Description

technical field [0001] The invention belongs to the field of radioactive waste treatment, and in particular relates to high-level radioactive waste concentration equipment. Background technique [0002] In recent years, the world's energy shortage and safety issues have become increasingly prominent, and nuclear power is ushering in new opportunities for development. In order to ensure the sustainable development of nuclear energy, it is necessary to establish a complete nuclear fuel cycle system that matches the development of nuclear energy. my country has always adhered to the closed-cycle policy of nuclear fuel, reprocessing spent fuel and recovering useful elements in it, which has greatly improved the utilization rate of nuclear fuel resources. At present, the PUREX process is the only industrialized reprocessing process. Through this process, U and Pu in spent fuel can be recovered, and other components mainly enter high-level waste liquid. High-level waste liquid h...
