Emsland
Landkreis Emsland () is a districts of Germany, district in Lower Saxony, Germany named after the river Ems (river), Ems. It is bounded by (from the north and clockwise) the districts of Leer (district), Leer, Cloppenburg (district), Cloppenburg and Osnabrück (district), Osnabrück, the state of North Rhine-Westphalia (district of Steinfurt (district), Steinfurt), the district of County of Bentheim (district), Bentheim in Lower Saxony, and the Netherlands (provinces of Drenthe and Groningen (province), Groningen). History For a long time the region of the Emsland was extremely sparsely populated, due to the fens on both sides of the river. Small villages were established in medieval times along the river and on the Hümmling. In the 13th century the bishops of Prince-Bishopric of Münster, Münster gained control over the region; the Emsland remained property of the bishop Reichsdeputationshauptschluss, until 1803, when the clerical states German mediatisation, were dissol ...

Neckarwestheim Nuclear Power Plant
Neckarwestheim Nuclear Power Station is a nuclear power plant in Neckarwestheim, Germany, sometimes abbreviated GKN (for ), operated by EnBW Kernkraft GmbH, a subsidiary of EnBW. As part of the nuclear power phase-out, it was taken out of service on April 15, 2023. GKN 1 Unit I, in service since 1976, carried a nominal electrical power of 840 megawatts. The 50 Hz three phase AC power was 567 megawatts and for the 16.7 Hz traction current power 174 MW. The traction current generator is the world's largest single-phase AC generators. The generator block 1 is rated 21,000 volts at a current of 27,000 amperes, and the traction current generator is rated 14,500 volts and a current of 12,000 amperes. The current produced by the generators was stepped up to 220 kilovolts (three-phase alternating current) or 110 kilovolts (single-phase traction current) with the unit transformers. Unit I was the only nuclear power station wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Nuclear Decommissioning
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. The process typically takes about 15 to 30 years, or many decades more when an interim ''safe storage'' period is applied for radioactive decay. Radioactive waste that remains after the decommissioning is either moved to an on-site storage facility where it is still under control of the owner, or moved to a dry cask storage or disposal facility at another location. The final disposal of nuclear waste from past and future decommissioning is a growing still un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

International Nuclear Event Scale
The International Nuclear and Radiological Event Scale (INES) was introduced in 1990 by the International Atomic Energy Agency (IAEA) in order to enable prompt communication of safety significant information in case of nuclear accidents. The scale is intended to be logarithmic, similar to the moment magnitude scale that is used to describe the comparative magnitude of earthquakes. Each increasing level represents an accident approximately ten times as severe as the previous level. Compared to earthquakes, where the event intensity can be quantitatively evaluated, the level of severity of a human-made disaster, such as a nuclear accident, is more subject to interpretation. Because of this subjectivity, the INES level of an incident is assigned well after the fact. The scale is therefore intended to assist in disaster-aid deployment. Details A number of criteria and indicators are defined to assure coherent reporting of nuclear events by different official authorities. There ...

Cooling Tower
A cooling tower is a device that rejects waste heat to the atmosphere through the cooling of a coolant stream, usually a water stream, to a lower temperature. Cooling towers may either use the evaporation of water to remove heat and cool the working fluid to near the Wet-bulb temperature, wet-bulb air temperature or, in the case of ''dry cooling towers'', rely solely on air to cool the working fluid to near the Dry-bulb temperature, dry-bulb air temperature using Radiator, radiators. Common applications include cooling the circulating water used in oil refineries, petrochemical and other chemical plants, thermal power stations, nuclear power stations and HVAC systems for cooling buildings. The classification is based on the type of air induction into the tower: the main types of cooling towers are Natural convection, natural draft and Forced convection, induced draft cooling towers. Cooling towers vary in size from small roof-top units to very large hyperboloid structures t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
