Beznau Nuclear Power Plant
The Beznau nuclear power plant (german: Kernkraftwerk Beznau ''KKB is a nuclear power plant of the Swiss energy utility Axpo, located in the municipality Döttingen, Canton of Aargau, Switzerland, on an artificial island in the Aar river. The plant has been operating since September 1969. History Beznau 1 and 2 Beznau 1 is the first commercial nuclear power reactor in Switzerland. Putting an end to the traditional predilection of the Swiss power utilities for hydroelectric power, in the beginning of the 1960s the then Nordostschweizerische Kraftwerke AG (NOK, now part of Axpo Holding) started to take into account the construction of a nuclear power plant. On 23 December 1964 the Swiss Federal Office of Energy recognized the artificial island in Beznau as potential location for a reactor. The corresponding construction permit was issued on 2 November 1965 and, after only four years, on 12 May 1969 commissioning was authorized. On 24 December 1969 Beznau 1 started commer ...

Generation III Reactor
Generation III reactors, or Gen III reactors, are a class of nuclear reactors designed to succeed Generation II reactors, incorporating evolutionary improvements in design. These include improved fuel technology, higher thermal efficiency, significantly enhanced safety systems (including passive nuclear safety), and standardized designs intended to reduce maintenance and capital costs. They are promoted by the Generation IV International Forum (GIF). The first Generation III reactors to begin operation were Kashiwazaki 6 and 7 advanced boiling water reactors (ABWRs) in 1996 and 1997. Since 2012, both have been shut down due to security concerns. Due to the prolonged period of stagnation in the construction of new reactors and the continued (albeit declining) popularity of Generation II/II+ designs in new construction, relatively few third generation reactors have been built. Overview The older Gen II reactors comprise the vast majority of current nuclear reactors. Gen III re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Klingnau
Klingnau is a municipality in the district of Zurzach in the canton of Aargau in Switzerland. History Klingnau is first mentioned in 1239 as ''Chlingenowe''. Ulrich of Klingen acquired land from the monastery of St. Blaise in 1239 to found the city. He and the abbot reached an agreement over which of the abbey's own peasants could move to the new town. The von Klingen family granted extensive lands around the city to the Knights Hospitaller between 1251 and 1268. The knights owned so much property that in 1268 they moved their order house from Leuggern to Klingnau. They were given a separate gate in the city walls. Walther of Klingen sold the city and surroundings to his cousin the Bishop of Constance Eberhard von Waldburg in 1269. The new owner then appointed a bailiff in the town. Klingnau became the seat of an outer district that included Koblenz, Siglistorf, Mellstorf, Döttingen and Zurzach. In 1314, Klingnau was granted town privileges. Every year at midsummer the c ...

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 ...

District Heating
District heating (also known as heat networks or teleheating) is a system for distributing heat generated in a centralized location through a system of insulated pipes for residential and commercial heating requirements such as space heating and water heating. The heat is often obtained from a cogeneration plant burning fossil fuels or biomass, but heat-only boiler stations, geothermal heating, heat pumps and central solar heating are also used, as well as heat waste from factories and nuclear power electricity generation. District heating plants can provide higher efficiencies and better pollution control than localized boilers. According to some research, district heating with combined heat and power (CHPDH) is the cheapest method of cutting carbon emissions, and has one of the lowest carbon footprints of all fossil generation plants. Fifth-generation district heat networks do not use combustion on-site and have zero emissions of CO and NO on-site; they employ heat transfer u ...

Brown, Boveri & Cie
Brown, Boveri & Cie. (Brown, Boveri & Company; BBC) was a Swiss group of electrical engineering companies. It was founded in Zürich, in 1891 by Charles Eugene Lancelot Brown and Walter Boveri who worked at the Maschinenfabrik Oerlikon. In 1970 BBC took over the Maschinenfabrik Oerlikon. In 1988 it merged with ASEA to form ABB. Early History of BBC Brown Boveri BBC Brown Boveri was established in 1891. The company was one of only a few multinational corporations to operate subsidiaries that were larger than the parent company. Because of the limitations of the Swiss domestic market, Brown Boveri established subsidiaries throughout Europe relatively early in its history, and at times had difficulty maintaining managerial control over some of its larger operating units. The merger with ASEA, a company which was praised for its strong management, was expected to help Brown Boveri reorganize and reassert control over its vast international network. Activity in Britain Brown Bove ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Swiss Federal Nuclear Safety Inspectorate
The Swiss Federal Nuclear Safety Inspectorate (german: Eidgenössisches Nuklearsicherheitsinspektorat (ENSI)) is Switzerland's regulatory supervisory authority for nuclear safety and for the security of nuclear installations; it supervises the nuclear power plants at Beznau, Gösgen, Leibstadt and Mühleberg, the research reactors at the Paul Scherrer Institute, the University of Basel and the Swiss Federal Institute of Technology (Ecole Polytechnique Fédérale de Lausanne), as well as the Swiss national central interim storage facility for radioactive waste ( ZWILAG). ENSI's headquarters are located in Brugg in the Canton of Aargau. For its part, ENSI is supervised by the ENSI Board: this body is elected by the Swiss Federal Council, to which it reports directly. History Until the end of 2008, the Principal Nuclear Safety Division (HSK) within the Swiss Federal Office for Energy (SFOE) was the technical supervisory body responsible for nuclear plants in Switzerland. Its headq ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MOX Fuel
Mixed oxide fuel, commonly referred to as MOX fuel, is nuclear fuel that contains more than one oxide of fissile material, usually consisting of plutonium blended with natural uranium, reprocessed uranium, or depleted uranium. MOX fuel is an alternative to the low-enriched uranium (LEU) fuel used in the light-water reactors that predominate nuclear power generation. For example, a mixture of 7% plutonium and 93% natural uranium reacts similarly, although not identically, to LEU fuel (3 to 5% uranium-235). MOX usually consists of two phases, UO2 and PuO2, and/or a single phase solid solution (U,Pu)O2. The content of PuO2 may vary from 1.5 wt.% to 25–30 wt.% depending on the type of nuclear reactor. One attraction of MOX fuel is that it is a way of utilizing surplus weapons-grade nuclear material, weapons-grade plutonium, an alternative to storage of surplus plutonium, which would need to be secured against the risk of theft for use in nuclear weapons. On the other hand, some st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
