Abstract
An equipment for the volume-reducing treatment of a radioactive waste is disclosed. The equipment comprises means for drying and milling radioactive waste liquor, waste sludge, waste resin and the like generated from an atomic power plant, means for pelletizing the powder obtained from the drying and milling means and means for charging the pellet thus formed into a drum. The pelletizing means is a roller press consisting of a pair of press rolls, each having plural pockets formed on the surface thereof. Air vent grooves are also formed on the surface of each press roll so as to extend from the pocket in the rotating direction of the roll.
