[摘要]：This paper discusses a non proliferation assessment of open source data that is related to the large scale production of U-235. Solution methods and engineering models are indicated by referring to standard works in the field of isotope separation. The technique is illustrated with a calculation of the feed flow rate to a 164 first generation machine cascade, such as the Iranian IR-1 cascades that are currently installed in the Iranian Nuclear Fuel Enrichment Plant in Natanz.
