WebBond cleavage. In chemistry, bond cleavage, or bond fission, is the splitting of chemical bonds. This can be generally referred to as dissociation when a molecule is cleaved into two or more fragments. [1] In general, there are two classifications for bond cleavage: homo lytic and hetero lytic, depending on the nature of the process. 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 ...

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).

WebHomolytic fission. The fission of covalent bond such that , one of the electrons of the shared pair in a covalent bond goes with each of the bonded atoms.Thus in this type of cleavage ,the movement of a single electron takes place instead of an electron pair.Homolytic cleavage produces free radical.

WebDelayed neutrons: Neutrons released by fission products up to several seconds after fission. These enable control of the fission in a nuclear reactor. Depleted uranium: Uranium having less than the natural 0.7% U-235. As a by-product of enrichment in the fuel cycle it generally has 0.25-0.30% U-235, the rest being U-238.
