Nigeria's Miniature Neutron Source Reactor was the last operational research reactor in Africa to make the conversion from HEU to LEU. Here, the HEU once used in the reactor is loaded for shipment back to China, the supplier (IAEA).

Securing Nuclear Weapons and Materials Worldwide: Expanded Funding Needed for a More Ambitious Approach

| Apr. 19, 2019

The Trump administration budget request for programs to reduce the dangers of nuclear theft and terrorism is too small to implement the ambitious approach that is needed. Congress should increase funding in this critical area; direct the administration to develop and implement a comprehensive plan for improving security for nuclear weapons and materials worldwide; and exert expanded oversight of this effort. This brief highlights the importance of ongoing nuclear security work; describes the evolving budget picture; and outlines recommendations for congressional action.

A Better Way to Confront Russia's Nuclear Menace

| Oct. 28, 2018

Ongoing Russian violations of the Intermediate Range Nuclear Forces (INF) Treaty need to be effectively addressed because they defy a longstanding bilateral agreement and directly threaten our NATO allies. However, the Trump administration’s move to pull out of the treaty is misguided; instead, we should launch a major initiative to strengthen strategic stability between the United States and Russia, writes Elizabeth Sherwood-Randall.

Iran Stockpiling Uranium Far Above Current Needs

| January 10, 2017

In a televised speech on January 1, Iranian President Hassan Rouhani said that Tehran had imported 200 metric tons of yellowcake uranium and would import another 120 tons at an unspecified future date. The imports are permitted by the nuclear deal, the Joint Comprehensive Plan of Action (JCPOA), but nonetheless significantly exceed Iran’s needs for natural (that is, unenriched) uranium over the next 15 years. Iran’s import of such high levels of uranium suggests it may be stockpiling uranium to reach nuclear breakout before the deal’s initial limitations expire in 2031.

The JCPOA permits Iran to buy natural uranium to “replenish” its stocks as it sells enriched uranium on the international market. To date, Iran has had difficulties locating a buyer for its enriched uranium stocks – unsurprising, given the current excess of commercially available enriched uranium. This, however, has not stopped Iran from buying and stockpiling more yellowcake.

China’s Nuclear Security: Progress, Challenges, and Next Steps

| March 28, 2016

In a new report from the Project on Managing the Atom, Senior Research Associate Hui Zhang finds that China has made important nuclear security improvements in areas ranging from its legal framework, to its approaches to physical protection and material accounting, to bolstering nuclear security culture. But China also faces ongoing threats. The possibility of insider theft of nuclear materials in China cannot be ruled out, espe­cially as China increasingly grows into a market-oriented society contending with corruption. Zhang also notes that Beijing faces a growing terrorism threat from separatists in China’s autonomous Xinjiang region.

Two Recent Incidents of Insecurity

| July 21, 2015

Are nuclear sites secure?  There are some who might assume the answer is yes and that we should not worry about the possibility of nuclear bomb material being stolen. Yet, recent history has repeatedly demonstrated that high security facilities thought to be secure were actually vulnerable. Two such incidents last month illustrated this idea.

IAEA Releases Guidelines on Nuclear Material Control and Accounting

| June 09, 2015

More than a decade after its nuclear security recommendations first recognized the threat insiders pose to nuclear facilities, the International Atomic Energy Agency (IAEA) has finally released its guide on nuclear material control and accounting for nuclear security.  (This has been in the works for years.) Many people wrongly think that any material under international safeguards has accounting and control good enough for security purposes as well, but there are important differences.

Why Security Fails

| Feb. 11, 2015

In thinking about how nuclear security and safeguards can fail, it is useful to keep in mind why security usually fails in general.  Most security managers and organizations have a good understanding of the assets they are trying to protect, the resources available to them to protect those assets, and the consequences should security fail (though this is sometimes greatly underestimated).  They often have a reasonably accurate understanding of the threats they face—who might attack, why, how, when, and with what goals and resources.  What is often lacking is a good understanding of the vulnerabilities—the weaknesses in the security that can be exploited by the threats—and how those vulnerabilities can be mitigated or eliminated.

Belfer Experts: The End of U.S.–Russian Nuclear Security Cooperation?

Jan. 21, 2015

More than two decades of U.S.-Russian cooperation to keep potential nuclear bomb material out of terrorist hands largely came to an end last month, as The Boston Globe reported Monday. Although the dangers have not gone away, Russia is no longer interested in working on most nuclear security projects with the United States— yet another victim of increasing tension between the two countries. The Belfer Center has been centrally involved in these efforts since their inception. Belfer Center experts Graham Allison, Matthew Bunn, and William Tobey offer their thoughts.
