Abstract
Radioactive substances released as nuclear power plant accident can contaminate soil in a wide area. Soil washing is used as decontamination technique for Cs-contaminated soil, which exhibits short processing time and maximization of Cs removal rate by applying flocculating agents. However, soil washing generates secondary waste in the form of sludge/slurry. In this context, proposed a method of pelletization and solidification of powdered waste to facilitate treatment/disposal of the Cs-contaminated fine soil (secondary waste). In addition, by characterizing the prepared waste form, it was examined whether waste form satisfies Waste Acceptance Criteria for disposal facilities in South Korea.
