摘要
控制棒驱动机构为核反应堆系统中的重要设备,是一回路压力边界组成部分,起到调节反应堆功率、实现正常停堆和事故工况下紧急停堆的功能。本文介绍了CPR1000、AP1000和EPR控制棒驱动机构在设计参数、结构、材料选用等方面的差异,并分析了这些差异对控制棒驱动机构安全性能的影响。
Control rod drive mechanism is the important equipment in nuclear reactor system of pressurized water reactor and the part of first loop pressure boundary components, which fulfills the function of adjusting power, shutdowns reactor in general conditions and emergency shutdowns reactor in accident conditions. The article introduces the difference among CPR1000,AP1000 and EPR control rod drive mechanism about design parameter, structure and material election etc, and analyzes the impact of the differences on safety of control rod drive mechanism.
