摘　　要：介绍了核乏料处理装置-加速器驱动次临界系统（ADS）的相关研究与发展现状，并综述了作为ADS散裂靶和冷却剂的液态铅-铋合金（LBE）的相关研究现状及应用优势，得出目前限制ADS发展的关键因素是铅铋合金与结构材料及焊接材料的相容性。同时，还针对LBE对316L、铁素体／马氏体钢的腐蚀机理及影响因素进行了总结阐述。鉴于北冶公司在316L、铁素体／马氏体钢、及相关焊接材料的研发生产方面具有的丰富经验，提出可通过优化成分、洁净化生产及改善热处理工艺等手段，提高ADS结构材料及焊接材料的耐蚀性。This article is primarily targeted to review the research and development status of Accelerator-driven System （ADS） which was used in a processor of nuclear waste materi- al, as well as the Lead-Bismuth Eutectic （LBE） used as the ADS spallation target and cool- ing agent. It was concluded that the current limited factor for the development of ADS was the compatibility between LBE and the structure material and welding material. Meanwhile, the corrosion mechanism and influence factors of LBE on the 316L and ferritic/martensitic steel were summarized in this study. Given the research experience on the related materials, methods for improving the corrosion resistance of structure material and welding material of ADS was provided, including optimization of alloy compositions, clean processing and heat- ing processing.
