Electrical Resistivities of Glass Melts Containing Simulated SRP Waste Sludges.

摘要

One option for the long-term management of radioactive waste at the Savannah River Plant is to solidify the waste in borosilicate glass by using a continuous,joule-heated,ceramic melter. Electrical resistivities that are needed for melter design were measured for melts of two borosilicate,glass-forming mixtures,each of which was combined with various amounts of several simulated-waste sludges. The simulated sludge spanned the composition range of actual sludges sampled from SRP waste tanks. Resistivities ranged from 6to 10ohm-cm at 500exp 0 C. Melt composition and temperature were correlated with resistivity. Resistivity was not a simple function of viscosity. 15figures, 4tables. (ERA citation 04:012606)
