Unterweser Nuclear Power Plant
Unterweser nuclear power station is an inactive nuclear power plant in Kleinensiel (Stadland municipality), near Nordenham, Lower Saxony, Germany. It consists of a single Nuclear reactor, reactor with a nameplate capacity of 1410MWe, which operated from 1978 until 2011. History Construction began on July 1st, 1972, and the power plant was commissioned on September 29th, 1978. At the time of the reactor's commissioning, it was the largest nuclear reactor in the world. It had 193 fuel assemblies. Unterweser was one of the seven reactors shut down on 17 March 2011 (although actual shutdown was several days later, as the nuclear Nuclear fuel, fuel rods take time to cool down) pending the results of a three-month moratorium on nuclear power. On 30 May 2011, the German government announced that Unterweser would not be returning to operation following the moratorium and would be decommissioned. The final fuel rods were removed in February 2019. Gallery Image:KKW-Unterweser.jpg, The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Weser
The Weser () is a river of Lower Saxony in north-west Germany. It begins at Hannoversch Münden through the confluence of the Werra and Fulda. It passes through the Hanseatic city of Bremen. Its mouth is further north against the ports of Bremerhaven and Nordenham. The latter is on the Butjadingen Peninsula. It then merges into the North Sea The North Sea lies between Great Britain, Denmark, Norway, Germany, the Netherlands, Belgium, and France. A sea on the European continental shelf, it connects to the Atlantic Ocean through the English Channel in the south and the Norwegian Se ... via two highly Saline water, saline, Estuary, estuarine mouths. It connects to the canal network running east–west across the North German Plain. The river, when combined with the Werra (a dialectal form of ''Weser''), is long and thus, the longest river entirely situated within Germany (the Main (river), Main, however, is the longest if the Weser-Werra are considered separate). ...

Nuclear Power Plant
A nuclear power plant (NPP), also known as a nuclear power station (NPS), nuclear generating station (NGS) or atomic power station (APS) is a thermal power station in which the heat source is a nuclear reactor. As is typical of thermal power stations, heat is used to generate steam that drives a steam turbine connected to a electric generator, generator that produces electricity. , the International Atomic Energy Agency reported that there were 410 nuclear power reactors in operation in 32 countries around the world, and 57 nuclear power reactors under construction. Most nuclear power plants use thermal reactors with enriched uranium in a Nuclear fuel cycle#Once-through nuclear fuel cycle, once-through fuel cycle. Fuel is removed when the percentage of neutron poison, neutron absorbing atoms becomes so large that a nuclear chain reaction, chain reaction can no longer be sustained, typically three years. It is then cooled for several years in on-site spent fuel pools be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stadland
Stadland () is a municipality in the district of Wesermarsch, in Lower Saxony, Germany.

Lower Saxony
Lower Saxony is a States of Germany, German state (') in Northern Germany, northwestern Germany. It is the second-largest state by land area, with , and fourth-largest in population (8 million in 2021) among the 16 ' of the Germany, Federal Republic of Germany. In rural areas, Northern Low Saxon and Saterland Frisian language, Saterland Frisian are still spoken, though by declining numbers of people. Lower Saxony borders on (from north and clockwise) the North Sea, the states of Schleswig-Holstein, Hamburg, , Brandenburg, Saxony-Anhalt, Thuringia, Hesse and North Rhine-Westphalia, and the Netherlands. Furthermore, the Bremen (state), state of Bremen forms two enclaves within Lower Saxony, one being the city of Bremen, the other its seaport, Bremerhaven (which is a semi-exclave, as it has a coastline).

Nuclear Reactor
A nuclear reactor is a device used to initiate and control a Nuclear fission, fission nuclear chain reaction. They are used for Nuclear power, commercial electricity, nuclear marine propulsion, marine propulsion, Weapons-grade plutonium, weapons production and Research reactor, research. Fissile material, Fissile nuclei (primarily uranium-235 or plutonium-239) absorb single neutron, neutrons and split, releasing energy and multiple neutrons, which can induce further fission. Reactors stabilize this, regulating Neutron absorber, neutron absorbers and neutron moderator, moderators in the core. Fuel efficiency is exceptionally high; Enriched uranium#Low-enriched uranium (LEU), low-enriched uranium is 120,000 times more energy dense than coal. Heat from nuclear fission is passed to a working fluid Nuclear reactor#By coolant, coolant. In commercial reactors, this drives Turbine, turbines and electrical generator shafts. Some reactors are used for district heating, and isotopes, isoto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuclear Fuel
Nuclear fuel refers to any substance, typically fissile material, which is used by nuclear power stations or other atomic nucleus, nuclear devices to generate energy. Oxide fuel For fission reactors, the fuel (typically based on uranium) is usually based on the metal oxide; the oxides are used rather than the metals themselves because the oxide melting point is much higher than that of the metal and because it cannot burn, being already in the oxidized state. Uranium dioxide Uranium dioxide is a black semiconductor, semiconducting solid. It can be made by heating uranyl nitrate to form . : This is then converted by heating with hydrogen to form UO2. It can be made from Enriched uranium, enriched uranium hexafluoride by reacting with ammonia to form a solid called ammonium diuranate, . This is then heated (Calcination, calcined) to form and U3O8 which is then converted by heating with hydrogen or ammonia to form UO2. The UO2 is mixed with an organic binder and pressed in ...

Nuclear Power In Germany
Nuclear power was used in Germany from the 1960s until it was fully phased out in April 2023. German nuclear power began with research reactors in the 1950s and 1960s, with the first commercial plant coming online in 1969. By 1990, nuclear power accounted for about a quarter of the electricity produced in the country. Nuclear power accounted for 13.3% of German electricity supply in 2021, supplied by six power plants. Three of these were switched off at the end of 2021, and the other three ceased operations by April 2023. The anti-nuclear movement in Germany has a long history dating back to the early 1970s and intensified following the Chernobyl disaster in 1986. After the March 2011 Fukushima nuclear disaster and subsequent anti-nuclear protests, the government announced that it would close all of its nuclear power plants by 2022. Eight of the 17 operating reactors in Germany were permanently shut down following Fukushima. While nuclear power was gradually phased out of the G ...

Former Nuclear Power Stations In Germany
A former is an object, such as a template, gauge or cutting die, which is used to form something such as a boat's hull. Typically, a former gives shape to a structure that may have complex curvature. A former may become an integral part of the finished structure, as in an aircraft fuselage, or it may be removable, being used in the construction process and then discarded or re-used. Aircraft formers Formers are used in the construction of aircraft fuselage, of which a typical fuselage has a series from the nose cone to the empennage, typically perpendicular to the longitudinal axis of the aircraft. The primary purpose of formers is to establish the shape of the fuselage and reduce the column length of stringers to prevent instability. Formers are typically attached to longerons, which support the skin of the aircraft. The "former-and-longeron" technique (also called stations and stringers) was adopted from boat construction, and was typical of light aircraft built until t ...
