Iran is endangering support for a landmark deal with major powers by twice overstepping a "soft" limit on sensitive material, the UN nuclear watchdog has warned.
The International Atomic Energy Agency (IAEA) said in a report last week that Iran had slightly exceeded the 130-tonne limit on its stock of heavy water for a second time since the nuclear deal was put in place in January.
The six other countries that signed the deal, including the United States, have been muted in their criticism. But there are questions about how US president-elect Donald Trump, who has strongly criticised the deal and has said he will "police that contract so tough they [the Iranians] don’t have a chance", would handle any similar case once he takes office.
The IAEA chief, Yukiya Amano, told the agency’s board of governors on Thursday that it was "important that such situations should be avoided in future in order to maintain international confidence" in the implementation of the agreement.
A week ago's report said Mr Amano had communicated worries to Iran over its supply of overwhelming water, a material utilized as an arbitrator as a part of reactors, for example, Iran's unfinished one at Arak, which had its center expelled and made unusable under the arrangement.
The worldwide assention places limitations on Iran's nuclear exercises, checked by the IAEA, in return for the lifting of universal approvals.
As opposed to setting a strict breaking point on overwhelming water as it accomplishes for advanced uranium, the arrangement gauges Iran's should be 130 tons and says any sum past its needs "will be made accessible for fare to the universal market"."
Mr Amano said Iran had "made arrangements to exchange an amount of substantial water out of the nation"
"When it has been exchanged, Iran's load of overwhelming water will be beneath 130 metric tons."
