ABSTRACT
In order to examine the process parameters for the vitrification of Low and Intermediate Level radioactive Waste (LILW) generated from nuclear power plants, measurements of several melt properties was performed for four selected glasses containing simulated waste. Electrical conductivity and viscosity were determined at temperatures ranging from 1123 to $1673^{circ}C$. The temperature dependences of both properties in the molten state showed a similar behavior in which their values decrease as the temperature increases. The values of the electrical conductivity and viscosity at a temperature of 1423K adopted in an induction cold crucible melter process were $0.27{sim}0.42$ S/cm and $9.8{sim}42$ dPas, respectively.
Key words: Vitrification, Low and intermediate level radioactive waste, Viscosity, Electrical conductivity, Induction cold crucible melter
