© 2019 National Research Center Kurchatov Institute. All rights reserved.At present the project of Kazakhstan materials science tokamak KTM is under implementation. In addition to solving problems i n the study of materials for fusion technologies, innovative design elements of the divertor are optimized. The design of the lithium divertor module based on lithium capillary-porous systems has been developed and successfully tested under real tokamak conditions. In this design, heat flows of high density are removed by the eutectic Na-K alloy. Requirements to improve the safety and compatibility of the divertor design with other in-vessel elements of the tokamak, cooled by water, and limiting thetemperature of the lithium receiving surface at <600 ºC at heat flows of 10-20 MW/m2 led to the new design solution for the experimental module of the divertor and the use of a new coolant - gas dispersed water flow (gas-water spray).The article describes and justifies the design solutions of the new version of the module, the parameters of the coolant and the cooling system scheme. Experimental results on determination of heat transfer coefficient for coolant based on gas-water spray are considered.
