ELECTRICAL EQUIPMENT REVIEW RESPONSIBILITIES Primary - Equipment Qualification Branch (EQB)Mechanical Engineering Branch (EMEB)1 Secondary - noneInstrumentation and Controls Branch (HICB)2 I. AREAS OF REVIEW Information concerning the methods of test and analysis employed to assureensure the 3 operability of mechanical and electrical equipment (includes instrumentation and control) under the full range of normal and accident loadings (including seismic) should be provided in the applicant's safety analysis report (SAR) and is reviewed by the EQBEMEB to assureensure 4 5 conformance with the requirements of General Design Criteria 1, 2, 4, 14, and 30 of Appendix A to 10 CFR Part 50, as well as Appendix B to 10 CFR Part 50 and Appendix A to 10 CFR Part 100. 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 6 includes equipment associated with systems that are essential to emergency reactor shutdown, containment isolation, reactor core cooling, and containment and reactor heat removal, or otherwise are 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. Instrumentation that is needed to assess plant and environs conditions during and after an accident, as described in Regulatory Guide 1.97, is also covered by this DRAFT Rev. 3 - April 1996 3.10-2 SRP section. Examples of mechanical equipment included in these systems are pumps, valves, 7 fans, valve operators, snubbers, battery and instrument racks, control consoles, cabinets, and 8 panels. Examples of
