Fordow Fuel Enrichment Plant
Fordow Fuel Enrichment Plant (FFEP) is an Iranian underground uranium enrichment facility located northeast of the Iranian city of Qom, near Fordow village, at a former Islamic Revolutionary Guard Corps base. The site is under the control of the Atomic Energy Organization of Iran (AEOI). It is the second Iranian uranium enrichment facility, the other one being that of Natanz. According to the Institute for Science and International Security, possible coordinates of the facility's location are: . Disclosure Existence of the then-unfinished enrichment plant was disclosed to the International Atomic Energy Agency (IAEA) by Iran on 21 September 2009, but only after the site became known to Western intelligence services. Western officials strongly condemned Iran for not disclosing the site earlier; U.S. President Barack Obama said that Fordow had been under U.S. surveillance. Iran argues that this disclosure was consistent with its legal obligations under its Safeguards Agreement with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uranium Enrichment
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 99.2739–99.2752% natural abundance), uranium-235 (235U, 0.7198–0.7202%), and uranium-234 (234U, 0.0050–0.0059%). 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. The International Atomic Energy Agency attempts to monitor and control enriched uranium supplies and processes in its efforts to ensure nuclear power generation safety and curb nuclear weapons proliferation. There are about 2,000 tonnes of highly enriched uranium in the world, produced mostly for nuclear power, nuclear weapons, naval propulsion, and smaller quantities for research reactors. ...

Meter
The metre (British spelling) or meter (American spelling; see spelling differences) (from the French unit , from the Greek noun , "measure"), symbol m, is the primary unit of length in the International System of Units (SI), though its prefixed forms are also used relatively frequently. The metre was originally defined in 1793 as one ten-millionth of the distance from the equator to the North Pole along a great circle, so the Earth's circumference is approximately km. In 1799, the metre was redefined in terms of a prototype metre bar (the actual bar used was changed in 1889). In 1960, the metre was redefined in terms of a certain number of wavelengths of a certain emission line of krypton-86. The current definition was adopted in 1983 and modified slightly in 2002 to clarify that the metre is a measure of proper length. From 1983 until 2019, the metre was formally defined as the length of the path travelled by light in a vacuum in of a second. After the 2019 redefiniti ...

Isotope Separation Facilities
Isotopes are two or more types of atoms that have the same atomic number (number of protons in their nuclei) and position in the periodic table (and hence belong to the same chemical element), and that differ in nucleon numbers (mass numbers) due to different numbers of neutrons in their nuclei. While all isotopes of a given element have almost the same chemical properties, they have different atomic masses and physical properties. The term isotope is formed from the Greek roots isos ( ἴσος "equal") and topos ( τόπος "place"), meaning "the same place"; thus, the meaning behind the name is that different isotopes of a single element occupy the same position on the periodic table. It was coined by Scottish doctor and writer Margaret Todd in 1913 in a suggestion to the British chemist Frederick Soddy. The number of protons within the atom's nucleus is called its atomic number and is equal to the number of electrons in the neutral (non-ionized) atom. Each atomic num ...

Uranium
Uranium is a chemical element with the 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 is weakly radioactive because all isotopes of uranium are unstable; the half-lives of its naturally occurring isotopes range between 159,200 years and 4.5 billion years. 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 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. In nature, uranium is found as uranium-238 (99. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

S-300 Missile System
The S-300 (NATO reporting name SA-10 Grumble) is a series of long range surface-to-air missile systems developed and operated by the former Soviet Union, now fielded by the militaries of Russia and Ukraine as well as several other former Eastern Bloc countries. It was produced by NPO Almaz, based on the initial S-300P version. The S-300 system was developed to defend against air raids and cruise missiles for the Soviet Air Defence Forces. Subsequent variations were also developed to be able to anti-ballistic missile, intercept ballistic missiles. The S-300 system was first deployed by the Soviet Union in 1979, designed for the air defence of large industrial and administrative facilities, military bases and control of airspace against enemy strike aircraft. During the 2022 Russian invasion of Ukraine, Russian invasion of Ukraine in 2022, military analysts have stated that Russia has modified a number of systems to perform surface-to-surface missile, surface-to-surface strikes. ...

Twelver Usooli and Akhbari Shia Twelver Muslims believe that the study of Islamic literature is a continual process, and is necessary for identifying all of God's laws. Twelver Shia Muslims believe that the process of finding God's laws from the available Islamic literature will facilitate in dealing with any circumstance. They believe that they can interpret the Qur'an and the Twelver Shi'a traditions with the same authority as their predecessors. This process of ijtihad has provided a means to deal with current issues from an Islamic perspective. Generally, clergy in Twelver Shi'a have exerted much more authority in their religious community than the Sunni ulema in theirs.

Shia Muslims
Shīʿa Islam or Shīʿīsm is the second-largest branch of Islam. It holds that the Islamic prophet Muhammad designated ʿAlī ibn Abī Ṭālib as his successor (''khalīfa'') and the Imam (spiritual and political leader) after him, most notably at the event of Ghadir Khumm, but was prevented from succeeding Muhammad as the leader of the Muslims as a result of the choice made by some of Muhammad's other companions (''ṣaḥāba'') at Saqifah. This view primarily contrasts with that of Sunnī Islam, whose adherents believe that Muhammad did not appoint a successor before his death and consider Abū Bakr, who was appointed caliph by a group of senior Muslims at Saqifah, to be the first rightful (''rāshidūn'') caliph after Muhammad. Adherents of Shīʿa Islam are called Shīʿa Muslims, Shīʿītes, or simply Shīʿa or Shia. Shīʿa Islam is based on a ''ḥadīth'' report concerning Muhammad's pronouncement at Ghadir Khumm.Esposito, John.
