Iran exceeded a soft limit on its stock of heavy water, according to a confidential report by the International Atomic Energy Agency (IAEA) seen by Reuters.  The IAEA reported that Iran had 130.1 tonnes of heavy water on November 8, just above the 130-tonne threshold set by the multilateral nuclear agreement.  Iran told the IAEA that it planned to export 5 tonnes of heavy water, as allowed by the agreement.  This is the second time Iran has exceeded the heavy water threshold since the deal was implemented in January.
