Model calculation of tritium release behavior from lithium titanate
چکیده انگلیسی

Among the various tritium transport processes in lithium ceramics, the importance and the detailed mechanism of surface reactions still remains to be elucidated. The dynamic adsorption and desorption (DAD) model has been developed to calculate the tritium release behavior from Li2O surface. In the DAD model, the tritium release behavior is considered to be controlled by the surface coverage of adsorbed species, such as OH−, O2−, H−, determined by the H2 and H2O concentrations in the gas phase and the temperature. In a previous paper, the tritium residence time on the Li2O surface was calculated from the model, and the calculation results were compared with the experimental results. It was shown that the calculation results agreed well with the experimental results. In the present paper, a model for the surface behavior of tritium release from Li2TiO2 was constructed, according to the concept of the model for Li2O. The calculation results are compared with the experimental results and the validity of the tritium release mechanism assumed in the model is discussed.
