摘要
在堆芯发生较大的升降功率后，往往会出现修正硼浓度突降，导致硼浓度变化偏离原有预期曲线。本文结合秦山二期1号机组第五燃料循环停堆缺陷处理前后的硼浓度突降数据，讨论了产生这种现象的主要原因，并结合跟踪数据进行了量化分析。
After great core power level ascension or descension, the corrected boron concentration often reduces suddenly, and the boron concentration change trends to deviate from the anticipated curve. This thesis analyzed the boron concentration data before and after Qingshan phase two U1C5 failure mend, discuss the cause of this kind of phenomena and made a quantitative analysis.
