Reports & Papers

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.

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.

A long-standing goal of diplomacy with Iran is persuading Iran to suspend its enrichment operations while it clarifies its past activities and while negotiations proceed on a more permanent resolution to the nuclear crisis. However, there is problem in using suspension of nuclear material production as a negotiating step: The technical details of suspension have never been clearly defined. The international community needs to be aware of the diversion risks during a suspension of enrichment activities and should mitigate these risks by including the necessary verification measures during negotiations and signing of any agreement on suspension.

Illicit trade from the international marketplace plays a direct role in sustaining the nuclear and missile programs of several countries, including Iran, in defiance of UN sanctions. This paper sets out what measures the private sector should take in order to manage the legal, financial and reputational risks associated with involvement in proliferation-related trade, and makes recommendations to national authorities for how for how to help the private sector identify and prevent potential proliferation.

Nearly all of the 190 signatories to the Nuclear Non-Proliferation Treaty (NPT) agree that the forty-two-year-old treaty is fragile and in need of fundamental reform. But gaining consensus on how to fix the NPT will require reconciling the sharply differing views of nuclear weapon states and non-nuclear weapon states. Strengthening the international rules is increasingly important as dozens of countries, including some with unstable political environments, explore nuclear energy. The result is an ever-increasing distribution of this technology. In this paper, Steven E. Miller outlines the main points of contention within the NPT regime and identifies the issues that have made reform so difficult.

Matthew Kroenig examines the effect of the spread of nuclear weapons on international politics in a Managing the Atom Working Paper.  He observes that the spread of nuclear weapons threatens some states more than others, and proposes a theory of nuclear proliferation that examines the differential effects of proliferation.  He argues that the threat nuclear proliferation poses to a particular state depends on that state’s ability to project military power.  The spread of nuclear weapons is worse for states that have the ability to project conventional military power over a potential nuclear weapon state because nuclear proliferation constrains their conventional military freedom of action.

When do states attack or consider attacking nuclear infrastructure in nonnuclear weapons states? Despite the importance of this question, relatively few scholarly articles have attempted to identify the factors that lead a state to attack another state's nuclear facilities. This paper conducts the first large-n analysis on when states use force as a way to control proliferation.

This paper challenges existing arguments that states are deterred from attacking nuclear programs by the prospect of a military retaliation from the proliferating state or concerns about international condemnation. Instead, it finds that states are more likely to attack nuclear programs when they believe that the proliferating state might use nuclear weapons or engage in other offensive behavior. States are willing to accept substantial costs in attacking if they believe that a particular country's acquisition of nuclear weapons poses a significant threat to their security.

Hui Zhang presented his paper "Decommissioning the North Korean Nuclear Facilities: Approaches and Costs," at the Institute for Nuclear Materials Management 50th Annual Meeting, in Tucson, Arizona, 12-16 July 2009.

Andrew Newman and Matthew Bunn assess the Obama administration's fiscal year 2010 budget request for programs to improve controls over nuclear weapons, materials, and expertise worldwide. Funding for U.S. Efforts to Improve Controls Over Nuclear Weapons, Materials, and Expertise Overseas: A 2009 Update concludes that the request is a "steady as you go" budget and recommends that Congress and the administration work together to establish a $500 million contingency fund that could be used flexibly on a range of nuclear security programs.
