The correct answer is pressurized water reactor (PWR), which is widely utilized in naval operations, particularly in submarines and aircraft carriers. PWRs are effective because they use water under high pressure as both a coolant and neutron moderator, allowing the water to remain liquid and efficiently transfer heat to produce steam for propulsion while preventing it from boiling.

The design of PWRs offers several advantages for military applications, including compact size and the ability to operate at high temperatures and pressure, which is crucial for delivering sustained power in a naval environment. PWR systems also have a proven operational history and are known for their safety and reliability, making them a common choice for the propulsion reactors of naval vessels. Additionally, the steam produced in a PWR can be directly used to drive turbines for propulsion or generate electricity, enhancing the operational capabilities of the ship.

Other types of reactors, like boiling water reactors (BWRs) and gas-cooled reactors (GCRs), have different methods of generating steam or cooling and are less commonly used in naval applications. Fast breeder reactors (FBRs), while capable of producing more fuel than they consume, are not a standard choice for surface vessels primarily due to their complexity and specific operational requirements that do not align
