Description
The phase states in the Pu-Si-O ternary system were investigated to understand the behaviour of Si impurity in MOX fuel and to assist in evaluating acceptable amounts of Si impurity in the fuel. Samples, which were mixed powders of PuO2 and SiO2 in three molar ratios, were annealed at 1623K-1973K as a function of oxygen potential. Two (Pu, Si) compounds, Pu4.67Si3O13 and Pu2Si2O7, were precipitated by annealing under a reducing atmosphere. The Pu4.67Si3O13 phase was precipitated in a wider composition range as compared with Pu2Si2O7.
