Examining the role of canister cooling conditions on the formation of nepheline from nuclear waste glasses
- Savannah River Site (SRS), Aiken, SC (United States). Savannah River National Lab. (SRNL)
Nepheline (NaAlSiO₄) crystals can form during slow cooling of high-level waste (HLW) glass after it has been poured into a waste canister. Formation of these crystals can adversely affect the chemical durability of the glass. The tendency for nepheline crystallization to form in a HLW glass increases with increasing concentrations of Al₂O₃ and Na₂O.
