As the time for the dismantling of the nuclear power plant of Kori No. 1 in Koreaapproaches, preparations for the disposal of various types and large amounts of radioactive wastegenerated during the dismantling process are urgently needed. In this study, the conceptual designof a Mobile Compaction Facility for treatment and volume reduction of incombustible radioactivewaste, which occupies about 90% of the volume of nuclear power plant decommissioning waste, wasconducted. Differentiated design elements for improvement were derived by analyzing the problemsof existing radioactive waste compaction facilities. In order to determine the compacting force suitablefor the purpose of this study, a supercompaction experiment was performed by selecting simulateddismantled waste, and the International Standardization Organization (ISO) container and theoutline shape and moving parts of trailer-based mobile compaction type volume reduction facilitywere implemented as a 3D model. Based on this, a design concept of a variable stroke method thatcan be used for both 200 L and 320 L drums and utilizes limited installation space was introduced. The mobile compaction facility developed through this study has improved economic efficiency andoperational convenience compared to the supercompaction facility, and is expected to reduce the riskof radiation exposure of workers. Therefore, it is expected to be a facility for reducing the volume ofnuclear power dismantling waste that can be useful when dismantling nuclear power plants.
