MAGNETIC INDUCTION ROTARY DIVERTER OF RESISTANT TO HIGH HEAT LOAD TYPE

摘要

PPROBLEM TO BE SOLVED: To overcome the problem that conventional diverters cannot be used at the critical heat flux (20 to 30MW/m2) or higher and that the space occupied by equipment is limited because they combines heat receiving, heat removal and exhaust functions due to unilateral heating, a low design tolerance for burnout, a large incidence amount of a high-density plasma particle beam in a vacuum and a high spatter attrition rate. PSOLUTION: A magnetic induction rotary diverter of a type resistant to high heat and load can be used at 20 to 30 MW/m2 of the thermal flux from plasma in the vicinity of the critical heat flux. The diverter rotates at a uniform speed by using a toroidal magnetic field of a nuclear fusion reactor of a tokamak type to rotate and drive a heat receiving surface which receives the thermal flux from the plasma and locate a rotary cylindrical target on the outer periphery of a cooling tube brought to a standstill through the medium of a gallium liquid metal layer.
