Analysis of Boron Acid Concentration Drop during Power Changing Process
-
摘要: 硼浓度对反应堆机组的安全稳定运行起着至关重要的作用。从反应性平衡的角度对硼浓度"突降"现象进行了分析和解释。结果表明,毒物的动态变化是影响硼浓度运行偏离理论计算的主要因素。此分析结果对在役核电厂反应堆运行期间的硼浓度运行有很好的借鉴和指导作用。Abstract: Boron acid is very important to the control of the nuclear power station. The boron acid concentration drop has been analyzed and explained by using the reactivity balance formula. The conclusion is that the dynamic poison is the main reason. This paper is a good reference and guideline for the boron acid concentration management in the nuclear power station.
