Gösgen Nuclear Power Plant
The Gösgen Nuclear Power Plant (in German ''Kernkraftwerk Gösgen'', abbreviated in KKG) is located in the Däniken municipality (canton of Solothurn, Switzerland) on a loop of the Aar river. It is operated by the ''ad hoc'' society Kernkraftwerk Gösgen-Däniken AG. History Construction The first discussions about the construction of the third Swiss nuclear power plant started in 1966. In 1970 the formal request was submitted to the federal authorities. Initially foreseeing a river water cooling, the blueprints had to be modified in order to meet a new federal regulation that in 1971 forbade such systems for future plants. After the introduction of a cooling tower, the authorities issued the location authorization on 31 October 1972. The construction started in summer 1973, after that a series of local permits had been granted. The commissioning was authorized on 29 September 1979. The KKG was ready to start operation in February 1979, but the Three Mile Island accident ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Olten
Olten (High Alemannic: ''Oute'') is a town in the canton of Solothurn in Switzerland and capital of the district of the same name. Olten's railway station is within 30 minutes of Zürich, Basel, Bern, and Lucerne by train, and is a rail hub of Switzerland. History Significant amounts of artefacts of the Magdalenian (c. 16'000 to 14'000 years ago) have been excavated near Olten. There are also finds dated to the Mesolithic and Neolithic, but there is no trace of a settlement, and no ceramic finds; finds dating to the Bronze and Iron Ages are also rather limited. There was a vicus at the site during the Roman era. The name of the settlement is not known, but it seems to have been of a certain importance, presumably reflecting the presence of a bridge across the Aar River. The Roman settlement was probably destroyed in the later 3rd century. At the end of the 3rd century, a fortification was built at the bridge-head, on the south-eastern corner of the earlier vicus.

Alpiq Group
Alpiq is a leading energy company in Switzerland and the largest energy service provider with focus on European markets. The company operates mainly in Switzerland, but it also has power stations in Italy, France, Norway, Hungary and the Czech Republic and building new ones in Germany, Italy, France, Bulgaria and the Czech Republic. The group was established in 2009 in Neuchâtel, Switzerland after the merger of two Swiss energy companies Aare-Tessin Ltd. for Electricity (Atel) and Energie Ouest Suisse (EOS). History Alpiq was founded in 2009 as a result of the merger of Swiss energy companies Atel and EOS. Atel (Aare-Tessin Ltd. for Electricity) was founded in 1894 and was active in Europe in the production, trading and sale of electricity. EOS (Energie Ouest Suisse) was founded in 1919 by several electricity companies based in Western Switzerland. The company was specialised in producing electric power from hydroelectric sources and owned many stations in the country. It also ha ...

Emergency Feedwater System
An emergency is an urgent, unexpected, and usually dangerous situation that poses an immediate risk to health, life, property, or environment and requires immediate action. Most emergencies require urgent intervention to prevent a worsening of the situation, although in some situations, mitigation may not be possible and agencies may only be able to offer palliative care for the aftermath. While some emergencies are self-evident (such as a natural disaster that threatens many lives), many smaller incidents require that an observer (or affected party) decide whether it qualifies as an emergency. The precise definition of an emergency, the agencies involved and the procedures used, vary by jurisdiction, and this is usually set by the government, whose agencies (emergency services) are responsible for emergency planning and management. Defining an emergency An incident, to be an emergency, conforms to one or more of the following, if it: * Poses an immediate threat to life, hea ...

High-pressure Injection Pump
In science and engineering the study of high pressure examines its effects on materials and the design and construction of devices, such as a diamond anvil cell, which can create high pressure. By ''high pressure'' is usually meant pressures of thousands (kilobars) or millions (megabars) of times atmospheric pressure (about 1 bar or 100,000 Pa). History and overview Percy Williams Bridgman received a Nobel Prize in 1946 for advancing this area of physics by several magnitudes of pressure (400 MPa to 40,000 MPa). The list of founding fathers of this field includes also the names of Harry George Drickamer, Tracy Hall, Francis P. Bundy, Leonid F. Vereschagin, and Sergey M. Stishov. It was by applying high pressure as well as high temperature to carbon that man-made diamonds were first produced as well as many other interesting discoveries. Almost any material when subjected to high pressure will compact itself into a denser form, for example, quartz, also called silica or silicon dio ...

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 ...

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 process heat and cool the working fluid to near the 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 air temperature using 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 draft and induced draft cooling towers. Cooling towers vary in size from small roof-top units to very large hyperboloid structures (as in the adjacent image) that can be up to tall and in diameter, or rectangu ...
