April 9, 2012: U.S. Intelligence Estimates and the Iranian Nuclear Program
Recent media reporting about the U.S. intelligence findings on Iran’s nuclear weaponization program has focused on the relatively narrow technical question of whether the Iranian regime has made the decision to restart an effort to actually build nuclear weapons. The recent reporting shows that the U.S. intelligence community assesses that this decision on restart has not yet been made. However, this reporting does not address the broader question of whether Iran decided many years ago to seek nuclear weapons and put in place specific nuclear capabilities to allow it to do so expeditiously.
The activities of Department 70 are in stark contrast to Iran’s declarations. Iran needs to reopen its discussions with the IAEA about procurements related to the PHRC and its activities.

The report includes several new findings regarding the progress of the Iranian program and details the continuing challenges faced by the IAEA.
Iran illicitly targets U.S. military technology for procurement both because of its high quality and Iran’s need for specialized replacement components for existing aircraft programs dating to the Shah’s reign in the 1970s. Two recent cases of Iranian procurement of controlled U.S. aircraft parts illustrate the difficulty of detecting and preventing such activities.

February 11, 2009: Is Iran running out of yellowcake?
Iran could be close to exhausting its supply of yellowcake while lacking the adequate resources to sustain indigenous commercial-scale uranium processing and enrichment. Our conclusion, echoed in a recent report by Mark Hibbs in Nuclear Fuel,1 is based on an examination of Iran’s uranium reserves, its stocks of yellowcake, or uranium oxide, acquired from overseas sources and, the requirements to sustain a commercial nuclear power program. The absence of activity at one of Iran’s two uranium mines casts further doubt on its claims that it can establish independence in the fuel cycle required for a civil nuclear energy program.
February 5, 2009: No progress on diplomatic next steps
January 28, 2009: A Company’s Discretion Detects Large Iranian Valve Orders
In this case, a company used its knowledge about its products’ end uses as well as its expertise in identifying suspicious equipment requests to detect Iranian attempts to procure a large number of valves for its gas centrifuge program. The illicit procurement agents requested items not on international control lists of dual-use items, hoping to evade detection while still obtaining equipment adequate for use in a gas centrifuge uranium enrichment plant.
January 21, 2009: Nuclear Iran: Not Inevitable
Few foreign policy and national security issues have dominated debate in the United States and abroad as Iran’s nuclear program has. Is its declared civil uranium enrichment program a cover for an effort to secretly build nuclear weapons? What should be done to stop Iran from developing a capability to build nuclear weapons? The Obama administration faces a formidable and urgent challenge to sculpt a policy that can convince Iran to abandon or defer a nuclear weapons capability. This report seeks to answer several key questions about how much Iran has achieved. It also offers a roadmap for resolving the nuclear issue both peacefully and in a manner that would redirect Iran away from proliferation-sensitive parts of the fuel cycle, in particular uranium enrichment, while strengthening international monitoring of its nuclear capabilities. Part I of this report contains an overview of Iran’s uranium enrichment program with an emphasis on questions related to Iran’s nuclear weapons capability, including when it might achieve such a capability and the state of evidence suggesting research and development of a weapons program. Part II looks to the recent nuclear histories of Pakistan and South Africa as possible futures for Iran’s nuclear program and draws out key lessons from those experiences. Part III offers a detailed set of recommendations and specific steps that the incoming administration should consider as it seeks to confront the specific challenges posed by Iran’s nuclear program in a wider context of competing regional political and security concerns.
December 19, 2008: What do Juicy Couture and Iran’s nuclear program have in common?
The report makes three points: Iran continues to make progress on developing and operating its centrifuges and plans to significantly increase the number of operational centrifuges; it has refused to allow the IAEA access to the Arak heavy water reactor that is under construction; and continues to resist efforts to address substantively its alleged nuclear weapons-related work, which the IAEA says remains of serious concern.
This report examines future Middle East reactor projects and the large quantities of plutonium in spent fuel expected to accumulate from reactor operations. Since Iran’s nuclear progress could cause other nations to consider their options, several steps must be taken now to prevent proliferation from occurring in the region.
