Conductivity - Chemistry Relationship in Simulated Nuclear Waste Glass Melts

Abstract

Electrical conductivity of three simulated nuclear waste glass melts was measured over a wide range of temperatures, using a high-accuracy, calibration-free, coaxial-cylinders technique. Glass chemistries representing both low-activity and high-level wastes at Hanford and Savannah River sites were used. The temperature dependence of the conductivity of these glasses was presented. The conductivity values measured at 1150°C were compared to the conductivity values predicted from first-order mixture model.
