对以贫铀和钚组成MOX核燃料替代CANDU堆中的天然铀的可能性进行了探讨，从而开辟贫铀用于核能的途径。经过初步验算，得出了用235U含量为0.25％的贫化铀浓缩残渣和钚组成MOX核燃料（其重量比为99．5：0．5）可以替代CANDU堆中的天然铀来维持重水堆中的链式反应，达到核能利用的目的。并展望了贫铀应用的前景。
The possibility of substituting depleted uranium and plutonium for MOX nuclear fuel for natural uranium in the CANDU reactor was explored in order to open up ways for depleted uranium to be used in nuclear energy. After a preliminary examination, it was concluded that MOX nuclear fuel (99.5: 0.5 by weight) can be used to replace natural uranium in the CANDU reactor to maintain the heavy water reactor in a 0.25U depleted uranium enrichment residue and plutonium Chain reaction, to achieve the purpose of nuclear energy use. The prospect of depleted uranium application is also forecasted.
