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...
متن کاملA MODEL STUDY OF LASER ISOTOPE SEPARATION BY PHOTOIONIZATION OR PHOTODISSOCIATION PROCESS
In this study, the selective photoexication of isotopic mixtures by laser light is investigated. Atomic and molecular methods are examined and rate equations are derived for both cases. Two and three step photoionization techniques are considered and rate equations are solved for ion yields. The molecular photodissociation process is also studied and the dependence of the dissociation produ...
متن کاملLaser Isotope Enrichment
The idea of laser isotope enrichment grew from the laser’s ability to concentrate its output power in a narrow range of wavelengths. Different isotopes of the same element are very hard or impossible to separate chemically, but the difference in their masses leads to differences in their spectra, which in principle can be used to selectively excite one isotope and isolate it by some photo-induc...
متن کاملLaser isotope separation using two-photon selective excitation; its quantum efficiency and separation factor.
Application of two-photon selective excitation to isotope separation with high power, high resolution tunable lasers is discussed. A simple kinetic model is given to determine quantum efficiency and separation factor in terms of laser powers and relaxation constants. A numerical example is used to demonstrate the feasibility of the scheme. Results indicate that a high quantum yield is obtainabl...
متن کاملLaser Separation of Isotopes
In nature most elements are mixtures of isotopes: they are made up of at oms that all have the same number of protons and electrons but that differ in number of neutrons. Ordinarily the fact that an element is a mixture of sev eral ·kinds of atoms matters little be cause the various isotopes are all but indistinguishable in most of their prop erties. For that very reason. however. when we d...
