This system allows carbonizing and then rapid cooling process in serial by using the radial multi-pass rotary technology, in order to separate solid materials themselves from radwastes including radioactive materials such as 3H or 14C etc. Then, The volume of radwastes can be reduced up to 10% of original volume. Rapid cooling prevents regeneration of secondary pollutions from the exhausted gas of the carbonizer. To treat the cooled gas with ashes exhausted from the chiller is another issue to solve in the future. We are trying to separate the radioactive materials from the cooled gas including ash.

The radwastes here is mixed evenly and distributed sequentially in the radial muti-spaced areas of a rotary drum. The radial multi-spaced area creates optimum conditions for even carbonizing, allows enough retention time, self-ignition and finally leads to high energy efficiency.
This, in turn, is necessary for reducing radwaste volume.
