摘　　要：通过推导计算得出:在考虑杂质累积影响的情况下,萃余溶液循环利用20%不至于对二氧化铀产品质量造成影响,生产也完全有能力接纳萃余溶液循环利用带入的水量。在萃余溶液循环利用20%的生产过程中,每月跟踪分析二氧化铀产品的杂质含量,发现对产品质量几乎无影响。Base on calculation and under considering the cumulative effect of impurities,20% of extraction raffinate can be recycled without influence of product quality of uranium dioxide;and the water brought into production system by the recycle of 20% of extraction raffinate is acceptable in the production process.During the period of recycling extraction raffinate,the content of impurities in uranium oxide product was tracked and analyzed each month.The results show that the quality of the product was not affected.
