Performs detailed calculations for the enrichment of natural and reprocessed uranium by gaseous diffusion: mass balance, concentrations of minor isotopes, the additional enrichment required to compensate for the presence of the neutron-absorbing isotopes U-234 and/or U-236, cost, and optimum tails assay for minimum fuel cost.

Enter a value into any one field of the Material Balance, change any parameters as required, and click the "Calculate" button below.     HELP
"t" means metric tonne.
