Nuclear Security Summit

Nuclear Security Summit is a physics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Nuclear Security Summit rather than just read about it. In short: The Nuclear Security Summit (NSS) was a semi-annual world summit, aimed at preventing nuclear terrorism around the globe. The first summit was held in Washington, D.C., United States, on April 12–13, 2010.

Key takeaways

  • Nuclear Security Summit belongs to physics; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Nuclear Security Summit to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Nuclear Security Summit from memory before moving on to harder problems.

Reference excerpt

The Nuclear Security Summit (NSS) was a semi-annual world summit, aimed at preventing nuclear terrorism around the globe. The first summit was held in Washington, D.C., United States, on April 12–13, 2010. The second summit was held in Seoul, South Korea, in 2012. The third summit was held in The Hague, Netherlands, on March 24–25, 2014. The fourth and final summit was held in Washington, D.C., on March 31–April 1, 2016.

History

Background In 2009, U.S. President Obama delivered a speech in Prague in which he called nuclear terrorism one of the greatest threats to international security. With that in mind, Obama hosted the first Nuclear Security Summit (NSS) in Washington, D.C., in 2010, in order to draw attention, at the highest possible level, to the need to secure nuclear material and thus prevent nuclear terrorism. Forty-seven countries and three international organisations participated in the first summit. In 2012 the second NSS was held in Seoul. Fifty-three countries and four international organisations were invited. The first summit was concerned with making political agreements, while the follow-up in Seoul focused on the progress made on implementing those agreements. The third NSS, in The Hague in 2014, centred on the results achieved and the future. Under the NSS process, countries worked to improve their nuclear security on the basis of the Washington Work Plan, which contained numerous measures and action points. In Seoul a number of additional action points were formulated and set down in the Seoul Communiqué. The NSS process was ongoing, and since 2009 has required world leaders and diplomats to devote extra attention to the issue of nuclear security. Extensive consultations were held in the run-up to every summit. For NSS 2014 this process started in 2012. The negotiators for the various countries, known as sherpas and sous sherpas, discussed the progress made and conferred on key themes, work plans and measures. Ultimately, these negotiations lead to decisions, which were later affirmed at the summit and published in a communiqué.

NSS 2010

Forty-seven countries and three international organizations participated in the first Nuclear Security Summit, held in Washington in 2010 at the initiative of President Obama. The aim of the summit was to improve worldwide nuclear security by enhancing cooperation and to make concrete agreements aimed at better securing nuclear materials and facilities. The results of the summit were set down in the Washington Work Plan in the form of concrete plans and action points, and the Washington Communiqué, which contains commitments and declarations of intent from the participating countries. The commitments made in Washington in 2010 are:

Leaders jointly affirmed the seriousness and urgency of the threat posed by nuclear terrorism. The participating countries agreed to work to secure all vulnerable nuclear material worldwide. The participating countries agreed to shoulder their responsibility for securing nuclear material within their own borders. The participating countries agreed to work together as an international community to improve nuclear security.

NSS 2012

Following the summit in Washington in 2010 six new countries (Azerbaijan, Denmark, Gabon, Hungary, Lithuania and Romania) and one new international organisation (Interpol) were invited by South Korea to join the NSS. Fifty-three countries attended the second summit in Seoul in 2012, which built on the goals that had been identified in Washington. New ambitions were added to the Washington Work Plan: the participants recognised the need to increase synergy between nuclear safety and security and better protect radiological sources from theft and misuse. Radiological sources may not be usable for a nuclear weapon, but they are well suited for making a ‘dirty bomb’, which can release radiation and cause social upheaval. The concrete results of the summit were presented in the Seoul Communiqué.

NSS 2014

The 2014 summit in March 2014 in The Hague, the Netherlands, charted the accomplishments of the past two years, identifying which of the objectives set out in the Washington Work Plan and the Seoul Communiqué have not been met and proposing ways to achieve them. The intention of the host country was to focus on the following achievable and visible goals:

Optimal security for and, if at all possible, a reduction in the use of highly enriched uranium and plutonium. Ratification of the amended Convention on the Physical Protection of Nuclear Material by more countries to ensure that the amendment enters into force as soon as possible. More frequent reviews of state security structures by IAEA advisory missions. National registration and protection of highly radioactive sources (e.g. medical equipment). Greater role for industry in nuclear security, to enhance the security culture and existing regulations. States should provide information to their own people and the international community to demonstrate that they are taking appropriate measures to maintain the security of their nuclear material and facilities. These confidence-building measures will increase trust in the international protection system.

Worked examples

Example 1 — a first encounter with Nuclear Security Summit

Start with the simplest possible case. Write down what Nuclear Security Summit claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Nuclear Security Summit before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Nuclear Security Summit ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Nuclear Security Summit

In research
Nuclear Security Summit appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Nuclear Security Summit in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Nuclear Security Summit is common in secondary-school and first-year university syllabi. It links to neighbouring topics 21st-century diplomatic conferences, Foreign relations of the United States, Nuclear weapons policy, so understanding it makes those chapters shorter.
In everyday life
Look for Nuclear Security Summit outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
