A reactor protection system (RPS) is a set of nuclear safety components in a nuclear power plant designed to safely shutdown the reactor and prevent the release of radioactive materials. The System can "trip" automatically (initiating a scram), or it can be tripped by the operators. Trips occurs when the parameters meet or exceed the limit setpoint. A trip of the RPS results in full insertion (by gravity in pressurized water reactors or high-speed injection in boiling water reactors) of all control rods and shutdown of the reactor.
