In uranium enriching cascades, the enrichment obtained on the product can be enhanced by introducing reflux from the product end to the feed stage. The effect of the reflux is analyzed on the basis of the solutions obtained of stagewise discrete flow equations. The degree of enhancement achieved on the enrichment is represented by the ratio of enrichments between the cases with and without reflux. If the enrichment is much smaller than unity, the ratio is constant throughout the cascade, and the value increases monotonously with the reflux rate, reaching its highest value when the reflux is total, to equal the ratio between the enrichment prevailing in the feed flow and that in the waste flow when devoid of reflux.<BR>Comparisons based on a model gas centrifuge cascade are made between three alternative expedients envisaged for enhancing the enrichment-(a) cascade feed flow control, (b) feed stage cut control, and (c) reflux rate control. Of these three expedients, (b) is found to bring about the highest enrichment with the least sacrifice of the separative work.
