The United States has cut a deal with Iran to purchase heavy water from the Islamic Republic, according to a report posted on the Hezbollah-linked Al Manar website.
The report quoted PressTV as saying Iran will sell 32 metric tons of heavy water to the U.S.
Heavy water is used in certain types of nuclear reactors, where it acts as a neutron moderator to slow down neutrons so they are more likely to react with the fissile uranium-235 than with uranium-238, which captures neutrons without fissioning.
Iranian Deputy Foreign Minister for Legal and International Affairs, Abbas Araqchi told PressTV in Vienna on Friday the Atomic Energy Organization of Iran reached an agreement on the sale with a U.S. company before a joint commission meeting between Iran and the P5+1 group.
The agreement was reportedly signed following three months of negotiations.
