Abstract
This paper presents a model that allows to describe the absorption of hydrogen isotopes by the investigated sample under the following conditions: a thin sample with known geometric dimensions is saturated from the gas phase with hydrogen isotopes at the given temperature in a chamber of known volume and the initial hydrogen isotope pressure in the chamber. Using the developed model, it was possible to describe perfectly the experimental results on the absorption of a three-component mixture of hydrogen isotopes and to determine the interaction parameters of hydrogen isotopes with vanadium V4Cr4Ti alloy. In particular, the solubility constant and the diffusion coefficient of hydrogen isotopes in the alloy were determined, as well as the parameters of their Arrhenius dependences. In the future, the proposed model can be used to simulate the processes of hydrogen storage in nuclear reactor facilities (NR), thermonuclear reactors (TNR) and petrochemical industries.
