Bright handles enrichment cascades in a very general manner. The Enrichment object supports normal two isotope component mixture enrichment as well as multi-component cascades.
Multi-component enrichment poses a special modeling issue because the problem is underdetermined by an order equal to the number of nuclides in the cascade minus two. (Thus, two-component enrichment is exactly determined.) Therefore, an N-2 dimensional surface of possible solutions exists. The ‘correct’ solution is found by optimizing , the mass at which the overall stage separation factor is unity. This model is largely based off of the work of A. de la Garza, E. von Halle, and H. Wood.
All functionality may be found in the enrichment module:
