Thus an appropriate place to begin a study of the physics of nuclear power is with the Nuclear power generates more than 20 of the electrical energy in the United States.Basic Definitions. A nuclear reaction can be defined as a collision between two nuclei that produces as change in the nuclear composition and/or the energy state of the interacting species. : of or relating to the atomic nucleus. : used in or produced by a nuclear reaction (such as fission).See the full definition of power. Seen and Heard. What made you want to look up nuclear power? Heres the definition of nuclear fission, with examples and an explanation of how the fission process works and why it happens.Fission is a type of nuclear reaction which may occur spontaneously or as a result of a particle striking an atomic nucleus. "Nuclear reaction" is a term implying an induced change in a nuclide, and thus it does not apply to any type of radioactive decay (which by definition is a spontaneous process). Natural nuclear reactions occur in the interaction between cosmic rays and matter In nuclear physics, nuclear fission is either a nuclear reaction or a radioactive decay process.See next: nuclear binding energy. Definition of 235U Fission Example. Uranium 235 is a fissile isotope and its fission cross-section for thermal neutrons is about 585 barns (for 0.0253 eV neutron).
