    • 본발명은대입도암모늄우라네이트수화물결정과그 제조방법에관한것이다. 상기와같은본 발명에따르면, 종래의 ADU공정에서질산우라닐수용액과암모니아수를반응시키는것과달리, 질산우라닐수용액에기체암모니아를주입하여반응속도를제어함으로써, 생성되는암모늄우라네이트수화물결정의입경을크게만들수 있으며, 최종제조된암모늄우라네이트수화물결정은실험결과평균입도 9.32 내지 14.68 ㎛로종래의 ADU공정에의한결정에비해 100배이상이었다. 또한여액분석결과우라늄함량은 1 ppm 미만이었다. 본발명에의하여제조된암모늄우라네이트수화물결정의입경이종래에비해매우크므로후속공정인여과, 건조, 배소/환원공정에서의취급도종래의 ADU공정에비해훨씬쉽고, 후속공정의장치설계역시종래의공정에비해간단하며, 여과공정에서발생한여액에우라늄이거의포함되어있지않으므로우라늄회수를위한별도의화학처리공정이불필요하여설비투자비를크게절감할수 있는효과가있다.
    • 本发明涉及铀酸铵水合物的铵盐及其制备方法。 根据如上所描述的,对比的是硝酸,在传统的ADU过程用氨水铀酰溶液的反应的颗粒尺寸,通过在双氧铀溶液注入气态氨和产生铵的Ura碳酸盐一水合物晶体控制反应速率的硝酸本发明 和与由常规ADU过程如9.32决心14.68㎛实验结果的平均粒径创建更大,最终制造的Ura碳酸铵一水合物晶体是在超过100倍。 滤液分析显示铀含量小于1ppm。 随后的处理相比,铵浦碳酸盐粒径yijongrae过滤由本发明所产生的水合物的晶体,eseoui干燥,煅烧/缩小处理的处理也与以往相比ADU过程变得更加容易非常大,随后的处理的设备的设计也是一个常规的 而且由于过滤过程中产生的滤液中几乎不含铀,因此铀回收不需要单独的化学处理工艺,这可以大大降低投资成本。
