| Research Abstract |
Establishment of tritium migration model in solid breeder materials was purposed. Tritium release from Li2TiO3 was controlled by diffusion process due to uniform tritium distribution in Li2TiO3. Tritium trapping processes by irradiation defects and as hydroxyl groups were also found. The kinetics of tritium migration in these processes was evaluated. Tritium release behaviors for lithium enriched Li2TiO3 were also evaluated to understand tritium migration processes in advanced breeder material.
