Kellex
The Kellex Corporation was a wholly owned subsidiary of M. W. Kellogg Company. Kellex was formed in 1942 so that Kellogg's operations relating to the Manhattan Project could be kept separate and secret. "Kell" stood for "Kellogg" and "X" for secret. The new company's goal was to design a facility for the production of enriched uranium through gaseous diffusion. In gaseous diffusion, isotopes of Uranium-235 could be separated from Uranium-238 by turning uranium metal into uranium hexafluoride gas and straining it through a barrier material. History The M. W. Kellogg Company, headquartered in Jersey City, New Jersey, specialized in chemical engineering projects. A year before the Manhattan Project began, the S-1 Section of the Office of Scientific Research and Development asked Kellogg to work with John R. Dunning and other scientists at Columbia University to ascertain the feasibility of gaseous diffusion. The pilot project at Kellogg was led by Percival C. "Dobie" Keith, vice ...

K-25 Project
K-25 was the codename given by the Manhattan Project to the program to produce enriched uranium for atomic bombs using the gaseous diffusion method. Originally the codename for the product, over time it came to refer to the project, the production facility located at the Clinton Engineer Works in Oak Ridge, Tennessee, the main gaseous diffusion building, and ultimately the site. When it was built in 1944, the four-story K-25 gaseous diffusion plant was the world's largest building, comprising over of floor space and a volume of . Construction of the K-25 facility was undertaken by J. A. Jones Construction. At the height of construction, over 25,000 workers were employed on the site. Gaseous diffusion was but one of three enrichment technologies used by the Manhattan Project. Slightly enriched product from the S-50 thermal diffusion plant was fed into the K-25 gaseous diffusion plant. Its product in turn was fed into the Y-12 electromagnetic plant. The enriched uranium was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manhattan Project
The Manhattan Project was a research and development undertaking during World War II that produced the first nuclear weapons. It was led by the United States with the support of the United Kingdom and Canada. From 1942 to 1946, the project was under the direction of Major General Leslie Groves of the United States Army Corps of Engineers, U.S. Army Corps of Engineers. Nuclear physicist Robert Oppenheimer was the director of the Los Alamos Laboratory that designed the actual bombs. The Army component of the project was designated the Manhattan District as its first headquarters were in Manhattan; the placename gradually superseded the official codename, Development of Substitute Materials, for the entire project. Along the way, the project absorbed its earlier British counterpart, Tube Alloys. The Manhattan Project began modestly in 1939, but grew to employ more than 130,000 people and cost nearly US$2 billion (equivalent to about $ billion in ). Over 90 percent of th ...

Clinton Engineer Works
The Clinton Engineer Works (CEW) was the production installation of the Manhattan Project that during World War II produced the enriched uranium used in the 1945 bombing of Hiroshima, as well as the first examples of reactor-produced plutonium. It consisted of production facilities arranged at three major sites, various utilities including a power plant, and the town of Oak Ridge. It was in East Tennessee, about west of Knoxville, and was named after the town of Clinton, to the north. The production facilities were mainly in Roane County, and the northern part of the site was in Anderson County. The Manhattan District Engineer, Kenneth Nichols, moved the Manhattan District headquarters from Manhattan to Oak Ridge in August 1943. During the war, Clinton's advanced research was managed for the government by the University of Chicago. Construction workers were housed in a community known as Happy Valley. Built by the Army Corps of Engineers in 1943, this temporary commun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Woolworth Building
The Woolworth Building is an early skyscraper, early American skyscraper designed by architect Cass Gilbert located at 233 Broadway (Manhattan), Broadway in the Tribeca neighborhood of Manhattan in New York City. It was the tallest building in the world from 1913 to 1930, with a height of . More than a century after its construction, it remains one of the List of tallest buildings in the United States, 100 tallest buildings in the United States. The Woolworth Building is bounded by Broadway and City Hall Park to its east, Park Place to its north, and Barclay Street to its south. It consists of a 30-story base topped by a 30-story tower. Its facade is mostly decorated with architectural terracotta, though the lower portions are limestone, and it features thousands of windows. The ornate lobby contains various sculptures, mosaics, and architectural touches. The structure was designed with several amenities and attractions, including a now-closed observatory on the 57th floor and ...

Vitro Corporation
Vitro Corporation was a major United States defense contractor which became part of BAE Systems Inc. in 1999. History Vitro was incorporated in 1950 as the Vitro Manufacturing Company. Its main product was slide transparencies for overhead projectors. For some time prior to incorporation, the founders had produced tinted lighting gels for the theater and stage industry, and were known for their leadership in the production of gels used to replicate the lighting characteristics of the outdoors on a sunny day. These gels had this quality because of the admixture of salts of uranium, which are bright yellow. This business had positioned Vitro as a ready source of uranium during US military and scientific research efforts into nuclear energy during the Second World War. It seems likely that the confidential relationships developed in this time-frame with US government entities led to later contracting and development business arrangements. In 1950 Vitro acquired the Kellex Corporatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nuclear History Of The United States
Nuclear history of the United States describes the history of nuclear affairs in the United States whether civilian or military. Timeline Manhattan Project The pre- Hiroshima nuclear history of the United States began with the Manhattan Project. This Manhattan Project was the nuclear program for warfare. Even before the first nuclear weapons had been developed, scientists involved with the Manhattan Project were divided over the use of the weapon. The role of the two atomic bombings of the country in Japan's surrender and the U.S.'s ethical justification for them has been the subject of scholarly and popular debate for decades. The question of whether nations should have nuclear weapons, or test them, has been continually and nearly universally controversial.Jerry Brown and Rinaldo Brutoco (1997). ''Profiles in Power: The Anti-nuclear Movement and the Dawn of the Solar Age'', Twayne Publishers, pp. 191–192. Hiroshima and Nagasaki The atomic bombings of Hiroshima and Nagasak ...
