http://hyperphysics.phy-astr.gsu.edu/hbase/NucEne/fisfrag.html Webthe fission product yields in all cases. The fission product yields are usually given on a very coarse grid (no more than three points), therefore there is no need to use an elaborate weighting function for averaging. A four-points averaging function is defined according to the following conditions:

WebNeutron poisons are fission products that are of concern in reactors primarily because they become parasitic absorbers of neutrons and result in long-term sources of heat (so-called decay heat). Their buildup in the reactor tends to reduce the multiplication factor. Nuclear fission fragments are the fragments left after a nucleus fissions.

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.

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 two smaller … See more The sum of the atomic mass of the two atoms produced by the fission of one fissile atom is always less than the atomic mass of the original atom. This is because some of the mass is lost as free neutrons, and once kinetic energy … See more Small amounts of fission products are naturally formed as the result of either spontaneous fission of natural uranium, which occurs at a low rate, or as a result of neutrons from See more The purpose of radiological emergency preparedness is to protect people from the effects of radiation exposure after a nuclear accident or … See more Fission products have half-lives of 90 years (samarium-151) or less, except for seven long-lived fission products that have half lives of … See more Each fission of a parent atom produces a different set of fission product atoms.
