WebTwo atomic bombs made by the allied powers (USA and UK) from uranium-235 and plutonium-239 were dropped on Hiroshima and Nagasaki respectively early in August 1945. These brought the long Second World War to a sudden end. The immense and previously unimaginable power of the atom had been demonstrated. In the following years several … WebAs uranium-235 is so rare in nature, uranium has to go through a process called enrichment so that enough uranium-235 is present to use as a fuel for nuclear energy. Uranium-238 can be converted to a fissile substance called plutonium-239, in a nuclear reactor, and then used for fission. Another isotope of uranium that is fissile is uranium-233.
