Iran: A secret letter from May 2004 says the heavy water capacity of the Khandab plants far exceeded the claimed 8 tons. The agency's analysis of satellite images and dimensions of the refinery indicated that the plant was designed to supply 100 tons of heavy water over several years. The supervisors used the doctoral thesis of Iranian students to identify the design model of the facilities.
