The summit will be attended by over 50 world leaders, thousands of delegates and some 3,000 journalists. The heads of four international organisations (UN, IAEA, EU (2x) and Interpol) will attend the summit.
The Nuclear Security Summit aims to prevent nuclear terrorism by reducing the amount of dangerous nuclear material in the world; improving the security of all nuclear material and radioactive sources; improving international cooperation.
The first NSS was held in Washington D.C. in 2010, followed by a second summit in Seoul in March 2012.
Since the Washington summit in 2010, agreements have been made to better secure hazardous nuclear material (highly enriched uranium and plutonium).
At the 2012 summit, the participants discussed the progress made and added the security of radioactive sources used for ‘dirty bombs’ to the agenda.
