The Facts

• Iran offered to limit its enriched uranium stock to up to 60% purity—90% is weapons grade purity—to avoid a resolution at the Nov. 20-22 International Atomic Energy Agency meet condemning its non-cooperation with UN inspectors.

• The nuclear watchdog has said in a confidential report that Tehran has already initiated the process, although hiking uranium enrichment from 60% to 90% is a short process. Iran has also reportedly raised its 60%-purity uranium supply.

• Rafael Grossi, the nuclear monitor's chief, Wednesday called Iran's move a "concrete step," adding it was "taking a different direction." The report also said Iran had 17.6kg more of 60% enriched uranium since the August report.
