Nuclear Issues

In this Project on Managing the Atom Discussion Paper, Philipp C. Bleek chronicles nuclear weapons proliferation choices throughout the nuclear age. Since the late 1930s and early 1940s, some thirty-one countries are known to have at least explored the possibility of establishing a nuclear weapons program. Seventeen of those countries launched weapons programs, and ten acquired deliverable nuclear weapons.

"One category of nuclear material that has not yet been adequately addressed throughout recent Nuclear Security Summits is military stockpiles.2 Instead, the Summit process has focused primarily on reducing the risk of civilian nuclear material theft..."

The abstracts in this booklet summarise the research presented at an academic symposium convened on the sidelines of the 2015 NPT Review Conference. As we write this, journalists and seasoned experts in the nuclear policy field have been speculating about the particularly difficult challenges facing the Review Conference this year. To address those challenges, we would urge all concerned to consider the ideas and analyses presented at this symposium. Experts would be hard-pressed to find a better collection of fresh ideas and approaches for assessing and strengthening the NPT.

Part of NTI's Innovating Verification reports series, Verifying Baseline Declarations of Nuclear Warheads and Materials analyzes how baseline declarations can contribute to near- and long-term arms control and non-proliferation goals and how to verify them without compromising sensitive information.

In the lead-up to the nuclear security summit, Advancing Nuclear Security: Evaluating Progress and Setting New Goals outlines what was accomplished in a four-year effort launched in 2009 to secure nuclear material around the globe—and what remains to be done. The effort made significant progress, but some weapons-usable nuclear materials still remain “dangerously vulnerable." The authors highlight the continuing danger of nuclear and radiological terrorism and call for urgent action.

In the 1970s, nuclear-power boosters expected that by now nuclear power would produce perhaps 80 to 90 percent of all electrical energy globally. Today, the official high-growth projection of the Organization for Economic Co‑operation and Developments (OECD) Nuclear Energy Agency (NEA) estimates that nuclear power plants will generate about 20 percent of all electrical energy in 2050. Thus, nuclear power could make a significant contribution to the global electricity supply. Or it could be phased out — especially if there is another accidental or a terrorist-caused Chernobyl-scale release of radioactivity. If the spread of nuclear energy cannot be decoupled from the spread of nuclear weapons, it should be phased out.

Recent foiled and successful terrorist plots in Europe and the US (including two cases in the UK and Germany which included plans to design radiological dispersal devices in 2004 and 2005), clearly demonstrate that domestic or locally acting terrorist cells have become an important part of the terrorist threat picture. The uncovered “dirty bomb” – plots involved radioactive material of type or quantity that would not have caused much damage. Still, these observations underscore the necessity to revisit the issue of radioactive sources security in countries which may become the target of a radiological attack. This includes in particular countries in Europe, many of which in the past relied on sophisticated — but safety centred — regulations and functioning oversight institutions.

Urgent actions are needed to prevent a nuclear or radiological 9/11.  Terrorists are actively seeking nuclear weapons and Radiological Dispersal Devices (RDDs) and the materials to make them.  There are scores of sites where the essential ingredients of nuclear weapons exist, in dozens of countries worldwide.  There are thousands of sites worldwide where radiological materials exist.  Many of these sites are not sufficiently secured to defeat the kinds of threats that terrorists and criminals have demonstrated they can pose.  A dangerous gap remains between the urgency of the threat of nuclear and radiological terrorism and the scope and pace of the U.S. and world response.  While the gap has narrowed significantly in recent years, much more needs to be done.  This paper describes the nuclear and radiological terrorism threats, analyzes the actions taken so far to address these threats, and recommends further actions going forward.

Leaders at the 2010 nuclear security summit agreed on the goal of securing all vulnerable nuclear material in four years, but the factors that drive and/or constrain nuclear security changes are not well understood. Matthew Bunn and Eben Harrell surveyed nuclear security professionals in countries with nuclear weapons, HEU, or separated plutonium to explore this issue. This paper describes the survey, its results, and implications for strengthening global nuclear security.
