Iran: Interim Nuclear Agreement and Talks on a Comprehensive Accord [March 9, 2015] [open pdf - 379KB]
"On November 24, 2013, Iran and the six powers that have negotiated with Iran about its nuclear program since 2006 (the United States, the United Kingdom, France, Russia, China, and Germany--collectively known as the 'P5+1') finalized an interim agreement ('Joint Plan of Action,' JPA) requiring Iran to freeze many aspects of its nuclear program in exchange for relief from some international sanctions. The period of the interim deal was to be six months, during which time Iran and the P5+1 would attempt to reach a comprehensive deal on the long-term status of Iran's nuclear program. The main elements of the JPA are requirements that Iran freeze, in effect, its production of enriched uranium hexafluoride containing 20% uranium-235--the form of enriched uranium in Iran's stockpile that has caused the most concern; dilute and convert the 20% enriched uranium and 5% enriched uranium stocks to other forms that would take time to reverse; halt key elements of its heavy-water reactor program that could lead to a plutonium bomb; and provide the International Atomic Energy Agency (IAEA) with additional information about its nuclear program, as well as access to some nuclear-related facilities which are not covered by Iran's IAEA safeguards agreement. The JPA has been seen as slowing Iran's build-up of nuclear material and improving the international community's ability to identify Iranian efforts to develop nuclear weapons."
