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.

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

As world leaders gather for the fourth nuclear security summit this week, in the aftermath of the horrifying terrorist attacks in Brussels, it seems likely that Belgian Prime Minister Charles Michel will have more to say than anyone else — both about real nuclear terrorist dangers and about real steps taken to improve nuclear security.

Ukraine-based journalist Maxim Tucker has just published two articles to claim that pro-Russian rebels in Eastern Ukraine are plotting to manufacture a dirty bomb with the help of Russian scientists, using radioactive waste from a storage facility at the Donetsk Chemical Factory.

Matthew Bunn, Will Tobey, Hui Zhang, and Nickolas Roth recently participated in a two-day roundtable discussion sponsored by the Stanley Foundation on U.S. nuclear security cooperation with Russia and China. The discussion, which involved experts from around the world, focused on overcoming challenges to nuclear security cooperation and ensuring that countries put in place effective and sustainable nuclear security measures with strong security culture.

Republicans and Democrats alike have traditionally understood that investing in nuclear security is a small price to pay compared with the devastating economic, political and social costs of nuclear terrorism. That’s why U.S. cooperation with Russia and other countries to secure vulnerable nuclear material has enjoyed bipartisan support.

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.

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.

Like dozens of other world leaders, Chinese President Xi Jinping is preparing to attend the third Nuclear Security Summit, which will take place in The Hague on March 24 and 25.  China actively participated in the first two summits, and since the 9/11 terrorist attacks in 2001, China has indeed made strides in strengthening its system for protecting nuclear facilities.  To make sure that nuclear security systems are actually implemented effectively, however, the development of a strong security culture—in which the relevant individuals hold a deeply rooted belief that insider and outsider threats are credible—is imperative.
