Abstract

This report describes the research results on Electromagnetic Compatibility technologies for I&C(Instrumentation and Control) systems for nuclear power plants. As the nuclear industries are adopting the digital equipment rather than the conventional analog type equipment for safety I&C systems as well as non-safety systems of nuclear power plants(NPPs), it is necessary to secure compatibility against EMI(e1ectromagnetic interference) for the digital safety I&C systems.

EM1 qualification, identified as a regulatory compliance item by US NRC and Korean regulatory body, should be performed in accordance with appropriate standards, because the electromagnetic environment is regarded as one of the environmental factors possible to affect the safety functions. As a technical guide on this EM1 issue, this report includes description of code and starldards scheme, EM1 qualification methods, noise reduction strategies, and survey on noise levels in nuclear power plants.
