- Abstract
- The objective of this research is to develop iron phosphate ceramic (IPC)waste form with converter slag and test immobilization ability and physicochemical characteristics for IPC to be used for KCl-LiCl eutectic salt and off-gas scrubber solution wastes containing 99-Tc (or Re).We expect the cost of waste form production to decrease by using POSCO converter slag instead of iron oxide such as FeO, Fe2O3 and Fe3O4. In addition, we confirm a new possibility for development of iron phosphate ceramic with converter slag and immobilization ability for iron phosphate ceramics to stabilize radionuclide in LiCl-KCl eutectic salt and off-gas scrubber solution based on the results from characterizing physical properties by compressive test, SEM-EDS and XRD analysis, and estimating leachability by EPA 1315 and reductive capacity of IPC waste form by Ce(IV) and Cr(VI) method.
