B ReactorThe B Reactor at the Hanford Site, near Richland, Washington, was the first large-scale nuclear reactor ever built. The project was a key part of the Manhattan Project, the United States nuclear weapons development program during World War II. Its purpose was to convert natural (not isotopically enriched) uranium metal into plutonium-239 by neutron activation, as plutonium is simpler to chemically separate from spent fuel assemblies, for use in nuclear weapons, than it is to isotopically enrich uranium into weapon-grade material.
Pumpkin bombPumpkin bombs were conventional aerial bombs developed by the Manhattan Project and used by the United States Army Air Forces against Japan during World War II. It was a close replication of the Fat Man plutonium bomb with the same ballistic and handling characteristics, but it used non-nuclear conventional high explosives. It was mainly used for testing and training purposes, which included combat missions flown with pumpkin bombs by the 509th Composite Group.
National Museum of the United States Air ForceThe National Museum of the United States Air Force (formerly the United States Air Force Museum) is the official museum of the United States Air Force located at Wright-Patterson Air Force Base, northeast of Dayton, Ohio. The NMUSAF is the oldest and largest military aviation museum in the world, with more than 360 aircraft and missiles on display. The museum draws about a million visitors each year, making it one of the most frequently visited tourist attractions in Ohio.
Tube AlloysTube Alloys was the research and development programme authorised by the United Kingdom, with participation from Canada, to develop nuclear weapons during the Second World War. Starting before the Manhattan Project in the United States, the British efforts were kept classified, and as such had to be referred to by code even within the highest circles of government. The possibility of nuclear weapons was acknowledged early in the war.
HibakushaHibakusha (çibaꜜkɯ̥ɕa or çibakɯ̥ꜜɕa; 被爆者 or 被曝者; "survivor of the bomb" or "person affected by exposure [to radioactivity]") is a word of Japanese origin generally designating the people affected by the atomic bombings of Hiroshima and Nagasaki at the end of World War II. The word hibakusha is Japanese, originally written in kanji. While the term Hibakusha 被爆者 (hi 被 "affected" + baku 爆 "bomb" + sha 者 "person") has been used before in Japanese to designate any victim of bombs, its worldwide democratization led to a definition concerning the survivors of the atomic bombs dropped in Japan by the United States Army Air Forces on the 6 and 9 August 1945.
