Vienna, AP, Nov. 9،  2016 – The UN agency monitoring the nuclear pact between Iran and six world powers is reporting that Iran’s stockpile of heavy water is marginally over the allowed limit but Tehran plans to return to compliance.
The deal specifies a heavy water limit of 130 metric tons (143.3 tons.) The confidential report was seen by The Associated Press that was issued Wednesday says that Iran’s stockpile exceeded that amount by 0.10 metric tons.
Heavy water is a potential proliferation concern because it is used in reactors that produce substantial amounts of plutonium, a potential path to nuclear weapons. Iran already overstepped the limit in February when some of the excesses was exported to the US.
