Nuclear marine propulsion is propulsion of a ship or submarine with heat provided by a nuclear reactor. The power plant heats water to produce steam for a turbine used to turn the ship's propeller through a gearbox or through an electric generator and motor.
Bimodal nuclear thermal rockets conduct nuclear fission reactions similar to those employed at nuclear power plants including submarines. The energy is used to heat the liquid hydrogen propellant. The vehicle depicted is the "Copernicus" an upper stage assembly being designed for the Space Launch System (2010).
This naval nuclear reactor is estimated to generate 210 megawatts (MWt) [3] driving a 30 MW pump-jet propulsion system built by BAE Systems that was designed for the Royal Navy [4] and entered service on the second Trafalgar-class submarine, also featured on the Astute-class submarines.
China's nuclear submarine fleet has grown rapidly to more than a dozen boats, ... with a new propulsion system, improved electronics and sensors, and, perhaps most crucially, lower sound levels. ...
A nuclear submarine is a submarine powered by a nuclear reactor, but not necessarily nuclear-armed.In the US classification, nuclear-powered submarines are designated as SSxN, where the SS denotes submarine, x=G means that the submarine is equipped with guided missiles (usually cruise missiles), x=B means that the submarine is equipped with ballistic missiles (usually intercontinental) and the ...
[44] [45] It will retain the nuclear reactor and steam turbines typical of U.S. Navy submarines. In such systems, the nuclear reactor heats water to steam, the turbines convert the heat in the steam into mechanical energy, and the generators convert that mechanical energy into electrical energy [46] for use by the propulsion motors and other ...
The United States Navy Nuclear Propulsion community consists of Naval Officers and Enlisted members who are specially trained to run and maintain the nuclear reactors that power the submarines and aircraft carriers of the United States Navy. Operating more than 80 nuclear-powered ships, the United States Navy is currently the largest naval ...
Seawolf was the same basic "double hull" twin-screw submarine design as her predecessor USS Nautilus (SSN-571), but her propulsion system was more technologically advanced. The Submarine Intermediate Reactor (SIR) nuclear plant was designed by General Electric's Knolls Atomic Power Laboratory and prototyped in West Milton, New York.
