Iran, by comparison, is producing near-weapons-grade uranium, but it also has a heavy-water reactor being developed that could produce weapons-usable plutonium.
The enrichment plants at Natanz, Qom and perhaps elsewhere give Iran an early route to HEU. A planned heavy-water reactor at Arak will produce large quantities of plutonium as a by-product, but will not be completed for some years.
Moreover, between the Russian-built, soon-to-be-opened nuclear reactor in Bushehr and the illicit heavy water reactor in Arak, Iran will have the capacity to build plutonium-based bombs within two years.
