可控热核聚变能是人类最理想的清洁能源之一,是解决人类能源和环境问题的根本途径.目前,可控热核聚变能的发展面临诸多挑战,偏滤器靶板作为磁约束核聚变装置中的重要部件,其设计和制造是维持等离子体放电、实现核聚变反应堆稳定运行亟需解决的关键问题之一.作为等离子体轰击最严重区域,偏滤器靶板经受着高能粒子流辐照和高热负荷冲击(10 MW·m-2稳态负荷和20 MW·m-2瞬态负荷),同时承担着磁约束聚变装置最主要的排热功能.因此,研发具有优异性能的靶板材料是推动核聚变能发展的关键一步.目前,金属铍、碳基材料以及钨基材料是主要的3种偏滤器靶板候选材料.基于国内外现有研究成果,论述了偏滤器靶板材料的选择与研究进展,对比分析了3种候选材料的优势以及存在的问题,以期为偏滤器靶板材料的选择、研发提供借鉴.
Material Selection and Research Progress of Divertor Target Plate in Nuclear Fusion Device
As a safe and sustainable clean energy,controllable thermonuclear fusion energy is an ideal energy to meet the needs of human beings in the future.At pres-ent,the engineering and commercial application of nuclear fusion energy still faces many technical problems.Among them,the design and manufacture of the divertor target plate,an important component in the nuclear fusion device,is one of the key problems that need to be solved urgently to realize the stable operation of the nuclear fusion reactor.The divertor target plate is the most intense area of plasma bombardment.It is subjected to huge particle irradiation with high flux and high thermal load impact.Besides,the divertor undertakes the main heat removal function of the to-kamak device,with extremely harsh service environment.Therefore,the research and development of divertor target materials with excellent performance is a key step to promote nuclear fusion research to practicality.At present,metal beryllium,carbon-based materials and tungsten-based materials are the main three divertor target materials.This paper discusses the selection and research progress of these materials,comparing and ana-lyzing the advantages and disadvantages of various materials used in the divertor target plate as well as the existing technical problems.The aim is to provide a reference for promoting the design and manufacture of the divertor target plate.
