| '''Enriched uranium''' is a type of [[uranium]] in which the percent composition of [[uranium-235]] (written <sup>235</sup>U) has been increased through the process of [[isotope separation]].

| Enriched uranium Enriched Uranium is unique because of its dual purpose, it poses a special difficulty for efforts to prevent nuclear proliferation. Its use in nuclear power generation for civilian purposes requires close monitoring to avoid diversion for military uses. Enriched Uranium is a critical component for both civil [[nuclear power]] generation and military [[nuclear weapon]]s. The [[International Atomic Energy Agency]] attempts to monitor and control enriched uranium supplies and processes in its efforts to ensure nuclear power generation safety and curb [[nuclear proliferation|nuclear weapons proliferation]]. This proactive stance has become crucial to the global attempt to uphold a fragile balance between the positive benefits of energy from nuclear reactors and the vital importance of preventing the proliferation of nuclear weapons. | Enriched uranium Enriched Uranium is unique because of its dual purpose, it poses a special difficulty for efforts to prevent nuclear proliferation.
