制备出基本满足要求的(U-Mo)-Al弥散燃料板,并计划于2010年前掌握满足技术要求的改进型(U-Mo)-Al弥散燃料板的制造技术。U-Mo alloy fuel is the research focus on new-type fuel for research and test reactor. The research status and progress of U-Mo alloy fuel in Nuclear Power Institute of China (NPIC) was introduced in this paper. U-Mo alloy dispersion-type fuel was started to study since 2006. In several years, much works have been done, including the smelting of U-Mo alloy, the preparation of γ-phase U-Mo alloy powder, the fabrication of (U-Mo)-(Al-Si) dispersion fuel plate, the compatibility between U-Mo alloy and cladding or matrix materials such as pure Al, Al-Si alloy, pure Nb, Zr alloy and pure Mg. In addition, the methods of elements analysis and non-destructive examination for U-Mo alloy fuel plate were studied. Based on these research works, the improved U-Mo dispersion fuel plates have been fabricated. The NPIC plans to master the fabrication technology of improved (U-Mo)-(Al-Si) dispersion fuel plates which satisfy the technical requirements by 2010.
