[en] Highlights: • Zeolite addition can trigger Stage III in solutions where it would be unexpected. • Four zeolites triggered Stage III behavior to varying degrees in three glasses. • Transient cyclical behavior was observed in some cases. • Stage III behavior observed at 22, 40, 70, and 90 °C for the first time. • Using an Arrhenius fit, E_a is found to range from 40 to 70 kJ·mol^-1. - Abstract: The corrosion of glass waste forms for nuclear waste immobilization is a key metric of their performance. Stage III behavior, the delayed acceleration of glass corrosion, remains the aspect of glass corrosion behavior potentially most impactful to long-term performance. Using the addition of various zeolite phases to trigger this effect, the properties of Stage III behavior were evaluated for three high-level waste glass compositions: SRL-202A, SON68, and AFCI. We show that Stage III behavior can occur at temperatures as low as 22 °C, with rate acceleration observed at 90 °C and 70 °C for all studied glasses, and at 40 °C and 22 °C for two of the compositions (SRL-202A and SON68). Using an Arrhenius fit, the activation energy of the process was found to be highly variable, with values between 39 and 68 kJ⋅mol⁻¹. Stage III behavior was triggered for each of the glasses studied by the addition of each of the four zeolites studied (i.e., Na-P1, Na-P2, analcime, and chabazite). The rates of alteration during Stage III varied very little, from 0.0058 to 0.023 g⋅m⁻²⋅d⁻¹ for the accelerated region immediately following zeolite addition. The acceleration was found to be transient, with the alteration rate decreasing and then accelerating again as the experiments proceeded. The solution composition was evaluated using the strong base/weak acid discriminator developed by Jantzen et al. and it was found that the addition of zeolites can overcome slightly non-optimal solution conditions for zeolite formation to trigger Stage III behavior.
