【摘要】 液态锂铅包层是国际上普遍关注和最有发展潜力的聚变堆包层概念设计之一,而包层材料是液态锂铅包层的核心问题之一。目前,液态锂铅包层普遍选用低活化铁素体/马氏体钢(RAFM钢)作为结构材料,液态锂铅作为中子倍增剂及氚增殖剂。另外,部分设计采用了耐高温、电绝缘流道插件作为功能材料.以降低磁流体动力学效应及提高冷却剂出口温度(高于700℃)。为适应液态包层的发展需求.中国科学院等离子体物理研究所FDS团队联合国内外相关研究单位,进行了具有中国自主知识产权的中国低活化马氏体钢(CLAM钢)及液态锂铅包层功能材料研发.并开展了锂铅热对流及强迫对流回路的设计、研制及腐蚀实验研究,以研究液态金属锂铅的流动特性及其与结构和功能材料的相容性。同时建立了聚变堆材料数据库平台.为促进中国聚变堆液态包层及材料技术的研究和发展提供数据支持。

【Abstract】 The liquid Li-Pb blankets have become the most promising conceptual blan- kets in the world.Materials selection and development are one of the key issues for liquid Li-Pb blankets.Currently,the reduced activation ferritic/martensitie (RAFM) steels are chosen as the candidate structural material and liquid Li-Pb as neutron multi- plier and tritium breeder.And in some designs,the flow channel insert (FCI),which can bear high temperature and have low electric conductivity,is adopted as the functional material to enhance the coolant outlet temperature and reduce the magnetohydrodynamic (MHD) pressure drop.In order to meet the requirement of liquid blanket development, the China low activation martensitic (CLAM) steel and functional materials for liquid blanket are being developed in Institute of Plasma Physics (ASIPP),Chinese Academy of Sciences under wide collaboration with other institutes and universities in domestic and overseas.Meanwhile,liquid Li-Pb thermal and forced convection loops were designed,manufactured and corrosion experiments were carried out to study the flow characteristics and the compatibility of liquid Li-Pb with structural and functional mate- rials.In addition,a fusion material data management system was built to be a useful tool to accelerate the research and development on fusion blanket design and material technology.
