摘要
The paper reviews the main mechanisms of hydrogen isotope accumulation in fusion devices: the implantation of particles from plasma into plasma-facing components (PFCs), followed by diffusion into the bulk of material, and capture into growing redeposited layers in areas of preferential deposition (co-deposition). The specific features of hydrogen isotope accumulation, depending on the selection of plasma facing material, are considered during the regular application of auxiliary coatings and the utilization of wall components based on liquid metals.
