What is enriched uranium?

enriched uranium had the concentration of a particular isotope, uranium 235 or ^{235 , increased above naturally occurring levels. Uranus has at least three isotopes in nature and is particularly useful for nuclear reactors and as a basis for nuclear weapons. Uranus is naturally composed of a very high percentage of 238 and a very small percentage of other isotopes, in 235 is another most common, around 0.7%. The isotopes department can create enriched uranium samples with a higher concentration of isotopes in 235 . For 235}

is important for fuel and nuclear weapons of a nuclear reactor due to its ability to undergo cleavage or distribution. Each atom U

235 , which is divided, releases a huge amount of energy and also a high -energy particle called neutron. Neutron at that time at ^{235 , causing it to distribute and release a chain reaction. When the reaction is slow and controlled, it can be used as it ishim at a nuclear reactor. When the reaction is violent and uncontrolled, the result is a nuclear explosion, a process that was the basis for bombs that the United States dropped to Japan at the end of World War II.}

Depending on the intended use, the enriched uranium produces with various atoms concentrations for 235 . The lowest level is known as a slightly enriched uranium (SEU) and has a concentration of up to approximately 2% for 235 . Another mark is known as Uranus with low enriched (LEUs) and usually has a concentration of approximately 3% or 4% for 235 , which is the highest standard concentration for reactor fuel, although it can be up to 20%.

Highly enriched uranium (Heu), also known, is uranium, is uranium, which has a concentration of approximately 80% for 235 . Uranus enriched with this level is used in the production of weapons that make up nuclear arsenals of many countries, although the level of enrichment up to 20% isSufficient for the production of the simplest nuclear weapons. This class of enriched uranium is highly controlled and regulated by national and international governments and regulatory agencies to promote its safe use and prevent nuclear weapons to prevent world civilizations as a whole consider potentially dangerous or irresponsible.
