Thin Man (nuclear bomb) Thin Man (nuclear bomb) "Thin Man" was the code name for a proposed plutonium gun-type nuclear bomb using plutonium-239 which the United States was developing during the Manhattan Project. They aborted its development when they discovered that the spontaneous fission rate of their nuclear reactor-bred plutonium was too high for use in a gun-type design, due to the high concentration of the isotope plutonium-240. In 1942, prior to the Army taking over wartime atomic research, Robert Oppenheimer held conferences in Chicago in June and Berkeley, California, in July at which various engineers and physicists discussed nuclear bomb design issues.

Soviet atomic bomb project cash from other countries in exchange for taking their radioactive byproducts of nuclear industry. Although the bill stipulates that the revenue go towards decontaminating other test sites such as Semipalatinsk and the Kona Peninsula, experts doubt whether this will actually happen given the current political and economic climate in Russia. Soviet atomic bomb project The Soviet atomic bomb project (Russian: Советский проект атомной бомбы, "Sovetskiy proyekt atomnoy bomby") was the classified research and development program that was authorized by Joseph Stalin in the Soviet Union to develop nuclear weapons during World War II. Although the Soviet scientific community discussed the
