U.N. sees small but significant Iranian nuke deal violation
VIENNA — The United Nations agency monitoring the nuclear pact between Iran and six world powers said Wednesday that Iran is in violation of the deal meant to curb its ability to make atomic arms by storing marginally more heavy water than the agreement allows.
Heavy water is a concern because it is used to cool reactors that can produce substantial amounts of plutonium. That, in turn, can be applied to making the fissile core of nuclear warheads.
The U.N.’s International Atomic Energy Agency said in a confidential report obtained by The Associated Press that Iran had exceeded the heavy water allotment of 143.3 tons only slightly — by 220 pounds. The report also noted that Iran had served notice it would resolve the issue by exporting 5 metric tons, substantially over the excess amount.
