A scheme for producing a diluent for high-enrichment uranium in a double cascade is examined. The marketable product, viz., low-enrichment uranium, is obtained in the product flow of the first cascade; the diluent is obtained in the product flow of the second cascade from the waste flow of the first cascade. To reduce the cost of the separative work performed on the production of all products it is proposed that the feed point for the first cascade be displaced in the direction of the product flow relative to the optimum, calculated from the condition of optimization of the cascade for the production of 235U. A computational experiment shows this scheme to be efficient and the particularities associated with the use of natural uranium and depleted wastes as initial materials.
