Iran's stock of uranium enriched to near weapons-grade has shrunk slightly as it diluted some but long-standing problems between Iran and UN inspectors are festering, confidential reports by the UN nuclear watchdog on Monday showed.
Iran diluted, or downblended, 31.8 kg of uranium enriched to up to 60% to produce 97.9 kg of uranium enriched to up to 20%, one of the two quarterly International Atomic Energy Agency reports to member states seen by Reuters said. The total stock at 60%, close to the 90% of weapons-grade, was estimated to have shrunk by 6.8 kg to 121.5 kg over the quarter.
