Nuclear Issues

“An RDD [Radiological Dispersion Device] detonated in a major metropolitan area could result in economic costs in the billions of dollars as a result of evacuations, relocations, cleanup, and lost wages. Radioactive sources such as Cobalt, Cesium, Americium, and Iridium are used worldwide for many legitimate purposes and are located at thousands of sites in the United States and around the world.

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.

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.

Since the 2010 Nuclear Security Summit, Centers of Excellence have been recognized as an important part of the global nuclear security architecture. Centers of Excellence serve as a mechanism for ensuring individuals, whether facility managers, regulatory staff, scientists, engineers, or technicians, are trained on a wide number of important nuclear security issues. These centers focus on the important “human factor” of the global effort to secure nuclear material.

In August of 2002, the United States – assisted by a gift from the Nuclear Threat Initiative, when it turned out no U.S. agency had money that was not blocked from doing what was needed – helped airlift 48 kilograms of 80% enriched highly enriched uranium out of the Vinca nuclear research institute in Serbia.  A force of 1,200 armed troops guarded the shipment as it moved from the lab to the airport.  Under international rules, this was dangerous “Category I” material requiring the highest level of security. But under Department of Energy (DOE) rules for categorizing nuclear material, if the same material had been at a DOE site, it would have been considered “Category III” material requiring hardly any security.

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.

In what one Dutch official called the “most important deliverable from the Summit,” thirty-five nations, led by the host governments of the Nuclear Security Summits in Washington, Seoul, and The Hague, announced today their commitment to strengthen nuclear security implementation.

In September 2009, a group of masked men armed with automatic weapons and explosives arrived on the roof of a cash depot in Vastberg, Sweden in a helicopter. The men blasted their way through a skylight and hoisted millions of dollars up to the hovering aircraft — the operation took less than 20 minutes. When police rushed to respond they discovered a bag with the word “bomb” at their heliport — a diversion planted by the thieves — and caltrops (road spikes) near the depot to slow down their response on the ground. While many of the thieves were caught after an investigation, most of the money was never recovered.

In the spectrum of threats to nuclear security, highly radioactive materials such as cesium-137 and cobalt-60 represent a set of concerns and challenges which is much different from that of fissile materials like highly enriched uranium. Unlike the latter, they cannot be used to build a nuclear weapon. However, terrorists could use such sources to construct a so-called “dirty bomb”, an improvised explosive device which spreads the radioactive substances in a populated area. Although, according to most planning scenarios, such a “dirty bomb” would likely cause few radiation-related casualties, its economic effects could still be in the billions of dollars – especially if parts of a city needed to be shut down for weeks or months while they are being decontaminated.
