Chemical treatment approaches to satisfy the discharge criteria for radioactive wastewater: Dissolved radioactive concrete liquor |
| 초록 |
Concrete building materials are one of the major radioactive wastes generated during the decommissioning of nuclear facilities. Mechanical and chemical treatment processes are available to separate the radioactive materials from the concrete. However these processes generate a large volume of secondary radioactive wastewater. In this research, we aim to remove the simulate radioactive nuclides using precipitation. The experiments were carried out using a simulated wastewater, formed by the dissolution of concrete within HCl, to which non-radioactive Cs, Sr, Co and Eu were added. Characteristics of precipitation were affected by the variation of pH and the injection of complexation agents. If it is treated effectively, this approach can be applied to the treatment of radioactive wastewater to satisfy the discharge criteria. |
