![]() If you are interested in joining our team, please see our current opportunities here. Fission, which powers todays nuclear reactors, is the opposite of fusion. 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. ![]() hydrogen nucleus) and through a series of steps, these protons fuse together and. Inside the Sun, this process begins with protons (which is simply a lone. ![]() type of fusion that occurs inside of the Sun is known as proton-proton fusion. Nuclear Fission In simplest terms, nuclear fission is the splitting of an atomic bond. nuclear fusion process that is occurring inside the core of the Sun. Tritium implanted into plasma-facing components can become trapped or permeate outside primary systems. Abundant energy: Fusing atoms together in a controlled way releases nearly four million times more energy. The challenges due to radioactive tritium are numerous. The following advantages make fusion worth pursuing. Its isotopes, deuterium and tritium, comprise the fuel in fusion reactions. ![]() The directorate leverages synergies between fusion and fission across domestic and international programs. Through two distinct methods, humankind has discovered multiple ways of manipulating the atom to release its internal energy. Hydrogen plays a central role in fusion and fission systems. Today, we know that the sun, along with all other stars, is powered by a reaction called nuclear fusion. The fusion process is a reverse of what happens in existing nuclear power plants nuclear fission where energy is released when large atoms are broken down into smaller ones. 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. During the early 1960s, pioneering results of nuclear fusion research were presented at the first FEC in Salzburg, Austria, in 1961 and at the second FEC in Culham, United. ![]()
