VIENNA—Iran is expanding its enrichment of uranium beyond the highly enriched threshold of 20 percent purity at a Natanz plant where it is already enriching to 60 percent, but the new activity does not involve keeping the product, the U.N nuclear watchdog said on Monday.
The move is likely to help Iran refine its knowledge of the enrichment process—something Western powers generally condemn because it is irreversible—but since this time the product is not being collected it will not immediately accelerate Iran’s production of uranium enriched to close to weapons-grade.
