Features of the in-situ experiments on studying of tritium release from lithium ceramic Li2TiO3 using vacuum extraction method

2021

Abstract The paper presents the results of reactor experiments with lithium ceramic Li2TiO3 performed at the WWR-K research reactor (Almaty, Kazakhstan). A qualitative analysis of the experimental results is presented. The following general results are obtained from the experiments performed by the vacuum extraction method: • Almost no tritium is released in the form of tritium water vapor, and the processes associated with tritium interaction with water vapor can be excluded from the consideration; • a significant amount of tritium is released as T2 molecule; • in long-term irradiation, a significant growth of tritium release in the form of T2 molecule with the time of irradiation is obser…
