SNUPPS
SNUPPS is an acronym standing for Standardized Nuclear Unit Power Plant System. It refers to a 4-loop PWR reactor design produced by Westinghouse in the 1970s. The design was developed for four USA utilities, and plants were built at Callaway and Wolf Creek. The UK plant at Sizewell B The Sizewell nuclear site consists of two nuclear power stations, one of which is still operational, located near the small fishing village of Sizewell in Suffolk, England.

Sizewell Nuclear Power Stations
The Sizewell nuclear site consists of two nuclear power stations, one of which is still operational, located near the small fishing village of Sizewell in Suffolk, England. Sizewell A, with two Magnox reactors, is now in the process of being decommissioned. Sizewell B has a single pressurised water reactor (PWR) and is the UK's newest nuclear power station. A third power station, to consist of twin EPR reactors, is planned to be built as Sizewell C. Sizewell A Site The site of Sizewell A occupies north of Sizewell. It is on a low plateau above flood level. The geological foundation comprises Norwich Crag Formation and Red Crag Formation bedrock of Pleistocene age above Eocene London Clay. The Crag deposits predominantly consist of medium dense and dense sands with thin layers of clay and silt and fossiliferous shelly horizons. The Crag strata extend to a depth of below ground level. In 1972/73, Sizewell A was awarded the Christopher Hinton trophy in recognition of good h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Callaway Nuclear Generating Station
The Callaway Plant is a nuclear power plant located on a site in Callaway County, Missouri, near Fulton, Missouri. It began operating on December 19, 1984. The plant, which is the state's only commercial nuclear unit, has one 1,190-megawatt Westinghouse four-loop pressurized water reactor and a General Electric turbine-generator. It is owned by the Ameren Corporation and operated by subsidiary Ameren Missouri. It is one of several Westinghouse reactors built to a design called Standard Nuclear Unit Power Plant System, or SNUPPS. Surrounding population The Nuclear Regulatory Commission defines two emergency planning zones around nuclear power plants: a plume exposure pathway zone with a radius of , concerned primarily with exposure to, and inhalation of, airborne radioactive contamination, and an ingestion pathway zone of about , concerned primarily with ingestion of food and liquid contaminated by radioactivity. The 2010 population within of Callaway was 10,092, an in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Westinghouse Electric Corporation (1886)
The Westinghouse Electric Corporation was an American manufacturing company founded in 1886 by George Westinghouse. It was originally named "Westinghouse Electric & Manufacturing Company" and was renamed "Westinghouse Electric Corporation" in 1945. The company acquired the CBS television network in 1995 and was renamed "CBS Corporation" until being acquired by Viacom in 1999, a merger completed in April 2000. The CBS Corporation name was later reused for one of the two companies resulting from the split of Viacom in 2006. The Westinghouse trademarks are owned by Westinghouse Electric Corporation, and were previously part of Westinghouse Licensing Corporation. The nuclear power business, Westinghouse Electric Company, was spun off from the Westinghouse Electric Corporation in 1999. History Westinghouse Electric was founded by George Westinghouse in Pittsburgh, Pennsylvania, on January 8, 1886. The firm became active in developing electric infrastructure throughout the U ...

Wolf Creek Generating Station
Wolf Creek Generating Station, a nuclear power plant located near Burlington, Kansas, occupies 9,818 acres (40 km²) of the total controlled by the owner. Wolf Creek, dammed to create Coffey County Lake (formerly Wolf Creek Lake), provides not only the name, but water for the condensers. History This plant has one Westinghouse pressurized water reactor that came on line on June 4, 1985. The reactor was rated at 1,170 MW(e). A new turbine generator rotor was installed in 2011 that increased electrical output to approximately 1250 MW(e). The reactor output remained unchanged at 3565 MW (th). On October 4, 2006, the operator applied to the Nuclear Regulatory Commission (NRC) for a renewal and extension of the plant's operating license. The NRC granted the renewal on November 20, 2008, extending the license from forty years to sixty. On Jan 13, 2012 at 2 p.m., due to a breaker failure and an unexplained loss of power to an electrical transformer, the p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
