Nuclear fission is a reaction in which the nucleus of an atom splits into two or more smaller nuclei. The fission process often produces gamma photons, and releases a very large amount of energy even by the energetic standards of radioactive decay.
The nuclear reaction theorised by Meitner and Frisch with the following nuclear chain reaction theorized by Hahn and Strassmann. [1]Nuclear fission was discovered in December 1938 by chemists Otto Hahn and Fritz Strassmann and physicists Lise Meitner and Otto Robert Frisch.
A nuclear explosion is an explosion that occurs as a result of the rapid release of energy from a high-speed nuclear reaction.The driving reaction may be nuclear fission or nuclear fusion or a multi-stage cascading combination of the two, though to date all fusion-based weapons have used a fission device to initiate fusion, and a pure fusion weapon remains a hypothetical device.
Nuclear fission products are the atomic fragments left after a large atomic nucleus undergoes nuclear fission. Typically, a large nucleus like that of uranium fissions by splitting into two smaller nuclei, along with a few neutrons , the release of heat energy ( kinetic energy of the nuclei), and gamma rays .
The resulting explosion is wildly hot—so hot that the immediate area actually briefly resembles the conditions extant in the universe one single second after the Big Bang, resulting in a soup of ...
Between 1939 and 1940, Joliot-Curie's team applied for a patent family covering different use cases of atomic energy, one (case III, in patent FR 971,324 - Perfectionnements aux charges explosives, meaning Improvements in Explosive Charges) being the first official document explicitly mentioning a nuclear explosion as a purpose, including for ...
Georgia Power announced Monday that the first of two nuclear reactors under construction at Plant Vogtle, in Burke County, has achieved “initial criticality,” meaning engineers have begun ...
The effects of a nuclear explosion on its immediate vicinity are typically much more destructive and multifaceted than those caused by conventional explosives. In most cases, the energy released from a nuclear weapon detonated within the lower atmosphere can be approximately divided into four basic categories: [ 1 ]
