Progress in Research of International Thermonuclear Experimental Reator First Wall Materials

Controlled thermonuclear fusion energy is one of the most promising energy sources in the future. To make use of the fusion energy, there are still many technical problems. One of the most critical issues is the selection of international thermonuclear experimental reator first wall materials. The performance and selection of plasma facing materials are reviewed, and focusing on the analysis of research progress and development trends of beryllium, carbon-based materials and tungsten as a first wall material.
