Nuclear Fission In simplest terms, nuclear fission is the splitting of an atomic bond. nuclear weapon, device designed to release energy in an explosive manner as a result of nuclear fission, nuclear fusion, or a combination of the two processes. If you are interested in joining our team, please see our current opportunities here. Through two distinct methods, humankind has discovered multiple ways of manipulating the atom to release its internal energy. The directorate leads the Material Plasma Exposure eXperiment (MPEX), a future world-leading capability that will produce the extreme plasma environments to test materials for use in fusion energy devices. Nuclear fusion is a process in which two nuclei join to form a larger nucleus. Nuclear Fusion and Fission delves into nuclear physics and the scientists responsible for the discovery of splitting and fusing an atom. The fusion of four protons to form a helium nucleus, two positrons (and two neutrinos), for example, generates 24.7 MeV of energy.
Fusing two light nuclei can liberate as much energy as the fission of 235 U or 239 Pu. The directorate leverages synergies between fusion and fission across domestic and international programs. Fusion and fission are similar in that they both release large amounts of energy. The graph of binding energy per nucleon suggests another way of obtaining useful energy from nuclear reactions. The Fusion and Fission Energy and Science Directorate (FFESD) addresses compelling challenges in fission and fusion energy systems, enabling Oak Ridge National Laboratory to pursue national priorities in current and advanced nuclear research, development, and deployment.įFESD traces its roots to the X-10 Graphite Reactor, the world’s first continuously operated nuclear reactor, and to early innovations in fusion research and engineering. The directorate’s unique facilities, capabilities, and talented scientists and engineers are currently tackling such challenges as extended operations of the current US nuclear reactor fleet investigating economical and flexible advanced reactor systems and making fusion energy a viable power source.
