Nuclear Issues

This week the National Nuclear Security Administration (NNSA) announced that 546 kilograms of plutonium and highly enriched uranium (HEU) shipped from Japan arrived in the United States.

In mid-July, as an attempted coup was taking place in Turkey, many in the United States wondered whether U.S. tactical nuclear weapons stored at the Turkish airbase, Incirlik, were adequately protected against theft. Congressional Research Service Nuclear Weapons Policy Specialist, Amy Woolf, recently published a short article describing some of the security systems surrounding those weapons.

The just-concluded fourth and final nuclear security summit saw some serious progress, but also some missed opportunities.

Fifty-plus countries are attending the 2016 Nuclear Security Summit this week in Washington, DC. Notably missing from the guest list is Iran, whose recent negotiation and implementation of a landmark nuclear deal with the P5+1 led some experts to call for more engagement and cooperation in nuclear security.

Good sense demands that policy makers not discount the possibility that ISIS might pursue unconventional weapons, given the vast resources of money and weapons ISIS has amassed during its rampage across Syria and Iraq.

Secretary of Defense Chuck Hagel recently described the Islamic State (IS, referred to by the U.S. government as the Islamic State of Iraq and the Levant [ISIL] and by many others as the  Islamic State of Iraq and Syria or the Islamic State of Iraq and al Sham [ISIS]) as an “imminent threat to every interest we have,” with sophistication, funding, and military prowess “beyond anything that we’ve seen.” As yet, there is no convincing publicly available evidence that IS aspires to attain or use nuclear, chemical, or biological weapons (Matthew Bunn debunked alarmist press coverage over the group’s seizure of uranium from Mosul University). But good sense demands that policy makers not discount the possibility that ISIS might pursue unconventional weapons, given the vast resources of money and weapons ISIS has amassed during its rampage across Syria and Iraq. Evaluation of the threat might be divided into two categories: the inclination to pursue CBRN weapons, and the means to manufacture or capture them, and afterwards, to plan an attack using them.

The most significant achievement to emerge from the 2014 Nuclear Security Summit was a pledge by 35 countries to observe the terms of a joint agreement, known as Strengthening Nuclear Security Implementation. This document committed the signatories to incorporate the principles and guidelines of the International Atomic Energy Agency (IAEA) regarding nuclear security into their national laws, and to allow teams of international experts to periodically evaluate their security procedures. Promoted strongly by the chairs of all three nuclear summits—the United States, South Korea, and the Netherlands— the 2014 initiative is an important step towards creating a robust global security system designed to prevent nuclear materials from falling into the hands of terrorists.

With the 2014 Nuclear Security Summit (NSS) now over, policymakers are thinking about next steps to address nuclear security. The NSS process has progressed since its first installment in 2010; yet, the Middle East, a key region where nuclear security is of tremendous importance, remains underrepresented.

Today, the United States and Japan announced that Japan would eliminate all the plutonium and highly-enriched uranium at its Fast Critical Assembly (FCA) at Tokai-mura.  This is a tremendous step forward for nuclear security; for terrorists, this would be some of the best material that exists in any non-nuclear-weapon state.  The material includes 331 kilograms of plutonium, most of it weapons-grade, and 214.5 kilograms of weapons-grade HEU.  (The FCA also includes over a ton of material just at the 20 percent U-235 mark that defines HEU.)   The weapons-grade HEU is enough for four simple terrorist “gun-type” bombs or a larger number of trickier-to-build implosion bombs.  The plutonium amounts to more than 40 bombs worth of material.
