United States Naval Reactor
United States naval reactors are nuclear reactors used by the United States Navy aboard certain ships to generate the steam used to produce power for propulsion, electric power, catapulting airplanes in aircraft carriers, and a few more minor uses. Such naval nuclear reactors have a complete power plant associated with them. All U.S. Navy submarines and supercarriers built since 1975 are nuclear-powered by such reactors. There are no commissioned conventional (non-nuclear) submarines or aircraft carriers left in the U.S. Navy, since the last conventional carrier, , was decommissioned in May 2009. The U.S. Navy had nine nuclear-powered cruisers with such reactors also, but they have since been decommissioned. Reactors are designed by a variety of contractors, then developed and tested at one of several government (Department of Energy) owned and prime contractor-operated facilities: Bettis Atomic Power Laboratory in West Mifflin, Pennsylvania and its associated Naval Reactors Fa ...

Electricity Generation
Electricity generation is the process of generating electric power from sources of primary energy. For utilities in the electric power industry, it is the stage prior to its delivery ( transmission, distribution, etc.) to end users or its storage (using, for example, the pumped-storage method). Electricity is not freely available in nature, so it must be "produced" (that is, transforming other forms of energy to electricity). Production is carried out in power stations (also called "power plants"). Electricity is most often generated at a power plant by electromechanical generators, primarily driven by heat engines fueled by combustion or nuclear fission but also by other means such as the kinetic energy of flowing water and wind. Other energy sources include solar photovoltaics and geothermal power. There are also exotic and speculative methods to recover energy, such as proposed fusion reactor designs which aim to directly extract energy from intense magnetic fields gene ...

Nuclear Marine Propulsion
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. Nuclear propulsion is used primarily within naval warships such as nuclear submarines and supercarriers. A small number of experimental civil nuclear ships have been built. Compared to oil- or coal-fuelled ships, nuclear propulsion offers the advantages of very long intervals of operation before refueling. All the fuel is contained within the nuclear reactor, so no cargo or supplies space is taken up by fuel, nor is space taken up by exhaust stacks or combustion air intakes. However, the low fuel cost is offset by high operating costs and investment in infrastructure, so nearly all nuclear-powered vessels are military. Power plants Basic operation of naval ship or submarine Most naval nuclear reactors are of the pressuriz ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Warship
A warship or combatant ship is a naval ship that is built and primarily intended for naval warfare. Usually they belong to the armed forces of a state. As well as being armed, warships are designed to withstand damage and are usually faster and more maneuverable than merchant ships. Unlike a merchant ship, which carries cargo, a warship typically carries only weapons, ammunition and supplies for its crew. Warships usually belong to a navy, though they have also been operated by individuals, cooperatives and corporations. In wartime, the distinction between warships and merchant ships is often blurred. In war, merchant ships are often armed and used as armed merchantman, auxiliary warships, such as the Q-ships of the First World War and the armed merchant cruisers of the Second World War. Until the 17th century it was common for merchant ships to be pressed into naval service and not unusual for more than half a Naval fleet, fleet to be composed of merchant ships. Until the th ...

Submarine
A submarine (or sub) is a watercraft capable of independent operation underwater. It differs from a submersible, which has more limited underwater capability. The term is also sometimes used historically or colloquially to refer to remotely operated vehicles and Autonomous underwater vehicle, robots, as well as medium-sized or smaller vessels, such as the midget submarine and the wet sub. Submarines are referred to as ''boats'' rather than ''ships'' irrespective of their size. Although experimental submarines had been built earlier, submarine design took off during the 19th century, and they were adopted by several navies. They were first widely used during World War I (1914–1918), and are now used in many navy, navies, large and small. Military uses include attacking enemy surface ships (merchant and military) or other submarines, and for aircraft carrier protection, Blockade runner, blockade running, Ballistic missile submarine, nuclear deterrence, reconnaissance, conventio ...

Nuclear Reactor Core
A nuclear reactor core is the portion of a nuclear reactor containing the nuclear fuel components where the nuclear reactions take place and the heat is generated. Typically, the fuel will be low-enriched uranium contained in thousands of individual fuel pins. The core also contains structural components, the means to both moderate the neutrons and control the reaction, and the means to transfer the heat from the fuel to where it is required, outside the core. Water-moderated reactors Inside the core of a typical pressurized water reactor or boiling water reactor are fuel rods with a diameter of a large gel-type ink pen, each about 4 m long, which are grouped by the hundreds in bundles called "fuel assemblies". Inside each fuel rod, pellets of uranium, or more commonly uranium oxide, are stacked end to end. Also inside the core are control rods, filled with pellets of substances like boron or hafnium or cadmium that readily capture neutrons. When the control rods are low ...

Combustion Engineering
Combustion Engineering (C-E) was a multi-national American-based engineering firm that developed nuclear steam supply power systems in the United States. Originally headquartered in New York City, C-E moved its corporate offices to Stamford, Connecticut in 1973. C-E owned over three dozen other companies including Lummus Company, National Tank Company and the Morgan Door Company. The company was acquired by Asea Brown Boveri in early 1990. The boiler and fossil fuel businesses were purchased by Alstom in 2000, and the nuclear business was purchased by Westinghouse Electric Company also in 2000. History Founding Combustion Engineering was organized in 1912 through the merger of the Grieve Grate Company and the American Stoker Company, two well-known manufacturers of fuel burning equipment. The company was originally headquartered on 11 Broadway and at 43 ''-'' 5 ''-'' 7 Broad Street (Manhattan), both in Lower Manhattan. The city block was leased from the Alliance Realty Com ...

Nuclear Reactor
A nuclear reactor is a device used to initiate and control a fission nuclear chain reaction or nuclear fusion reactions. Nuclear reactors are used at nuclear power plants for electricity generation and in nuclear marine propulsion. Heat from nuclear fission is passed to a working fluid (water or gas), which in turn runs through steam turbines. These either drive a ship's propellers or turn electrical generators' shafts. Nuclear generated steam in principle can be used for industrial process heat or for district heating. Some reactors are used to produce isotopes for Nuclear medicine, medical and industrial radiography, industrial use, or for production of weapons-grade plutonium. , the International Atomic Energy Agency reports there are 422 nuclear power reactors and 223 nuclear research reactors in operation around the world. In the early era of nuclear reactors (1940s), a reactor was known as a nuclear pile or atomic pile (so-called because the graphite moderator blocks of th ...

S1C Reactor
The S1C reactor was a prototype naval reactor designed for the United States Navy to provide electricity generation and propulsion on warships. The S1C designation stands for: * S = Submarine platform * 1 = First generation core designed by the contractor * C = Combustion Engineering (C-E) was the contracted designer History This nuclear reactor was built in Windsor, Connecticut as a prototype for the experimental USS ''Tullibee'' (SSN-597) submarine, though that boat was in fact powered by a S2C reactor. Unusual for a nuclear submarine propulsion plant, steam turbines powered generators, which in turn powered an electric motor. This eliminated the need for reduction gears and their associated underwater noise. The USS ''Tullibee'' was an early advanced-design, fast-attack submarine constructed by Electric Boat and commissioned in 1960. Throughout the Cold War, the S1C Prototype nuclear submarine propulsion plant at the Windsor Site (41°52'44"N 72°43'03"W) supp ...

USS Tullibee (SSN-597)
USS ''Tullibee'' (SSN-597), a unique submarine, was the second ship of the United States Navy to be named for the tullibee, any of several whitefishes of central and northern North America. At 273 feet long and 2,640 tons displacement, USS ''Tullibee'' was the smallest nuclear-powered attack submarine in the US submarine fleet, although she was originally designed mainly for the anti-submarine (ASW) 'hunter-killer' role and was redesignated an attack submarine when the two roles were merged. The initial manning complement was 7 officers and 60 enlisted men. However before inactivation, the crew included 13 officers and over 100 enlisted men. During her career, ''Tullibee'' achieved much and conducted many submarine firsts. During her commissioned service she submerged and surfaced 730 times and traveled approximately equal to the distance from the earth to the moon and halfway back. Construction ''Tullibee'' was the result of Project Nobska, a study ordered in 1956 by Admi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
