Processing reproduction method of radioactivity containing pollution products

摘要

PURPOSE:To lessen the volume of polluted material after processing, low control a radioactivity level of a substance dispersed at the time of the processing, and further obtain a solid material of reusable metal or ceramic and the like as a radioactivity generation source. CONSTITUTION:A radioactivity-containing polluted material is housed in a metal vessel, made a molding by push pressure molding, it is fed to the lower side of an edge part 9 of a plurality of electrodes 1-3, 1A-3A of a multi-phase arc generator 200, and here a molding 12 to be processed is melted by a plurality of arcs 10 generated between the electrodes. Next, the molten material 15 is poured into a mold 16 to coagulate, the mold 16 is opened and a solid material of a specified shape is taken out.
