However, the trapping and diffusion behaviour of hydrogen isotopes is not understood well. Since it is well known that vacancies in crystals are major trapping sites for hydrogen, the purpose of this study was to theoretically understand fundamental feature of the interaction between vacancies and hydrogen in carbides by density functional theory calculations., 20th International Conference of Fusion Reactor Materials}, title = {nteraction of Primary Precipitates in F82H steel with hydrogen atoms: Atomistic Calculation Based on the Density Functional Theory}, year = {2021} }
