super(234)U Content in Enriched Uranium as a Function of the super(234)U Concentration in the Initial Material

The results of calculations of the super(234)U content in enriched uranium are presented. These results substantiate the need to change the ASTM C 996 specification for the maximum super(234)U content in enriched uranium to 11000 kg/g super(235)U and the ASTM C 787 specification for the maximum supe...

Zusammenfassung:The results of calculations of the super(234)U content in enriched uranium are presented. These results substantiate the need to change the ASTM C 996 specification for the maximum super(234)U content in enriched uranium to 11000 kg/g super(235)U and the ASTM C 787 specification for the maximum super(234)U content in the initial material to 60 kg/g U in connection with the possibility of bringing into enrichment production uranium ores with super(234)U content higher than 58 kg/g U. These changes will permit using initial uranium with super(234)U content up to 60 kg/g U when enriching the super(235)U content to 4.95% with 0.36% super(235)U in the waste.
