IAEA Director General Rafael Grossi made public statements about Iran’s enriched uranium stockpile in an interview with the French TF1 published on February 18, 2026. Here is the relevant part of his interview.
[L]a plupart du matériel que l'Iran avait accumulé jusqu'au mois de juin de l'année dernière, malgré les bombardements, malgré les attaques, est toujours là, dans la plus grande quantité, où il se trouvait au moment des attaques. Et donc, il y a une partie qui est peut-être moins accessible, mais le matériel, est toujours là. Donc, d'un point de vue de non-prolifération, le matériel est toujours là.
{O]n sait exactement où le matériel était stocké. Et si on n'a pas pu accéder aux installations depuis la guerre, on a fait une évaluation assez exacte des dégâts. Et on sait que le matériel était là et qu'il était protégé. Donc, pour la plupart, il est toujours là.
Perhaps one should not take his remarks too literally, since as IAEA DG, he would only have been briefed by the responsible safeguards experts. But what he said was:
• IAEA knew ‘exactly’ where the enriched uranium was (and how much) on June 13 when Israel started the war.
• IAEA has not visited the bombed sites.
• IAEA has done a rather exact evaluation of the damage, which supports the conclusion that most of that material remains where it was “at the moment it was attacked.” A part of it may be less accessible, due to the attack, but it is still there.
That does not give the full picture. Israel did not bomb Fordow, which is where much of the stockpile was on June 13. The US used bunker busters on Fordow on June 21. Satellite imagery showed significant movement of transport vehicles at the entrance to Fordow between June 13 and June 21. There have been a few statements by Iranian officials that material was moved before the US bombing. Grossi used the phrase “at the moment it was attacked,” which means June 21, not June 13. So, IAEA believes that what was at Fordow on June 21 is still there. If material was moved, then it is somewhere else. How much and where are not publicly known.
Then there is the tunnel complex at Isfahan. Israel bombed some facilities at Isfahan but left the deep underground tunnel complex to the US. On June 21, the US bombarded the entrances to that tunnel complex with Tomahawk missiles. Inside was too deep for even the bunker busters to reach. There has been speculation that material from Fordow was moved to the Isfahan tunnel complex between June 13 and June 21. If so, it is still there. Very recently, Iran has completely covered the entrances with lots of dirt, in preparation for more attacks by the US and Israel.
There has been mention of transferring enriched uranium out of Iran, as part of a deal, and Russia has expressed its readiness to accept such material. What that would involve would be transport of the UF6 cylinders in which the enriched UF6 is stored (in solid form). Those cylinders would come from Fordow, Isfahan and a few from Natanz. That suggests that some UF6 cylinders are intact after the 12-day war. Which ones and where is not public knowledge.
