That is the same time frame that existed before President Barack Obama struck the nuclear deal. That, however, is only the first step because the fuel would have to be turned into a weapon. When the deal was struck, Iran had roughly 22,000 pounds of low-enriched uranium on hand, the kind used for powering nuclear reactors. That is why it would probably take Iran a long while to resume production: It does not have the uranium needed to keep a larger number of centrifuges running. And the Iranians have already made clear they have little interest in bringing back their old, inefficient centrifuges.
