摘要
本文研究了在H2+H2O混合气流下,UF4水解制备UO2粉末过程中的工艺条件,以及影响UO2粉末物性指标和产品含氟量的主要因素,通过试验确定了UF4水解制备UO2粉末的工艺参数.
In this paper,a study is made on the conditions of technological processes for producing UO2 powder by pyrohydrolysis of UF4,with catalytic hydrogen reduction taking place in H2-H2O gas mixture. Key factors affecting the physical performance of powder and the fluorine content in the product are discussed. Optimum parameters of the pyrohydrolysis reaction of UF4for preparing UO2are determined experimentally.
