Part of: Engineering Mechanics


A mixture of simulated high-level calcined waste (HLW) and Frit additives was hot isostatically pressed (HIPed) to a dense glass-ceramic waste form. A densification mapping software was developed for modeling HIP processing parameters such as soak temperature, soak pressure, densification rate, relative density, and calcine particle size. For a typical glass-ceramic waste form the model predicts the prominent densification/creep mechanism.
