As a results of high probability of hydrogen isotopes permeation through the materials during high-temperature reactor operation, the interaction of hydrogen isotopes with metallic structural materials proposed to be used for fusion reactor designing, is of a great importance for safely considerations. Determining the parameters of the interaction between heavy hydrogen isotopes and various materials, including diffusion solubility and permeation of tritium trough structural materials, is therefore essential to an accurately calculate recycling, out gassing, loading, permeation and hydrogen embrittlement. The permeation tests were made at IFIN Bucuresti for radioactive protection rules reasons, inside of a special glove-box, at different tritium concentration values.
