IAEA: Iran's Heavy Water Stock Exceeds Authorized Limit Agence France-Presse VIENNA - The U.N.'s nuclear watchdog said Monday that Iran's stock of heavy water for reactors has surpassed the limit set under its agreement with world powers. The International Atomic Energy Agency said in a statement that Iran's heavy water production plant was in operation and that its stock of heavy water reserves was 131.5 tons, above the 130-ton limit. "On 17 November, the Agency verified that the Heavy Water Production Plant (HWPP) was in operation and that Iran's stock of heavy water was 131.5 metric tonnes," an IAEA spokesperson said. It was the first time the agency has recorded a volume greater than the level agreed upon as part of the Joint Comprehensive Plan of Action (JCPOA) reached in 2015 with Britain, China, France, Germany, Russia, the United States and the European Union.
