“…Materials science studies conducted as part of the implementation of international programs for the creation of fusion reactors ITER and DEMO have shown that one of the best materials for use as an PFM (plasma-facing material) [1] in controlled fusion plants is liquid lithium and materials based on it [2,3,4]. The use of liquid lithium as a plasma-facing material is especially promising if lithium is enclosed in a so-called capillary-porous system (CPS) [5,6].Currently, there are many studies in the world conducted with lithium CPS, which once again confirms the interest in this material [7,8,9,10,11,12,13].Work on this topic is also being carried out at the Kazakhstan Materials Science Tokamak KTM [14,15,16,17,18,19,20]. The installation is currently the only tokamak in the world designed to solve problems in the field of thermonuclear materials science.…”

This work is devoted to testing a lithium CPS based on carbon fabric reinforced with carbon nanotubes under conditions of thermal and radiation loads. The paper considers and analyzes: the properties of carbon nanotubes and methods of their synthesis, the nature of the interaction of carbon materials with liquid lithium at different temperatures. A description of all the main stages in the manufacture of lithium CPS based on carbon fabric reinforced with carbon nanotubes is given. Microstructural studies of a manufactured lithium CPS sample based on carbon fabric reinforced with carbon nanotubes are presented. Studies have shown that a carbon fabric with a fiber surface reinforced with carbon nanotubes is completely wetted by liquid lithium. The developed technology is fully suitable for the manufacture of lithium CPS samples for further research. The results of experiments on the interaction of lithium CPS based on graphite fabric reinforced with carbon nanotubes with hydrogen isotopes under thermal and radiation loads are presented.
