An electric power substation is a facility that provides a junction between parts of the power grid. The substation s functions, critical for the proper operation of the power system, include the interconnection of power lines from different parts of the system the monitoring and control of system operating conditions and the protection of the power system equipment. 

Because the engineered safety features are passive systems or are actuated by the protection and safety monitoring system (with diverse actuation system (DAS) backup), whereas the plant duty systems are electrically powered and actuated by the plant control system (PLS), there is significant diversity between the duty and protection systems. 

System for control, protection or monitoring based on one or more electrical/electronic programmable electronic (E/E/PE) devices, including all elements of the system such as power supplies, sensors and other input devices, data highways and other commimication paths, and actuators and other output devices. 

The four divisions (guard lines) of the protection and safety monitoring system and its uninterruptible power supply, the electrical penetrations through the containment, portions of the plant control system, the main control room and the remote shutdown workstation are concentrated within the northern section of the Auxiliary Building. A large fire or explosion in this area could render these features imusable for a significant amount of time. Such an event would most likely result in an immediate reactor trip, due to the loss of power and control...
