emergency diesel generator load shedding and sequencing, and actuation logic for the fi engineered safety feature systems against plant surveillance test procedures to ensure i 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 specification requirements. This review should also include relay contacts, ]

control switches, and other relevant electrical components within these systems, utilized I in the logic circuits performing a safety function; and I
