It is well-known that Iran has enriched Uranium to 60%, much more than the 5% which is commonly required for nuclear reactors, and also more than the 20% required by some specialized reactor designs. Iran has clearly tried to position itself as a 'threshold nuclear power', as enriching to 90% (from 60%) is relatively quick and easy. https://world-nuclear.org/information-library/nuclear-fuel-cycle/conversion-enrichment-and-fabrication/uranium-enrichment https://world-nuclear.org/information-library/nuclear-fuel-c... https://en.wikipedia.org/wiki/Nuclear_program_of_Iran https://en.wikipedia.org/wiki/Nuclear_program_of_Iran
