Report spells out past secret nuclear activities in Iran

VIENNA:

Iran has further stepped up its production of highly enriched uranium, according to a confidential UN nuclear watchdog report, as Foreign Minister Abbas Araghchi said Saturday that Tehran deems nuclear weapons "unacceptable".

According to the latest report by the International Atomic Energy Agency (IAEA) seen by AFP, Iran has sharply increased its stockpile of uranium enriched to up to 60 percent, close to the roughly 90 percent level needed for atomic weapons.

It said in its quarterly report that Iran has an estimated amount of 408.6 kilogrammes enriched to up to 60 percent as of May 17, up by 133.8 kilogrammes since the last report in February.

Iran's total amount of enriched uranium now exceeds 45 times the limit authorised by the 2015 agreement with world powers, and is estimated at 9,247.6 kilogrammes.

"The significantly increased production and accumulation of highly enriched uranium by Iran, the only non-nuclear weapon State to produce such nuclear material, is of serious concern," the IAEA said.

In a separate in-depth report, the IAEA criticised "less than satisfactory" cooperation from Tehran over its scrutiny of its nuclear programme, specifically noting Iran's lack of progress in explaining nuclear material found at undeclared sites.

The report comes as Tehran pursues delicate negotiations with the United States on its nuclear programme.
