Webcritical mass, in nuclear physics, the minimum amount of a given fissile material necessary to achieve a self-sustaining fission chain reaction under stated conditions. Its size depends on several factors, including the kind of fissile material used, its concentration and purity, and the composition and geometry of the surrounding reaction system. WebNuclear fission is a reaction wherein a heavy nucleus is bombarded by neutrons and thus becomes unstable, which causes it to decompose into two nuclei with equivalent size and magnitude, with a great detachment of energy and the emission of two or three neutrons.

WebJan 6, 2010 · In nuclear fission, energy is derived when a heavy element such as fissions or “splits” apart. The fission reaction can be written as. (1) where F 1 and F 2 are fission fragments. Typically, an impinging neutron initiates the fission reaction, and the reaction yields an average of 2.5 neutrons per fission. The fission fragments and the ... WebJul 9, 2024 · Fission and fusion are both natural atomic processes that release incredible amounts of energy, but in many ways, they are opposites.
