Not clear yet that Iran has produced any weapons grade fissile material

Myth 4: Iran has sufficient nuclear fuel to make a bomb.
This claim has been advanced by sloppy analysts and others interested in hyping the urgency of an Iranian nuclear threat. However, there is no evidence Iran has produced any weapons-grade fissile material. All publicly available evidence suggests Iran is producing low enriched uranium at roughly the 5 percent and 20 percent levels (for energy pro- duction and medical treatments), but not to the 90 percent level required for weapons-grade fissile material. Moreover, while Iran is openly increasing its capacity to produce more of this low enriched uranium with additional centrifuges, the International Atomic Energy Agency (IAEA) in February and May verified Iran is simultaneously converting some of its enriched uranium to fuel stocks thereby reducing the amount of fissionable material potentially available for a nuclear bomb.18 Iran is, therefore, deliberately limiting the amount of its enriched uranium stocks below that required for a nuclear bomb.
