The second Nuclear Security Summit (NSS) is being held 26-27 March in the capital of South Korea, Seoul.

The summit sees a gathering of 53 countries and international Organisations to evaluate achievements and reinforce implementation of the Work Plan of the first Nuclear Security Summit held in Washington, 2010.

This summit seeks to measure progress in efforts to strengthen global nuclear security. It will also provide the opportunity to explore possible additional priorities such as the security of radioactive sources and information security related to nuclear activities, relevant to the overall objective of achieving the highest level of nuclear security.

The NSS will review in particular the progress made in securing all vulnerable nuclear materials within four years.

The EU is represented at the meeting by Herman Van Rompuy, President of the European Council and José Manuel Barroso, President of the European Commission.
