Description
Summary:A concept of plasma-facing components (PFCs) of the TRT tokamak operating in the mode of long discharges and high average thermal load on the walls is presented. The PFC structure and problems and the relationship of the main parameters and processes that ensure the comfortable coexistence of the plasma and its surrounding walls are described. Construction solutions for the panels of the first wall and the divertor, which are performed on the basis of ITER technologies, are presented. The features of the use of liquid metals in PFC are discussed. Possibilities of alternative solutions for a divertor target are considered in detail.
