초록
The flow characteristics of fluid were measured using radioactive tracer in pilot scaledigester with tray motion mixer. In consideration of the detection volume of the detector andthe size of the digester, 20 detectors were installed in the digester. The radioactive tracer eluted8 mCi of 68Ga from 68Ge/68Ga generator was injected into the digester bottom. After radiotracerinjection, the flow pattern was measured on the basis of the initial movement of the tracer untilits diffusion completely. Most of tracer moved to the wall along the bottom of the digester, andthen rose along the wall. The other tracer moved up along the mixer, and then moved to the walldirection along the surface.
