Abstract:
Leaders at the 2010 nuclear security summit agreed on the goal of securing all vulnerable nuclear material in four years. This goal implied that many countries would change their nuclear security policies. But the factors that drive changes in nuclear security policies, and that constrain those changes, are not well understood. Matthew Bunn and Eben Harrell conducted a survey of selected nuclear security experts in countries with nuclear weapons, highly enriched uranium (HEU), or separated plutonium, to explore this issue. The survey included: perceptions of which threats are credible; approaches to nuclear security based on a design basis threat (DBT); changes in nuclear security policy in the last 15 years; factors causing and constraining changes in nuclear security policy; and policy on how much information to release about nuclear security. This paper describes the survey, its results, and implications for next steps to strengthen global nuclear security.

2. A Worst Practices Guide to Insider Threats: Lessons from Past Mistakes

Abstract:
Insider threats are perhaps the most serious challenges that nuclear security systems face. All of the cases of theft of nuclear materials where the circumstances of the theft are known were perpetrated either by insiders or with the help of insiders; given that the other cases involve bulk material stolen covertly without anyone being aware the material was missing, there is every reason to believe that they were perpetrated by insiders as well. Similarly, disgruntled workers from inside nuclear facilities have perpetrated many of the known incidents of nuclear sabotage. The most recent example of which we are aware is the apparent insider sabotage of a diesel generator at the San Onofre nuclear plant in the United States in 2012; the most spectacular was an incident three decades ago in which an insider placed explosives directly on the steel pressure vessel head of a nuclear reactor and then detonated them. While many such incidents, including the two just mentioned, appear to have been intended to send a message to management, not to spread radioactivity, they highlight the immense dangers that could arise from insiders with more malevolent intent. As it turns out, insiders perpetrate a large fraction of thefts from heavily guarded non-nuclear facilities as well. Yet organizations often find it difficult to under - stand and protect against insider threats. Why is this the case?

3. Preventing Nuclear Terrorism: A Progress Update

Abstract:
In the past year, there has been notable progress in ensuring that stockpiles of the essential ingredients of nuclear weapons around the world are secured from theft and transfer to terrorists. But there remains a dangerous gap between the pace of progress and the scope and urgency of the threat – a gap that, if left unfilled, could lead to unparalleled catastrophe. We must close the gap – to take action now that, within a few years, could reduce the danger that terrorists might turn the heart of a U.S. city into a new Hiroshima to a fraction of what it is today. This paper is intended to outline the continuing threat; summarize the progress made in addressing it in the past year, and the gaps that still remain; and recommend steps to close the gap between threat and response. The terrorists who have sworn to kill Americans wherever they can be found have undertaken an intensive effort to get a nuclear bomb, or the materials and expertise needed to make one. We need to be racing as fast as we can to stop them before they succeed. This paper is about steps to win that race.

4. The Next Wave: Urgently Needed New Steps to Control Warheads and Fissile Material

Abstract:
Nothing could be more central to U.S. and world security than ensuring that nuclear warheads and their essential ingredients—plutonium and highly enriched uranium (HEU)—do not fall into the hands of terrorists or proliferating states. If plutonium and HEU become regularly available on a nuclear black market, nothing else we do to prevent the proliferation of nuclear weapons will succeed. Similarly, unless stockpiles of nuclear warheads and fissile materials can be secured, monitored, and verifiably reduced, it will be impossible to achieve deep, transparent, and irreversible reductions in nuclear arms. Measures to control warheads and fissile materials, therefore, are central to the entire global effort to reduce nuclear arms and stem their spread. The tens of thousands of nuclear weapons and hundreds of tons of plutonium and HEU that remain in the U.S. and Russian nuclear stockpiles represent a deadly legacy of the Cold War, and managing them securely must be a top U.S. security policy priority.
