Mineralization of Radioactive Wastes by Fluidized Bed Steam Reforming (Fbsr): Comparisons to Vitreous Waste Forms, and Pertinent Durability Testing

“…• The responses of long-term crushed glass tests (ASTM C-1285, PCT) have been related to shorter term, higher temperature, VHT responses, e.g. the HLW Environmental Assessment (EA) glass reaches the same stage of durability within 56 days at 20,000 m -1 or >313 days at 2000 m -1 when tested by PCT at 90°C [149] or within 6 days when tested by VHT at 200°C [149].…”

“…• The forward rate of a short-term monolith test (ASTM C-1220, MCC-1) has been shown to be equivalent to the forward rate of the single pass flow though (SPFT) test [86,149].…”

Colloid-Associated Radionuclide Concentration Limits: ANL

“…4) are consistent with a smectite clay. Other examples of clay colloids formed in the glass corrosion tests can be found in the following references: Bates et al ( , 1996; Buck (1994a, 1994b); Buck et al (1993Buck et al ( , 1994; Buck and Bates (1999); Cunnane and Bates (1991);. Clay colloids can be readily identified in the TEM, as they often produce oblique textured electron diffraction (OTED) patterns when tilted.…”
