Where are the CACs located in the Reactor Auxiliary Room?

The correct answer is that there is one CAC (Component Auxiliary Controller) in each Reactor Auxiliary Room (RAR) and Main Machinery Room (MMR). This arrangement is essential for effective monitoring and control of the plant systems, as the CACs are critical components for maintaining the operational integrity of the ship’s reactor plant. Having one in each location ensures that operators have direct access to controls and monitoring capabilities pertinent to both the reactor and associated machinery, allowing for efficient responses to any operational changes or emergencies.

This distribution enhances redundancy and allows for localized control, which is vital for operational safety and efficiency. By having CACs in both the RAR and MMR, the ship can maintain crucial systems without the need to rely solely on a centralized control room or a single point of failure, thus enhancing overall operational reliability.
