堆芯功率能力分析是在确定的反应堆运行模式下研究堆芯功率分布的控制,以满足核电厂在Ⅰ类工况下电厂机动性要求和Ⅱ类工况时安全性要求。传统的功率能力分析方法,比如综合法或较为先进的三维分析方法,均是计算功率分布相应的关键安全参数,并验证关键安全参数满足相应的设计准则。对于使用在线功率分布监测系统的压水堆,功率能力分析方法计算满足设计准则的最大功率水平。以西屋3D FAC 方法为基础,给出裕量法功率能力的计算模型;并采用裕量法进行三门核电厂首循环特定燃耗步的功率能力分析,证明裕量法计算模型的合理性。裕量法计算模型不仅有助于工程设计人员快速掌握 AP1000核电厂的功率能力分析方法;同时也为其他具有堆内监测系统的反应堆的堆芯功率能力分析提供参考。

Core power capability analysis focuses on the power distribution control of reactor within the given mode of operation,for the purpose of defining the allowed normal operating space so that Condition I maneuvering flexibility is maintained and Condition II occurrences are adequately protected by the reactor protection system. For the traditional core power capability analysis methods,such as synthesis method or advanced three dimension method,usually calculate the key safety parameters of the power distribution,and then verify that these parameters meet the design criteria. For PWR with on-line power distribution monitoring system,core power capability analysis calculates the most power level which just meets the design criteria. On the base of 3D FAC method of Westinghouse,the calculation model of core power capability analysis with margin method is introduced to provide reference for engineers. The core power
<br> capability analysis of specific burnup of Sanmen NPP is performed with the margin method. The results demonstrate the rationality of the margin method. The calculation model of the margin method not only helps engineers to master the core power capability analysis for AP1000,but also provides reference for engineers for core power capability analysis of other PWR with on-line power distribution monitoring system.
