Abstract

The behaviour of a simulant Magnox waste glass was investigated under the likely conditions of high temperature, very deep, geological disposal, viz. 760°C and 0.15GPa. Under these conditions partial crystallisation of the glass is observed with the formation of LnBSiO5 (Ln = Y, La, Pr, Ce, Nd, Sm and Gd), LiNaZrSi6O15 and a palladium (ruthenium) telluride phase. The significance of these findings is discussed in the context of the high temperature, very deep, geological disposal scheme.
