Steady-state impurity control, heat removal and tritium recovery by moving-belt plasma-facing components

Discussed in this paper is the application of "moving-belt plasma-facing components" for steady-state impurity gettering, heat removal and tritium recovery in fusion reactors. To minimize MHD effects as well as induced radioactivity, semimetallic or semiconductor materials such as C-C composite or SiC-SiC composite fabrics are proposed as the belt materials.
