Iran Could Have Bomb in a Month: Report But negotiators point to progress in talks By Matt Cantor, Newser User Posted Oct 25, 2013 12:17 AM CDT Updated Oct 25, 2013 5:33 AM CDT 45 comments Comments In this Aug. 15, 2013 file photo, Iranian President Hasan Rouhani speaks at parliament in Tehran. (AP Photo/Ebrahim Noroozi, File) (Newser) – In just a month, Iran could have enough weapons-grade uranium to build a nuclear bomb, a US expert says. "Breakout times"—a reference to the period needed to get weapons-grade uranium from low-enriched uranium—"are currently too short and shortening further." The findings, from the Institute for Science and International Security, are based on Iranian and UN data on nuclear progress, USA Today notes. The White House is currently urging Congress to hold off on potential tougher sanctions on the country. Meanwhile, however, some US officials say new nuclear talks with Iran are going well. "I have never had such intense, detailed, straightforward, candid conversations with the Iranian delegation before," says a negotiator, per the Christian Science Monitor. Indeed, an Iranian lawmaker says the country isn't currently enriching uranium to 20% purity, a point at which it's easy to make weapons-grade stuff, the Monitor notes. MP Hossein Naqavi Hosseini says there's "no need for further production" of 20%-enriched uranium, the Telegraph reports. Such a halt is one of the West's central goals in negotiations, the Monitor reports. Hosseini, however, isn't a government spokesman or nuclear negotiator, the AP notes.
