Method for separation of isotopes

Creators

Description

The initial material UCl6 flows through the separation facility in vaporous form, the mixture of isotopes being selectively excited by means of lasers. Separation of the excited molecules is done chemically or physically. The non-excited molecules get to an isotope balancing section, where the chlorine gas is supplied in natural composition with a quantitative ratio of 76 : 24 for 35Cl : 37Cl, and the UCl6 is restored to its original composition. This cycle is repeated for enrichment of 235U or 238U. (DG)

Abstract (German)

Der Ausgangsstoff UCl6 durchstroemt dampffoermig die Trenneinrichtung, worin das Isotopengemisch mittels Laser selektiv angeregt wird. Die Trennung der angeregten Molekuele erfolgt chemisch oder physikalisch. Die nicht angeregten Molekuele gelangen zu einer Isotopenausgleichsstrecke, in das Chlorgas natuerlicher Zusammensetzung im Mengenverhaeltnis 76 : 24 fuer 35Cl zu 37Cl eingeleitet und das UCl6 auf seine urspruengliche Zusammensetzung zurueckgefuehrt wird. Dieser Kreislauf wiederholt sich bis zur Anreicherung des 235U oder 238U. (DG)
