Re-evaluation of the Activity Concentration for a Volume Reduction of the Combustible Wastes in KAERI

According to the active operation of the nuclear facilities, a great amount of radioactive wastes has been generated, and also, the storage volume of the radioactive waste is considerably on the increase at the Korea Atomic Energy Research Institute (KAERI). At the moment, to secure a space in a waste storage facility approaching saturation, the radioactive waste treatment facility (RWTF) is now carrying out a project on a volume reduction of the wastes in storage. As a part of that project, a study on the treatment of a combustible solid waste is being conducted in the RWTF. All combustible wastes in interim storage at KAERI were collected into 200 liter steel drums in accordance with the original form without any treatment of them. Thus, in order to send them to the final disposal site, a repacking through a compaction treatment is a solution for a volume reduction of the combustible wastes. To do that, it is first necessary to conduct a radionuclide assessment of the combustible waste drums before a compaction treatment of them
