This study on the immobilization of high‐sodium‐bearing HLW in synroc indicates that (Na 0.5 Nd 0.5 )TiO 3 ‐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% Na 2 O show very well chemical durability and physical properties. The standard Synroc‐C formulation can incorporate only 2 wt% Na 2 O, so this study greatly improved the immobilization ability of sodium in Synroc‐related material.
