U_3O_8氢还原制备UO_2技术研究

Study on the Technology of UO_2 Production through U_3O_8 Hydrogen Reduction

研制建立了卧式搅拌床系统,开展了U_3O_8氢还原制备UO_2及UO_2后续反应性研究,研究结果表明:部分来自国外的U_3O_8反应活性高;并研制建立了U_3O_8流化床试验系统,对上述条件下的U_3O_8流化质量进行了考察,结果表明U_3O_8具有良好的流态化性能。

Based on a horizontal stirred bed system, the production of UO2 through U3O8 hydrogen reduction and subsequent reaction of UO2 were studied. The results showed that the reactivity of some foreign U3O8 was high. The U3O8 fluidized bed experimental system was developed, the experiments of U3O8 hydroreduction and hydrofluorination were carried out, which showed that U3O8 had good fluidization performance .
