The IAEA has concluded that “these three locations, and other possible related locations, were part of an undeclared structured nuclear programme carried out by Iran until the early 2000s and that some activities used undeclared nuclear material”, the report said.
Nuclear material and/or heavily contaminated equipment from that programme was stored at the fourth site, Turquzabad, between 2009 and 2018, it said.
“The Agency concludes that Iran did not declare nuclear material and nuclear-related activities at three undeclared locations in Iran, specifically, Lavisan-Shian, Varamin, and Turquzabad,” the report said.
At Lavisan-Shian in Tehran, a disc made of uranium metal was “used in the production of explosively-driven neutron sources” at least twice in 2003, a process designed to initiate the explosion in a nuclear weapon, the report said, adding that it was part of “small-scale” tests.
The report is likely to lead to Iran being referred to the UN Security Council, though that would probably happen at a later IAEA board meeting, diplomats said.
More immediately, it is likely to lead to Iran again accelerating or expanding its rapidly advancing nuclear programme, as it has done after previous rebukes at the board. It could also further complicate talks with the United States aimed at reining in that programme.
URANIUM ENRICHMENT
A separate IAEA report sent to member states on Saturday (May 31) said Iran’s stock of uranium enriched to up to 60 percent purity, close to the roughly 90 percent of weapons grade, had grown by roughly half to 408.6 kg. That is enough, if enriched further, for nine nuclear weapons, according to an IAEA yardstick.
