This paper describes the facilities of the Institute of Atomic Energy of the National Nuclear Centre of the Republic of Kazakhstan (IAE NNC RK) (Kurchatov, Kazakhstan) designed to conduct studies on the interaction of hydrogen isotopes with materials of nuclear and fusion reactors with and without neutron irradiation. Experiments with sample irradiation are carried out at the LIANA facility, which is located at the IVG.1M reactor. The VIKA and TiGrA installations are designed to conduct experiments with materials before or after irradiation using the temperature-programmed desorption spectroscopy (VIKA), thermogravimetry, and differential scanning calorimetry (TiGrA) methods. The main results of some experimental studies are also presented.

The main goal of the carried out investigations was to examine behaviour of hydrogen isotopes (and evaluation of interaction parameters such as coefficients of diffusion, permeation and solubility) in materials of first wall and divertor of fusion facility in conditions approximate to its real working i.e. under simultaneous impact of hydrogen isotopes, high temperatures and reactor radiation.
