REVIEW RESPONSIBILITIES Primary - Equipment Qualification Branch (EQB) Secondary - None 1. AREAS OF REVIEW Information concerning the methods of test and analysis employed to assure the oper- ability 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 EQB to assure 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 acctdent-related loadings. Mechanical and electrical equipment covered by this SRP section includes equipment associated with systems that are essential to emergency reactor shutdown, contain- ment 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. Examples of mechanical equipment included in these systems are pumps, valves, fans, valve operators, battery and instrument racks, control consoles, cabinets, and panels. Examples of electrical equipment are valve operator motors; solenoid valves, pressure switches, level transmitters, electrical penetrations, and pump and fan motors. At the construction permit (CP) stage, the staff review covers the following spe- cific areas: Rev. 2 - July 1981 USNRC STANDARD REVIEW PLAN Standard review plans are prepored for the ide of the offico of Nuclear
