Nuclear Technology In The United States
Nuclear power in the United States is provided by 92 commercial reactors with a net capacity of 94.7 gigawatts (GW), with 61 pressurized water reactors and 31 boiling water reactors. In 2019, they produced a total of 809.41 terawatt-hours of electricity, which accounted for 20% of the nation's total electric energy generation. In 2018, nuclear comprised nearly 50 percent of US emission-free energy generation. , there are two new reactors under construction with a gross electrical capacity of 2,500 MW, while 39 reactors have been permanently shut down. The United States is the world's largest producer of commercial nuclear power, and in 2013 generated 33% of the world's nuclear electricity. With the past and future scheduled plant closings, China and Russia could surpass the United States in nuclear energy production. As of October 2014, the Nuclear Regulatory Commission (NRC) has granted license renewals providing 20-year extensions to a total of 74 reactors. In early 2014, th ...

Kewaunee Power Station
The Kewaunee Power Station is a decommissioned nuclear power plant, located on a plot in the town of Carlton, Wisconsin, southeast of Green Bay, Wisconsin in Kewaunee County, and south of the city of Kewaunee. KPS was the third nuclear power plant built in Wisconsin, and the 44th built in the United States. Due to falling electricity prices resulting from the falling price of natural gas, the plant ceased operation May 7, 2013. In 2022, a sale of the plant was approved by the federal government.Sale of former Kewaunee nuclear plant approved by Brian Kerhin, ''Fox 11 News'', ''March 31, 2022'' This was controversial because the sale affects what will be done with the trust money previously saved for the decommissioning, and who is responsible for any cos ...

United States Atomic Energy Commission
The United States Atomic Energy Commission (AEC) was an agency of the United States government established after World War II by U.S. Congress to foster and control the peacetime development of atomic science and technology. President Harry S. Truman signed the McMahon/Atomic Energy Act on August 1, 1946, transferring the control of atomic energy from military to civilian hands, effective on January 1, 1947. This shift gave the members of the AEC complete control of the plants, laboratories, equipment, and personnel assembled during the war to produce the atomic bomb. An increasing number of critics during the 1960s charged that the AEC's regulations were insufficiently rigorous in several important areas, including radiation protection standards, nuclear reactor safety, plant siting, and environmental protection. By 1974, the AEC's regulatory programs had come under such strong attack that the U.S. Congress decided to abolish the AEC. The AEC was abolished by the Ener ...

Shippingport Reactor
The Shippingport Atomic Power Station was (according to the US Nuclear Regulatory Commission) the world's first full-scale atomic electric power plant devoted exclusively to peacetime uses.Though Obninsk Nuclear Power Plant was connected to the Moscow Grid in 1954 and was the first nuclear reactor that produced commercial electricity, it can still be considered a small scale station designed principally to carry out nuclear experiments. The first British Magnox reactor at Calder Hall was connected to the grid on 27 August 1956, its primary purpose was to produce plutonium for military uses.The Vallecitos Nuclear Center started producing electric power in October 1957, but it served as a test or pilot plant. It was located near the present-day Beaver Valley Nuclear Generating Station on the Ohio River in Beaver County, Pennsylvania, United States, about 25 miles (40 km) from Pittsburgh. The reactor reached criticality on December 2, 1957, and aside from stoppages for three ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fukushima Daiichi Nuclear Disaster
The was a nuclear accident in 2011 at the Fukushima Daiichi Nuclear Power Plant in Ōkuma, Fukushima, Japan. The proximate cause of the disaster was the 2011 Tōhoku earthquake and tsunami, which occurred on the afternoon of 11 March 2011 and remains the most powerful earthquake ever recorded in Japan. The earthquake triggered a powerful tsunami, with 13–14-meter-high waves damaging the nuclear power plant's emergency diesel generators, leading to a loss of electric power. The result was the most severe nuclear accident since the Chernobyl disaster in 1986, classified as level seven on the International Nuclear Event Scale (INES) after initially being classified as level five, and thus joining Chernobyl as the only other accident to receive such classification. While the 1957 explosion at the Mayak facility was the second worst by radioactivity released, the INES ranks incidents by impact on population, so Chernobyl (335,000 people evacuated) and Fukushima (154,000 evacuate ...

Nuclear Power 2010 Program
The "Nuclear Power 2010 Program" was launched in 2002 by President George W. Bush in 2002, 13 months after the beginning of his presidency, in order to restart orders for nuclear power reactors in the U.S. by providing subsidies for a handful of Generation III+ demonstration plants. The expectation was that these plants would come online by 2010, but it was not met. In March 2017, the leading nuclear-plant maker, Westinghouse Electric Company, filed for bankruptcy due to losing over $9 billion in construction losses from working on two nuclear plants. This loss was partly caused by safety concerns due to the Fukushima disaster, Germany's Energiewende, the growth of solar and wind power, and low natural gas prices. Overview The "Nuclear Power 2010 Program" was unveiled by the U.S. Secretary of Energy Spencer Abraham on February 14, 2002 as one means towards addressing the expected need for new power plants. The program was a joint government/industry cost-shared effort to ident ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuclear Renaissance
Since about 2001 the term nuclear renaissance has been used to refer to a possible nuclear power industry revival, driven by rising fossil fuel prices and new concerns about meeting greenhouse gas emission limits. In the 2009 ''World Energy Outlook'', the International Energy Agency stated that: A nuclear renaissance is possible but cannot occur overnight. Nuclear projects face significant hurdles, including extended construction periods and related risks, long licensing processes and manpower shortages, plus long‐standing issues related to waste disposal, proliferation and local opposition. The financing of new nuclear power plants, especially in liberalized markets, has always been difficult and the financial crisis seems almost certain to have made it even more so. The huge capital requirements, combined with risks of cost overruns and regulatory uncertainties, make investors and lenders very cautious, even when demand growth is robust.International Energy Agency, ''Wor ...

Cost Overrun
A cost overrun, also known as a cost increase or budget overrun, involves unexpected incurred costs. When these costs are in excess of budgeted amounts due to a value engineering underestimation of the actual cost during budgeting, they are known by these terms. Cost overruns are common in infrastructure, building, and technology projects. For IT projects, a 2004 industry study by the Standish Group found an average cost overrun of 43 percent; 71 percent of projects came in over budget, exceeded time estimates, and had estimated too narrow a scope; and total waste was estimated at $55 billion per year in the US alone. Many major construction projects have incurred cost overruns; cost estimates used to decide whether important transportation infrastructure should be built can mislead grossly and systematically. Cost overrun is distinguished from cost escalation, which is an ''anticipated'' growth in a budgeted cost due to factors such as inflation. Causes Recent works by Ahia ...
