摘　　要：在压水堆核电站中,通过改变一回路冷却剂的硼浓度来控制和补偿堆芯的反应性,同时使堆芯功率分布尽可能展平,以达到增加燃耗深度的目的。硼表对一回路硼浓度的实时在线监测,对核电站的安全、经济运行起到了重要的作用。通过硼表运行过程中的周期性波动,分析了电磁干扰对硼表运行的影响。In PWR nuclear power plants,core reactivity is controlled and compensated by changing boron concentration in primary coolant,and core power distribution is flattened as much as possible to increase burnup depth.Therefore boron meters,by real-time online monitoring primary coolant's boron concentration,are of great significance to safe and economic operation of nuclear plants.This paper analyzes the influence of electromagnetic interference on boron meters through the periodic fluctuation during their working process.
