Building on major scientific breakthroughs made during the 1930s, the United Kingdom began the world's first nuclear weapons research project, codenamed Tube Alloys, in 1941, during World War II. The United States, in collaboration with the United Kingdom, initiated the Manhattan Project the following year to build a weapon using nuclear fission.
Nuclear nonproliferation, Tennis for Two, the first interactive analog computer game William Alfred Higinbotham [ 1 ] [ 2 ] [ 3 ] (October 22, 1910 – November 10, 1994) was an American physicist . A member of the team that developed the first nuclear bomb , he later became a leader in the nonproliferation movement.
Trinity was the code name of the first detonation of a nuclear weapon, conducted by the United States Army at 5:29 a.m. MWT [a] (11:29:21 GMT) on July 16, 1945, as part of the Manhattan Project. The test was of an implosion-design plutonium bomb, nicknamed " The Gadget ", of the same design as the Fat Man bomb later detonated over Nagasaki ...
1998 – May – India tests five more nuclear weapons as part of Operation Shakti at the Pokhran test site. This was India's second round of nuclear weapons testing. 1998 – May – Pakistan detonates five high-enriched uranium nuclear weapons in the Chagai Hills. A sixth nuclear test, at Kharan, was a plutonium device.
The world's first commercial nuclear power station, Calder Hall at Windscale, England was connected to the national power grid on 27 August 1956. In common with a number of other generation I reactors, the plant had the dual purpose of producing electricity and plutonium-239, the latter for the nascent nuclear weapons program in Britain. [26]
March 2: John R. Dunning's team at Columbia University verifies Niels Bohr's hypothesis that uranium 235 is responsible for fission by slow neutrons. [10]March: University of Birmingham-based scientists Otto Frisch and Rudolf Peierls author the Frisch–Peierls memorandum, calculate that an atomic bomb might need as little as 1 pound (0.45 kg) of enriched uranium to work.
By the time RDS-1 exploded, Kurchatov had decided to work on nuclear power generation, working closely with engineer Nikolay Dollezhal, which would established the Obninsk Nuclear Power Plant, near Moscow.: 37 [31] The site was opened in 1954, which was known for its kind and was the first nuclear power plant in the world.: 37 [31] His ...
Jack W. Aeby (/ ˈ æ b i /; August 16, 1923 – June 19, 2015) was an American environmental physicist most famous for having taken the only well-exposed color photograph of the first detonation of a nuclear weapon on July 16, 1945, at the Trinity nuclear test site in New Mexico. [2] [3]
