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.

At a meeting 23 and 24 March in Belgrade, US and Russian members of the Elbe Group – retired general officers from the military and intelligence services – declared that the risk of terrorism, both conventional and nuclear, is growing.  They urged that special attention must be given to preventing Daesh, al Qaeda, and other terrorist organizations which have declared openly their desire to gain weapons of mass destruction, from obtaining them.

Matthew Bunn, William Tobey, and I have a new op-ed in The Hill’s Congress Blog, “Don’t weaken our defenses against nuclear smuggling.” We wrote it in response to proposed legislation that would prohibit funding for fixed radiation detectors to catch nuclear smugglers – both for installing new ones and even for maintaining the ones U.S. taxpayers have already paid billions to install.

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.

NRC Chair announces she is stepping down, "notable progress" in security at Y-12, unmanned drones over French nuclear plants, and more.

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.

This week’s Nuclear Security Summit in The Hague was understandably overshadowed by the continuing international response to Russia’s illegal annexation of Crimea. One aspect of the Ukraine crisis that deserves more attention is how the current standoff will impact the future of nuclear security cooperation between the United States and Russia.

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.
