What is maintained by the Main Air Ejectors in the reactor system?

• A. Vacuum in main condensers
• B. Pressure in the steam lines
• C. Temperature in the reactor core
• D. Level in the cooling tanks

Answer: (A)

The Main Air Ejectors play a crucial role in maintaining a vacuum in the main condensers of the reactor system. By creating a vacuum, the ejectors ensure that steam from the reactor and turbine can flow efficiently into the condensers, allowing for effective heat exchange and condensation of steam back into water. This process is vital for the overall efficiency of the steam propulsion cycle, as a strong vacuum reduces the pressure, which helps to enhance the thermodynamic efficiency of the system. Additionally, maintaining a vacuum in the condensers prevents air and non-condensable gases from entering the system, which could interfere with heat transfer and reduce thermal efficiency. This functional aspect of the Main Air Ejectors is integral to the proper operation of the reactor system.
