Nuclear Issues

Nuclear security around the world has improved dramatically over the last three decades—which demonstrates that with focused leadership, major progress is possible. But important weaknesses remain, and the evolution of the threat remains unpredictable. The danger that terrorists could get and use a nuclear bomb, or sabotage a major nuclear facility, or spread dangerous radioactive material in a “dirty bomb,” remains too high. The United States and countries around the world need to join together and provide the leadership and resources needed to put global nuclear security on a sustained path of continuous improvement, in the never-ending search for excellence in performance.

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.

In this new report, Preventing Nuclear Terrorism: Continuous Improvement or Dangerous Decline?, Matthew Bunn, Martin Malin, Nickolas Roth, and William Tobey provide a global reality check on nuclear security. They note that effective and sustainable nuclear security capable of addressing plausible threats is the single most effective chokepoint preventing terrorists from acquiring a nuclear weapon.

"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.

In 1996, the International Atomic Energy Agency (IAEA), the United States and the Russian Federation entered into a cooperative effort – the Trilateral Initiative – aimed at investigating the feasibility and requirements for a verification system under which the IAEA could accept and monitor nuclear warheads or nuclear warhead components pursuant to the NPT Article VI commitments of both States. Although the Initiative ended in 2002, the Model Verification Agreement produced could still serve as the basis for bilateral or multilateral agreements between the IAEA and nuclear-weapon States.

In this paper, Thomas E. Shea and Laura Rockwood examine the potential role for international verification of fissile material in relation to nuclear disarmament, what was accomplished under the Trilateral Initiative and, more importantly, what should be done now to preserve its legacy and take concrete steps towards such verification.

Characterizing the future performance of energy technologies can improve the development of energy policies that have net benefits under a broad set of future conditions. In particular, decisions about public investments in research, development, and demonstration (RD&D) that promote technological change can benefit from (1) an explicit consideration of the uncertainty inherent in the innovation process and (2) a systematic evaluation of the tradeoffs in investment allocations across different technologies. To shed light on these questions, over the past five years several groups in the United States and Europe have conducted expert elicitations and modeled the resulting societal benefits. In this paper, the authors discuss the lessons learned from the design and implementation of these initiatives.

"Since the 9/11 attacks, China has made significant progress on its nuclear security system, with a focus on switching from the traditional “guns, gates, guards” approach to an effective mixed approach that combines well-trained personnel with up-to-date techniques and technology. The major advancements include a security approach based on a design basis threat (DBT); application of modern concepts of physical protection, based on systems-engineering approaches to analyzing vulnerabilities and designing defenses to address them; the use of modern physical protection, material control, and material accounting technologies; requirements for in-depth vulnerability assessments of security systems; and improvements to the organization of nuclear security and guard force training and equipment on the part of facility operators..."

The Obama administration has proposed steep cuts in funding for improving security for dangerous nuclear materials. If approved, they would slow progress toward preventing the essential ingredients of nuclear bombs from falling into terrorist hands. Cutting too Deep reviews funding trends over the past four years and describes how the proposed cuts would delay nuclear and radiological material removal, research reactor conversion, and other work.
