The IAEA Global Nuclear Safety and Security Network (GNSSN) is a human network operating at global, regional and national levels, supported by a strong web platform. GNSSN is a key support element of the Global Nuclear Safety and Security Framework (GNSSF) defined here as “the institutional, legal and technical framework for ensuring the safety of nuclear installations throughout the world. The objective of this [framework] is to lead to a world where all nuclear installations are operating safely” (Strengthening the Global Nuclear Safety Regime, INSAG Series No. 21).
