摘要:

可控熱核聚變能是人類最理想的清潔能源之一，是解決人類能源和環境問題的根本途徑。目前，可控熱核聚變能的發展面臨諸多挑戰，偏濾器靶板作為磁約束核聚變裝置中的重要部件，其設計和制造是維持等離子體放電、實現核聚變反應堆穩定運行亟需解決的關鍵問題之一。作為等離子體轟擊最嚴重區域，偏濾器靶板經受著高能粒子流輻照和高熱負荷沖擊（10 MW·m-2穩態負荷和20 MW·m-2瞬態負荷），同時承擔著磁約束聚變裝置最主要的排熱功能。因此，研發具有優異性能的靶板材料是推動核聚變能發展的關鍵一步。目前，金屬鈹、碳基材料以及鎢基材料是主要的3種偏濾器靶板候選材料。基于國內外現有研究成果，論述了偏濾器靶板材料的選擇與研究進展，對比分析了3種候選材料的優勢以及存在的問題，以期為偏濾器靶板材料的選擇、研發提供借鑒。

Abstract:

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 present, 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 tokamak 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 analyzing 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.
