We, the governments of France, Germany, the United Kingdom and the United States, take note of the report by the International Atomic Energy Agency (IAEA) that Iran has implemented a substantial change in the configuration of some of its centrifuges without informing the Agency in advance. These centrifuges produce high-enriched uranium up to 60% and are located at the Fordow Enrichment Plant.
As stated by the Agency, this unnotified change is inconsistent with Iran’s obligations under its NPT-required Comprehensive Safeguards Agreement. Such lack of required notification undermines the Agency’s ability to maintain timely detection at Iran’s nuclear facilities. The newly reported change in configuration of centrifuge cascades used to produce near-weapons-grade uranium underscores the need for Iran to meet all its safeguards reporting obligations and to accept whatever safeguards monitoring the IAEA sees as necessary in light of Iran’s production of such highly enriched uranium.
Iranian claims that this action was carried out in error are inadequate. We judge Iran’s actions based on the impartial and objective reports of the IAEA, not Iran’s purported intent.
We recall that the production of high-enriched uranium by Iran at the Fordow Enrichment Plant carries significant proliferation-related risks and is without any credible civilian justification.
Iran’s actions are all the more concerning since it has stopped the implementation of its commitments on transparency and verification under the JCPOA, including implementation of its Additional Protocol, for close to two years. Iran has also offered no credible answer yet to the IAEA’s outstanding questions as part of the IAEA’s safeguards investigation, despite the adoption of two resolutions on this issue by the Board of Governors last year.
We call on Iran to comply with all its legally-binding international obligations under its Comprehensive Safeguards Agreement with the IAEA and to fully cooperate with the Agency in the application of effective safeguards at Fordow.
