Russia and the Global Nuclear Order

| March 2024

Russia's 2022 invasion of Ukraine illuminated the long profound shadow of nuclear weapons over international security. Russia's nuclear threats have rightfully garnered significant attention because of the unfathomable lethality of nuclear weapons. However, the use of such weapons in Ukraine is only one way—albeit the gravest— that Russia could challenge the global nuclear order. Russia's influence extends deep into the very fabric of this order—a system to which it is inextricably bound by Moscow's position in cornerstone institutions such as the Nuclear Non-Proliferation Treaty (NPT) and the International Atomic Energy Agency (IAEA). From withdrawing from key treaties to stymieing resolutions critical of misconduct, Moscow has demonstrated its ability to challenge the legitimacy, relevance, and interpretations of numerous standards and principles espoused by the West.

How to Ensure Iran Never Resumes Reprocessing

| Dec. 13, 2017

Though the negotiation leading to the JCPOA took place over a significant stretch of time—indeed, it was built on the foundation of talks that began in 2003—it’s important to remember that the deal contains critical concessions regarding Iran’s production of plutonium, which the United States had been seeking from Tehran since the 1970s, when the two countries were allies.

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.

The Nuclear Security Summit and the IAEA: Advocating Much and Avoiding Specifics

| Apr. 08, 2016

The 2016 Nuclear Security Summit (NSS) in Washington D.C. on 1 April issued a seven-page Action Plan in Support of the International Atomic Energy Agency (IAEA). It contains steps that the summit participants commit themselves to taking and those they “advocate” the Agency “pursue”. In endorsing this plan, 2016 Summit participants focused more detailed attention on the IAEA than those who participated in the previous four nuclear security summits.

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.

How Nuclear Material Accounting Can Contribute to Nuclear Security

May 16, 2014

Like its predecessor summits, the recently concluded Nuclear Security Summit in The Hague acknowledged the role that nuclear material accounting can play in securing materials from unauthorized use. The emphasis of this and past initiatives, however, has been on improving national laws and regulations—and primarily in states without nuclear weapons. States have yet to develop comprehensive requirements that address the full scope of nuclear risks and that are meant to be adopted by all states—including nuclear weapons states.
