24 de sept. de 2024 · Manhattan Project, U.S. government research project (1942–45) that produced the first atomic bombs. See Britannica’s interactive timeline of the Manhattan Project. Creation of the U.S. atomic weapons program
The Manhattan Project was a research and development program undertaken during World War II to produce the first nuclear weapons. It was led by the United States in collaboration with the United Kingdom and Canada. From 1942 to 1946, the project was directed by Major General Leslie Groves of the U.S. Army Corps of Engineers.
El Proyecto Manhattan (en inglés: Manhattan Project) fue un proyecto de investigación y desarrollo llevado a cabo durante la Segunda Guerra Mundial que produjo las primeras armas nucleares, liderado por los Estados Unidos con el apoyo del Reino Unido y de Canadá.
Weapons research was based at the new laboratory at Los Alamos, under the leadership of J. Robert Oppenheimer. A bomb design needed to hold fissile material, either uranium or plutonium, and then quickly assemble the material into a critical mass, which would then explode.
The Manhattan Project was responsible for the generation of thousands of new inventions, as represented by patent claims processed in secret by the project, which if filed would have represented some 1% of all patents in force at the end of World War II.
15 de nov. de 2014 · The feed materials program of the Manhattan Project was responsible for procuring uranium-bearing ores and materials and processing them into forms suitable for use as source materials for the Project’s uranium-enrichment factories and plutonium-producing reactors.
By 1942, research efforts focused on the production of fissionable materials—the separation of uranium-235 and the creation of plutonium in a uranium pile. A lesser, if not unimportant, effort was devoted to fast-neutron studies essential to determining the size of critical masses and efficiencies of explosion.
