摘　　要：为优化M310机组现行技术要求的在升功率达到指定功率水平后等待24 h再实施堆芯测量试验的时间,进一步提升压水堆核电厂的经济性,本文基于西安交通大学自主研发的先进压水堆堆芯物理分析软件Bamboo-C,研发了动态氙条件下实施堆芯通量测量的新方法。通过动态氙通量测量数据预测平衡氙条件下堆芯功率分布实测值,并在田湾核电站5号机大修中进行了工程应用验证。验证结果表明,本文提出的动态氙通量测量方法可以将指定功率水平下的氙平衡等待时间缩短至2 h,且对堆芯关键物理量具有很高的预测精度。In order to optimize the current technical requirements of M310 unit,i.e.to wait for 24 h after the power increases to the specified power level to perform in-core flux measurement test,so as to further improve the economy of PWR nuclear power plant,a new method for core flux measurement under dynamic xenon conditions is developed based on Bamboo-C,an advanced PWR core physical analysis software independently developed by Xi'an Jiaotong University.Based on the dynamic xenon flux measurement data,the measured values of core power distribution under the condition of balanced xenon were predicted,and the engineering application was verified in the overhaul of Tianwan No.5 unit.The verification results show that the dynamic xenon flux measurement method proposed in this paper can shorten the waiting time of xenon balance to 2 h at a specified power level,and has high prediction accuracy for key physical quantities in the core.
