The nuclear security summit initiative was announced in an April 2009 speech by U.S. President Barack Obama, in which he pledged to hold a global summit on nuclear security in 2010 as part of an effort to "secure all vulnerable nuclear material around the world within four years.” The broad goal of the summit process is to address the threat of nuclear terrorism by minimizing and securing weapons-usable civilian nuclear materials, enhancing international cooperation to prevent the illicit acquisition of nuclear material by non-state actors such as terrorist groups and smugglers, and taking steps to strengthen the global nuclear security system. The nuclear security summit focus remained on nuclear material in the civil sphere and did not address the security of military nuclear material.

There were four summits in total: in Washington, D.C. in 2010, Seoul, South Korea in 2012, the Hague, Netherlands in 2014 and Washington, D.C. again in 2016.

Each summit produced a consensus communiqué that reaffirmed the broad goals of the summit process and encouraged states to take actions, such as ratifying key treaties or minimizing stockpiles of weapons-usable materials. These voluntary, caveated recommendations were enhanced by individual state-specific commitments made at each summit. These pledges, known as “house gifts,” included actions such as repatriating weapons-usable materials, holding trainings for nuclear security personnel, updating national laws and regulations, and taking steps to combat illicit trafficking. At each subsequent summit, states reported on the progress made toward fulfilling these commitments. All 53 participating states made national pledges at at least one summit.

Beginning at the 2012 summit in Seoul, groups of countries offered multinational commitments, known as “gift baskets” that targeted key areas of nuclear security. In 2012, 13 joint statements were offered. That number increased to 14 in 2014, with some gift baskets building off of 2012 statements and others targeting new areas. In 2016, states produced 21 gift baskets.

Of the 53 countries to participate in the 2012 summit, 48 participated in at least one joint statement in 2012.

At the last summit in 2016, countries agreed to five action plans for international organizations to take forward the work of the summits beyond their conclusion.

Washington 2010

The first Nuclear Security Summit was held in Washington, D.C. from April 12-13, 2010. Forty-seven national delegations as well as the heads of the United Nations, the International Atomic Energy Agency (IAEA) and the European Union attended. With 38 of the 47 participating countries represented at the head of state or head of government level, the gathering was the largest of its kind hosted by a U.S. President since 1945.

The summit produced the first of four communiqués, the summit’s only work plan, and the first national commitments or house gifts.


  • Recognizes that highly enriched uranium (HEU) and separated plutonium require special precautions and encourages the conversion of reactors from HEU to low enriched uranium (LEU) fuel and minimization of use of HEU, where feasible.
  • Reaffirms the essential role of the International Atomic Energy Agency in the international nuclear security framework and will work to ensure that it continues to have the appropriate structure, resources and expertise to carry out its activities.
  • Recognizes the continuing role of nuclear industry in nuclear security.
  • Supports the implementation of strong nuclear security practices that will not infringe upon the rights of States to develop and utilize nuclear energy for peaceful purposes and technology and will facilitate international cooperation in the field of nuclear security.

Washington Work Plan 

The Work Plan lays out the specific steps for realizing the goals of the Communiqué, including ratification and implementation of international treaties; support for Security Council Resolution 1540; conversion of civilian facilities from HEU to non-weapons-useable materials; research on new nuclear fuels; detection methods and forensic technologies; development of corporate and institutional cultures that prioritize nuclear security; education and training; and joint exercises among law enforcement and customs officials to enhance nuclear detection opportunities.

Selected National Commitments (House Gifts)

Thirty countries announced 67 specific measures they planned to implement to support the goals of the summit. Prior to the 2012 Seoul summit, approximately 80 percent of these commitments were completed. For an accounting of the implementation of the 2010 national commitments, see: The Nuclear Security Summit: Assessment of National Commitments, March 2012.

Some of the national commitments include:

  1. Belgium, Kazakhstan, Mexico, New Zealand, Norway and the United Kingdom will convert a HEU research reactor to LEU.
  2. Canada will return a large amount of spent HEU fuel from their medical isotope production reactor to the United States and fund HEU removals from Mexico and Vietnam.
  3. Kazakhstan, Mexico and Ukraine will eliminate remaining HEU. Ukraine committed to eliminate half of its HEU by the year’s end.
  4. Norway will contribute $3.3 million over the next four years to the IAEA nuclear security fund.
  5. Russia committed to sign the Plutonium Disposition protocol to  end plutonium production and to contribute to IAEA’s Nuclear Security Fund.

  Seoul 2012

From March 26-27, 2012, 53 heads of state along with representatives from the UN, IAEA, EU and INTERPOL gathered for the second nuclear security summit in Seoul, South Korea. Participating countries included the 47 countries that attended the 2010 Nuclear Security Summit plus Azerbaijan, Denmark, Gabon, Hungary, Lithuania, and Romania.

The scope of the 2012 agenda was expanded to include discussions on the security of radiological sources and the interface between nuclear security and safety, a concern highlighted by the March 2011 nuclear disaster in Fukushima, Japan.

In additional to the consensus communiqué and national commitments, or house gifts, states also introduced joint proposals, or gift baskets for the first time in 2012. All states also submitted voluntary progress reports on their national commitments from 2010.

Such measures include exchanging good practices, inviting IAEA review and advisory services and following through on recommendations, further developing training of personnel involved in nuclear security.
  • Supports a more intensive dialogue between operators and government bodies, including the national regulator, which should be functionally independent, with a view to improving nuclear security regulations and regulatory effectiveness.
  • Encourages states to take effective risk mitigation measures to ensure that the systems and networks of nuclear facilities are appropriately secured from cyber attack.
