Abstract

Abstract

Electromagnetic interference (EMI) has a significant impact on the I&C equipment of nuclear power plants. In some nuclear power plants, EMI leads to false alarm of protection equipment, misoperation or refusal to operate of protection system, resulting in false shutdown and even reactor shutdown accident. Therefore, it is necessary to make targeted solutions for each interference source of EMI. Taking the interference of temperature measuring elements in a nuclear power plant as an example, this paper uses the method of layer by layer evolution to find out the interference source, analyze the interference characteristics, and finally propose a solution. Measures such as improving the grounding of important protection signals, and issuing the regulations on EMI prevention management of operating units have greatly reduced the impact of EMI on operating equipment in nuclear power plants.
