Isfahan Uranium Conversion Facility
Isfahan Uranium Conversion Facility is a conversion facility operated by Atomic Energy Organization of Iran in Iran. It has a capacity of 200 tU/yr as UF6 as of 2004, about 0% of world conversion capacity.
Iran's conversion plant, under IAEA safeguards since it started up in 2004 and the reason Iran has a fuel chain of its own rather than an enrichment plant with nothing to feed it. Its status is recorded as uncertain because the IAEA has had no access to any safeguarded facility in Iran since 13 June 2025, following military strikes on Iranian nuclear sites that month, and has received no material accountancy reports since. Nothing about its current condition can be stated from the public record.

At the market indicator. 200 tU/yr of nameplate capacity, valued at US$ 65.00 per kgU spot, comes to roughly US$ 13 million a year, or US$ 11 million at the long-term indicator. Treat both as scale, not revenue: most volume moves under contracts signed years earlier at prices neither figure reflects, and nothing here is netted against the cost of producing it. The indicators, and forty years of history behind them, are on fuel market prices.
