Fissile Nuclei

• Fissile nuclei refer to atomic nuclei of certain isotopes (variants of an element) that can undergo nuclear fission.
• Nuclear fission is a process in which a heavy nucleus splits into two or nearly two equal parts, releasing a large amount of energy.
• Common examples of fissile nuclei are Uranium-235, Uranium-233 and Plutonium-239.
• Fissile nuclei are critical in the production of nuclear energy. When the fissile nuclei undergo fission, they release energy that can be harnessed to generate electricity in nuclear power plants.
• Nuclear power production involves controlling the fission process in a nuclear reactor. A heavy fissile nucleus absorbs a slow-moving neutron, becomes unstable and then splits apart.
• In addition to generating power, the process of fission in fissile nuclei is also used to create atomic bombs.
• When the nucleus of a fissile atom splits, it not only releases a large amount of energy, but also several neutrons. These neutrons can induce fission in other fissile nuclei, leading to a chain reaction.
• Fissile materials, due to their potential in nuclear weaponry, are closely regulated by international treaties and laws.
• The splitting of fissile nuclei is not a naturally occurring process. It requires the injection of a neutron into the nucleus to initiate the fission process.
• Safe handling and disposal of fissile materials is a major concern due to their radioactive nature. Long-term exposure can lead to severe health hazards including cancer and genetic damage.
