先进无盐二循环流程是我院开发20多年的乏燃料后处理流程。其中的铀净化循环的主要任务是对来自一循环的铀产品(1CU)作进一步纯化,以除去少量钚、镎和钌、锝等裂变产物元素,满足最终铀产品对α核素及γ去污等要求。铀净化循环热实验设备主要有预处理台架和萃取台架2个台架。预处理台架的功能是完成镎价态的调节以及2DF料液的调酸,萃取台架上配置2D、2E两个主工艺混 Advanced salt-free two recycling process is our hospital spent more than 20 years of spent fuel reprocessing process. The main task of the uranium purification cycle is to further purify the uranium product (1CU) from a cycle to remove a small amount of fission product elements such as plutonium, limonium and ruthenium and technetium to meet the requirements of the final uranium product for alpha-nuclide and gamma decontamination Other requirements. Uranium purification cycle thermal experiment equipment mainly pretreatment bench and extraction bench 2 bench. The function of the pretreatment bench is to complete the valence state adjustment and the acidification of the 2DF feed liquid. Two main process mixes of 2D and 2E are arranged on the extraction bench
