What is the primary function of the CACs in the reactor plant?

The primary function of the Component Auxiliary Cooling System (CACs) in the reactor plant is to provide air for pilot-operated valves. These valves are essential in the operation of various systems within the reactor plant, as they control the flow of fluids and gases necessary for efficient and safe reactor operation. The CACs ensure that the pilot-operated valves receive the necessary air pressure to function correctly, facilitating the control of critical components within the reactor plant.

This function is crucial for maintaining operational integrity, ensuring that the reactor systems can respond appropriately to operational demands and safety protocols. Without this function, the reliability of the systems that depend on pilot-operated valves would be compromised, potentially impacting the overall safety and efficiency of the reactor plant.
