摘　　要：介绍了国内在建核电厂仪控设备接地与屏蔽的设计,尤其是三代非能动核电项目中接地方案的实施情况。与传统仪控设备接地的设计进行了比较,重点分析了电缆屏蔽层双端通过设备外壳接地的运用,对今后新建核电项目的仪控设备接地与屏蔽方案提出了建议。The instrumentation and control （I＆C） equipments grounding and shielding methods and implementation in domestic 3rd-generation nuclear power plant （NPP） project are reviewed first. Compared to traditional I＆C grounding methods, the shielded circuit grounded at both ends design is described in detail. Finally, a general grounding and shielding solution for I＆C equipments that will be applied for the new nuclear power plant projects is proposed.
