There are two basic types of nuclear weapons: those that derive the majority of their energy from nuclear fission reactions alone, and those that use fission reactions to begin,All existing nuclear weapons derive some of their explosive energy from nuclear fission reactions. The amount of energy released by fission bombs can range from the equivalent of just under a ton to upwards of 500,000 tons (500,The most commonly used fissile materials for nuclear weapons applications have been,The other basic type of nuclear weapon produces a large proportion of its energy in nuclear fusion reactions. A week after Nagasaki, Tokyo had still not surrendered. In addition, officials believed Emporer Hirohito might still be needed to help negotiate any surrender.Targets in the south were given priority to boost possible invasion plans but the ancient city of Kyoto was withdrawn because the U.S. Secretary of War, Henry Stimson, who had honeymooned there, said it was an important cultural center and “must not be bombed.”.Kyoto had been favored for the very first attack but the committee opted to blitz Hiroshima, which was an important army depot and embarkation port within an urban environment.In August 6, a B-29 bomber, the Enola Gay, dropped an estimated 12 kilotons of TNT in a uranium bomb termed “Little Boy” on Hiroshima.Just three days another B-29, Bockscar, took off for Kokura carrying a second and more deadly plutonium bomb called “Fat Man,” estimated to be between as powerful as 20 kilotons of TNT. The first bomb was exploded in a test at Alamogordo air base in southern New Mexico on July 16, 1945. A small amount of uranium-235, say 0.45 kg (1 pound), cannot undergo a chain reaction and is thus termed a subcritical mass; this is because, on average, the neutrons released by a fission are likely to leave the assembly without striking another nucleus and causing it to fission. Japanese opposition to nuclear weapons tests in the Pacific Ocean was widespread, and "an estimated 35 million signatures were collected on petitions calling for bans on nuclear weapons".Subsequently, the United States and the Soviet Union halted their programs. A nuclear weapon (also called an atom bomb, nuke, atomic bomb, nuclear warhead, A-bomb, or nuclear bomb) is an explosive device that derives its destructive force from nuclear reactions, either fission (fission bomb) or from a combination of fission and fusion reactions (thermonuclear bomb). ).
