| 摘 要： | 针对HPR1000压水堆堆芯,开展了应用MOX(混合氧化物燃料)组件的燃料管理方案初步研究。对MOX燃料组件进行设计,研究了MOX燃料成分及燃料棒在组件内的布置。在此基础上,开展了1/4堆芯年换料、18个月长周期换料,并装载50%MOX组件这两种燃料管理方案研究。通过与UO2堆芯的对比,分析了装载50%MOX组件堆芯的核特性。分析结果表明,两种50%堆芯装载MOX组件的燃料管理方案,其堆芯主要物理参数均满足核设计准则要求。

| Abstract: | Fuel loading pattern optimization with MOX (mixed oxide of plutonium and uranium) fuel is an important aspect for GIII LWR. For the HPR1000 core, an optimized MOX fuel is designed. Based on which, two loading patterns with 50% MOX fuel are designed. One is 1/4 core annually reloading pattern, and the other is 18-month reloading pattern. The core neutronic parameters are investigated by comparing with the 100% UO2 core. The MOX fuel has impacts on the nuclear characteristic parameters, but the 50% MOX core still satisfies the nuclear and safety criteria samilar to that considered in 100% UO2 core. The results of this study prove that the GIII LWR HPR1000 has excellent capability while loading with 50% MOX fuel. |
