Abstract

Major requirements for a future fusion power plant are to ensure the extraction of the fusion power for electricity production and to provide the whole T necessary to sustain the thermonuclear reaction during the plant lifetime.

Blanket first wall and divertor targets have to be designed to sustain high heat flux in small surface regions facing the plasma; thick structures have to surround the ...
