Technical Note: Making Sense out of the IR-8 Centrifuge | Institute for Science and International Security

Some of the claimed enrichment output is exaggerated as a result of Iran’s use of a non-standard unit for quantifying enrichment output and of theoretical upper bound estimates of centrifuge output. Nonetheless, the IR-8 is more advanced than the IR-2m centrifuge, Iran’s most developed advanced centrifuge. Based on a set of rough estimates, reflecting a lack of data, the IR-8 centrifuge may represent a potential growth of one or two generations in centrifuge development.
