In order to provide data for designing an Y hot trap to recover tritium from flowing liquid Li, diffusion coefficients and solubility constants of hydrogen in Li were determined with a capillary method between 500 °C and 650 °C. The diffusivity of hydrogen in Li determined here were correlated to DLi-H = 1.38 exp(-162[kJ/mol]/RgT). The correlation was consistent with one extrapolated from the previous Alire's correlation at higher temperature. Discrepancies among other previous diffusivity data were discussed in terms of the interaction of Li with H. The solubility determined was consistent with values extrapolated from the previous Sieverts' constant by Veleckis et al.
