S5W
The S5W reactor is a nuclear reactor used by the United States Navy to provide electricity generation and propulsion on warships. The S5W designation stands for: * S = Submarine platform * 5 = Fifth generation core designed by the contractor * W = Westinghouse was the contracted designer History The S5W was the standard reactor for submarines of the United States Navy from its first use in 1959 on until the introduction of the s with S6G reactor in the mid-1970s. One S5W plant was also used in the United Kingdom on the Royal Navy's first nuclear-powered submarine . Some time before 1971, the S5W vessel and core replaced the S1W reactor vessel and core at the S1W prototype facility. Even though operating an S5W reactor core, the facility continued to be called S1W. To use the additional power generated by the S5W reactor at higher power levels, steam dumps were constructed in the same S1W building but outside the original submarine style hull. , one S5W reactor plant remain ...

S1W Reactor
The S1W reactor was the first prototype naval reactor used by the United States Navy to prove that the technology could be used for electricity generation and propulsion on submarines. The designation of "S1W" stands for * S = Submarine platform * 1 = First generation core designed by the contractor * W = Westinghouse was the contracted designer and is a later Navy designation. During the plant's early years the project name was "Submarine Thermal Reactor" (STR) The land-based nuclear reactor was built at the National Reactor Testing Station, later called Idaho National Engineering Laboratory near Arco, Idaho. 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. The specific location within the vast Idaho National Laboratory where the S1W prototype was located was the Naval Reactors Facility. Design Under the leadership of Captain (later Admiral) Hyman G. Rickover, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
S3G Reactor
The S3G reactor is a naval reactor used by the United States Navy to provide electricity generation and propulsion on warships. The S3G designation stands for: * S = Submarine platform * 3 = Third generation core designed by the contractor * G = General Electric was the contracted designer Design This nuclear reactor generates 78 MW. It consists of a highly enriched uranium core with a 2-loop pressurized water reactor. History This design, designated as S4G, was used for the two reactors on the USS ''Triton'' (SSRN-586); no other ships used this reactor plant. The plant had unique design features such as horizontal steam generator U-tubes, and it was one of the only submarine plants with a deaereating feed tank (DFT). A prototype reactor was built ashore at Knolls Atomic Power Laboratory's Kesselring Site in West Milton, New York in 1958 to test the reactor design. Once the design was proven, the prototype continued operation to train students and test new systems a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
USS Daniel Webster (MTS-626)
USS ''Daniel Webster'' (SSBN-626), a ballistic missile submarine (FBM), was the only ship of the United States Navy to be named for Senator Daniel Webster. Construction and commissioning The contract to build ''Daniel Webster'' was awarded to the Electric Boat Division of General Dynamics Corporation in Groton, Connecticut, on 3 February 1961 and her keel was laid down there on 28 December 1961.

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 ...

Pressurized Water Reactor
A pressurized water reactor (PWR) is a type of light-water reactor, light-water nuclear reactor. PWRs constitute the large majority of the world's nuclear power plants (with notable exceptions being the UK, Japan and Canada). In a PWR, the primary nuclear reactor coolant, coolant (water) is pumped under high pressure to the reactor core where it is heated by the energy released by the Nuclear fission, fission of atoms. The heated, high pressure water then flows to a Water-tube boiler, steam generator, where it transfers its thermal energy to lower pressure water of a secondary system where steam is generated. The steam then drives turbines, which spin an electric generator. In contrast to a boiling water reactor (BWR), pressure in the primary coolant loop prevents the water from boiling within the reactor. All light-water reactors use ordinary water as both coolant and neutron moderator. Most use anywhere from two to four vertically mounted steam generators; VVER reactors use horizo ...

Royal Navy
The Royal Navy (RN) is the United Kingdom's naval warfare force. Although warships were used by English and Scottish kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years' War against France. The modern Royal Navy traces its origins to the early 16th century; the oldest of the UK's armed services, it is consequently known as the Senior Service. From the middle decades of the 17th century, and through the 18th century, the Royal Navy vied with the Dutch Navy and later with the French Navy for maritime supremacy. From the mid 18th century, it was the world's most powerful navy until the Second World War. The Royal Navy played a key part in establishing and defending the British Empire, and four Imperial fortress colonies and a string of imperial bases and coaling stations secured the Royal Navy's ability to assert naval superiority globally. Owing to this historical prominence, it is common, even among non-Britons, to ref ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
