Short-term corrosion of HLW glass in aqueous solutions enriched with various metal cations

Impact of iron chelators on short-term dissolution of basaltic glass

“…In an environmental context, studies about nuclear glass weathering have been largely reported in the literature. Short-term alteration experiments have been designed to determine initial dissolution rates (Luckscheiter and Nesovic, 2004;Fournier et al, 2014) while residual dissolution rates have been calculated for very long-term alteration experiments (Curti et al, 2006;Libourel et al, 2011;Gin et al, 2012Gin et al, , 2013Gin et al, , 2014. These short and long-term dissolution kinetics were investigated with respect to parameters such as temperature and pH (Pierce et al, 2008) and glass elemental composition http://dx.doi.org/10.1016/j.gca.2015.04.025 0016-7037/Ó 2015 Elsevier Ltd.

“…, and they have been coupled to studies of the alteration gel (Rebiscoul et al, 2005;Jollivet et al, 2008;Gin et al, 2015;Hellmann et al, 2015) or of secondary phases (Pelegrin et al, 2010). These experiments were performed in pure water, water enriched in elements from the glass (Luckscheiter and Nesovic, 2004;Thien et al, 2012) and in salt solutions (Godon et al, 1988;Abdelouas et al, 1993). The stability and dissolution behavior of bioglass, designed to form chemical bonds with living tissues (Souza et al, 2013), is of interest to the medical field.…”

Leaching behavior of CRT funnel glass

“…Glass corrosion in neutral water has been extensively studied in the field of nuclear waste glasses [22][23][24][25][26]. Since this requires long-range prediction, many studies use models of thermodynamic stability.…”

Radiation damage of alkali borate glasses for application in safe nuclear waste disposal

“…In particular, while borosilicate glasses matrices are usually applied for high level waste [24][25][26][27][28][29][30], borate glassy systems are not so far investigated: these matrices could be considered and optimized for the application in low (or middle) level waste immobilization. Moreover, to ensure a safe storage of vitrified nuclear waste, a deep analysis of microscopic radiation damage mechanism [31][32][33][34][35][36][37][38][39][40][41][42][43] besides corrosion and leaching behavior [44][45][46][47][48][49][50][51] are needed. In fact, the action of radionuclide ions combined with environmental conditions could produce an increased concentration of defects, causing volatilization of oxygen molecule, devitrification of the glassy matrices and worsening their ability for safe storing.…”
