An Important Step on the Way to the Bomb
"In a report issued last May, the IAEA complained that despite its commitment in 2003 and the UN Security Council resolutions notwithstanding, Iran has not yet suspended the heavy water reactor project, as it has not suspended the uranium enrichment project. Moreover, since 2006, Iran has not provided the IAEA with the complete design data of the reactor, as it was required to do according to the IAEA code.

Additionally, Iran continues to prevent the IAEA from inspecting the heavy water production plant, also located in Khondab. The capacity of this plant is 16 tons of heavy water per year. The reasoning for this state of affairs is a formal one: in Iran's opinion, heavy water is not a controlled nuclear material, as it is not a fissionable material like uranium or plutonium, and is not even radioactive."
