Pilgrim Nuclear Generating Station
Pilgrim Nuclear Power Station (PNPS) is a decommissioned nuclear power plant in Massachusetts in the Manomet section of Plymouth on Cape Cod Bay, south of the tip of Rocky Point and north of Priscilla Beach. Like many similar plants, it was constructed by Bechtel, and was powered by a General Electric BWR 3 boiling water reactor inside of a Mark 1 pressure suppression type containment and generator. With a 690 MW production capacity, it produced about 14% of the electricity generated in Massachusetts. On October 13, 2015, the plant's owners announced that it would close by June 1, 2019, citing "market conditions and increased costs," which would have included tens of millions of dollars of necessary safety upgrades. History Built at a cost of $231 million in 1972 by Boston Edison, the plant was sold in 1999 to the Louisiana-based Entergy Corporation, part of a complex deal that was the result of deregulation of the electrical utility industry. On April 11, 1986, a rec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plymouth, Massachusetts
Plymouth (; historically known as Plimouth and Plimoth) is a town in Plymouth County, Massachusetts, United States. Located in Greater Boston, the town holds a place of great prominence in American history, folklore, and culture, and is known as "America's Hometown". Plymouth was the site of the colony founded in 1620 by the ''Mayflower'' Pilgrims, where New England was first established. It is the oldest municipality in New England and one of the oldest in the United States. The town has served as the location of several prominent events, one of the more notable being the First Thanksgiving feast. Plymouth served as the capital of Plymouth Colony from its founding in 1620 until the colony's merger with the Massachusetts Bay Colony in 1691. The English explorer John Smith named the area Plymouth (after the city in South West England) and the region 'New England' during his voyage of 1614 (the accompanying map was published in 1616). It was a later coincidence that, after an ab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NSTAR (company)
NSTAR was a utility company that provided retail electricity and natural gas to 1.4 million customers in eastern and central Massachusetts, including the Boston urban area. NSTAR became a subsidiary of Northeast Utilities in April 2012. In February 2015, Northeast Utilities and all of its operating companies (Western Massachusetts Electric, Public Service New Hampshire, Connecticut Light and Power, Yankee Gas, and NSTAR Gas and Electric) became one large company known as Eversource Energy. NSTAR was formed in 1999 by the merger of BEC Energy and Commonwealth Energy System and had the following operating units: Boston Edison Company, Cambridge Electric Light Company, Commonwealth Electric Company, and NSTAR Gas Company (formerly Commonwealth Gas and Cambridge Gas Company). As a part of deregulation of the local electrical power industry, NSTAR has divested itself of all electric generation facilities, keeping only those elements of the business which remain regulated. NSTAR sold ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forage Fish
Forage fish, also called prey fish or bait fish, are small pelagic fish which are preyed on by larger predators for food. Predators include other larger fish, seabirds and marine mammals. Typical ocean forage fish feed near the base of the food chain on plankton, often by Filter feeder, filter feeding. They include particularly fishes of the order Clupeiformes (herrings, sardines, shad, hilsa, menhaden, anchovies, and sprats), but also other small fish, including halfbeaks, Atheriniformes, silversides, Smelt (fish), smelt such as capelin and goldband fusiliers. Forage fish compensate for their small size by forming Shoaling and schooling, schools. Some swim in synchronised grids with their mouths open so they can efficiently filter plankton. These schools can become immense Shoaling and schooling, shoals which move along coastlines and Fish migration, migrate across open oceans. The shoals are concentrated energy resources for the great marine predators. The predators are keenly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radioactive Contamination
Radioactive contamination, also called radiological pollution, is the deposition of, or presence of radioactive substances on surfaces or within solids, liquids, or gases (including the human body), where their presence is unintended or undesirable (from the International Atomic Energy Agency (IAEA) definition). Such contamination presents a hazard because the radioactive decay of the contaminants, produces ionizing radiation (namely alpha, beta, gamma rays and free neutrons). The degree of hazard is determined by the concentration of the contaminants, the energy of the radiation being emitted, the type of radiation, and the proximity of the contamination to organs of the body. It is important to be clear that the contamination gives rise to the radiation hazard, and the terms "radiation" and "contamination" are not interchangeable. The sources of radioactive pollution can be classified into two groups: natural and man-made. Following an atmospheric nuclear weapon discharge ...

Boston Marathon Bombing
The Boston Marathon bombing was a domestic terrorist attack that took place during the annual Boston Marathon on April 15, 2013. Two terrorists, brothers Dzhokhar Tsarnaev and Tamerlan Tsarnaev, planted two homemade pressure cooker bombs, which detonated 14 seconds and apart at 2:49p.m., near the finish line of the race, killing three people and injuring hundreds of others, including 17 who lost limbs. Three days later, on April 18, Federal Bureau of Investigation (FBI) released images of two suspects. They were later identified as the Tsarnaev brothers, who were Chechen Kyrgyzstani-Americans. Following their identification, at 10:35p.m., they killed an MIT policeman. At 11:00p.m., they kidnapped a man in his car. At 12:15a.m., on April 19, the man escaped. At 12:45a.m., they had a shootout with the police in nearby Watertown, during which two officers were severely injured (one of whom, DJ Simmonds, died a year later). Tamerlan was shot several times, and his brother Dz ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Anti-nuclear Groups In The United States
More than 80 anti-nuclear groups are operating, or have operated, in the United States. These include Abalone Alliance, Clamshell Alliance, Greenpeace USA, Institute for Energy and Environmental Research, Musicians United for Safe Energy, Nevada Desert Experience, Nuclear Control Institute, Nuclear Information and Resource Service, Public Citizen Energy Program, Shad Alliance, and the Sierra Club. These are direct action, environmental, health, and public interest organizations who oppose nuclear weapons and/or nuclear power. In 1992, the chairman of the Nuclear Regulatory Commission said that "his agency had been pushed in the right direction on safety issues because of the pleas and protests of nuclear watchdog groups". Some of the most influential groups in the anti-nuclear movement have had members who included Nobel Laureates (e.g., Linus Pauling and Hermann Joseph Muller). These scientists have belonged primarily to two groups: the Federation of American Scientists, and t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Yucca Mountain Nuclear Waste Repository
The Yucca Mountain Nuclear Waste Repository, as designated by the Nuclear Waste Policy Act amendments of 1987, is a proposed deep geological repository storage facility within Yucca Mountain for spent nuclear fuel and other high-level radioactive waste in the United States. The site is on federal land adjacent to the Nevada Test Site in Nye County, Nevada, about northwest of the Las Vegas Valley. The project was approved in 2002 by the 107th United States Congress, but the 112th Congress ended federal funding for the site via amendment to the Department of Defense and Full-Year Continuing Appropriations Act, passed on April 14, 2011, during the Obama Administration. The project has encountered many difficulties and was highly contested by the public, the Western Shoshone peoples, and many politicians. The project also faces strong state and regional opposition. The Government Accountability Office stated that the closure was for political, not technical or safety reasons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spent Nuclear Fuel
Spent nuclear fuel, occasionally called used nuclear fuel, is nuclear fuel that has been irradiated in a nuclear reactor (usually at a nuclear power plant). It is no longer useful in sustaining a nuclear reaction in an ordinary thermal reactor and depending on its point along the nuclear fuel cycle, it may have considerably different isotopic constituents. The term "fuel" is slightly confusing, as it implies a combustion of some type, which does not occur in a nuclear power plant. Nevertheless, this term is generally accepted. Nature of spent fuel Nanomaterial properties In the oxide fuel, intense temperature gradients exist that cause fission products to migrate. The zirconium tends to move to the centre of the fuel pellet where the temperature is highest, while the lower-boiling fission products move to the edge of the pellet. The pellet is likely to contain many small bubble-like pores that form during use; the fission product xenon migrates to these voids. Some of this xeno ...

Nuclear Regulatory Commission
The Nuclear Regulatory Commission (NRC) is an independent agency of the United States government tasked with protecting public health and safety related to nuclear energy. Established by the Energy Reorganization Act of 1974, the NRC began operations on January 19, 1975, as one of two successor agencies to the United States Atomic Energy Commission. Its functions include overseeing reactor safety and security, administering reactor licensing and renewal, licensing radioactive materials, radionuclide safety, and managing the storage, security, recycling, and disposal of spent fuel. History Prior to 1975 the Atomic Energy Commission was in charge of matters regarding radionuclides. The AEC was dissolved, because it was perceived as unduly favoring the industry it was charged with regulating.John Byrne and Steven M. Hoffman (1996). ''Governing the Atom: The Politics of Risk'', Transaction Publishers, p. 163. The NRC was formed as an independent commission to oversee nuclear ene ...
