Abstract: PHREEQC is a geochemical model to study aqueous ion reaction equilibrium in water systems. In this paper, PHREEQC was used to calculate concentrations of main elements (Si, Na, B, Al, Sr, Cs, Fe and Nd) leached from simulated HLW-glass in solution. The experiments were preformed in deionized-water or simulated underground water at 90℃ or 150℃ under low oxygen atmosphere. The calculated results agreed well with the experimental results.
