The Neckar is a 362-kilometre-long (225 mi) river in Germany, mainly flowing through the southwestern state of Baden-Württemberg, with a short section through Hesse. The Neckar is a major right tributary of the Rhine. Rising in the Schwarzwald-Baar-Kreis near Schwenningen in the Schwenninger Moos conservation area at a height of 706 m (2,316 ft) above sea level, it passes through Rottweil, Rottenburg am Neckar, Kilchberg, Tübingen, Wernau, Nürtingen, Plochingen, Esslingen, Stuttgart, Ludwigsburg, Marbach, Heilbronn and Heidelberg, before discharging on average 145 m3/s (5,100 cu ft/s) of water into the Rhine at Mannheim, at 95 m (312 ft) above sea level, making the Neckar its 4th largest tributary, and the 10th largest river in Germany. Since 1968, the Neckar has been navigable for cargo ships via 27 locks for about 200 kilometres (120 mi) upstream from Mannheim to the river port of Plochingen, at the confluence with the Fils.
Dry cask storage is a method of storing high-level radioactive waste, such as spent nuclear fuel that has already been cooled in the spent fuel pool for at least one year and often as much as ten years. Casks are typically steel cylinders that are either welded or bolted closed. The fuel rods inside are surrounded by inert gas. Ideally, the steel cylinder provides leak-tight containment of the spent fuel. Each cylinder is surrounded by additional steel, concrete, or other material to provide radiation shielding to workers and members of the public.
The Army Nuclear Power Program (ANPP) was a program of the United States Army to develop small pressurized water and boiling water nuclear power reactors to generate electrical and space-heating energy primarily at remote, relatively inaccessible sites. The ANPP had several accomplishments, but ultimately it was considered to be "a solution in search of a problem." The U.S. Army Engineer Reactors Group managed this program and it was headquartered at Fort Belvoir, Virginia. The program began in 1954 and had effectively terminated by about 1977, with the last class of NPP operators graduating in 1977. Work continued for some time thereafter either for decommissioning of the plants or placing them into SAFSTOR. The current development of small modular reactors has led to a renewed interest in military applications.
Neckarwestheim is a municipality with 3524 inhabitants in the Heilbronn district, Baden-Württemberg, in south-west Germany. It is located on the Neckar river and is well known as the location of a nuclear power station, the Neckarwestheim Nuclear Power Plant.
EnBW Energie Baden-Württemberg AG, or simply EnBW, is a publicly-traded energy company headquartered in Karlsruhe, Germany. As its name indicates, EnBW is based in the German state of Baden-Württemberg.
The THTR-300 was a thorium cycle high-temperature nuclear reactor rated at 300 MW electric (THTR-300) in Hamm-Uentrop, Germany. It started operating in 1983, synchronized with the grid in 1985, operated at full power in February 1987 and was shut down September 1, 1989. The THTR-300 served as a prototype high-temperature reactor (HTR) to use the TRISO pebble fuel produced by the AVR, an experimental pebble bed operated by VEW. The THTR-300 cost €2.05 billion and was predicted to cost an additional €425 million through December 2009 in decommissioning and other associated costs. The German state of North Rhine Westphalia, Federal Republic of Germany, and Hochtemperatur-Kernkraftwerk GmbH (HKG) financed the THTR-300’s construction.
The BN-350 is a sodium-cooled, fast reactor located at the Mangyshlak Nuclear Power Plant, located in Aktau, Kazakhstan, on the shore of the Caspian Sea.
Yankee Rowe Nuclear Power Station was a nuclear power plant in Rowe, Massachusetts, located on the Deerfield River in the town of Rowe in western Massachusetts. Its 180 MWe pressurized water reactor operated from 1961 to 1991. It produced electricity for New England consumers. The site is referred to as "Yankee-Rowe" or simply "Rowe", to avoid confusion with Vermont Yankee, another nuclear power station located in nearby Vernon, Vermont. The decommissioning of the site was completed in 2007.
Nuclear decommissioning is the process leading to the irreversible complete or partial closure of a nuclear facility, usually a nuclear reactor, with the ultimate aim at termination of the operating licence. The process usually runs according to a decommissioning plan, including the whole or partial dismantling and decontamination of the facility, ideally resulting in restoration of the environment up to greenfield status. The decommissioning plan is fulfilled when the approved end state of the facility has been reached.
Obrigheim is a town in the district of Neckar-Odenwald-Kreis, in Baden-Württemberg, Germany.
Nuclear power was used in Germany from the 1960s until being phased out on April 15, 2023.
KS 150 is a Gas Cooled Reactor using Heavy Water as a moderator (GCHWR) nuclear reactor design. A single example, A-1, was constructed at the Bohunice Nuclear Power Plant in Jaslovské Bohunice, Czechoslovakia. The power plant suffered a series of accidents, the worst being an accident on February 22, 1977, rated INES-4. Since 1979 the plant has been undergoing decommissioning.
Neckarwestheim Nuclear Power Station is a nuclear power plant in Neckarwestheim, Germany, sometimes abbreviated GKN, operated by EnBW Kernkraft GmbH, a subsidiary of EnBW.
The Gösgen Nuclear Power Plant is located in the Däniken municipality on a loop of the Aar river. It is operated by the ad hoc society Kernkraftwerk Gösgen-Däniken AG.
Stade Nuclear power plant operated from 1972 to 2003 in Bassenfleth close to the Schwinge river mouth into the Elbe river. It was the first nuclear plant shut down after Germany's nuclear phase out legislation and is currently being decommissioned.
Greifswald nuclear power station, also known as Lubmin nuclear power station, was the largest nuclear power station in East Germany before closure shortly after the German reunification. The plants were of the VVER-440/V-230 type, which was the second generation of Soviet-designed plants. The plant is in Lubmin near Greifswald, in the state of Mecklenburg-Vorpommern.
The anti-nuclear movement in Germany has a long history dating back to the early 1970s when large demonstrations prevented the construction of a nuclear plant at Wyhl. The Wyhl protests were an example of a local community challenging the nuclear industry through a strategy of direct action and civil disobedience. Police were accused of using unnecessarily violent means. Anti-nuclear success at Wyhl inspired nuclear opposition throughout Germany, in other parts of Europe, and in North America. A few years later protests raised against the NATO Double-Track Decision in Germany and were followed by the foundation of the Green party.
The Humboldt Bay Power Plant, Unit 3 was a 63 MWe nuclear boiling water reactor, owned by Pacific Gas and Electric Company that operated from August 1963 to July 1976 just south of Eureka, California.
Großwelzheim Nuclear Power Plant,, was an experimental nuclear power plant consisting of one 25 MW reactor in Großwelzheim, a district of Karlstein am Main.
Niederaichbach Nuclear Power Plant was a German nuclear plant in Niederaichbach, Bavaria. The plant consisted of one heavy water gas cooled (HWGC) reactor with a gross capacity of 106 MWe. Safety and maintenance issues caused the reactor to be decommissioned after only a year and a half in operation. It was the first nuclear plant in Europe to be completely decommissioned, with the final work being completed in autumn 1995.
