【摘要】 依赖于专家知识建立了大亚湾核电站和秦山第二核电厂换料堆芯装载知识库,在此基础上进行换料堆芯装载方案启发式优化搜索。应用已用于工程设计的二维细网堆芯燃料管理程序系统(INCORE)进行装载方案评价,采用循环长度和堆芯功率峰因子综合指标计算装载方案的价值并评价其优劣程度。用该系统分别对大亚湾核电站二号堆第四循环和秦山第二核电厂第四循环堆芯优化方案搜索计算。结果表明,无论从堆芯径向功率峰因子还是从循环长度指标来看,专家系统SEDRIO/INCORE搜索得到的装载方案都明显优于参考方案。更多还原

【Abstract】 The expert knowledge library for Daya Bay and Qinshan phase II NPP has been established based on expert knowledge, and the reload core loading pattern heuristic search is performed with this li-brary. The in-core fuel management code system INCORE that has been used in engineering design is em-ployed for neutron calculation, and loading pattern is evaluated by using of cycle length and core radial power peaking factor. The developed system SEDRIO/INCORE has been applied in cycle 4 for unit 2 of Daya Bay NPP and cycle 4 for Phase II in Qinshan NPP. The application demonstrated that the loading patterns obtained by SEDRIO/INCORE system are much better than reference ones from the view of the radial power peak and the cycle length.更多还原
