以铅/铅铋冷快堆(LFR)为代表的第四代反应堆，因其安全性和核燃料可持续性受到广泛关注。由于反应堆条件下的铅基高温金属熔液（铅基熔液）比重大、温度高、腐蚀性强，使得用于驱动的主冷却剂泵设计制造难度大，可靠性和寿命低，成为制约LFR发展的技术瓶颈。寻找替代现有机械泵的主泵新原理、新结构及其设计与运行的理论方法被公认为是亟待解决的基础性科学问题。与机械泵相比，电磁泵没有运动部件，具有结构简单、可靠性高等优势，因而受到广泛关注。特别是基于磁流体驱动原理的超导电磁传导泵（SEP）因其磁场强、功率大、效率高，更是受到青睐。本项目围绕SEP的实际工程需求，研究磁流体耦合场的建模、分析与仿真，建立对角线高温超导电磁传导泵的数值分析模型；提出传导泵的设计、试验、运行的理论与方法；研制样机，并通过在实际试验回路的运行实验对理论成果进行验证与完善。从而为我国自主化新型铅/铅铋电磁泵技术的发展提供支撑。

The fourth generation of nuclear reactor, represented by lead or lead-bismuth fast reactor (LFR), has attracted worldwide attention for its outstanding safety and sustainability. However, the development is substantially detained due to the following technical problems: the lead-based high temperature metal molten fluid has large proportion, high temperature and strong corrosivity under reactor conditions, the main reactor coolant pump to drive high-temperature metal fluid is difficult to design and manufacture, has low reliability and life span. To find the theory and method for main pump with new principle, new structure to replace the mechanical pump and its analysis, design, experiment and operation is recognized as fundamental scientific problems to be solved. Compared with the mechanical pump, the electro-magnetic pump has simple structure, high reliability without motion components, and has attracted wide attention recently. Especially the superconducting electromagnetic pump which bases on the principle of magnetic fluid driven, is favored as its strong magnetic field, high power and high efficiency. According to engineering needs in the century of superconducting electromagnetic pump and based on the modeling, analysis and simulation of coupled field magnetic fluid, this project establishes numerical analysis model of diagonal HTS electromagnetic pump and puts forward the theory and method of its design, experiment and operation based on the test results. This project will pave the way for the research and development of the fourth generation nuclear power technology in China.
