d 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 cabinets, electrical panels, 3.10-2 Revision 3 - March 2007 valve operator motors, solenoid valves, pressure switches, relays, level transmitters, electrical penetrations, and pump and fan motors. The primary review organization has the responsibility, in accordance with SRP Section 3.9.2, for defining the seismic and dynamic input motion for all pipe-mounted equipment. In addition, the primary review organization is responsible, in accordance with SRP Section 3.2.2, for defining the systems that perform the functions delineated in the previous paragraph. The secondary review organizations, in fulfilling their secondary review responsibility, verifies that electrical equipment and instrumentation and controls for the equipment described in the previous paragraphs, as well as for Category 1 accident monitoring instrumentation as defined in Revision 2 and 3 of RG 1.97 and Type A, B, C, and D accident monitoring instrumentation as defined in Revision 4 of RG 1.97, are included in the seismic and dynamic qualification program and that the performance aspects of these items are included in the seismic and dynamic qualification testing. The specific areas of review are as follows: 1. Qualification Criteria. The criteria for qualification, such as the deciding factors for choosing between tests or analyses, the considerations in defining the seismic and other relevant dynamic load input motions, and the demonstration of adequacy of the qualification program. 2. Structural Integrity and Functionality of Mechanical and Electrical Equipment. The methods and procedures, including tests and analyses, used to ensure structural integrity and the functionality of mechanical and electrical equipment in the event of a safe-shutdown earthquake (SSE), after a number of postulated
