Iran has the infrastructure and material to produce weapons-grade uranium. It has enough enriched uranium to produce fuel for six nuclear weapons after conversion to weapons-grade levels. Its expanding enrichment activities have significantly reduced the time required for it to produce weapons-grade uranium. The key accelerants for this shrinking timeline have been its growing stockpiles of low- and medium-enriched uranium, which is 90% of the way to weapons-grade uranium, and an increasing number of centrifuges enriching.
