The Iran Nuclear Archive: Impressions and Implications

In mid-January, a team of scholars from the Belfer Center’s Intelligence and Managing the Atom Projects traveled to Tel Aviv, Israel to examine samples of, and receive briefings on, an archive of documents related to Iran’s nuclear weapons program. The large cache includes some 55,000 pages of documents and a further 55,000 files on CDs that included photos and videos. A clandestine Israeli intelligence operation spirited the materials out of Iran in early 2018.

The documents that the Belfer group were shown confirm that senior Iranian officials had decided in the late 1990s to actually manufacture nuclear weapons and carry out an underground nuclear test; that Iran’s program to do so made more technical progress than had previously been understood; and that Iran had help from quite a number of foreign scientists, and access to several foreign nuclear weapon designs. The archive also leaves open a wide range of questions, including what plan, if any, Iran has had with respect to nuclear weapons in the nearly 16 years since Iran’s government ordered a halt to most of the program in late 2003. 

This brief report summarizes the group’s conclusions about what the archive reveals about Iran’s program and questions that remain open.

Revitalizing Nuclear Security in an Era of Uncertainty

| January 2019

Nuclear security around the world has improved dramatically over the last three decades—which demonstrates that with focused leadership, major progress is possible. But important weaknesses remain, and the evolution of the threat remains unpredictable. The danger that terrorists could get and use a nuclear bomb, or sabotage a major nuclear facility, or spread dangerous radioactive material in a “dirty bomb,” remains too high. The United States and countries around the world need to join together and provide the leadership and resources needed to put global nuclear security on a sustained path of continuous improvement, in the never-ending search for excellence in performance.

Steps for Rebuilding U.S.-Russian Nuclear Security Cooperation

| July 2017

Cooperation between U.S. and Russian nuclear scientists and engineers represents an important opportunity for rebuilding U.S.-Russian relations. The United States and Russia possess more than 90 percent of the world’s nuclear weapons, the world’s largest stocks of weapons-usable nuclear material, and the world’s largest nuclear complexes, giving them a special responsibility for nuclear security and preventing nuclear terrorism.

When Did (and Didn’t) States Proliferate?

| June 2017

In this Project on Managing the Atom Discussion Paper, Philipp C. Bleek chronicles nuclear weapons proliferation choices throughout the nuclear age. Since the late 1930s and early 1940s, some thirty-one countries are known to have at least explored the possibility of establishing a nuclear weapons program. Seventeen of those countries launched weapons programs, and ten acquired deliverable nuclear weapons.

Is Iran Mass Producing Advanced Gas Centrifuge Components?

| May 30, 2017

The head of Iran’s nuclear program says Iran has the capability to initiate mass production of advanced centrifuges on short notice. The mass production of these centrifuges (or their components) would greatly expand Iran’s ability to sneak-out or breakout to nuclear weapons capability or surge the size of its centrifuge program if the deal fails or after key nuclear limitations end. If Salehi’s statement is true, Iran could have already stockpiled many advanced centrifuge components, associated raw materials, and the equipment necessary to operate a large number of advanced centrifuges. The United States and the International Atomic Energy Agency (IAEA) need to determine the status of Iran’s centrifuge manufacturing capabilities, including the number of key centrifuge parts Iran has made and the amount of centrifuge equipment it has procured. They need to ensure that Iran’s centrifuge manufacturing is consistent with the intent of the nuclear deal as well as the deal’s specific limitations on advanced centrifuges. Moreover, the Iranian statement illuminates significant weaknesses in the Iran deal that need to be fixed.

Iran and a New International Framework for Nuclear Energy

| November 2016

As early as the end of the Second World War it was recognized that nuclear fuel cycle technologies developed for military purposes—specifically, uranium enrichment and reprocessing—had major potential for peaceful applications but remained inherently dual-purpose, and if not controlled appropriately, could be diverted to military use. The very first issue considered by the newly founded United Nations was “the problems raised by the discovery of atomic energy.”

Preventing Nuclear Terrorism: Continuous Improvement or Dangerous Decline?

In this new report, Preventing Nuclear Terrorism: Continuous Improvement or Dangerous Decline?, Matthew Bunn, Martin Malin, Nickolas Roth, and William Tobey provide a global reality check on nuclear security. They note that effective and sustainable nuclear security capable of addressing plausible threats is the single most effective chokepoint preventing terrorists from acquiring a nuclear weapon.

Tipping the Balance?

| December 2015

Standing before the United States Congress early in March 2015, in the face of a looming deadline in the Iran and P5+1 talks over the Iranian nuclear program, Israeli Prime Minister Benjamin Netanyahu portrayed the negotiations in stark terms. Drawing a direct parallel between biblical plots to persecute Jews in pre-Islamic Persia and modern Iran’s nuclear program, Netanyahu framed Iran as nothing less than an existential threat to Israel. Anything short of a practical dismantling of Iranian nuclear infrastructure would be unacceptable. Largely perceived as an attempt to undermine President Barack Obama’s efforts to reach a negotiated settlement with Iran, Netanyahu’s actions thus proved quite contentious inside the United States.

Strengthening the Verification and Implementation of the Joint Comprehensive Plan of Action

| November 16, 2015

The Joint Comprehensive Plan of Action (JCPOA) puts Iran’s nuclear program under greater scrutiny than before and reduces the likelihood of an overt dash to the bomb for the next 10 years. But the agreement contains a number of notable weaknesses—particularly regarding undeclared nuclear activity and weapons- related research—that should be mitigated by adopting stronger verification measures.

International Cooperation to Secure Military Nuclear Materials

| October 7, 2015

"One category of nuclear material that has not yet been adequately addressed throughout recent Nuclear Security Summits is military stockpiles.2 Instead, the Summit process has focused primarily on reducing the risk of civilian nuclear material theft..."
