本文介绍了面向等离子体的材料，主要是钨和关键问题的DEMO反应堆的研究活动的状态。简要介绍了氦对钨表面形貌的影响及其对聚变堆的影响，以及脉冲热对钨的影响。对于DEMO，稳态运行和重中子辐照的影响是重要的研究课题。简要总结了目前对这些问题的认识。最后讨论了螺旋系统向DEMO方向发展的问题。
This review paper presents status of research activity of plasma facing materials, mostly tungsten and critical issues towards DEMO reactors. A helium effect on tungsten surface morphology and its impact on fusion reactors and a pulsed heat effect to tungsten are briefly summarized. For DEMO, effects of steady-state operation and heavy neutron irradiation are important subjects to investigate. Present understandings on these are briefly summarized. Finally, issues of helical system towards DEMO will be discussed.
