Nuclear Fuel
Nuclear fuel refers to any substance, typically fissile material, which is used by nuclear power stations or other atomic nucleus, nuclear devices to generate energy. Oxide fuel For fission reactors, the fuel (typically based on uranium) is usually based on the metal oxide; the oxides are used rather than the metals themselves because the oxide melting point is much higher than that of the metal and because it cannot burn, being already in the oxidized state. Uranium dioxide Uranium dioxide is a black semiconductor, semiconducting solid. It can be made by heating uranyl nitrate to form . : This is then converted by heating with hydrogen to form UO2. It can be made from Enriched uranium, enriched uranium hexafluoride by reacting with ammonia to form a solid called ammonium diuranate, . This is then heated (Calcination, calcined) to form and U3O8 which is then converted by heating with hydrogen or ammonia to form UO2. The UO2 is mixed with an organic binder and pressed in ...

Nuclear Program Of Iran
The nuclear program of Iran is one of the most scrutinized nuclear programs in the world. The military capabilities of the program are possible through its mass enrichment activities in facilities such as Natanz and Arak. In June 2025, the International Atomic Energy Agency (IAEA) found Iran non-compliant with its nuclear obligations for the first time in 20 years. Iran retaliated by launching a new enrichment site and installing advanced centrifuges. Iran's nuclear program began in the 1950s under the Pahlavi dynasty with US support. It expanded in the 1970s with plans for power reactors, paused after the 1979 Iranian Revolution, and resumed secretly during the 1980s Iran–Iraq War. In the 1990s, Iran pursued a full nuclear fuel cycle and acquired centrifuge technology through illicit networks, including ties with Pakistan and North Korea. Undeclared enrichment sites at Natanz and Arak were exposed in 2002, and Fordow, an underground fuel enrichment site, was reveale ...

Shahram Amiri
Shahram Amiri ( ''Šahrâm Amiri''; 8 November 1978 – 3 August 2016) was an Iranian nuclear scientist who disappeared from Iran during 2009–2010 under disputed circumstances, and was executed by the Government of Islamic Republic of Iran, Iranian government in August 2016. In the spring of 2009, he disappeared while apparently on a pilgrimage to Mecca, Saudi Arabia. On 27 September 2009, Tehran Bureau noted conflicting information regarding the date of his disappearance: the ''Tehran Times'' claimed that Amiri disappeared on 31 May, but Press TV claimed he disappeared in June. In the same announcement by Tehran Bureau, it was claimed that Amiri conducted research on particle physics at the Malek-Ashtar University of Technology in Tehran and that this institution was controlled by the Islamic Revolutionary Guard Corp. About a year after his disappearance, two videos appeared, each purporting to be declarations by Amiri, but with contradictory stories. One showed him (or the pe ...

Hossein Marashi
Hossein Marashi (; born 17 November 1958 in Rafsanjan) is an Iranian politician. He served as the Iranian Vice President for Cultural Heritage and Tourism from 2003 to 2005. Prior to that, Marashi represented Kerman in the Iranian parliament. He strongly backed opposition candidate Mousavi in the 2009 Iranian election. Marashi is also reportedly a close ally of Akbar Hashemi Rafsanjani, another former president. He has been secretary general of the Executives of Construction Party. He has been named the head of vice-president Eshaq Jahangiri's campaign. He was the head of the province of Kerman for nearly nine years. He founded a Kerman-based charity by the name of Mol-Al-Movahedin Charity (or Non-Profit) Institute, which owns Mahan Air, an Iranian private airline. In 2011, the charity was involved in a scandal when it was accused of buying airplanes on behalf of Mahan Air. The airline had been facing sanctions by the United States Department of the Treasury The Dep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Enriched Uranium
Enriched uranium is a type of uranium in which the percent composition of uranium-235 (written 235U) has been increased through the process of isotope separation. Naturally occurring uranium is composed of three major isotopes: uranium-238 (238U with 99.2732–99.2752% natural abundance), uranium-235 (235U, 0.7198–0.7210%), and uranium-234 (234U, 0.0049–0.0059%). 235U is the only nuclide existing in nature (in any appreciable amount) that is fissile with thermal neutrons. Enriched uranium is a critical component for both civil nuclear power generation and military nuclear weapons. Low-enriched uranium (20% 235U, typically >85%) is used for the cores of many nuclear weapons, as well as compact reactors for naval propulsion and research, as well as breeder reactors. There are about 2,000 tonnes of highly enriched uranium in the world. Enrichment methods were first developed on a large scale by the Manhattan Project. Its gaseous diffusion method was used in the 194 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of States With Nuclear Weapons
Nine sovereign states are generally understood to possess nuclear weapons, though only eight formally acknowledge possessing them. Five are considered to be nuclear-weapon states (NWS) under the terms of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT). In order of acquisition of nuclear weapons, these are the United States, Russia (the successor of the former Soviet Union), the United Kingdom, France, and China. Other states that have declared nuclear weapons possession are India, Pakistan, and North Korea. Since the NPT entered into force in 1970, these three states were not parties to the Treaty and have conducted overt nuclear tests. North Korea had been a party to the NPT but withdrew in 2003. Israel is also generally understood to have nuclear weapons, but does not acknowledge it, maintaining a policy of deliberate ambiguity. Israel is estimated to possess somewhere between 90 and 300 nuclear warheads. One possible motivation for ''nuclear ambiguity'' ...

Uranium
Uranium is a chemical element; it has chemical symbol, 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 radioactive decay, radioactively decays, usually by emitting an alpha particle. The half-life of this decay varies between 159,200 and 4.5 billion years for different isotopes of uranium, isotopes, making them useful for dating the age of the Earth. The most common isotopes in natural uranium are uranium-238 (which has 146 neutrons and accounts for over 99% of uranium on Earth) and uranium-235 (which has 143 neutrons). Uranium has the highest atomic weight of the primordial nuclide, 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 notation#Parts-per expressions, parts per million in soil, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
