In fusion reactors, surfaces of plasma facing components (PFCs) are exposed to high heat and particle flux. Tungsten and Copper alloys are primary candidates for plasma facing materials (PFMs) and coolant tube materials, respectively, mainly due to high thermal conductivity and, in the case of tungsten, its high melting point. In this paper, recent understandings and future issues on responses of tungsten and Cu alloys to fusion environments (high particle flux (including T and He), high heat flux, and high neutron doses) are reviewed. This review paper includes; Tritium retention in tungsten (K. Schmid and M. Balden), Impact of stationary and transient heat loads on tungsten (J.W. Coenen and Th. Loewenhoff), Helium effects on surface morphology of tungsten (Y. Ueda and A. Ito), Neutron radiation effects in tungsten (A. Hasegawa), and Copper and copper alloys development for high heat flux components (C. Hardie, M. Porton, and M. Gilbert).

核融合炉において、プラズマ対向機器(PFC)の表面は、高い熱流束と粒子束に曝される。タングステンおよび銅合金は、それぞれプラズマ対向材料(PFM)および冷却管材料の主要な候補であり、その主な理由は高い熱伝導率、そしてタングステンについては高い融点にある。本論文では、核融合環境(高粒子束(TおよびHeを含む)、高熱流束、高中性子線量)に対するタングステンおよび銅合金の応答に関する最近の知見と今後の課題を概説する。本レビュー論文には以下の内容が含まれる:タングステン中のトリチウム保持(K. SchmidおよびM. Balden)、タングステンへの定常および過渡熱負荷の影響(J.W. CoenenおよびTh. Loewenhoff)、タングステンの表面形態に対するヘリウム効果(Y. UedaおよびA. Ito)、タングステンの中性子照射効果(A. Hasegawa)、ならびに高熱流束機器向け銅および銅合金の開発(C. Hardie、M. PortonおよびM. Gilbert)。
