The high-temperature in vitrification process of radioactive wastes could cause radioactive technetium (99Tc) in secondary liquid wastes to become volatile. Solidified cementitious waste forms at low temperature were developed to immobilize radioacti

To predict the long-term fate of low- and high-level waste forms in the subsurface over geologic timescales, it is important to understand how the formation of an alteration phase or phases will affect radionuclide release from the corroding waste fo
