Crystallisation of a simulated borosilicate high-level waste glass produced on a full-scale vitrification line
Determined potential incorporation of High-Level-Waste radionuclides into identified crystals. Assessed effect of crystallisation on wasteform aqueous durability, identifying water-soluble molybdate phase and cristobalite/zektzerite as having negative effects. Confirmed that increasing alumina in UK HLW glass increases durability preventing amorphous phase separation and cristobalite crystallisation which may reduce long-term durability in a geological repository. Recognition of this and related work led to Lee giving invited Plenary at Intl. Conf. on Advanced Ceramics and Composites (Daytona, USA) in 2011 and £5.5M EPSRC award (EP/F017065/1, 2008-2013) to start the Centre for Advanced Structural Ceramics, Lee was PI and first Director.
