Catawba Nuclear Station
The Catawba Nuclear Station is a nuclear power plant located on a peninsula, called "Concord Peninsula", that reaches out into Lake Wylie, in York, South Carolina, USA. Catawba utilizes a pair of Westinghouse four-loop pressurized water reactors. As a part of the Megatons to Megawatts Program Catawba was one of the plants that received and tested 4 fuel assemblies containing MOX fuel with the plutonium supplied from old weapons programs. Because concerns of nuclear proliferation are greater with fuel containing plutonium, special precautions and added security were used around the new fuel. The four test assemblies did not perform as expected and at present those plans are shelved. History In 2005, Catawba Nuclear Station's Unit 1 was selected to test four fuel assemblies containing mixed oxide (MOX) fuel, incorporating 140 kg of plutonium supplied from recycled nuclear weapons material. The MOX fuel pellets were supplied by the Cadarache reprocessing facilitiy, and p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
York, South Carolina
York is a city in and county seat of York County, South Carolina, United States. The population was approximately 6,985 at the 2000 census and up to 7,736 at the 2010 census. York is located approximately southwest of Charlotte, North Carolina and west of Rock Hill, South Carolina. History The first European settlers came to York in the early 1750s, having migrated south from Pennsylvania and Virginia. Of the three major groups settling Pennsylvania, the English came first, then the Germans, and then the Scots. The county names of Lancashire, Cheshire and Yorkshire had been brought from England to Pennsylvania, and then on to South Carolina by the early settlers. Prior to this, the first known inhabitants of York County were the Catawba Indians. The town of York was originally known as Fergus's Crossroads for a tavern, owned by two brothers, William and John Fergus, that was located at the intersection of the road from Rutherfordton to Camden and the road from Charl ...

Plutonium Management And Disposition Agreement
The Plutonium Management and Disposition Agreement is an agreement between the United States and Russia signed in 2000, wherein both nations agreed to dispose of significant fractions of their "excess" (beyond what they need for their nuclear weapons) weapons-grade plutonium. An amended version was signed in April 2010 and went into effect in July 2011. The US has about 90 tons of weapons-capable plutonium, while Russia has 128 tons. The US declared 60 tons as excess, while Russia declared 50 tons excess. The two sides agreed that each would eliminate 34 tons. The agreement regulates the conversion of non-essential plutonium into mixed oxide (MOX) fuel used to produce electricity. Both sides were required to render 34 tons of weapons grade plutonium, into reactor grade plutonium alongside reaching the ''spent fuel standard'', that is mixed with the other more highly irradiating products within spent fuel. In 2007, the US began constructing the Mixed Oxide Fuel Fabrication F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tritium
Tritium ( or , ) or hydrogen-3 (symbol T or H) is a rare and radioactive isotope of hydrogen with half-life about 12 years. The nucleus of tritium (t, sometimes called a ''triton'') contains one proton and two neutrons, whereas the nucleus of the common isotope hydrogen-1 (''protium'') contains one proton and zero neutrons, and that of hydrogen-2 (''deuterium'') contains one proton and one neutron. Naturally occurring tritium is extremely rare on Earth. The atmosphere has only trace amounts, formed by the interaction of its gases with cosmic rays. It can be produced artificially by irradiating lithium metal or lithium-bearing ceramic pebbles in a nuclear reactor and is a low-abundance byproduct in normal operations of nuclear reactors. Tritium is used as the energy source in radioluminescent lights for watches, gun sights, numerous instruments and tools, and even novelty items such as self-illuminating key chains. It is used in a medical and scientific setting as a radioacti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

2010 United States Census
The United States census of 2010 was the twenty-third United States national census. National Census Day, the reference day used for the census, was April 1, 2010. The census was taken via mail-in citizen self-reporting, with enumerators serving to spot-check randomly selected neighborhoods and communities. As part of a drive to increase the count's accuracy, 635,000 temporary enumerators were hired. The population of the United States was counted as 308,745,538, a 9.7% increase from the 2000 census. This was the first census in which all states recorded a population of over half a million people as well as the first in which all 100 largest cities recorded populations of over 200,000. Introduction As required by the United States Constitution, the U.S. census has been conducted every 10 years since 1790. The 2000 U.S. census was the previous census completed.

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 or a ...

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 e ...

Kilowatt-hour
A kilowatt-hour ( unit symbol: kW⋅h or kW h; commonly written as kWh) is a unit of energy: one kilowatt of power for one hour. In terms of SI derived units with special names, it equals 3.6 megajoules (MJ). Kilowatt-hours are a common billing unit for electrical energy delivered to consumers by electric utilities. Definition The kilowatt-hour is a composite unit of energy equal to one kilowatt (kW) sustained for (multiplied by) one hour. Expressed in the standard unit of energy in the International System of Units (SI), the joule (symbol J), it is equal to 3,600 kilojoules or 3.6 MJ."Half-high dots or spaces are used to express a derived unit formed from two or more other units by multiplication.", Barry N. Taylor. (2001 ed.''The International System of Units.'' (Special publication 330). Gaithersburg, MD: National Institute of Standards and Technology. 20.
