Three months ago, it started enriching to that level at a second site, Fordow, which is dug into a mountain. Weapons grade is around 90 percent.
“So far, we have not made any attempt to enrich above 60 percent. The presence of particles above 60 percent enrichment does not mean production with an enrichment above 60 percent,” the spokesperson for Iran’s Atomic Energy Organization, Behrouz Kamalvandi, said on Monday, according to the official IRNA News agency.
Bloomberg News reported on Sunday that UN nuclear watchdog monitors had last week detected uranium enriched at 84 percent.
Kamalvandi called the report “slanderous” and said it distorted facts.
