摘要

With nuclear plants starting to modify critical components that support plant operations,rnElectromagnetic Compatibility (EMC) is a key factor in determining what equipment can be designed,rnpurchased, and installed. But when the first round of testing fails for the automatic voltage regulatorsrn(AVRs) that support the emergency diesel generators at Palo Verde, the nation’s largest nuclear powerrnplant, how does the design team provide station management with the confidence to proceed with arnmodification on this obsolete/aging equipment?rnThis paper will discuss the multi-tiered approach to identifying the specific emission and susceptibilityrncharacteristics for the existing AVRs by performing plant mapping, mimicking the physical plantrnlayout for the EMC qualification testing, hardening the equipment against internal and externalrninterference, and aligning with industry standards and guidelines in order to meet the EMCrnrequirements for safety-related equipment for nuclear power plants. As a result of this approach, andrnworking 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 forrninstallation in the near future.rnThis discussion highlights several additional avenues for addressing more complicated EMC issues forrnimportant structures, systems, and components in nuclear facilities while also providing the stationrnwith the confidence to precede with potential high-risk design changes using these relatively newrntesting requirements.
