摘　　要：岭澳核电站从第二循环开始采用新的AFA-3G燃料组件,并从第三循环开始提高燃料235U的富集度。因此,大亚湾核电运营管理有限责任公司于2001年开始进行岭澳混合堆芯项目的论证。本文用SCIENCE、ESPADON、CINEMA、CANTAL、FLICA等分析工具对混合堆芯提高燃料富集度的落棒事故进行了分析。分析结果表明,在落棒事故条件下的最小DNBR值满足设计限值。AFA 2G assemblies in Ling’ao nuclear power station were replaced gradually by AFA 3G assemblies from cycle 2 and subsequent cycles.The enrichment of the fuels was increased from 3.2% to 3.7% from cycle 3 in Ling’ao.Therefore,the study of Ling’ao mixed core and increased enrichment was launched in 2001.Rod drop accident for Ling’ao Nuclear Power Station was re-analyzed in the frame of Framatome ANP analytical methodology.The analytical codes used in the accident analysis includes SCIENCE,ESPADON,CINEMA,CANTA...
