IPC: G21C9/00
Filed: 1993-05-21
Abstract: PURPOSE:To simplify the facility by stirring steam containing solid state radioactive particles to cause collision and aggregation of the particles thereby eliminating a filter. CONSTITUTION:Steam discharged, while containing solid state radioactive particles, from a pressure vessel for nuclear core passes through a flow-in port 3 and strikes against a rotary vane 2 and then it is stirred by means of a stirring rod 3 and discharged into the water in a pool 5 through a nozzle 4. When the steam containing solid state particles is stirred, the stream line of the particles is varied to produce speed difference from the particles not influenced by the stirring thus causing collision and aggregation of the particles. In order to enhance the efficiency of aggregation, the stirring speed is increased and the relative speed is also increased by varying the shape of the stirring rod 3. Subsequently, the particles having increased particle size are passed through the nozzle 4 and the inertia thereof is increased before the particles are discharged into the water in the pool 5 and captured. This constitution enhances the efficiency in the capturing of required particles.
