Ceramic and ceramic composites for first wall thermonuclear applications
The most serious safety and environmental consideration for nuclear fusion reactor development concerns the induced radioactivity of the first wall. The use of low activation materials would reduce considerably the potential risks and facilitate maintenance. Ceramic materials exhibit attractive properties such as low atomic number, high temperature capabilities and thermal shock-resistance, good thermal conductivity, and low specific weight. Graphite or carbon fibre reinforced carbon (CFC) are presently used as plasma facing armours in most tokamaks. Ceramic fibre reinforced SiC materials are presently under experimental investigation for structural application in future fusion reactors. The properties of the materials are reviewed with regard to potential applications in fusion reactors.
