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 (physics), power for Marine nuclear propulsion, 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 power, 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 (United States Department of Energy, Department of Energy) owned and prime contractor-operated facilities: Be ...

Naval Reactor Compartment Packages In Trench 94 At Hanford, WA
A navy, naval force, or maritime force is the branch of a nation's armed forces principally designated for naval warfare, naval and amphibious warfare; namely, lake-borne, riverine, littoral zone, littoral, or ocean-borne combat operations and related functions. It includes anything conducted by surface Naval ship, ships, amphibious warfare, amphibious ships, submarines, and seaborne naval aviation, aviation, as well as ancillary support, communications, training, and other fields. The strategic offensive role of a navy is Power projection, projection of force into areas beyond a country's shores (for example, to protect Sea lane, sea-lanes, deter or confront piracy, ferry troops, or attack other navies, ports, or shore installations). The strategic defensive purpose of a navy is to frustrate seaborne projection-of-force by enemies. The strategic task of the navy also may incorporate nuclear deterrence by use of submarine-launched ballistic missiles. Naval operations can be broa ...

Idaho
Idaho ( ) is a state in the Pacific Northwest region of the Western United States. To the north, it shares a small portion of the Canada–United States border with the province of British Columbia. It borders the states of Montana and Wyoming to the east, Nevada and Utah to the south, and Washington and Oregon to the west. The state's capital and largest city is Boise. With an area of , Idaho is the 14th largest state by land area, but with a population of approximately 1.8 million, it ranks as the 13th least populous and the 7th least densely populated of the 50 U.S. states. For thousands of years, and prior to European colonization, Idaho has been inhabited by native peoples. In the early 19th century, Idaho was considered part of the Oregon Country, an area of dispute between the U.S. and the British Empire. It officially became U.S. territory with the signing of the Oregon Treaty of 1846, but a separate Idaho Territory was not organized until 1863, instead ...

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 pressurize ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
S9G Reactor
The S9G reactor is a United States Naval reactor, naval reactor used by the United States Navy to provide electricity generation and Nuclear marine propulsion, propulsion on Virginia class submarine, ''Virginia'' class submarines. The S9G designation stands for: * S, Submarine platform * 9, Ninth generation Nuclear reactor core, core designed by the contractor * G, General Electric was the contracted designer Design This pressurized water reactor (PWR) style nuclear reactor, designed by Knolls Atomic Power Laboratory (then managed by General Electric), is designed to have increased energy density, and new plant components, including a new steam generator design featuring improved corrosion resistance and reduced life-cycle costs. The steam generator will alleviate the corrosion concerns encountered in existing designs of steam generators, while reducing component size and weight and providing greater flexibility in overall arrangement. The reactor is designed to operate for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
