Title: Remote system for the monitoring of molten waste glass

Leachability of a radioactive waste glass, the property of paramount concern, is affected by glass composition and operating conditions during vitrification. The current control system for a vitrification facility lacks the means for continuous monitoring of the glass composition. A remote and near-continuous method has been developed which is based upon the ability to correlate two ore more physical properties of the molten glass with its composition. Bubble-Rise-Velocity (BRV) viscometry was employed for the determination of the viscosity and differential pressure measurement was used for the determination of density. An empirical equation, which allows the calculation of viscosity of a Newtonian fluid from measured parameters, was developed. The remote and continuous monitoring of glass composition was successfully demonstrated.
