Abstract: As the first layer of engineering barriers, glass will be irradiated by electron in the long-term disposal of high level radioactive waste (HLW). It is significant to study the electron irradiation effects of glass for the safe disposal of HLW. In this paper, the effects induced by electron irradiation were studied in situ by transmission electron microscope (TEM). Under electron beam, the phase separation occurred very soon in both glasses, which was correlated to the network relaxation processes as a consequence of diffusion and desorption of sodium species during electron irradiation. A simple structural model was introduced to explain the difference in separated phase in two different glasses, which indicates that the phase separation induced by electron irradiation is closely related to the sodium contents in the glass sample.
