摘要在我国核电技术自主化发展过程中，堆本体、燃料组件和蒸发器等主要设备的关键材料自主化是一个重要的基础问题。对于高温气冷堆（high temperature gas-cooled reactor，HTGR），这些关键材料主要涵盖核燃料、高温金属、核石墨、压力容器材料、高温气冷堆制氢相关材料等。受国内材料研发和制造水平所限，高温气冷堆部分关键材料仍采用国外进口材料。该文针对我国高温气冷堆核能技术所需的关键材料技术开展战略研究，研究关键材料的内容和范围、制造产业链、表征和应用等，提出对高温堆技术发展具有支撑性作用的关键材料体系及其工程化技术，并给出技术发展规划和建议。
Abstract：The development of nuclear power systems in China requires that key materials for the reactor core and the main components be produced domestically. The key materials investigated in this study included the nuclear fuel, high temperature metals, nuclear graphite, pressure vessel materials, and high temperature gas-cooled reactor (HTGR) hydrogen production related materials. However, current domestic research and development and manufacturing capabilities require that some key HTGR materials still be purchased from abroad. Thus, China has sought to develop domestically produced key HTGR materials and technologies. This study analyzed the fundamental roles of various aspects of some key materials on the development of HTGR systems, including the content and scope, industry manufacturing chain, and characterization and application of key materials. The results indicate that research systems should be developed to support engineering development and industrial manufacturing of these key materials to support HTGR development. Future development schedules and suggestions are provided.
