Fission physics definition
WebIn nuclear physics, a nuclear chain reaction occurs when one single nuclear reaction causes an average of one or more subsequent nuclear reactions, thus leading to the possibility of a self-propagating series of these reactions. The specific nuclear reaction may be the fission of heavy isotopes (e.g., uranium-235, 235 U). A nuclear chain reaction … WebNuclear Chain Reactions. A chain reaction refers to a process in which neutrons released in fission produce an additional fission in at least one further nucleus. This nucleus in turn produces neutrons, and the process repeats. The process may be controlled (nuclear power) or uncontrolled (nuclear weapons).

WebMay 5, 2024 · A nuclear reactor uses fission to generate heat which's used to power a turbine. A nuclear weapon uses fission to generate massive amounts of heat to forge a devastating shock wave. It's the same reaction. It's the same output. Only the nuclear weapon uses the reaction on a far bigger scale... more fission, more neutrons, more … WebNuclear fission is the splitting of a large atomic nucleus into smaller nuclei. In a nuclear reactor, a neutron is absorbed into a nucleus (typically uranium-235). This causes the …
WebDec 8, 2024 · Fission is the splitting of an atomic nucleus into two or more lighter nuclei accompanied by energy release. The original heavy atom is termed the parent nucleus, and the lighter nuclei are daughter nuclei. … 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.
