- 1. Compare electrical schematics and logic diagrams for the reador protection system, emergency diesel generator load shedding and sequencing, and actuation logic for the engineered safety feature systems against plant surveillance test procedures to ensure that all portions of the logic circuitry, including the parallel logic, interlocks, bypasses, and inhibit circuits, are adequately covered in the surveillance procedures to fulfill the technical 0
specification requirements. ' This review should also include relay contacts, control switches, I
and other relevant electrical components within these systems, utilized in t.)e logic circuits performing a safety function; and
