Nuclear explained - U.S. Energy Information Administration (EIA)
In nuclear fission, atoms are split apart, which releases energy . All nuclear power plants use nuclear fission, and most nuclear power plants use uranium atoms. During nuclear fission, a neutron collides with a uranium atom and splits it, releasing a large amount of energy in the form of heat and radiation.

Nuclear weapon - Fission, Fusion, Delivery | Britannica
Nuclear weapon - Fission, Fusion, Delivery: A typical thermonuclear warhead may be constructed according to a two-stage design, featuring a fission or boosted-fission primary (also called the trigger) and a physically separate component called the secondary. Both primary and secondary are contained within an outer metal case. Radiation from the fission explosion of the primary is contained and ...

Discovery of nuclear fission - Wikipedia
Nuclear fission was discovered in December 1938 by chemists Otto Hahn and Fritz Strassmann and physicists Lise Meitner and Otto Robert Frisch. Fission is a nuclear reaction or radioactive decay process in which the nucleus of an atom splits into two or more smaller, lighter nuclei and often other particles. The fission process often produces ...

why is fissile material considered a nuclear material
In nuclear engineering, fissile material is material capable of sustaining a nuclear fission chain reaction.

Meet Lise Meitner, the physicist who discovered how to split an atom
But Meitner had the explanation. So a few weeks later, Meitner wrote her famous fission letter to the editor, ironically explaining the mechanism of "Hahn's discovery.". Even that didn't help her situation. The Nobel Committee awarded the 1944 Nobel Prize in Chemistry "for the discovery of the fission of heavy nuclei" to Hahn alone.
