IAEA inspectors reportedly found 83.7% enriched uranium particles at Iran's Fordow plant in February 2023

In February 2023, IAEA inspectors reportedly discovered uranium particles enriched to 83.7% at Iran's Fordow Fuel Enrichment Plant, according to a Reuters report. The finding was described as near weapons-grade, though Iran denied intentionally enriching to that level. The IAEA later stated that the particles were likely due to unintended fluctuations in enrichment levels. The provided sources do not directly confirm this specific incident, but they do indicate that Iran has produced uranium enriched up to 60% and has amassed significant stockpiles of near-weapons-grade material.
