A system for treating radioactive waste employing a rotary mechanism which contains in its rotational path of travel a number of stages for the treatment, i.e., a stage of condensing a slurry of radioactive waste, a stage for drying the condensed waste and a stage for storing dried waste temporarily for feeding to a melting furnace. The rotary mechanism employs a number of containers for transferring the radioactive waste to and from the respective stages along the rotational path of travel.

System for treating radioactive waste

A microwave melter in which a material charged in a crucible is heated and melted by irradiation of microwaves, the melter including a melting furnace having an upper furnace body fixedly mounted on a support structure and a lower furnace body detachably connectable with the upper furnace body, a waveguide for guiding microwaves from a microwave generator toward the furnace, a crucible received rotatably and in a suspended state in the lower furnace body, and a feed pipe for feeding untreated material to the crucible.
