Analysis of tritium kinetics of SIBELIUS beryllium

A tritium transport model called BETTY has been developed to describe and predict the kinetics of tritium transport in irradiated beryllium in fusion blanket applications. Some USA SIBELIUS experimental data were released and provided useful input data for tritium transport models and code development. An analysis of these USA SIBELIUS experimental data was performed in this paper. A comparison of the tritium kinetics results predicted by the model with those from the experiments shows reasonable agreements. In addition, a parametric sensitivity analysis for the variance of surface activation energies and diffusion coefficient is performed and the minimal effects are observed based on the modeling results.
