Urenco
The Urenco Group is a British-German-Dutch nuclear fuel consortium operating several uranium enrichment plants in Germany, the Netherlands, United States, and United Kingdom. It supplies nuclear power stations in about 15 countries, and states that it had a 29% share of the global market for enrichment services in 2011. Urenco uses Zippe-type centrifuge, centrifuge enrichment technology. Urenco, headquartered in Stoke Poges, England, is owned one third by the UK government, one third by the Dutch government, and the final third equally by two major German utilities, E.ON and RWE. Group structure Ownership Urenco is owned in three equal parts by Ultra-Centrifuge Nederland NV (owned by the Politics of the Netherlands, Government of the Netherlands), Uranit GmbH (owned equally by German energy companies E.ON and RWE) and Enrichment Holdings Ltd (owned by the Government of the United Kingdom and managed by UK Government Investments). The company was set up in 1971, pursuant t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zippe-type Centrifuge
The Zippe-type centrifuge is a gas centrifuge designed to enrich the rare fissile isotope uranium-235 (235U) from the mixture of isotopes found in naturally occurring uranium compounds. The Isotope separation, isotopic separation is based on the slight difference in mass of the isotopes. The Zippe design was originally developed in the Soviet Union by a team led by 60 Austrian and German scientists and engineers captured after World War II, working in detention. In the West (and now generally) the type is known by the name of the man who recreated the technology after his return to the West in 1956, based on his recollection of his work in (and contributions to) the Soviet program, Gernot Zippe. To the extent that it might be referred to in Soviet/Russian usage by any one person's name, it was known (at least at a somewhat earlier stage of development) as a Kamenev centrifuge (after Evgeni Kamenev).Oleg Bukharin, OlegRussia’s Gaseous Centrifuge Technology and Uranium Enrichment Co ...

Stoke Poges
Stoke Poges () is a village and civil parish in south-east Buckinghamshire, England. It is centred north-north-east of Slough, its post town, and is southeast of Farnham Common. In 2021, it had a population of 5,067. Geography Hamlets within Stoke Poges parish include: * Hollybush Hill * Stoke Green * West End * Wexham Street Etymology In the name Stoke Poges, ''stoke'' means " stockaded (place)" that is staked with more than just boundary-marking stakes. In the Domesday Book of 1086, the village was recorded as ''Stoche''. William Fitz-Ansculf, who held the manor in 1086 (in the grounds of which the Norman parish church was built), later became known as William Stoches or William of Stoke. Two hundred years later Amicia of Stoke, heiress to the manor, married Robert Pogeys, Knight of the Shire, and the village eventually became known as Stoke Poges. Robert Poges was the son of Savoyard Imbert Pugeys, valet to King Henry III and later steward of the royal household. Pog ...

Abdul Qadeer Khan
Abdul Qadeer Khan (1 April 1936 – 10 October 2021) was a Pakistani Nuclear physics, nuclear physicist and metallurgist, metallurgical engineer. He is colloquially known as the "father of Pakistan and weapons of mass destruction, Pakistan's atomic weapons program". A Muhajir (Pakistan), Muhajir emigrant from India who migrated to Pakistan in 1952, Khan was educated in the metallurgical engineering departments of Western European technical universities where he pioneered studies in phase transitions of alloy, metallic alloys, uranium metallurgy, and isotope separation based on gas centrifuges. After learning of India's "Smiling Buddha" nuclear test in 1974, Khan joined his nation's clandestine efforts to develop atomic weapons when he founded the Khan Research Laboratories (KRL) in 1976 and was both its chief scientist and director for many years. In January 2004, Khan was subjected to a debriefing by the Pervez Musharraf#Chief Executive of Pakistan, Musharraf administration ...

National Enrichment Facility
The National Enrichment Facility (NEF) is a nuclear facility for the enrichment of uranium associated with the Los Alamos National Laboratory. The plant uses a gas centrifuge technology known as Zippe-type centrifuges. It is located east of Eunice, New Mexico. The NEF is operated by Louisiana Energy Services (LES), which is in turn owned by the Urenco Group. As of 2011, LES operates as URENCO USA. NEF employs a new type of license, the 10 CFR Part 2. It is a combination license granted by the Nuclear Regulatory Commission (NRC) allowing the plant to proceed directly from construction to operation. First of its kind, this means NEF will be closely watched by many parties in the nuclear community. The original proposed budget was US$1.5 billion, but this increased to US$3 billion for an enlarged facility capable of 5.9 million SWU at full capacity. Since the Dedication Ceremony in October 2008, the company has grown to 236 employees with an annual payroll of US$23 million. At ful ...

Highly 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 1940s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Depleted Uranium Hexafluoride
Depleted uranium hexafluoride (DUHF; also referred to as depleted uranium tails, depleted uranium tailings or DUF6) is a byproduct of the processing of uranium hexafluoride into enriched uranium. It is one of the chemical forms of depleted uranium (up to 73-75%), along with depleted triuranium octoxide (up to 25%) and depleted uranium metal (up to 2%). DUHF is 1.7 times less radioactive than uranium hexafluoride and natural uranium. History The concept of depleted and enriched uranium emerged nearly 150 years after the discovery of uranium by Martin Klaproth in 1789. In 1938, two German physicists Otto Hahn and Fritz Strassmann had made the discovery of the fission of the atomic nucleus of the 235 U isotope, which was theoretically substantiated by Lise Meitner, Otto Robert Frisch and in parallel with them Gottfried von Droste and Siegfried Flügge. This discovery marked the beginning of the peaceful and military use of the nuclear energy of uranium. A year later, Yulii ...

Project-706
Project-706, also known as Project-786 was the codename of a research and development program to develop Pakistan's first nuclear weapons. The program was initiated by Prime Minister Zulfiqar Ali Bhutto in 1974 in response to the Indian nuclear tests conducted in May 1974. During the course of this program, Pakistani nuclear scientists and engineers developed the requisite nuclear infrastructure and gained expertise in the extraction, refining, processing and handling of fissile material with the ultimate goal of designing a nuclear device. These objectives were achieved by the early 1980s with the first successful cold test of a Pakistani nuclear device in 1983. The two institutions responsible for the execution of the program were the Pakistan Atomic Energy Commission and the Kahuta Research Laboratories, led by Munir Ahmed Khan and Abdul Qadeer Khan respectively. In 1976 an organization called Special Development Works (SDW) was created within the Pakistan Army, directly unde ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
