Description

Volatile behaviors on ceramic spent filters at high temperature were studied using TGA equipment in order to find optimal immobilizing processes. It was found that cesium does not volatilized at over 1000 .deg. C, and rhenium starts to volatilized at near 700 .deg. C. However, volatilized mass could not be found exactly since moisture was absorbed to AgX during the trapping of iodine. The analysis of SEM-EDX and XRD were performed, to confirm that cesium was converted to pollicite, rhenium to calcium rhenium oxide, and iodine to AgI
