jaderná energie

Jaderná energie, or nuclear energy, refers to the energy produced through nuclear reactions, primarily through the process of nuclear fission or fusion. In nuclear fission, the nucleus of an atom, typically uranium-235 or plutonium-239, is split into smaller nuclei along with the release of a significant amount of energy. This energy can be harnessed to generate electricity in nuclear power plants. In contrast, nuclear fusion involves the merging of light atomic nuclei, such as hydrogen isotopes, to form a heavier nucleus, releasing energy in the process. Nuclear energy is characterized by its high energy density compared to fossil fuels and is utilized for both power generation and scientific applications, such as in medical treatments or research. The management of nuclear waste and safety concerns are significant considerations in the use of nuclear energy.
