Carson Mark
Jordan Carson Mark (July 6, 1913 – March 2, 1997) was a Canadian-American mathematician best known for his work on developing nuclear weapons for the United States at the Los Alamos National Laboratory. Mark joined the Manhattan Project in 1945, and continued to work at Los Alamos under the leadership of Norris Bradbury after World War II ended. He became the leader of the Theoretical Division at the laboratory in 1947, a position he held until 1973. He oversaw the development of new weapons, including the hydrogen bomb in the 1950s. On the hydrogen bomb project he was able to bring together experts like Edward Teller, Stanislaw Ulam and Marshall Holloway despite their personal differences. In July and August 1958, and again the following year, Mark was a scientific adviser to the United States delegation at the Conference of Experts on Detection of Nuclear Explosions. He served on the United States Air Force's Scientific Advisory Board, and its Foreign Weapons Evaluation Group ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lindsay, Ontario
Lindsay is a community of 22,367 people ( 2021 census) on the Scugog River in the Kawartha Lakes region of south-eastern Ontario, Canada. It is approximately west of Peterborough. It is located in the City of Kawartha Lakes, and is the hub for business and commerce in the region. History The Township of Ops was surveyed in 1825 by Colonel Duncan McDonell, and Lots 20 and 21 in the 5th Concession were reserved for a town site. The same year settlers began to come to the region, and by 1827, the Purdys, an American family, built a dam on the Scugog River at the site of present-day Lindsay. The following year they built a sawmill, and in 1830, a grist mill was constructed. A small village grew up around the mills, and it was known as Purdy's Mills. In 1834, surveyor John Huston plotted the designated town site into streets and lots. Local lore claims that during the survey, one of Huston's assistants, Mr. Lindsay, was accidentally shot in the leg and died of an infection. He ...

Edward Teller
Edward Teller (; January 15, 1908 – September 9, 2003) was a Hungarian and American Theoretical physics, theoretical physicist and chemical engineer who is known colloquially as "the father of the hydrogen bomb" and one of the creators of the History of the Teller–Ulam design, Teller–Ulam design based on Stanisław Ulam's design. He had a volatile personality, and was "driven by his megaton ambitions, had a Messiah complex, messianic complex, and displayed autocratic behavior." A thermonuclear design he devised was an Alarm Clock model bomb with a yield of 1000 MT (1 GT of TNT) and he proposed delivering it by boat or submarine. It would be capable of incinerating a continent. Born in Austria-Hungary in 1908, Teller emigrated to the US in the 1930s, one of the many so-called The Martians (scientists), "Martians", a group of Hungarian scientist émigrés. He made numerous contributions to Nuclear physics, nuclear and molecular physics, spectroscopy, and Surface science, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Operation Sandstone
Operation Sandstone was a series of nuclear weapon tests in 1948. It was the third series of American tests, following Trinity in 1945 and Crossroads in 1946, and preceding Ranger. Like the Crossroads tests, the Sandstone tests were carried out at the Pacific Proving Grounds, although at Enewetak Atoll rather than Bikini Atoll. They differed from Crossroads in that they were conducted by the Atomic Energy Commission, with the armed forces having only a supporting role. The purpose of the Sandstone tests was also different: they were primarily tests of new bomb designs, especially the more efficient levitated pits, rather than of the effects of nuclear weapons. Three tests were carried out in April and May 1948 by Joint Task Force 7, with a work force of 10,366 personnel, of whom 9,890 were military. The successful testing of the new cores in the Operation Sandstone tests rendered every component of the old weapons obsolete. Even before the third test had been carried out, p ...

Los Alamos Laboratory
The Los Alamos Laboratory, also known as Project Y, was a secret scientific laboratory established by the Manhattan Project and overseen by the University of California during World War II. It was operated in partnership with the United States Army. Its mission was to design and build the History of nuclear weapons, first atomic bombs. J. Robert Oppenheimer was its first director, serving from 1943 to December 1945, when he was succeeded by Norris Bradbury. In order to enable scientists to freely discuss their work while preserving security, the laboratory was located on the isolated Pajarito Plateau in Northern New Mexico. The wartime laboratory occupied buildings that had once been part of the Los Alamos Ranch School. The development effort initially focused on a gun-type fission weapon using plutonium called Thin Man (nuclear bomb), Thin Man. In April 1944, the Los Alamos Laboratory determined that the rate of spontaneous fission in plutonium bred in a nuclear reactor was t ...

Montreal Laboratory
The Montreal Laboratory was a program established by the National Research Council of Canada during World War II to undertake nuclear research in collaboration with the United Kingdom, and to absorb some of the scientists and work of the Tube Alloys nuclear project in Britain. It became part of the Manhattan Project, and designed and built some of the world's first nuclear reactors. After the Fall of France, some French scientists escaped to Britain with their stock of heavy water. They were temporarily installed in the Cavendish Laboratory at the University of Cambridge, where they worked on reactor design. The MAUD Committee was uncertain whether this was relevant to the main task of Tube Alloys, that of building an atomic bomb, although there remained a possibility that a reactor could be used to breed plutonium, which might be used in one. It therefore recommended that they be relocated to the United States, and co-located with the Manhattan Project's reactor effort. Due t ...

Nuclear Control Institute
The Nuclear Control Institute is a research and advocacy center for preventing nuclear proliferation and nuclear terrorism. The non-profit organization was founded by Paul Leventhal in 1981. It went under a reorganization in 2003 to make it a web-based program. The institute is supported by the donations of philanthropic foundations and individuals. The Nuclear Control Institute is particularly focused on the elimination of plutonium and highly enriched uranium, which can be used to create nuclear weapons, from nuclear power plants and research reactors, and preventing plutonium and highly enriched uranium from dismantled nuclear weapons from being disposed of in commercial reactors. This means that they are strongly opposed to the use of mixed oxide fuel. Tom Clements is the executive director.

Nuclear Regulatory Commission
The United States Nuclear Regulatory Commission (NRC) is an independent agency of the United States government tasked with protecting public health and safety related to nuclear energy. Established by the Energy Reorganization Act of 1974, the NRC began operations on January 19, 1975, as one of two successor agencies to the United States Atomic Energy Commission. Its functions include overseeing reactor safety and security, administering reactor licensing and renewal, licensing and oversight for fuel cycle facilities, licensing radioactive materials, radionuclide safety, and managing the storage, security, recycling, and disposal of spent fuel. History Prior to 1975 the Atomic Energy Commission was in charge of matters regarding radionuclides. The AEC was dissolved, because it was perceived as unduly favoring the industry it was charged with regulating.John Byrne and Steven M. Hoffman (1996).
