Iran Conflict 2026Mentioned in: Fordow inoperable since June 2025 bunker-busters
Iran Conflict 2026- What did the IAEA find out about Fordow after the US strikes on Iran?
- The IAEA's 6 April 2026 update, relayed by the American Nuclear Society, confirmed Fordow remained intact and inoperable after US bunker-busters struck it in June 2025. Fordow was not retargeted in the February 2026 campaign. No inspectors have verified current status since the Majlis expelled them on 11 April 2026.Source: IAEA / American Nuclear Society
- What is the American Nuclear Society?
- A US professional organisation of roughly 10,000 nuclear scientists and engineers, founded in 1954, that publishes Nuclear News and technical journals. It is not a government or regulatory body. In the Iran conflict it has served as a technical relay for IAEA assessments on damaged nuclear facilities.Source: ANS
- Can the nuclear science community verify Iran's enrichment capacity without IAEA inspectors?
- With direct IAEA access suspended since April 2026, open-source analysis of satellite imagery (by organisations such as ISIS, directed by David Albright) and technical relays by bodies like the American Nuclear Society are now the primary non-governmental sources of information on Iranian facility status.Source: IAEA / ANS
Background
The American Nuclear Society (ANS) is a US professional organisation of approximately 10,000 nuclear scientists, engineers, and technologists, founded in 1954. It publishes Nuclear News, Nuclear Technology, and other peer-reviewed journals. ANS has relayed IAEA technical findings on Iranian nuclear facilities throughout the conflict period, beginning with damage assessments after the June 2025 Twelve-Day War (Operation Rising Lion and Operation Midnight Hammer) and continuing through the 2026 campaign. Its Nuclear News publication functions as a credentialed engineering-community relay for IAEA board reports and Director General statements that may not reach general audiences.
In Lowdown coverage, ANS most prominently appeared relaying the 6 April 2026 IAEA update (briefing #72) that Fordow remained intact and inoperable after June 2025 and had not been retargeted in the 2026 campaign. That update was part of an ongoing monitoring series rather than an isolated finding; ANS had been tracking IAEA statements on Natanz, Esfahan, and Fordow since the June 2025 strikes. After the Iranian Majlis voted 221-0 on 11 April 2026 to suspend all IAEA cooperation, ANS's relay of pre-expulsion data became the last credentialed technical record of site status before the programme went dark.
The ANS is headquartered in La Grange Park, Illinois, and is entirely distinct from governmental or regulatory bodies. Its members include staff at national laboratories (Los Alamos, Livermore) and university research reactors. ANS takes no policy positions on the use of nuclear weapons; its role in this coverage is strictly as a technical intermediary translating IAEA engineering-level findings for practitioners and a wider public. Its non-governmental status gives it modest credibility with audiences sceptical of official US or IAEA framing.
