Abstract
Impedance spectroscopy is used to study the electrical conductivities of the borosilicate and aluminophosphate glasses containing analogs of the high-level fuel-processing waste of VVER-440. The electrical conductivities of the aluminophosphate and borosilicate glasses are found to be mainly determined by the sodium oxide concentration and to change significantly with temperature. An empirical equation is obtained to describe the electrical conductivity of the borosilicate glasses as a function of the sodium oxide concentration and temperature. The influence of the analogs of the HLW components on the electrical conductivities of the melts in the concentration range under study is insignificant.
