Iran has started work on uranium metal-based fuel for a research reactor, the United Nations’ nuclear watchdog and Tehran said on Wednesday, in the latest breach of its nuclear deal with six significant powers as the country presses for a lifting of US sanctions.
Kazem Gharib Abadi, Iran’s representative at the International Atomic Energy Agency (IAEA), confirmed the country has started working on the fuel, saying everything has been reported to the agency.

“Agency inspectors visited the factory where the fuel will be produced three days ago,” he said.
“From a technical standpoint, this puts Iran among advanced countries in producing new fuels.”
Iran has been accelerating its breaches of the deal in the past two months. Some of those steps were required by a law passed in response to the killing of its top nuclear scientist in November, which Tehran has blamed on its arch foe Israel.
They are also, however, part of a process started by Tehran in 2019 of committing breaches in response to US President Donald Trump’s 2018 withdrawal from the deal and his reimposition of US sanctions that the deal lifted in exchange for restrictions on the country’s nuclear activities.
The moves raise pressure on US President-elect Joe Biden, who takes office next week and has pledged to return the US to the deal if Iran first resumes full compliance. Iran wants Washington to lift sanctions first.
“[IAEA] Director General Rafael Mariano Grossi today informed IAEA Member States about recent developments regarding Iran’s plans to conduct R&D activities on uranium metal production as part of its declared aim to design an improved type of fuel for the Tehran Research Reactor,” the IAEA said in a statement.
The agency issues ad hoc reports to member states when Iran commits a new breach of the deal, though it declines to call them breaches, leaving that call to parties to the 2015 accord.
The deal specifically imposes a 15-year ban on Iran producing or acquiring uranium metal, a sensitive material that can be used in the core of a nuclear bomb.
The IAEA’s confidential report to member states, obtained by Reuters news agency, said Iran had indicated it plans to produce uranium metal from natural uranium and then produce uranium metal enriched up to 20 percent for fuel for the Tehran Research Reactor.
The deal also says that can only happen in small batches and in consultation with parties to the deal after 10 years.
Separately, Iran also plans to enrich uranium to 20 percent, a level it last reached before the 2015 deal, at its Fordow site buried in a mountain, and it started that process last week.
It had so far only gone as far as 4.5 percent, above the 3.67 percent limit imposed by the deal but still far short of the 90 percent that is weapons grade.
US intelligence agencies and the IAEA believe Iran had a secret, coordinated nuclear weapons programme that it halted in 2003. Iran denies ever seeking nuclear weapons and says its aims with nuclear energy are entirely peaceful.
Iran told the agency on Wednesday, however, that “there is no limitation on [its] R&D activities” and “modification and installation of the relevant equipment for the mentioned R&D activities have been already started” at its Fuel Plate Fabrication Plant in Isfahan, the IAEA report said.
