Iran has injected uranium hexafluoride gas enriched up to 20 percent purity level into a centrifuge at its Natanz nuclear facility, the United Nations nuclear watchdog reports.
"On 25 October 2021, the Agency verified that Iran began feeding (the gas) enriched up to 20% U-235 into a single IR-6 centrifuge in R&D (research and development) line 2 at PFEP (Pilot Fuel Enrichment Plant) in Natanz, the International Atomic Energy Agency (IAEA) said in a report on Monday, according to Reuters.
However, the agency also noted that the country was not keeping the output.
The resulting product and tails streams were being re-combined," the report added, meaning that after separating the enriched product it was mixed with the centrifuge's waste and not kept.
