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. 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. can diabetics eat snickers
