Nuclear energy is a form of energy that is generated by the splitting or fusing of atoms. This type of energy has been used for many purposes, including electricity generation, medical applications, and military applications. Nuclear energy can be generated in several different ways, including through nuclear fission and nuclear fusion. Nuclear fission involves splitting an atom's nucleus into two or more smaller nuclei, while nuclear fusion involves combining two or more nuclei to form a larger nucleus. Both processes release large amounts of energy in the form of heat and radiation.

Nuclear power is the use of nuclear reactions that release energy to generate heat, which most frequently is then used in steam turbines to produce electricity in a nuclear power plant. As of 2020, 14 countries worldwide are operating nuclear power plants, with a total of about 450 reactors. Nuclear power is controversial due to its environmental and safety concerns. Proponents of nuclear power argue that it is a reliable and relatively clean source of energy, while opponents contend that it poses numerous threats to people and the environment.

elements are matrix elements of nuclear operators between nuclear states. These matrix elements are important for calculations of nuclear properties, such as nuclear decay rates and transition probabilities. They are also used in the study of nuclear structure and in the description of nuclear reactions. Nuclear matrix elements can be calculated using a variety of theoretical methods, including shell model, Hartree-Fock, and density functional theory.

Nuclear fusion is the process by which two or more atomic nuclei join together to form a single, heavier nucleus. It is the process that powers the sun and other stars. It occurs when two nuclei, typically of hydrogen, collide at very high speeds and fuse together to form a heavier nucleus such as helium. This fusion releases a tremendous amount of energy in the form of heat and light.
