GE BWR
General Electric's BWR product line of boiling water reactors represents the designs of a relatively large (~18%) percentage of the commercial fission reactors around the world. The progenitor of the BWR line was the 5 MW Vallecitos Boiling Water Reactor (VBWR), brought online in October 1957. Six design iterations, BWR-1 through BWR-6, were introduced between 1955 and 1972. This was followed by the Advanced Boiling Water Reactor (ABWR) introduced in the 1990s and the Economic Simplified Boiling Water Reactor (ESBWR) introduced in the early 2010s. As of August 2018, 83 reactors of this design family have been built, of which 67 reactors are operational. The design garnered world attention in the aftermath of the INES level 7 Fukushima Daiichi nuclear disaster of 11 March 2011. GE had been a major contractor to the Fukushima Daiichi Nuclear Power Plant in Japan, which consisted of six boiling water reactors of GE design. The reactors for Units 1, 2, and 6 were supplied by Ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
General Electric
General Electric Company (GE) is an American multinational conglomerate founded in 1892, and incorporated in New York state and headquartered in Boston. The company operated in sectors including healthcare, aviation, power, renewable energy, digital industry, additive manufacturing and venture capital and finance, but has since divested from several areas, now primarily consisting of the first four segments. In 2020, GE ranked among the Fortune 500 as the 33rd largest firm in the United States by gross revenue. In 2011, GE ranked among the Fortune 20 as the 14th most profitable company, but later very severely underperformed the market (by about 75%) as its profitability collapsed. Two employees of GE – Irving Langmuir (1932) and Ivar Giaever (1973) – have been awarded the Nobel Prize. On November 9, 2021, the company announced it would divide itself into three investment-grade public companies. On July 18, 2022, GE unveiled the brand names of the companies it will ...

Big Rock Point Nuclear Power Plant
Big Rock Point was a nuclear power plant near Charlevoix, Michigan, United States. Big Rock operated from 1962 to 1997. It was owned and operated by Consumers Power, now known as Consumers Energy. Its boiling water reactor was made by General Electric (GE) and was capable of producing 67 megawatts of electricity. Bechtel Corporation was the primary contractor. History Big Rock was Michigan's first nuclear power plant and the nation's fifth. It also produced cobalt-60 for the medical industry from 1971 to 1982. Ground was broken on July 20, 1960. Construction was completed in 29 months at a cost of $27.7 million. Its license from the United States Atomic Energy Commission, Nuclear Regulatory Commission was issued on August 29, 1962. The reactor first went critical on September 27 and the first electricity was generated on December 8, 1962. A promotional video for the plant featured then GE spokesman Ronald Reagan.

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] |
BWR Mark I Containment, Diagram
A boiling water reactor (BWR) is a type of light water nuclear reactor used for the generation of electrical power. It is a design different from a Soviet graphite-moderated RBMK. It is the second most common type of electricity-generating nuclear reactor after the pressurized water reactor (PWR), which is also a type of light water nuclear reactor. The main difference between a BWR and PWR is that in a BWR, the reactor core heats water, which turns to steam and then drives a steam turbine. In a PWR, the reactor core heats water, which does not boil. This hot water then exchanges heat with a lower pressure system, which turns water into steam that drives the turbine. The BWR was developed by the Argonne National Laboratory and General Electric (GE) in the mid-1950s. The main present manufacturer is GE Hitachi Nuclear Energy, which specializes in the design and construction of this type of reactor. Overview A boiling water reactor uses demineralized water as a coolant and neu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clinton Nuclear Generating Station
The Clinton Power Station is a nuclear power plant located near Clinton, Illinois, USA. The power station began commercial operation on November 24, 1987 and has a nominal net electric output of 1062 MWe. Due to inflation and cost overruns, Clinton's final construction cost was $4.25 billion ($ today), nearly 1,000% over the original budget of $430 million and seven years behind schedule. The station has a single generation II General Electric Boiling Water Reactor. The present reactor operating license was issued April 17, 1987, and will expire September 29, 2026. Plans for a second reactor were shelved. Exelon, the former owner and operator of the present reactor, announced plans to permanently close the power station in June 2017, due to the plants struggles to compete economically in wholesale markets, resulting in a loss of millions of dollars in recent years.Dianne CardwelExelon to Close 2 Nuclear Plants in Illinois June 2, 2016.

LaSalle County Nuclear Generating Station
LaSalle County Nuclear Generating Station, located in Brookfield Township, LaSalle County, Illinois, near Marseilles, southeast of Ottawa, serves Chicago and Northern Illinois with electricity. The plant is owned and operated by Constellation Energy following separation from Exelon Corporation in 2022. Its Units 1 and 2 began commercial operation in October 1982, and October 1984, respectively. It has two General Electric boiling water reactors. LaSalle's Unit 1 and Unit 2 together produce 2,320 megawatts, which is enough electricity for the needs of 2.3 million American homes. Instead of cooling towers, the station has a man-made cooling lake, which is also a popular fishery — LaSalle Lake State Fish and Wildlife Area — managed by the Illinois Department of Natural Resources.

Browns Ferry Nuclear Power Plant
The Browns Ferry Nuclear Plant is located on the Tennessee River near Decatur and Athens, Alabama, on the north side (right bank) of Wheeler Lake. The site has three General Electric boiling water reactor (BWR) nuclear generating units and is owned entirely by the Tennessee Valley Authority (TVA). With a generating capacity of nearly 3.8 gigawatts, it is the second most powerful nuclear plant in the United States, behind the Palo Verde Nuclear Generating Station in Arizona, and the most powerful generating station operated by TVA. History The nuclear power plant is named after a ferry that operated at the site until the middle of the 20th century. Browns Ferry was TVA's first nuclear power plant; its approval occurred on June 17, 1966 and construction began in September 1966. In 1974, the time of its initial operation, it was the largest nuclear plant in the world. It was the first nuclear plant in the world to use units capable of generating more than 1 gigawatt of power. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
