This study examines the feasibility of relaxing the reactor protection system (RPS) trip setpoints of Combustion Engineering (C-E) pressurized water reactors so that unnecessary scrams may be avoided. Unnecessary scrams are those that are not required to protect fuel integrity, plant equipment, or public health and safety. They result in lost generating capacity, pose unnecessary challenges to plant equipment, and are an operational nuisance. With relaxed trip setpoints, unnecessary scrams would be avoided by allowing greater operational flexibility. This scram reduction study was sponsored by the Nuclear Safety Analysis Center of the Electric Power Research Institute. The scram reduction program was separated into two parts. In the first part, C-E reactors with analog RPS's were examined. In the second part, the reactors with digital systems were studied.
