Heavy water: Proliferating reactors:
Iran is building a small heavy water reactor at Arak, capable of producing 50MW of power. The IAEA withdrew their support from the project in 2006. Heavy water reactors are powered by natural uranium and do not require uranium enrichment. These are the method of choice for producing weapons-grade plutonium. This reactor is still in construction . AIEA inspections are limited. There are suspicions that the purpose of this reactor , foreseen to operate in 2012, will be military.
