Iran's Nuclear Program: Tehran's Compliance with International Obligations [January 14, 2016] [open pdf - 653KB]
"The U.N. Security Council has required Iran to cooperate fully with the International Atomic Energy Agency's (IAEA's) investigation of its nuclear activities, suspend its uranium enrichment program, suspend its construction of a heavy-water reactor and related projects, and ratify the Additional Protocol to its IAEA safeguards agreement. However, Tehran has continued to defy the council's demands by continuing work on its uranium enrichment program and heavy-water reactor program. Iran has signed, but not ratified, its Additional Protocol. Tehran has limited and reversed some aspects of these programs' progress since the government began implementing a November 2013 Joint Plan of Action between Iran and China, France, Germany, Russia, the United Kingdom, and the United States. [...] This report provides a brief overview of Iran's nuclear program and describes the legal basis for the actions taken by the IAEA board and the Security Council. It will be updated as events warrant."
