Reactor protection system

The reactor protection system is a self-monitoring, automatic device in nuclear power plants that initiates a reactor shutdown in the event of operational deviations.

The reactor protection system continuously collects information such as pressures, temperatures, voltages and operating states from the plant and interprets it. If it detects irregularities, it moves the control rods into the reactor core without any action on the part of the operating team, and the chain reaction automatically comes to a standstill.
