Experiment and simulation on Zr 2 Fe bed for tritium capturing

concentration distributed along the bed axial at different time. This distribution profiles can be used to globally illuminate the concentration variation of hydrogen in the reactor within the whole reaction time scale. Comparing the experimental result of 1.27 days in the breakthrough curve, the results of numerical simulation can predict the curve of about 1.5 days began to breakthrough, although there were certain deviation (∼18%). The results can provide a feasible numerical model support for optimizing the tritium capturing bed design.
