  1. Nuclear fission - Wikipedia

    Nuclear fission produces energy for nuclear power and drives the explosion of nuclear weapons. Both uses are possible because certain substances called nuclear fuels undergo fission when struck by …

  2. Fission Uranium: Home

    In January, 2015, Fission Uranium announced a major resource estimate in the indicated and inferred categories which, at that time, was the largest undeveloped resource in the Athabasca Basin region.

  3. The Fission Process – MIT Nuclear Reactor Laboratory

    As fewer and fewer neutrons are absorbed, more and more neutrons are available to cause the splitting of uranium nuclei, until finally enough neutrons are available to sustain a chain reaction.

  4. Physics of Uranium and Nuclear Energy

    Mar 30, 2026 · Neutrons in motion are the starting point for everything that happens in a nuclear reactor. When a neutron passes near to a heavy nucleus, for example uranium-235, the neutron may be …

  5. Nuclear fission | Examples & Process | Britannica

    Mar 20, 2026 · Nuclear fission, subdivision of a heavy atomic nucleus, such as that of uranium or plutonium, into two fragments of roughly equal mass. The process is accompanied by the release of …

  6. DOE Explains...Nuclear Fission - Department of Energy

    Scientists use the term fission cross-section to describe the likelihood that fission will occur. Fission cross-section depends on the energy of the incoming particle and the material of the nuclei that are …

  7. Understand Nuclear Fission | Understand Energy Learning Hub

    Jul 30, 2025 · Uranium occurs naturally in two forms: U-235 and U-238. U-235 is fissile, meaning that it's capable of capturing a slow neutron, splitting apart, and releasing lots of energy and more neutrons, …

  8. Fission Uranium Corp. - Wikipedia

    Fission Uranium Corp. is a mineral exploration company engaged in the exploration and development of uranium assets. Its sole project is the Patterson Lake South (PLS) Project located in Canada's …

  9. What is Uranium? How Does it Work? - World Nuclear Association

    Jan 20, 2026 · In a nuclear reactor the uranium fuel is assembled in such a way that a controlled fission chain reaction can be achieved. The heat created by splitting the U-235 atoms is then used to make …

  10. Fission - Understand Energy Learning Hub

    Most nuclear power plants today are fueled by enriched uranium 235 to produce non-renewable, carbon-free, 24/7 electricity. The byproducts of nuclear fission are highly radioactive and must be secured …
