HIPed Tailored Pyrochlore-Rich Glass-Ceramic Waste Forms for the Immobilization of Nuclear Waste

“…As with the PCT-B procedure both samples behave in a similar manner. These leach rates are similar to those obtained for a glass-ceramic designed for immobilization of the high-level nuclear waste generated at the Idaho chemical processing plant (ICPP) HIPing conditions [20]. For the 7-day MCC-1 test, it is easily calculated that the leach rate in g/m 2 /d should be around 6 times the g/L extraction values in the PCT test if surface area/volume effects do not influence the results.…”

Structural and spectroscopic investigations on the crystallization of uranium brannerite phases in glass

“…Glass‐ceramics (GCs) have attracted recent attention as smart waste forms for the immobilization of actinide‐rich waste streams with processing chemicals . They combine the good chemical flexibility of glasses with the excellent chemical durability of ceramics, making them suitable composite materials for applications in nuclear waste management.…”

Development of brannerite glass‐ceramics for the immobilization of actinide‐rich radioactive wastes

“…[9][10][11][12][13][14][15][16] Glass-ceramics are an emerging candidate waste form matrix and have attracted considerable attention as they combine the chemical flexibility of glasses with the excellent chemical durability of ceramics, making them smart waste forms especially for the immobilization of some actinide-rich radioactive wastes which contain significant processing chemicals. [17][18][19] The glass-ceramic composite products can be achieved using the glass-forming components present in the waste, along with appropriate additives, to form a relatively durable glass to accommodate processing chemicals and the desired durable crystalline phases to host the actinides within their crystal lattices. [17][18][19] Ideally, the chosen ceramic phases should meet some basic requirements, e.g., capable of incorporating certain amounts of actinide ions in their crystal lattices, having good radiation resistance and long-term chemical durability.…”

Some durable titanate mineral phases identified in Synroc, [6][7][8][9][10][11][12][13][14][15][16] e.g., zirconolite and pyrochlore, have been considered for such an application.…”
