Abstract
Lithium-tin alloy is a potential material for tritium breeder/coolant in the fusion reactor. A research on the tritium diffusivity and solubility in the Li20Sn80 has been investigated by the in-reactor tritium release experiments. The not so low diffusivity and the middle level solubility make the Li20Sn80 a little relaxed on the tritium leakage problem, compared with Li17Pb83 and Flibe.
