New insights on the immobilization of radioactive acidic liquid waste and cesium in amorphous aluminophosphate waste form

Key Points

• The immobilization of radioactive acidic liquid waste was achieved with an amorphous aluminophosphate waste form, effectively capturing cesium.
• Studies demonstrated a high retention capacity, with cesium retention levels exceeding 90% across various testing conditions.
• Evaluation using advanced characterization techniques confirmed the structural stability and chemical integrity of the waste form under adverse conditions.
• These findings underscore the potential for improved management strategies for radioactive waste, calling for expanded applications of this material.
