Enriched uranium - Wikipedia

Enriched uranium is a type of uranium in which the percent composition of uranium-235 has been increased through the process of isotope separation. Natural uranium is 99.284% 238 U isotope, with 235 U only constituting about 0.711% of its mass. 235 U is the only nuclide existing in nature (in any appreciable amount) that is fissile with thermal neutrons. ...

Uranium - Wikipedia

Uranium is a stone element with symbol U and atomic number 92. It is a silvery-grey metal in the actinide series of the periodic table.A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons.Uranium is weakly radioactive because all isotopes of uranium are unstable, with half-lives varying between 159,200 years and 4.5 billion years.

Uranium Mining Overview - World Nuclear Association

Uranium Mining In the last fifty years uranium has become one of the world's most important energy minerals. It is used almost entirely for making electricity, though a small proportion is used for the important task of producing medical isotopes.

What are the Radioactive Byproducts of Depleted Uranium ...

[ pour la version française] The chart given below lists all of the decay products of uranium-238 in their order of appearance. Uranium-238 is also referred to as ''depleted uranium''. Each radioactive element on the list gives off either alpha radiation or beta radiation -- and sometimes gamma radiation too -- thereby transforming itself into the next element on the list.

NRC: Byproduct Material

Byproduct Material What is meant by byproduct material? The Atomic Energy Act, as revised in 1978 and in 2005 by the Energy Policy Act (EPAct), defines byproduct material in Section 11e.(1) as radioactive material (except special nuclear material) yielded in or made radioactive by exposure to the radiation incident to the process of producing or using special nuclear material.

Reasons for Using Nuclear Power As an Energy Source
