Scientific demonstration of controlled fusion, using deuterium and tritium as fuel, has been achieved during the 1990s in the US/TFTR and EU/JET tokamaks, the latter being the world's largest fusion device. The latest major undertaking in fusion power R&D is the International Thermonuclear Experimental Reactor, ITER, aimed at demonstrating self-sustaining fusion reactions in a practical machine. ITER is under construction in France. Among the critical issues facing ITER is the selection of materials for plasma-facing components, specifically the first wall of the vacuum vessel and the divertor. Current ITER design calls for beryllium for the vessel wall, carbon for the high heat flux targets of the divertor and tungsten elsewhere in the divertor.

20世纪90年代，美国/TFTR和欧盟/JET托卡马克装置已经实现了使用氘和氚作为燃料的受控聚变的科学演示，后者是世界上最大的聚变装置。聚变动力研发的最新重大项目是国际热核实验反应堆（ITER），旨在在实用机器中演示自持聚变反应。法国正在建设国际热核聚变实验堆（ITER）。 ITER 面临的关键问题之一是面向等离子体组件的材料选择，特别是真空容器的第一壁和偏滤器。目前的 ITER 设计要求容器壁使用铍，偏滤器的高热通量目标使用碳，偏滤器的其他地方使用钨。
