Laser Isotope Separation of Zirconium for Nuclear Transmutation Process

A 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...

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...

Design and Fabrication of Photochemical Reactor for Scaling up Operation of Laser Isotope Separation Process

atural carbon consists of two stable isotopes, viz. C-13 (1.11%) and C-12 (98.89%). Carbon-13 is an important isotope as a tracer in chemistry, life sciences, medicine and biochemical synthesis. Although the current world production of C-13 at 90% concentration is about 10 kg per annum, an optimistic projection of hundred fold increase in the market demand is anticipated in view of rapid develo...

Design of Optimal Process Flowsheet for Fractional Crystallization Separation Process

A procedure is presented that synthesizes fractional crystallization separation processes to obtain pure solids from multi-component solutions. The method includes a procedure to generate a network flow model to identify alternative process designs for fractional crystallization. The main advantage of this systematic procedure with respect to other reported procedures is using non-equilibri...
