Zusammenfassung:The invention relates to the thermonuclear power industry, particularly, to a cooled divertor module for a tokamak type fusion reactor (tokamak) providing plasma treatment with liquid lithium. A cooled divertor module for plasma treatment comprises a 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, cooled, covered with a stainless steel layer with a thickness no more than 0.2 mm and oriented to the horizon at an angle of 15-45° and to the separatrix of the magnetic field at an angle of 10-25°; 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 0.1-0.3 mm and width of 2-7 mm and the distance between the channels is no more than 2 mm.
