Static leach tests were carried out on a nuclear waste glass (SRL-165) at two different SA/ V- ratios of 0.85 cm^<-1>and 0.079 cm1 at 90℃. Fourier transform infra- red reflection spectroscopy revealed that Fe tended to precipitate on the surface of the glass when leached at 0.079 cm^<-1>, 90℃ for more than 14 days. X- ray photoelectron spectroscopy indicated that Fe which precipitated on the specimen surface was a mixture of Fe^<2+> and Fe^<3+>; the ratio of Fe^<2+>/Fe^<3+> would be determined by the redox conditions of surrounding water.
