We proposed the used of High Temperature Gas-cooled Reactors (HTGR) as a tritium production device, which produces tritium by $^{6}$ Li(n,)T reaction, for initial fusion reactors. Concentrating of $^{6}$ Li suppresses undesirable leakage of produced tritium into reactor coolant. In this study, the effect of $^{6}$ Li concentration difference on the amount of the tritium leakage and the tritium production efficiency was investigated.
