由于国内核电厂控制棒运行经验少,且没有控制棒更换的相关法规或标准,为掌握控制棒包壳管状态,秦山第二核电厂通过超声、涡流等无损检测方法对在役的控制棒包壳进行了检查,得到控制棒运行可靠的技术数据,为调整和更换控制棒组件提供依据。本文通过控制棒组件典型缺陷机理分析与评价,提出了核电厂控制棒优化管理的几项措施,可以为其他核电厂控制棒管理提供重要的参考与借鉴。 Due to the lack of operational experience of the control rods of nuclear power plants in China and the lack of relevant regulations or standards for control rod replacement, in order to grasp the status of the control rod cladding tubes, the Qinshan No.2 Nuclear Power Plant, through nondestructive testing methods such as ultrasonic and eddy current, The shell was inspected to obtain reliable technical data for control rod operation, providing a basis for adjusting and replacing the control rod assembly. Based on the analysis and evaluation of the typical defect mechanism of control rod assembly, this paper proposes several measures to optimize the control rod design of nuclear power plant, which can provide important reference for the control rod management of other nuclear power plants.
