The diffusion, solution and permeation coefficients of hydrogen isotopes in liquid Li-Pb which is a candidate liquid blanket material for fusion reactors were determined in the temperature range 573-973K using an unsteady permeation method. Each coefficiens was correlated to temperature as follows: D Li-Pb = 1.8 × 10 -8 exp(-11590/RT) [m 2 /s] (1) K Li-Pb = 2.1×10 -6 exp(-18700/RT) [1/Pa 0.5 ] (2) P Li-Pb = 1.8×10 -9 exp(-30290/RT) [mol/msPa 0.5 ] (3) The hydrogen permeation flux depends on the square root of pressure at 773-973K. Although the power of pressure declined below 0.4 when temperature was below 673K, the effects of surface resistance were neglected above 673K. The hydrogen solubility in liquid Li-Pbwas found to correlate with a Sievert's constant. We calculated a height-equivalent to theoretical-plate of a gas-liquid countercurrent extraction tower for tritium recovery rates in liquid Li-Pb to be H L = 7.0×10 -2 [m] (4).
