In this paper, the methodology of the experiments on tritium generation and release from the Li15.7Pb lead-lithium eutectic under neutron irradiation is presented. Using the MCNP software, the neutron-physical calculations were performed. As a result of calculations, the power of energy release from the sample and from the design elements of ampoule device at the level of 1 MW thermal power are determined. Using the ANSYS software packages, thermophysical calculations for different temperature modes of eutectic at 1–6 MW stationary reactor power levels has been carried out. Based on the calculations a special irradiation ampoule device (AD) was developed. The cleaning and filling of the lead-lithium eutectic into AD were conducted. The methodical experiments to determine the irradiation parameters of eutectics and to determine the mass-spectrometric registration modes of tritium in ampoule device was performed. The preliminary results of the methodical experiments were presented.
