压水堆核电站控制棒位置测量准确性因素研究

The Study on Influencing Factors of Control Rod Position Measurement Accuracy in PWR Nuclear Power Station

压水堆核电站的控制棒棒位系统主要是显示控制棒在反应堆内的位置,通过位置的给定来控制反应堆的功率。论文主要通过分析影响压水堆棒位测量精度的主要影响因素,总结了该类棒位探测器的设计特点和固有缺陷。同时针对一些固有缺陷,初步提出改进的方法。

The rod position system of pressurized - water reactor nuclear power station primarily displays the positions of control rods in the reactor. The article summarizes the design characters and objections of this detector through analyzing the influence factors on measurement precision of rod position. At the same time, some improvements to the system are presented according to these objections.
