Abstract

This work presents the preliminary experimental data on the study of gas release from two-phase lithium ceramics Li₄SiO₄-Li₂TiO₃ under neutron irradiation conditions. Experiments were carried out at the WWR-K research reactor (Almaty, Kazakhstan) for ∼4.3 days. The total neutron fluence during the irradiation was ∼1.8·10¹⁹n/cm². In the course of irradiation, two experiments on ceramics heating during irradiation and two experiments with hydrogen isotopes (H₂ and D₂) supply into the experimental chamber with the sample were performed at a temperature of 680 °C and reactor power of 6 MW. During the entire irradiation, the gas composition in the continuously evacuated ampoule device with samples was recorded. The obtained dependences of the release of tritium-containing molecules and helium during the experiment were qualitatively analyzed.
