COOLED DIVERTOR MODULE FOR PLASMA TREATMENT

摘要

The invention relates to the thermonuclear power industry, particularly to a cooled divertor module for a tokamak type fusion reactor providing plasma treatment with liquid lithium. A cooled divertor module for plasma treatment comprises a cooled module base (1) for the flow of a liquid lithium film (14), the said module base (1) is made of a material with a thermal conductivity coefficient not lower than 350 W/m/K, is covered with a stainless steel layer with a thickness no more than 0.2 mm and ir oriented to the horizon at an angle of 15 to 45o and to the separatrix of the magnetic field at an angle of 10 to 25o. The separatrix crosses the module base (1) from above in its middle part; the liquid lithium feed system comprises a dosing system, placed outside a tokamak and connected with a liquid lithium reservoir (11) which includes bellows (9) with an adjustable drive mechanism (10), and a liquid lithium supply channel system (6) placed inside the tokamak and arranged in stainless steel sheets (4, 5) fitted with a heat exchange system (3), wherein each channel of the system (6) has a height of 0.1 to 0.3 mm and width of 2 to 7 mm and the distance between the channels is no more than 2 mm.
