What is the primary function of the main condenser?

The primary function of the main condenser is to convert steam back to water. This process is essential in a steam power system, such as that found in naval reactors, where steam generated in the reactor is used to turn turbines and produce electricity or propulsion. Once the steam has performed its work, it must be condensed back into liquid water in order to be reused in the cycle.

The condenser typically operates by using seawater or another cooling medium to remove heat from the steam. This heat exchange causes the steam to cool and condense back into water, which is then returned to the steam generator or reactor to be heated again. This closed-loop system is crucial for maintaining efficiency and ensuring a continuous supply of steam for power generation.

In contrast, other functions like heating water for the reactor, increasing steam pressure, or cooling reactor coolant do not directly describe the condenser's role in the steam cycle. These functions relate to different components in the system, such as heaters or sub-systems dedicated to reactor control and safety.
