We report the experimentally obtained overall tritium extraction efficiency from liquid Lithium-Lead by the tandem extraction methods. It extracts the dissolved tritium at first stage by the release from a partial flow in an inlet pipe, and then from the release from droplets.Pre-estimated overall efficiency was 0.7. The obtained results were between 0.8 and 0.9 which exceeded 0.1 and 0.2 than the estimated values. Experiments were performed with the 2.3mm diameter, on the other hand, calculation was performed with dispersion coefficient previously obtained from 1.9 mm droplet. The results suggest that the dispersion coefficient of a 2.3 mm droplet is larger than that of 1.9 mm.
