Uranium is a chemical element; it has symbol U and atomic number 92. It is a silvery-grey metal in the actinide series of the periodic table. A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons. Uranium radioactively decays by emitting an alpha particle. The half-life of this decay varies between 159,200 and 4.5 billion years for different isotopes, making them useful for dating the age of the Earth. The most common isotopes in natural uranium are uranium-238 and uranium-235. Uranium has the highest atomic weight of the primordially occurring elements. Its density is about 70% higher than that of lead and slightly lower than that of gold or tungsten. It occurs naturally in low concentrations of a few parts per million in soil, rock and water, and is commercially extracted from uranium-bearing minerals such as uraninite.
Enriched uranium is a type of uranium in which the percent composition of uranium-235 has been increased through the process of isotope separation. Naturally occurring uranium is composed of three major isotopes: uranium-238, uranium-235, and uranium-234. 235U is the only nuclide existing in nature that is fissile with thermal neutrons.
Yellowcake is a type of uranium concentrate powder obtained from leach solutions, in an intermediate step in the processing of uranium ores. It is a step in the processing of uranium after it has been mined but before fuel fabrication or uranium enrichment. Yellowcake concentrates are prepared by various extraction and refining methods, depending on the types of ores. Typically, yellowcakes are obtained through the milling and chemical processing of uranium ore, forming a coarse powder that has a pungent odor, is insoluble in water, and contains about 80% uranium oxide, which melts at approximately 2880 °C.
Nuclear marine propulsion is propulsion of a ship or submarine with heat provided by a nuclear reactor. The power plant heats water to produce steam for a turbine used to turn the ship's propeller through a gearbox or through an electric generator and motor. Nuclear propulsion is used primarily within naval warships such as nuclear submarines and supercarriers. A small number of experimental civil nuclear ships have been built.
Arlit is an industrial town and capital of the Arlit Department of the Agadez Region of northern-central Niger, built between the Sahara Desert and the eastern edge of the Aïr Mountains. It is 200 kilometers south by road from the border with Algeria. As of 2011, the commune had a total population of 112,432 people.
The Union Minière du Haut-Katanga was a Belgian mining company which controlled and operated the mining industry in the copperbelt region in the modern-day Democratic Republic of the Congo between 1906 and 1966.
Orano Cycle, formerly COGEMA and Areva NC, is a French nuclear fuel company. It is the main subsidiary of Orano S.A. It is an industrial group active in all stages of the uranium fuel cycle, including uranium mining, conversion, enrichment, spent fuel reprocessing, and recycling.
The National Atomic Energy Commission is the Argentine government agency in charge of nuclear energy research and development.
Shinkolobwe, or Kasolo, or Chinkolobew, or Shainkolobwe, was a radium and uranium mine in the Haut-Katanga Province of the Democratic Republic of the Congo (DRC), located 20 km (12.4 mi) west of Likasi, 20 km (12.4 mi) south of Kambove, and about 145 km (90.1 mi) northwest of Lubumbashi.
Operation Opera, also known as Operation Babylon, was a surprise airstrike conducted by the Israeli Air Force on 7 June 1981, which destroyed an unfinished Iraqi nuclear reactor located 17 kilometres southeast of Baghdad, Iraq. The Israeli operation came a year after the Islamic Republic of Iran Air Force had caused minor damage to the same nuclear facility in Operation Scorch Sword, with the damage having been subsequently repaired by French technicians. Operation Opera, and related Israeli government statements following it, established the Begin Doctrine, which explicitly stated the strike was not an anomaly, but instead "a precedent for every future government in Israel". Israel's counter-proliferation preventive strike added another dimension to its existing policy of deliberate ambiguity, as it related to the nuclear weapons capability of other states in the region.
The uranium market, like all commodity markets, has a history of volatility, moving with the standard forces of supply and demand as well as geopolitical pressures. It has also evolved particularities of its own in response to the unique nature and use of uranium.
Argentina has a history with the development of weapons of mass destruction. Under the military dictatorship, Argentina began a nuclear weapons program in the early 1980s, but this was abolished when democracy was restored in 1983.
Uranium mining is the process of extraction of uranium ore from the ground. Over 50 thousand tons of uranium were produced in 2019. Kazakhstan, Canada, and Australia were the top three uranium producers, respectively, and together account for 68% of world production. Other countries producing more than 1,000 tons per year included Namibia, Niger, Russia, Uzbekistan, the United States, and China. Nearly all of the world's mined uranium is used to power nuclear power plants. Historically uranium was also used in applications such as uranium glass or ferrouranium but those applications have declined due to the radioactivity of uranium and are nowadays mostly supplied with a plentiful cheap supply of depleted uranium which is also used in uranium ammunition. In addition to being cheaper, depleted uranium is also less radioactive due to a lower content of short-lived 234
U and 235
U than natural uranium.
The Shimon Peres Negev Nuclear Research Center is an Israeli nuclear installation located in the Negev desert, about thirteen kilometers south-east of the city of Dimona.
This is the timeline of the nuclear program of Iran.
The State of Israel is widely believed to possess nuclear weapons. Estimates of Israel's stockpile range between 80 and 400 nuclear warheads, and the country is believed to possess the ability to deliver them in several methods, including by aircraft, as submarine-launched cruise missiles, and via the Jericho series of intermediate to intercontinental range ballistic missiles. Its first deliverable nuclear weapon is thought to have been completed in late 1966 or early 1967; which would make it the sixth country in the world to have developed them.
Operation Outside the Box, also known as Operation Orchard, was an Israeli airstrike on a suspected nuclear reactor, referred to as the Al Kibar site, in the Deir ez-Zor region of Syria, which occurred just after midnight on 6 September 2007. The Israeli and U.S. governments did not announce the secret raids for seven months. The White House and Central Intelligence Agency (CIA) subsequently confirmed that American intelligence had also indicated the site was a nuclear facility with a military purpose, though Syria denies this. A 2009 International Atomic Energy Agency (IAEA) investigation reported evidence of uranium and graphite and concluded that the site bore features resembling an undeclared nuclear reactor. IAEA was initially unable to confirm or deny the nature of the site because, according to IAEA, Syria failed to provide necessary cooperation with the IAEA investigation. Syria has disputed these claims. Nearly four years later, in April 2011 during the Syrian Civil War, the IAEA officially confirmed that the site was a nuclear reactor. Israel did not acknowledge the attack until 2018.
The Institute for Intelligence and Special Operations, popularly known as Mossad, is the national intelligence agency of the State of Israel. It is one of the main entities in the Israeli Intelligence Community, along with Aman and Shin Bet.
Triple is a spy thriller novel written by British author Ken Follett. It was originally published in 1979. The background of the plot is Operation Plumbat, a 1968 covert operation carried out by Mossad that did not become publicly known about until 1977.
