HYDROGEN PERMEABILITY TECHNIQUE IN-SITU REACTOR IRRADIATION FOR ITER STRUCTURAL-MATERIALS

This work develops the technique of hydrogen diffusion parameters measurements in metal materials during the process of reactor irradiation. The possibility of irradiation stimulated hydrogen diffusion for 08Cr18Ni10Ti was obtained. Constants of diffusion, permeation and solution while tire process of irradiation were measured as a result of the work. Formally calculated activation energies of diffusion and permeation were obtained to decrease while the solution heat was increasing.
