ELECTRICAL EQUIPMENT REVIEW RESPONSIBILITIES Primary - Organization responsible for mechanical engineering reviews Secondary - Organization responsible for reviews of electrical engineering and instrumentation and controls I. AREAS OF REVIEW The applicant’s safety analysis report (SAR) should contain information concerning the methods of test and analysis employed to ensure the functionality of mechanical and electrical equipment (includes instrumentation and controls) under the full range of normal and accident loadings (including seismic). The SAR is reviewed to ensure conformance with the requirements of 10 CFR Part 50, Appendix A, General Design Criteria (GDC) 1, 2, 4, 14, and 30; 10 CFR Part 50, Appendix B; and 10 CFR Part 50, Appendix S. Mechanical and electrical equipment must be designed to withstand the effects of earthquakes (i.e., Seismic Category I requirements and other accident-related loadings). Mechanical and electrical equipment covered by this Standard Review Plan (SRP) section includes equipment associated with systems that are essential to emergency reactor shutdown, containment isolation, reactor core cooling, and containment and reactor heat removal or are otherwise essential in preventing significant release of radioactive material to the environment. Also covered by this SRP section is equipment (1) that performs the above functions automatically, (2) that is used by the operators to perform these functions manually, and (3) whose failure can prevent the satisfactory accomplishment of one or more of the above safety functions. This SRP section also covers instrumentation that is needed to assess plant and environs conditions during and after an accident, as described in Regulatory Guide (RG) 1.97. Examples of mechanical equipment included in these systems are pumps, valves, fans, valve operators, and snubbers. Examples of electrical equipment are battery and battery racks, instrument and instrument racks, control consoles, electrical
