First Wall and Blanket Design for a High Wall Loading Compact Tokamak Power Reactor

Among the specific limitations which tend to complicate a compact high wall loading (HWL) tokamak reactor design are high surface and nuclear heating, compactness leading to crowded components, unlikely breeding on the inboard side and frequent first wall/blanket replacement. This paper describes the mechanical, thermal hydraulic and tritium aspects of an improved blanket design for a high β (20%), high wall loading (∼ 10 MW/m²) compact fusion power reactor of 1000 MW_th power output.
