Design of Plant-Scale Immobilization/Solidification Facility for Long-Stored Radioactive Isotope(RI) Wastes

Key Points

• The aim is to develop a cement-based immobilization facility for the long-term storage of radioactive isotope wastes, addressing safety concerns.
• Systematic design and performance verification of a cement-based solidification facility.
• Analysis of domestic laws, technical standards, and international guidelines (IAEA, NRC).
• Development of an automated, remote-operated processing system to minimize worker exposure.
• Integration of dual solidification structures for containers and enhanced radiation shielding design.
• Conducting experiments for optimal cement mix ratio, compressive strength evaluation, and long-term stability tests.
• Establishment of essential design requirements based on legal and technical analyses.
• Demonstration of improved structural reliability and operational safety of the facility.
• Validation of the long-term stability and regulatory compliance of the solidified waste.
