International Nuclear Security Forum
A network of civil society organizations dedicated to reducing nuclear terrorism risks

We are at a critical crossroads for preventing nuclear terrorism. After years of progress strengthening nuclear security, momentum is slowing. Ensuring strong security at nuclear facilities is a global challenge, requiring leadership and cooperation from policymakers, international institutions, operators, and civil society.

To meet this challenge, the International Nuclear Security Forum provides a space for a diverse group of international experts to identify, create, and support strategies for reducing nuclear terrorism risks.

  • Creating opportunities for collaboration and dissemination of members’ products/expertise
  • Educating stakeholders on a range of perspectives for achieving nuclear security policy goals​
  • Supporting international nuclear security implementation and architecture
  • Promoting nuclear security information sharing
  • Fostering international nuclear security leadership

By working with the nuclear security community to build stronger bridges between international experts, the INSF will provide timely information to members, and focus on strengthening stakeholder knowledge and capacity. 

More: Read the INSF Statement of Principles

An act of nuclear terrorism anywhere in the world would be a global humanitarian, economic, and political catastrophe and would undermine the role of nuclear technology for energy, medical, industrial, and other purposes. The most effective strategy for preventing nuclear terrorism is to ensure strong and sustainable security for all nuclear and radiological materials and nuclear facilities, whether associated with energy, research, weapons, or any other purpose. To support this goal the International Nuclear Security Forum seeks to build stronger bridges among international nuclear security experts, provide timely information to members, and focus on strengthening stakeholder knowledge and capacity. In doing so, International Nuclear Security Forum members,

Recognize the successes of previous multilateral, national, and civil society initiatives to strengthen nuclear security;

Affirm that despite these successes, progress on nuclear security has slowed, and therefore strengthening nuclear security must remain an important international priority for global security, and that progress toward that end can be facilitated by international and interdisciplinary cooperation;

Determine to serve as a hub for strengthening expertise and sharing experience for Forum members;

Welcome diversity in perspective, experience, and thought to address increasingly interconnected global nuclear terrorist and other threats, and identifying opportunities for strengthening security; and

Support strengthening the global nuclear security architecture, sharing non-sensitive nuclear security information to build global confidence, implementing measurable nuclear security best practices and standards, and creating sustainable multilateral mechanisms that support continuous nuclear security progress.

Recognizing the urgency and necessity of sustaining and growing the nuclear security community, the International Nuclear Security Forum supports efforts that will:

  1. Elevate expert and political attention to the challenges of preventing nuclear and radiological terrorism, and the contributions of nuclear security to the sustainability of peaceful uses of nuclear technology.
  2. Foster innovative and creative approaches to problem solving and analysis to reinvigorate international attention and support for stronger nuclear security.
  3. Enhance equity and inclusion in the community by actively incorporating diversity of perspectives in order to improve the quality and credibility of our nuclear security policy initiatives.
  4. Cultivate the next generation nuclear security community through active educational outreach and mentorship.
  5. Encourage leadership by engaging policymakers, international institutions, operators, and civil society in constructive dialogue on nuclear security-related threats and opportunities to address the danger.

 As members of the International Nuclear Security Forum, we endorse the preceding principles and values that will help to foster a “whole-of-community” approach to strengthening nuclear security world-wide.

Achievements

The International Nuclear Security Forum builds upon the incredible work of the Fissile Material Working Group (FMWG), which was the preeminent civil society coalition supporting policies to reduce the risk of nuclear terrorism. Central to its successes was the FMWG’s engagement with a broad array of international stakeholders.

Nuclear Summits & Symposia

The FMWG organized the convening of a summit of international experts and events in support of the official 2010 Nuclear Security Summit (NSS). Additionally, the FMWG provided assistance to South Korean planners organizing the 2012 Nuclear Security Symposium experts event and to Dutch planners organizing the 2014 Nuclear Knowledge Summit. The FMWG also organized the fourth civil society summit, Solutions for a Secure Nuclear Future, to support the 2016 NSS.

Working Groups

The creation of three Policy Development Working Groups by the FMWG led to recommendations on: (1) the elimination of civilian highly-enriched uranium (HEU), (2) addressing military nuclear materials, and (3) information-sharing, standards and best practices, and security culture. The FMWG published a joint recommendations report that summarized the key policy proposals from all three groups: The Results We Need: Policy Recommendations for the 2016 Nuclear Security Summit.

Policy Recommendations

The FMWG published its consensus recommendations for the Obama administration on improving nuclear material security (September 2009), updated recommendations to world leaders before the 2012 Nuclear Security Summit (January 2012), and a new list of 8 recommendations (October 2013) that includes a plutonium policy recommendation agreed to in March 2013.
