Page 2 assurance criteria also apply to nuclear power reactor licenses issued under 10 CFR Part 52, “Licenses, Certifications, and Approvals for Nuclear Power Plants” (Ref. 3). Related Guidance In revision 1 of RG 1.89, “Environmental Qualification of Certain Electric Equipment Important to Safety for Nuclear Power Plants,” (Ref. 4) the NRC staff endorsed, in part, Institute of Electrical and Electronics Engineers (IEEE) Standard (Std.) 323-1974, “IEEE Standard for Qualifying Class 1E Equipment for Nuclear Power Generating Stations,” (Ref. 5) which is generally used by the nuclear industry to qualify safety-related (Class 1E) electric equipment located in an environment resulting from a postulated DBE (termed a harsh environment in IEEE Std. 323-2003, “IEEE Standard for Qualifying Class 1E Equipment for Nuclear Power Generating Stations,” (Ref. 6)), non-safety related equipment whose failure under postulated environmental conditions could prevent satisfactory accomplishment of certain safety functions, and certain post-accident monitoring equipment needed to satisfy the requirements in 10 CFR 50.49, “Environmental Qualification of Electric Equipment Important to Safety for Nuclear Power Plants.” In RG 1.100, “Seismic Qualification of Electrical and Active Mechanical Equipment and Functional Qualification of Active Mechanical Equipment for Nuclear Power Plants,” (Ref. 7) the NRC staff describes methods considered acceptable for the seismic qualification of electrical and active mechanical equipment and the functional qualification of active mechanical equipment for nuclear power plants. In revision 3 of RG 1.100, the NRC staff endorses the use of IEEE Std. 344-2004, “Recommended Practice for Seismic Qualification of Class 1E Equipment for Nuclear Power Generating Stations,” (Ref. 8) and the American Society of Mechanical Engineers (ASME) Standard QME-1-2007, “Qualification of Active Mechanical Equipment Used in Nuclear Power Plant,”
