Immobilization of Sodium-Bearing High-Level Radioactive Waste in Synroc Containing (Na0.5Nd0.5)TiO3-Type Perovskite
Abstract:This study on the immobilization of high-sodium-bearing HLW in synroc indicates that (Na0.5Nd0.5)TiO3-type perovskite can be used to incorporate a high content of sodium in synroc. Synroc samples containing 13.0 wt% waste oxide and 5.7 wt% Na2O show very well chemical durability and physical properties. The standard Synroc-C formulation can incorporate only 2 wt% Na2O, so this study greatly improved the immobilization ability of sodium in Synroc-related material.
