Nuclear Issues

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

With the fourth and final nuclear security summit approaching in March, the 2016 edition of the Nuclear Threat Initiative (NTI) Nuclear Security Index raises red flags about the international community’s implementation of the important measures needed to protect against catastrophic nuclear terrorism and to build an effective global nuclear security system. More importantly, it raises the question, how will leaders sustain momentum and high-level political attention on the need to secure dangerous nuclear materials once the summits come to an end?

Are nuclear sites secure?  There are some who might assume the answer is yes and that we should not worry about the possibility of nuclear bomb material being stolen. Yet, recent history has repeatedly demonstrated that high security facilities thought to be secure were actually vulnerable. Two such incidents last month illustrated this idea.

In thinking about how nuclear security and safeguards can fail, it is useful to keep in mind why security usually fails in general.  Most security managers and organizations have a good understanding of the assets they are trying to protect, the resources available to them to protect those assets, and the consequences should security fail (though this is sometimes greatly underestimated).  They often have a reasonably accurate understanding of the threats they face—who might attack, why, how, when, and with what goals and resources.  What is often lacking is a good understanding of the vulnerabilities—the weaknesses in the security that can be exploited by the threats—and how those vulnerabilities can be mitigated or eliminated.

One of the more notable storylines throughout 2014 was the continued failures of the U.S. Secret Service. There were three striking high profile lapses in the Secret Service’s ability to protect President Obama: one where a man jumped over the White House fence, running through the front door of the White House and throughout its main floor; another where an armed man with an arrest record was able to ride on the same elevator as the President; and another where a man posing as a Member of Congress was able  to sneak into a secured area where the President was speaking. Towards the end of the year, problems within the Secret Service became a hotly debated political football, resulting in the resignation of the Service’s director.

Recently, the Senate Homeland Security and Governmental Affairs Committee held a hearing that highlighted some truly alarming information about the status of radiological security in the United States.  The hearing began with a description from Senator Carper (D-DE) of the Boston marathon bomb attacks. He then speculated on the hypothetical consequences of the use of a Radiological Dispersion Device (RDD) or “dirty bomb” (interestingly, an old high-activity Cs-137 source was removed from Massachusetts General Hospital after the bombing).

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.

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.
