Neckarwestheim Nuclear Power Plant
Neckarwestheim Nuclear Power Station is a nuclear power plant in Neckarwestheim, Germany, sometimes abbreviated GKN (for german: Gemeinschaftskraftwerk Neckar), operated by EnBW Kernkraft GmbH, a subsidiary of EnBW. 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 which produced traction current. Block I was shut down on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Traction Current Converter Plant
A traction substation, traction current converter plant, rectifier station or traction power substation (TPSS) is an electrical substation that converts electric power from the form provided by the electrical power industry for public utility service to an appropriate voltage, current type and frequency to supply railways, trams (streetcars) or trolleybuses with traction current. Conversions These systems can be used to convert three-phase 50 Hz or 60 Hz alternating current (AC) for the supply of AC railway electrification systems at a lower frequency and single phase, as used by many older systems, or to rectify AC into direct current (DC) for those systems (primarily public transit systems) using DC for traction power. The three-phase voltage from the local utility is stepped down and rectified in the traction substations to provide the required DC voltage. Equipment Rotating Originally, the conversion equipment usually consisted of one or more motor-generator sets contain ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Managing Director
A chief executive officer (CEO), also known as a central executive officer (CEO), chief administrator officer (CAO) or just chief executive (CE), is one of a number of corporate executives charged with the management of an organization especially an independent legal entity such as a company or nonprofit institution. CEOs find roles in a range of organizations, including public and private corporations, non-profit organizations and even some government organizations (notably state-owned enterprises). The CEO of a corporation or company typically reports to the board of directors and is charged with maximizing the value of the business, which may include maximizing the share price, market share, revenues or another element. In the non-profit and government sector, CEOs typically aim at achieving outcomes related to the organization's mission, usually provided by legislation. CEOs are also frequently assigned the role of main manager of the organization and the highest-ranking offic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Becquerel
The becquerel (; symbol: Bq) is the unit of radioactivity in the International System of Units (SI). One becquerel is defined as the activity of a quantity of radioactive material in which one nucleus decays per second. For applications relating to human health this is a small quantity, and SI multiples of the unit are commonly used. The becquerel is named after Henri Becquerel, who shared a Nobel Prize in Physics with Pierre and Marie Skłodowska Curie in 1903 for their work in discovering radioactivity. Definition 1 Bq = 1 s−1 A special name was introduced for the reciprocal second (s−1) to represent radioactivity to avoid potentially dangerous mistakes with prefixes. For example, 1 µs−1 would mean 106 disintegrations per second: 1·(10−6 s)−1 = 106 s−1, whereas 1 µBq would mean 1 disintegration per 1 million seconds. Other names considered were hertz (Hz), a special name already in use for the reciprocal second, and Fourier ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuclear Reactor Technology
A nuclear reactor is a device used to initiate and control a fission nuclear chain reaction or nuclear fusion reactions. Nuclear reactors are used at nuclear power plants for electricity generation and in nuclear marine propulsion. Heat from nuclear fission is passed to a working fluid (water or gas), which in turn runs through steam turbines. These either drive a ship's propellers or turn electrical generators' shafts. Nuclear generated steam in principle can be used for industrial process heat or for district heating. Some reactors are used to produce isotopes for medical and industrial use, or for production of weapons-grade plutonium. , the International Atomic Energy Agency reports there are 422 nuclear power reactors and 223 nuclear research reactors in operation around the world. In the early era of nuclear reactors (1940s), a reactor was known as a nuclear pile or atomic pile (so-called because the graphite moderator blocks of the first reactor were placed into a tall pi ...

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 ...

Containment Building
A containment building is a reinforced steel, concrete or lead structure enclosing a nuclear reactor. It is designed, in any emergency, to contain the escape of radioactive steam or gas to a maximum pressure in the range of . The containment is the fourth and final barrier to radioactive release (part of a nuclear reactor's defence in depth strategy), the first being the fuel ceramic itself, the second being the metal fuel cladding tubes, the third being the reactor vessel and coolant system. Each nuclear plant in the US is designed to withstand certain conditions which are spelled out as "Design Basis Accidents" in the Final Safety Analysis Report (FSAR). The FSAR is available for public viewing, usually at a public library near the nuclear plant. The containment building itself is typically an airtight steel structure enclosing the reactor normally sealed off from the outside atmosphere. The steel is either free-standing or attached to the concrete missile shield. In the U ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ABB Group
ABB Ltd. is a Swedish-Swiss multinational corporation headquartered in Zürich, Switzerland. The company was formed in 1988 when Sweden's Allmänna Svenska Elektriska Aktiebolaget (ASEA) and Switzerland's Brown, Boveri & Cie merged to create ASEA Brown Boveri, later simplified to the initials ABB. Both companies were established in the late 1800s and were major electrical equipment manufacturers, a business that ABB remains active in today. The company has also since expanded to robotics and automation technology. It is ranked 341st in the Fortune Global 500 list of 2018 and has been a global Fortune 500 company for 24 years. Until the sale of its Power Grids division in 2020, ABB was Switzerland's largest industrial employer. ABB is traded on the SIX Swiss Exchange in Zürich, Nasdaq Stockholm in Sweden, and the New York Stock Exchange in the United States. An ABB entity plead guilty for bid rigging in 2001, and the company has had 3 US Foreign Corrupt Practices Act bribin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
