The present invention relates to a system for reducing a volume by using a superheated vapor generated from a superheated vapor generator, so as to carbonize and dry low-level radioactive wastes, the system comprising: a reheated vapor generator for generating the superheated vapor by heating mist sprayed from an atomizer, and then discharging the same to a vapor supply pipe; a drying furnace for carbonizing and drying the fed low-level radioactive wastes by primary vapor and the superheated vapor, which are supplied from the reheated vapor generator, and then cooling the carbonized and dried low-level radioactive wastes to a predetermined temperature; a heat exchanger for exchanging the heat of the vapor discharged from a vapor discharge pipe after the low-level radioactive wastes are carbonized and dried in the drying furnace, then supplying the heat-exchanged vapor to the reheated vapor generator through a vapor delivery pipe, discharging, to a condensate water delivery pipe, condensate water generated after the heat exchange of the discharged vapor, and supplying heat-exchanged cooling water to the drying furnace through a cooling water delivery pipe; and a cooling tower for cooling the cooling water, heat-exchanged in the heat exchanger and circulated in the drying furnace, and then delivering the same to the heat exchanger again. |
