Analytical methods have been developed and evaluated for supporting the characteriza-tion tests of actual high-level radioactive waste glasses. The experiments were carried out by using a simulated waste glass sample and the NIST Standard Reference Materials. Sample solutions for the determination of Si and B were prepared by decomposition of a 0.1 g powdered glass sample by fusion with sodium peroxide, and then the solutions were analyzed by the inductively coupled plasma atomic emission spectroscopy (ICP-AES). Other sample solutions both for the atomic absorption spectrometry (AAS) determination of Li and Na and for the ICP-AES determination of Al, P, Ca, Fe, Zn and Zr were prepared by the decomposition of a 0.1 g powdered glass sample with hydrofluoric acid-per-chloric acid mixture. Four kinds of the NIST Standard Reference Materials were ana-lyzed to evaluate the reliability of the analytical methods. Consequently, it was evident that the repeatability of these methods were less than 6%, and that the analytical values of the NIST Standard Reference Materials were within 7% of their certified values.
