We study tritium recovery from liquid lithium-lead (LiPb) droplets. In 2013, discovered the enhancement of recovery efficiency under droplets falling in a vacuum. Performed experiment was under short period laboratory level, therefore a continuous running verification was a challenge. From 2019, the continuous running experiment was performed on Oroshh-2 liquid metal test loop at National Institute for Fusion Science(NIFS). LiPb flow rate was between 0.2L per min and 0.4L per min, 350 degree C, 10 hours by ten times. Obtained dispersion coefficient was 2.0x10^(-7). The result was same order with that of 3.4x10^(-7) obtained in 2013, which verified the consistency of this method.
