■ Technical Objectives
→ Chungju Plant: Commercial operation of a soil washing process dedicated to imported heavy metal-contaminated soil
→ From heavy metals to radioactive contamination: Completion of a pilot system for radioactive contaminated soil decontamination based on the same principles
→ Participation in decontamination projects for radioactive contaminated concrete and soil generated during nuclear power plant decommissioning
→ Reference to and application of wet decontamination treatment technologies from the U.S. EPA
- Core Technology
- → Cs-137 (a monovalent cation) readily binds to porous fine particles and is primarily adsorbed onto particle surfaces
- → The majority of ¹³⁷Cs is concentrated in silt particles (<75 μm), which account for approximately 25% of the total soil
- → Consistent results have been confirmed in domestic research, including “Development of Decontamination Technology for Contaminated Soil in Nuclear Decommissioning Based on High-Pressure Washing”
- System Specifications
- → Processing Method: Wet Washing + Acid Washing
- → Equipment Size: 25 m × 15 m
- → Treatment Capacity: 0.5 ton/h
