摘　　要：随着科技的不断发展,越来越多的精密仪器被应用于核电站,尤其是5G技术的使用。这对辐射抗扰度提出了更高要求。为规范核电仪控设备辐射抗扰度试验程序,通过对比分析相应标准,以及核电站现场电磁环境检测经验,对辐射抗扰度试验的不同配置情况进行了差异性分析。针对不同的试验场景,给出了相应试验方案的建议。对于某些特殊设备,创新性地通过简化设备在电场中的模型,再通过理论计算出电场对设备的影响量,并结合实际情况给出了相应的试验整改方案。该研究为仪控设备的辐射抗扰度试验方案及程序提供指导。针对试验中可能出现的问题,从理论层面给出了对应的整改对策,为实现智慧核电的目标提供了有力支撑。With the continuous development of science and technology,more and more precision instruments are applied to nuclear power plants,especially the use of 5G technology.This puts forward higher requirements on radiation immunity.To standardize the radiation immunity test procedure of nuclear power instrumentation and control equipment,different configurations of radiation immunity test are analyzed by comparing and analyzing the corresponding standards and the experience of electromagnetic environment testing in nuclear power plants.For different test scenarios,suggestions for corresponding test programs are given.For some special equipment,the model of the equipment in the electric field is simplified innovatively,and then the amount of influence of the electric field on the equipment is calculated theoretically,and the corresponding test rectification plan is given in combination with the actual situation.The research provides guidance for the radiation immunity test program and procedure of instrumentation and control equipment.Corresponding rectification countermeasures are given from the theoretical level for the problems that may arise in the test,which provides strong support for realizing the goal of intelligent nuclear power.
