We have studied the tritium recovery by using freefall PbLi droplets in vacuum. To apply this method for the practical fusion reactor, a huge flow rate of liquid PbLi must be handled. The size of droplets, in due course, must be enlarged to avoid enormus recovery device size. The recovery ratio of tritium from a PbLi droplet is approximately reciprocal to the droplet size. To maintain same recovery ration with large droplet size, the flying time of droplet mut be extended. To obtain sufficient flying time, we propose the upjet ejection of PbLi droplet. The upjet droplet is so far not evaluated. We verified the feasibility by using hydrostatic theory, and droplet observation.
