    摘要:

    镉(Cd)、硼(B)和一些稀有元素具有较大的热中子吸收截面,在核屏蔽吸收中子领域具有较广泛的应用前景。本文概述了用于核电站乏燃料“湿法”贮存用中子吸收材料的种类,论述了各种中子吸收材料的优点和不足。阐述了铝基碳化硼(B4C/Al)中子吸收材料的研究进展以及不同制备方法的优点和不足,进一步介绍了搅拌摩擦焊方法和扩散焊方法在连接B4C/Al中子吸收材料过程中的优势。在此基础上,对新型中子吸收材料在成分、结构设计方面进行了分析,对未来核屏蔽用中子吸收材料进行了展望。

    Abstract:

    Cadmium (Cd), boron (B) and some rare elements possess a large thermal neutron absorption cross section, which has a wide application prospect in the field of nuclear shielding neutron absorption. This paper summarizes the types of neutron-absorbing materials currently used for wet storage of spent fuel in nuclear power plants and discusses the advantages and disadvantages of these materials. The research progress of B4C/Al neutron absorption material, and presents different preparation methods and their merits and demerits. Besides, connecting methods of neutron absorption material are introduced, especially the advantages of friction stir welding and diffusion welding in fabricating metal matrix composites with high particle contents. Composition and structure design of neutron absorption materials are analyzed, and future nuclear shielding neutron absorption material is prospected.
