What is the function of MMR in a ship's reactor?

The function of the Main Machinery Room (MMR) in a ship's reactor is fundamentally related to the generation and management of power and steam. The MMR is responsible for utilizing the ship's steam not only for propulsion but also for power generation and the production of fresh water. This is essential for the overall operation of the ship, as steam generated in the reactor can drive turbines that propel the ship through the water, generate electrical power to support onboard systems, and can also be used in desalination processes to produce potable water for the crew.

Proper operation of the MMR is crucial for efficiency and sustainability during a voyage, as it ensures that the ship maintains the necessary operational capabilities, including propulsion and power for various systems, while also addressing the crew's basic needs for water. Understanding the role of the MMR is vital for anyone working in or studying naval engineering and operations.
