Isotope separation process

Patent ·
OSTI ID:6227391

A process for separating [sup 235]U from a mix of [sup 238]UF[sub 6] and [sup 235]UF[sub 6], to obtain a chemical compound in which the ratio of [sup 235]U to [sup 238]U is higher than in the mix, the process comprising the steps of: combining the mix of [sup 238]UF[sub 6] and [sup 235]UF[sub 6] with at least one type of reactant molecules which is selected from a group consisting of: GeCl[sub 4], GeH[sub 4], SiBr[sub 4], SiCl[sub 4], SiH[sub 4], SiOH[sub 3]F[sub 3], and SiOH[sub 6], to form a mixture thereof; exposing the mixture to electromagnetic energy of at least one predetermined wavelength which is absorbed more strongly by [sup 235]UF[sub 6] than by [sup 238]UF[sub 6], in the presence of at least one type of polar molecule to cause the [sup 235]UF[sub 6] to go from a first physicochemical state to a second physicochemical state where the [sup 235]UF[sub 6], without significantly consuming the polar molecule, combines with the reactant molecules at a higher rate than does [sup 238]UF[sub 6] to form the chemical compound; and separating the chemical compound from the mixture.
