Nuclear Power Plant
A nuclear power plant (NPP) is a thermal power station in which the heat source is a nuclear reactor. As is typical of thermal power stations, heat is used to generate steam that drives a steam turbine connected to a generator that produces electricity. , the International Atomic Energy Agency reported there were 422 nuclear power reactors in operation in 32 countries around the world, and 57 nuclear power reactors under construction. Nuclear plants are very often used for base load since their operations, maintenance, and fuel costs are at the lower end of the spectrum of costs. However, building a nuclear power plant often spans five to ten years, which can accrue to significant financial costs, depending on how the initial investments are financed. Nuclear power plants have a carbon footprint comparable to that of renewable energy such as solar farms and wind farms, and much lower than fossil fuels such as natural gas and brown coal.

Central Maine Power
Avangrid, Inc. (formerly Energy East and Iberdrola USA), is an energy services and delivery company. AVANGRID serves about 3.1 million customers throughout New England, Pennsylvania and New York in the United States. History In 2008 Iberdrola S.A. purchased Energy East. Iberdrola renamed the company Iberdrola USA. In November 2010, Iberdrola USA sold its gas distribution companies in Connecticut and Massachusetts, the Southern Connecticut Gas Company, Connecticut Natural Gas Corporation, and the Berkshire Gas Company, to UIL Holdings Corporation. In 2012, Iberdrola USA sold its energy services companies, Energetix and NYSEG Solutions, to Direct Energy. In February 2015, Iberdrola USA announced that it had entered into a merger agreement with UIL Holdings Corporation under which UIL Holdings Corporation would merge into a subsidiary of Iberdrola USA, Inc. In December 2015, "Iberdrola USA finalized its acquisition of UIL Holdings ... to create a new company, AVANGRID, wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuclear Reactor
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 Nuclear medicine, medical and industrial radiography, 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 th ...

Westinghouse Electric (1886)
The Westinghouse Electric Corporation was an American manufacturing company founded in 1886 by George Westinghouse. It was originally named "Westinghouse Electric & Manufacturing Company" and was renamed "Westinghouse Electric Corporation" in 1945. The company acquired the CBS television network in 1995 and was renamed "CBS Corporation" until being acquired by Viacom in 1999, a merger completed in April 2000. The CBS Corporation name was later reused for one of the two companies resulting from the split of Viacom in 2006. The Westinghouse trademarks are owned by Westinghouse Electric Corporation, and were previously part of Westinghouse Licensing Corporation. The nuclear power business, Westinghouse Electric Company, was spun off from the Westinghouse Electric Corporation in 1999. History Westinghouse Electric was founded by George Westinghouse in Pittsburgh, Pennsylvania, on January 8, 1886. The firm became active in developing electric infrastructure throughou ...

Sears Island
Sears Island, known as Wassumkeag or shining beach by the indigenous Wabanaki tribes of northern New England, is located off the coast of Searsport in Waldo County, Maine, at the top of Penobscot Bay. The island is the largest undeveloped, uninhabited, causeway-accessible island on the eastern coast of the United States. It is in area. It is part of the Town of Searsport. History and geography It was named after David Sears of Boston after he agreed to grant a large sum of money towards founding of Searsport. Sears Island is state-owned land, but is part of the town of Searsport. It used to be known as Brigadier's Island. A causeway was built approximately 20 years ago upon what had been a tidal bar. At high tide Sears Island was a true island, and at low tide the exposed gravel bar allowed for easy access. Locals would drive over at low tide, always careful to return in time, lest they would have to wade or swim and leave the car stranded until the next tide. Several gen ...

Nuclear Power Debate
The nuclear power debate is a long-running controversy about the risks and benefits of using nuclear reactors to generate electricity for civilian purposes. The debate about nuclear power peaked during the 1970s and 1980s, as more and more reactors were built and came online, and "reached an intensity unprecedented in the history of technology controversies" in some countries. Thereafter, the nuclear industry created jobs, focused on safety, and public concerns mostly waned. In the 2010s, with growing public awareness about climate change and the critical role that carbon dioxide and methane emissions plays in causing the heating of the earth's atmosphere, there was a resurgence in the intensity of the nuclear power debate. Nuclear power advocates point to nuclear power's reliable, emission-free, high-density energy, alongside a generation of young physicists and engineers working to bring a new generation of nuclear technology into existence to replace fossil fuels.

List Of Canceled Nuclear Plants In The United States
This is a list of canceled nuclear reactors in the United States. History The late 1960s and early 1970s saw a rapid growth in the development of nuclear power in the United States. By 1976, however, many nuclear plant proposals were no longer viable due to a slower rate of growth in electricity demand, significant cost and time overruns, and more complex regulatory requirements. Also, there was considerable public opposition to nuclear power in the US by this time, which contributed to delays in licensing planned nuclear power stations, and further increased costs. By the end of the 1970s it became clear that nuclear power would not grow nearly as dramatically as once believed. This was particularly galvanized by the Three Mile Island accident in 1979. Eventually, more than 120 reactor orders were ultimately cancelled and the construction of new reactors ground to a halt. Al Gore has commented on the historical record and reliability of nuclear power in the United States: O ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
