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).
The land-based nuclear reactor was built at the National Reactor Testing Station, later called Idaho National Engineering Laboratory near Arco, Idaho. [1] The plant was the prototype for the power system of USS Nautilus (SSN-571) , the world's first nuclear-powered submarine, which used the improved S2W reactor .
Today’s submarines are all nuclear-powered, and those propulsion systems all got their start in Idaho. The Naval Reactors Facility at INL continues to play a central role in nuclear propulsion ...
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 ...
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 ...
The U.S. nuclear submarine fleet is in trouble and needs help on production and repairs. FILE: In this handout image provided by the U.S. Navy, the Los Angeles-class attack submarine USS Tuscon ...
[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 ...
