Abstract
Because sodium has a tendency to form less-durable phases during the f abrication of synroc, it is very difficult to immobilize. This study s hows that synroc that contains Na2Al2Ti6O16-type freudenbergite can be used to incorporate sodium-bearing high-level radioactive waste. Synr oc samples that contain 5.0 wt% Na2O (11.5 wt% waste oxide, accordingl y) exhibit very good chemical durability and physical properties. The standard Synroc-C formulation can incorporate only 2 wt% Na2O. Therefo re, this study greatly improves the immobilization ability of sodium i n synroc.
