Abstract
The advancement of selective separation and recovery method of actinoid is important subject for the advanced reprocessing and radioactive waste treatment. This method is regarded as a first step of the transmutation of long-lived nuclides, and the development of advanced separation techniques has been expected from the standpoint of nonproliferation, reduction of a burden to waste disposal, environmental remediation and effective utilization. Ion-exchange methods have been developed as a pioneer techniques, and the basic evaluation of selectivity and rationalization and compactness of ion-exchange process are extensively studied in various countries. Lately the development of more precise nuclide separation methods are expected for the advanced reprocessing and radioactive waste treatment. The advancement of selective ion-exchange techniques has important significance.
This special issue deals with (1) Purpose and impact of actinoid separation, (2) Separation characteristics and stability of promising ion exchangers and (3) Actinoid separation methods for advanced separation processes.
