WebApr 11, 2024 · Controlled nuclear fusion generates energy by fusing atoms and could be a safer, cleaner alternative to nuclear fission, the method used in modern nuclear power plants, which splits atoms and produces long-lived radioactive waste. Ideally, nuclear fusion could one day provide plentiful, carbon-free energy. WebWhen nuclear fission is used to generate electricity, it is referred to as nuclear power.In this case, uranium-235 is used as the nuclear fuel and its fission is triggered by the absorption of a slow moving thermal neutron. Other isotopes that can be induced to fission like this are plutonium-239, uranium-233, and thorium-232. For elements lighter than iron …

The graph of binding energy per nucleon suggests another way of obtaining useful energy from nuclear reactions. Fusing two light nuclei can liberate as much energy as the fission of 235 U or 239 Pu. The fusion of four protons to form a helium nucleus, two positrons (and two neutrinos), for example, generates 24.7 MeV of energy.
