Isotope separation - Energy Education

Isotope separation is a process of element enrichment by the physical separation of isotopes in a substance. Naturally occurring elements in the earth are often found in ores or in other such amalgamations which contain multiple different isotopes of the certain element. This can raise problems for the applicable uses of certain elements due to the fact that not all of the isotopes are useful ...

The isotopic separation system is used to separate tritium from deuterium and hydrogen. It may be used as the stage following electrolysis in the removal of tritium from heavy water or light water.

Isotopic fractionation | chemistry | Britannica.com

Isotopic fractionation, enrichment of one isotope relative to another in a chemical or physical process. Two isotopes of an element are different in weight but not in gross chemical properties, which are determined by the number of electrons.

Separation of Isotopes - Read Chemistry

Since isotopes have exactly similar chemical properties, their separation by chemical means is out of question. Their difference in those physical properties which depend on the mass of the atom has been utilised to effect their separation.

Separation of Isotopes of Biogenic Elements in Two-phase ...

The chapter elaborates the dependence of mass-exchange characteristics on HNO 3 concentration, type of packing, flow rate, and other parameters of the nitrogen isotope separation process in the Nitrox system. A comparison of nitrogen isotope separation techniques is also presented.

Uranium enrichment - Energy Education

Laser Isotope Separation main article. The use of lasers in a separation process is still being developed. This separation technique requires lower energy input and other economic advantages. In this process, a laser with a very specific frequency interacts with a gas or vapour. Since the frequency has an associated energy, the interaction of the beam with the gas allows for the excitation or ...

Separation of isotopes by laser excitation explained. Separation of isotopes by laser excitation (SILEX) is a process for isotope separation that is used to produce enriched uranium using lasers.

Plasma isotope separation based on ion cyclotron resonance

separation process was termed PEP (Plasma Enrichment Process). Work on rubidium isotope separation at this facility was supported by the DOE [10]. Already in the early 1990s, at a scientific conference in France the problem of obtaining gadolinium enriched by 157Gd isotope via the ICR method was posed [7]. It is known that natural gadolinium is employed as a burnable additive to …
