摘要
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 purpose of our work is to find a way for application of depleted uranium inCANDU reactor by using MOX nuclear fuel of depleted U and Pu instead of naturaIuranium. From preliminary evaluation and calculation, it was shown that MOXnuclear fuel consisting of depleted uranium enrichment tailings (0.25% 235U) andplutonium (their ratio 99.5%:0.5%) could replace natural uranium in CANDU reactorto sustain chain reaction. The prospects of application of depleted uranium in nuclearenergy field are also discussed.
