Iran said it would restart production of fuel for its Tehran Research Reactor, a facility that runs on uranium enriched to higher levels to produce medical isotopes.<br/> International Atomic Energy Agency inspectors in Iran were told of the country's plans, according to a statement on Twitter by the country's envoy, which was confirmed by semi-official Tasnim news agency. The Vienna-based IAEA confirmed that it had received the information. Iran's move is part of a broad suite of measures recently passed by the country's parliament to accelerate nuclear activities <a href="https://www.thenationalnews.com/world/the-americas/us-sanctions-two-khamenei-foundations-in-latest-pressure-on-iran-1.1145736">in response to US sanction</a>s. The country said it is prepared to roll back those moves once trade restrictions are lifted. President-elect Joe Biden is expected to reassess the US relationship with Iran after taking office later this month.<br/> A decision to turn its stockpile of 20 per cent-enriched uranium into metal plates for its research reactor would make it more difficult for Iran to further purify the material into weapons-grade materiel. The accumulation of enriched uranium is a long-standing concern among Iran's neighbours in the Arabian Gulf. The country's stockpile has swelled more than 10-fold after President Donald Trump's 2018 decision to jettison an international accord exchanging sanctions relief for nuclear restrictions. <br/> This month, the Iranian government confirmed it was implementing an "anti-sanctions" law, ratified in December, reviving and promoting certain atomic activities to build pressure on the incoming Biden administration to lift key sanctions.<br/> A January 4 statement on the government's official website, dolat.ir, said that the Atomic Energy Organisation of Iran would also take steps to establish a uranium metal production facility in Esfahan and "aim to have it operational" within months, as part of that law.
