Abstract

Crystallization kinetics of a simulated high-level waste (HLW) glass weremeasured and modelled. Kinetics of acmite growth in the standard HW39–4glass were measured using the isothermal method. Atime-temperature-transformation (TTT) diagram was generated from these data.Classical glass-crystal transformation kinetic models were empiricallyapplied to the crystallization data. These models adequately describe thekinetics of crystallization in complex HLW glasses (i.e., RSquared = 0.908).An approach to measurement, fitting, and use of TTT diagrams for predictionof crystallinity in a HLW glass canister is proposed.
