omatically, (2) that is used by the operators to perform these above 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, “Criteria for Accident Monitoring Instrumentation for Nuclear Power Plants.” 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 cabinets, electrical panels, 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 Sections 3.7.2 and 3.7.3, for reviewing the licensee’s analysis of seismic and dynamic input motion for all pipe- mounted equipment. In addition, the primary review organization is responsible, in accordance with SRP Section 3.2.1, for reviewing the seismic classification of systems that perform the functions delineated in the previous paragraph. The secondary review organizations, in fulfilling their secondary review responsibility, verify 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. Qualification criteria are the criteria for
