Nuclear power plants are classified according to the type of reactor used. However some installations have several independent units, and these may use different classes of reactor. In addition, some of the plant-types below in the future may have passively safe features. Nuclear power plant - Fission reactors. Fission power reactors generate heat by nuclear fission of fissile isotopes of uranium and plutonium. They may be further divided into three classes: Thermal reactors use ...

The Vienna Convention on Civil Liability for Nuclear Damage puts in place an international framework for nuclear liability [3]. However states with a majority of the world's nuclear power plants, including the U.S., Russia, China and Japan, are not party to any international nuclear liability conventions. In the U.S., insurance for nuclear or radiological incidents is covered (for facilities licensed throu ...

The episodes Future-Drama and Lisa's Wedding reveal that the plant will eventually upgrade the number of cooling towers (and possibly reactors) from two to at least five, perhaps as a response to the future growth of Springfield. In Lisa's Wedding, set a decade in the future, we also discover that Lenny and Carl have been promoted to the executive board while Milhouse Van Houten has become a supervisor. The plant is operated mainly by robo ...

The 1976 controversy involved the Clamshell Alliance, an organization formed to protest the construction of the plant. Several small demonstrations at the site occurred in the lead-up to a massive occupation of Seabrook. More than 2,000 members of the Clamshell Alliance occupied the site in April, 1977. 1,414 of the activists were arrested and held for two weeks refusing bail. Opposition to the plant has been generally quiet since construc ...

Opponents of nuclear power claim that any of the environmental benefits are outweighed by safety compromises and by the costs related to construction and operation of nuclear power plants, including costs for spent-fuel disposition and plant retirement. Proponents of nuclear power state that nuclear energy is the only power source which explicitly factors the estimated costs for waste containment and plant decommissioning into its overall cost, and that the quoted cost of fossil fuel plants is deceptively low for this reason. The cost of some renewables would be increased too if they included necessary ...

Opponents of nuclear power, such as Greenpeace, argue against its use due to issues like the long term problems of storing radioactive waste, the potential for severe radioactive contamination by an accident, and the possibility that its use will lead to the proliferation of nuclear weapons. They point to the nuclear accidents. According to a 1978 finding by the Supreme Court of the United States, comprehensive testing and study had not yet removed the risk of a major nuclear accident [47]. In the 1980s and 1990s each US nuclear plant ...

Nuclear power - Origins. The first successful experiment with nuclear fission was conducted in 1938 in Berlin by the German physicists Otto Hahn, Lise Meitner and Fritz Strassman. During the Second World War, a number of nations embarked on crash programs to develop nuclear energy, focusing first on the development of nuclear reactors. The first self-sustaining nuclear chain reaction was obtained by Enrico Fermi on December 2nd,1942, and reactors based on his research were used to produce the plutonium nec ...

A Nuclear Reactor is only a small part of the life-cycle for nuclear power. The process starts with mining. Generally, uranium mines are either open-pit strip mines, or in-situ leach mines. In either case, the uranium ore is extracted, usually converted into a stable and compact form such as yellowcake, and then transported to a processing facility. At the reprocessing facility, the yellowcake is converted to uranium hexafluoride, which is then enriched using various techniques. At this point, the enriched uranium, containing more than the n ...

In 2005, there were 441 commercial nuclear generating units throughout the world, with a total capacity of about 368 gigawatts.[6] 111 reactors (36GW) have been shut down.[7] 80% of reactors (and of generating capacity) are more than 15 years old.[8] In 2004 in the United States, there were 104 (69 pressurized water reactors and 35 boiling water reactors) commercial nuclear generating units licensed to operate, producing a total of 97,400 megawatts (electric), which is approximately 20 percent of the nation's total electric energy con ...

Nuclear reactors require water to keep the reactor cool. The process of extracting energy from a heat source, called the Rankine cycle, requires the steam to be cooled down. Rivers are the most common source of cooling water, as well as the destination for waste heat. The temperature of exhaust water must be regulated to avoid killing fish; long-term impact of hotter-than-natural water on ecosystems is an environmental concern. The need to regulate exhaust temperature also limits generation capacity. On extremely hot days, which is wh ...

Some experts predict that electricity shortages, fossil fuel price increases and concern over Greenhouse gas emissions will renew the demand for nuclear power plants. Watts Bar 1, which came on-line in 1997, was the last U.S. commercial nuclear reactor to go on-line. As of 2004, the immediate future of the industry in many countries still appeared uncertain, the most notable exceptions being Japan, China and India, all actively developing both fast and thermal technology, South Korea and the United States, developing thermal technolog ...
