摘要

With nuclear plants starting to modify critical components that support plant operations, Electromagnetic Compatibility (EMC) is a key factor in determining what equipment can be designed, purchased, and installed. But when the first round of testing fails for the automatic voltage regulators (AVRs) that support the emergency diesel generators at Palo Verde, the nation’s largest nuclear power plant, how does the design team provide station management with the confidence to proceed with a modification on this obsolete/aging equipment? This paper will discuss the multi-tiered approach to identifying the specific emission and susceptibility characteristics for the existing AVRs by performing plant mapping, mimicking the physical plant layout for the EMC qualification testing, hardening the equipment against internal and external interference, and aligning with industry standards and guidelines in order to meet the EMC requirements for safety-related equipment for nuclear power plants. As a result of this approach, and working closely with industry peers in the development of the mapping, testing, and design of the new AVRs the equipment successfully passed the full range of EMI/RFI testing and will be ready for installation in the near future. This discussion highlights several additional avenues for addressing more complicated EMC issues for important structures, systems, and components in nuclear facilities while also providing the station with the confidence to precede with potential high-risk design changes using these relatively new testing requirements.
