Abstract
Chemical decontamination techniques for decommissioning are divided into two groups : a predismantling system decontamination for a man-rem saving and a decontamination of dismantled components for reduction of radioactive wastes volume. At JAERI, efforts have been made to develop both the decontamination processes with H{sub 2}SO{sub 4}-Ce{sup 4+} (SC) and H{sub 2}SO{sub 4} solutions. In the chemical decontamination processes, it is required to reduce the amounts of secondary wastes as well as to achieve a high decontamination factor (DF). For this purpose, it is very important to select an optimum waste-solution treatment process from the point of characteristics and volume of waste solutions. This report describes outline of the SC decontamination processes, laboratory testing results for various waste treatments of the SC spent solutions such as electrodialysis, diffusion dialysis, ion-exchange resins. Finally, an optimum waste treatment process is proposed and discussed from the reduction of the amounts of final wastes. (author).
