<p>Radioactive wastes from a nuclear reactor plant are dried into powder and compacted into pellets. The resultant pellets are conveyed to a sealed vessel (54) by a belt conveyor system (48, 50, 52). To control the spacing of the pellets on the belt conveyors and thereby control the radioactive dose around the belt conveyors, two vibratory feeders (42, 44) are arranged in series and operated so that the rate of loading of the pellets onto the belt conveyors is always kept lower than a predetermined level. By the use of the vibratory feeders, adhesion of radioactive powder removed from the pellets onto the belt conveyors is also prevented.</p> |
