One of the only open sources on this facility is an Iranian video published on the Atomic Energy Organization of Iran (AEOI) website, released as part of the 2021 National Nuclear Technology Day. According to the narration associated with the video, this center includes assembly, balancing, and quality control units for the IR-2m, IR-4, and IR-6 centrifuges. According to the video narration, the facility also has the capability to assemble IR-1 centrifuges, if assembly were restarted.

This report provides an in-depth analysis and explanation of the parts of the interim assembly workshop shown in the video and additional information revealed in the video about Iran’s advanced centrifuges, in particular the IR-6 centrifuge. Aside from the video, little information is publicly available about the capabilities of this interim facility, but it appears to have a throughput far smaller than the ICAC, helping explain the delays in installing advanced centrifuges.
