Abstract

Rates of He release from two kinds of simulated high-level radioactive waste glasses were measured in the temperature range from 573 to 753 K by a mass spectrometric method. Diffusion coefficients of He in the glasses were determined from the fractional release data. The diffusion coefficients were given as a function of temperature by the equations: In addition, solubilities of He in the glasses were determined from the measurement of the total amount of released He and found to be at 693 K and 1.7xl05 Pa He. The diffusivities and solubilities of He in the glasses were, respectively, several and an order of magnitude lower than silica, alkali silicate and Pyrex glasses, which properties are notable for the radioactive waste glasses.
