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.

On 24 and 25 November 2016 experts from politics and academia, including FDP Executive director Cathryn Clüver, discussed the impact of Brexit on several policy areas in a series of workshops at the Hertie School of Governance in Berlin. All events took place under Chatham House rules.

Reducing the Use of Highly Enriched Uranium in Civilian Research Reactors is a report of the Committee on the Current Status of and Progress Toward Eliminating Highly Enriched Uranium Use in Fuel for Civilian Research and Test Reactors. The committee was established by the Nuclear and Radiation Studies Board, Division on Earth and Life Studies and the National Academies of Sciences, Engineering, and Medicine. The report is the result of a congressionally mandated study (P.L. 112-239, Section 31781) to assess improvement in reducing highly enriched uranium use in fuel for civilian research and test reactors.

Belfer Center Senior Fellow William Tobey is a member of the Committee that produced the report.

"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 trying to prevent adversaries from acquiring new military capabilities, countries often employ strategies of arms denial; e.g., “unilateral diplomacy,” supply chain interdiction, covert sabotage, and targeted military strikes. Using a game-theoretical model of weapons acquisition and denial, the authors posit that the prevalence of this approach gives rise to strategic effects that affect all players’ behavior.

The last seven decades without war among the great powers – what historians describe as “the long peace” – is a remarkable achievement. “This is a rare and unusual fact if you look at the last few thousand years of history,” said Graham Allison, director of the Belfer Center and moderator of the IDEASpHERE panel “Winning the Peace.” “Furthermore, it is no accident. Wise choices by statesmen have contributed to ‘the long peace,’ which has allowed many generations to live their lives.”

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.

The 2011 “U.S. - Russia Joint Threat Assessment” offered both specific conclusions about the nature of the threat and general observations about how it might be addressed. This report builds on that foundation and analyzes the existing framework for action, cites gaps and deficiencies, and makes specific recommendations for improvement.
