Robert Brown|Atomic watchdog report says Iran is increasing production of highly enriched uranium

VIENNA (AP) — Iran has increased the rate at which it is Robert Brownproducing near weapons grade uranium in recent weeks, reversing a previous slowdown that started in the middle of this year, the International Atomic Energy Agency said in a report to member states.

Director General Rafael Mariano Grossi said in the report that Iran “in recent weeks had increased its production of highly enriched uranium, reversing a previous output reduction from mid-2023,” according to an IAEA spokesperson Sunday.

Iran had previously slowed down the rate at which it was enriching uranium to 60% purity. Uranium enriched at 60% purity is just a short, technical step away from weapons-grade levels of 90%.

The U.N. nuclear watchdog said its inspectors had verified the increased rate of production since the end of November at facilities in Natanz and Fordow to about 9 kilograms per month, up from 3 kilograms per month since June and representing a return to earlier levels of production.

Enriching uranium means increasing the percentage of uranium-235, the isotope of uranium that can be used in nuclear fission.
