Natural uranium definition

Natural uranium means uranium with the naturally occurring distribution of uranium isotopes, which is approximately 0.711 weight percent uranium-235, and the remainder by weight essentially uranium-238.

Natural uranium. (0) means uranium containing the mixtures of isotopes occurring in nature.

Natural uranium means uranium (which may be chemically separated) with the naturally occurring distribution of uranium isotopes (about 0.711 weight percent uranium-235, and the remainder by weight essentially uranium-238).

• Natural uranium is only slightly radioactive and the radiation risks from uranium concentrate are relatively low and can be easily managed.Naturally occurring uranium contains 0.7 percent U-235, which is the isotope of uranium that is fissile and can therefore be used as an energy source (the remainder is comprised of U-238).For most reactor types, uranium concentrate cannot itself be used as a nuclear fuel without enrichment and mining is therefore only the first step in the nuclear fuel cycle.

• Natural uranium is currently procured from three sources: Partnership or joint-venture production, long term contracts and spot market contracts.

• Natural uranium was selected as fuel and the contract was awarded to CANDU, a consortium of Atomic Energy of Canada Ltd (AECL) and the Italian construction company, Italimpianti.

• Natural uranium has an isotopic composition of approximately 0.71% U-235, the fissile isotope of uranium.15 Civilian nuclear power fuel is generally enriched to 3%-5% U-235.16 Uranium enrichment in the United States was largely performed using a gaseous diffusion technology until 2013.
