ides a technical basis for the control of upsets and malfunctions in safety-related I&C systems caused by EMI/RFI and power surges (Ref. 5). • NUREG/CR-6431, “Recommended Electromagnetic Operating Envelopes for Safety- Related I&C Systems in Nuclear Power Plants,” contains recommendations for electromagnetic operating envelopes to augment test criteria and test methods addressing EMI, RFI, and power surges that are applicable to safety-related I&C systems in nuclear power plants (Ref. 6). • NUREG/CR-5609, “Electromagnetic Compatibility Testing for Conducted Susceptibility Along Interconnecting Signal Lines,” contains recommendations and a supporting technical basis for addressing the effects of conducted EMI and RFI along interconnecting signal lines in safety-related I&C systems (Ref. 7). • NUREG/CR-6782, “Comparison of U.S. Military and International Electromagnetic Compatibility Guidance,” reports the results of a study performed by the ORNL staff comparing RG 1.180, the U.S. military standards, and international EMC guidance (Ref. 8). DG-1333, Page 3 • RG 1.89, “Environmental Qualification of Certain Electric Equipment Important to Safety for Nuclear Power Plants” (Ref. 9), describes an acceptable method for demonstrating environmental qualification for safety-related electric equipment. • RG 1.204, “Guidelines for Lightning Protection of Nuclear Power Plants” (Ref. 10), describes an acceptable method for establishing lightning protection at nuclear power facilities, which contributes to controlling the lightning-induced surge environment. • RG 1.209, “Guidelines for Environmental Qualification of Safety-Related Computer-Based Instrumentation and Control Systems in Nuclear Power Plants” (Ref. 11), describes an acceptable method for demonstrating environmental qualification for digital I&C systems, which addresses service conditions that include electromagnetic and power surge environments.
