Core Components of Nuclear Propulsion Systems in Naval Ships
The core components of nuclear propulsion systems in naval ships include several specialized elements designed to harness and sustain nuclear energy for propulsion. The primary components are the reactor, the coolant system, and the power conversion equipment.
The reactor core contains nuclear fuel, typically uranium or plutonium, where nuclear fission occurs. This process produces immense heat, which is transferred through the coolant—a substance such as pressurized water or liquid metal—to prevent the core from overheating.
The coolant system circulates the heat away from the reactor core to the steam generators or turbines. These turbines convert thermal energy into mechanical energy, which ultimately drives the ship’s propeller shafts. The power conversion component involves the use of electrical generators to supply energy for onboard systems.
Key components include:
- Reactor core with nuclear fuel assemblies;
- Coolant loops and heat exchangers;
