International Symposium on Isotope Separation and Chemical Exchange Uranium Enrichment

Laser isotope separation of uranium

A research effort was carried out at the Bhabha Atomic Research Centre (BARC), Mumbai, for developing laser-based techniques for enrichment of natural uranium to reactor-grade (2.5% to 3.0% U), with the potential to be economically scalable to industrial production. Three approaches – two molecular, namely CO2 laser-based approach and UF6-based approach, and one atomic, namely Atomic Vapour Las...

Nitrogen Isotope Separation by Ion Exchange Chromatography

Enriched stable isotopes of many elements have been widely used in many aspects and such isotopes have been primarily used as the tracer for agricultural and biochemical studies and the availability of the isotopically labeled compounds have been now extensively increasing. Chemical exchange separation of isotopes is based on the equilibrium fractionation of isotopes between two phases, ion exc...

The Effect of Temperature on Uranium Isotope Effects Studied by Cation Exchange Displacement Chromatography

The uranium isotope effect in the exchange system uranyl(VI)-malate ligand at 288–343 K has been studied by ion exchange displacement chromatography. At all temperatures 235U is enriched at the front of the uranium band. The single stage separation coefficient, (e =a – 1), increased from (0.9 ± 0.1)× 10 at 288 K to (2.9 ± 0.3)× 10–4 at 343 K. The equilibrium constant of the isotope exchange rea...
