It is expected that the development of thermonuclear fusion will be able to easily satisfy the energy needs of humanity. There are enough fuel reserves for the fusion reaction: tritium can be bred via a 6Li(n,α)3H reaction from lithium, which is common in nature, and deuterium is quite easily extracted from seawater. One of the problems on the way to implement thermonuclear fusion today is the search for and development of breeder materials that can withstand the high radiation and energy loads that are expected in a long-pulsed fusion devices. Various types of lithium-containing ceramic materials are currently being actively studied for use as a breeder material in helium-cooled breeder blanket concepts. This study focuses on the methodology and results of calculations of tritium residence time in the samples of biphasic lithium ceramic pebble bed containing nominal 65 mol % lithium orthosilicate and 35 mol % lithium metatitanate (pebble diameter 0.25 -1.250 mm). The values of the tritium residence time obtained as a result of modeling the release of tritium from ceramics within the framework of the diffusion-desorption model have a temperature dependence of lgτ = -1.374+1676/t. They are in good agreement with the literature data, suggesting that the tritium residence time increases with increasing open porosity.DOI
