Webb15 aug. 2024 · Nuclear fission involves splitting atoms into smaller parts, and releases a lot of energy. After millennia of exploiting sources of chemical energy, such as wood, the discovery of nuclear fission in the 1930s gave humanity access to something far more potent: energy released by the splitting – ‘fission’ – of atomic nuclei. WebbIn simplest terms, nuclear fission is the splitting of an atomic bond. Given that it requires great energy separate two nucleons, it may come as a surprise to learn that splitting a nucleus can release vast potential energy. And although it is true that huge amounts of energy can be released, considerable effort is needed to do so in practice.
