摘　　要：铅基快堆是我国第四代核能系统重点部署堆型之一,液态铅铋合金因具有良好的中子学、热工水力学和安全特性,被用作加速器驱动系统和第四代核能系统铅基快堆的冷却剂。然而,有研究表明,铅铋冷却剂中存在杂质会降低结构材料的抗腐蚀性能,严重时还会显著降低冷却剂的热工、水力特性,给反应堆的运行带来安全隐患。因此,文章针对铅铋合金中杂质的来源、国内外分析研究现状展开了充分调研及总结对比,指出了当前分析方法面临的主要问题,可为铅铋合金中杂质分析方法的建立提供一定的建议。Lead based fast reactors are one of the key deployment types in China’s fourth generation nuclear energy system.Liquid lead bismuth alloy is used as a coolant for accelerator drive systems and lead based fast reactors in the fourth generation nuclear energy system due to its excellent neutronics,thermal hydraulics,and safety characteristics.However,studies have shown that the presence of impurities in lead bismuth coolant can reduce the corrosion resistance of structural materials,and in severe cases,it can significantly reduce the thermal and hydraulic characteristics of the coolant,posing a safety hazard to the operation of the reactor.Therefore,this paper conducts a thorough investigation and comparison of the sources of impurities in lead bismuth alloys,as well as the current analysis and research status at home and abroad.It points out the main problems faced by current analysis methods and provides certain suggestions for the establishment of impurity analysis methods in lead bismuth alloys.
