摘　　要：针对超临界水冷堆组件,采用不同Pu含量的MOX燃料进行组件计算,得到不同燃料条件下的燃耗深度、功率分布因子、慢化剂温度反应性系数等结果,并对比分析在超临界水冷堆中应用MOX燃料与应用UO2燃料对组件性能的影响,以及不同Pu含量MOX燃料间的性能区别。分析结果表明,在超临界水冷堆设计中,应用MOX燃料与应用UO2燃料有相似的功率分布,应用MOX燃料可以增加燃耗深度,并有良好的慢化剂温度反应性系数。经过合理设计的MOX燃料可较好应用于超临界水冷堆中,且产生更好的性能。Making use of MOX fuel which is made up of different compositions, a calculation was made for supercritical water cooled reactor （SCWR）. Taking account of fuel burnup, power distribution factor, temperature reactivity coefficient, a analysis was made for using UO2 fuel and MOX fuel in SCWR and using different MOX fuels in SCWR. The results indicate that MOX fuel has a simple power distribution with UO2 fuel, and has better fuel burnup, reactivity coefficient than UO2 fuel in SCWR. MOX fuel may apply in SCWR with reasonable design, and has a better property.
