Isosaccharinic acid (ISA) is considered to affect the migration of radionuclide by the complexation, especially in the disposal of TRU wastes. In this study, we forcused on the effect of complexation of ISA with technetium (IV) because the imformation of complexation stability is not revealed. Therefore, we conducted solubility experiment of technetium (IV) in reducing condition and investigated the effect of ISA.
