Uranium

Uranium from processing has generally a 235 U nominal content superior to natural uranium (0.72%) so that the use of reprocessed uranium is a gain not only in mass but also as separative work units (SWU), which represent the energy required to increase the concentration of 235 U above that of natural uranium. For reprocessed uranium to be used in the fuel assemblies that power a commercial ...
