AbstractAn assessment of the thermal control mechanisms applicable to solid breeder blanket designs under ITER-like operating conditions is presented in this paper. Four cases are considered: a helium gap; a sintered block Be region; a sintered block Be region with a metallic felt at the Be-clad interface; and a Be packed bed region. For these cases, typical operating conditions are explored to determine the ranges of wall load which can be accomodated while maintaining the breeder within its allowable operating temperature window. The corresponding region thicknesses are calculated to help identify the practicality of each concept and the design tolerances.
