It is the second time that Iran has surpassed the 130 metric tonne threshold for heavy water, a material used as a moderator in reactors, such heavy water facility at Arak. The UN nuclear watchdog stated that it had 130.1 tonnes of the material on Tuesday.
The last time Iran overstepped the limit was reported to be brief, passing without major criticism P5+1 nations.
The IAEA is monitoring the restrictions placed on Iran’s nuclear activities under the deal it signed with the P5+1 (United States, Russia, China, Britain, France and Germany).
The agreement, which came into effect in January, lifted international sanctions against Tehran, has led to the country securing access to more than $100 billion from the relief. Many believe that the relief has empowered Iran’s hardliners and will help fund its regional hegemonic ambitions.
Iran told the agency it would prepare to transfer five tonnes of heavy water out of the country, as provided for in the deal, and a senior diplomat said Iran planned to carry out the shipment in the coming days.
Since the signing of a formal nuclear agreement between Iran and the P5+1 in July 2015, Iran has increased the frequency of ballistic missile testing, launching eight missiles in the past year.
