The IAEA, the world’s hub of cooperation in the nuclear field, is the nucleus around which all other parts of the global nuclear governance system revolve, promoting safe, secure and peaceful nuclear technologies. All aspects of the Agency’s mandate and operations ― from its major programs on safeguards, safety, security and the peaceful uses of nuclear energy to governance, management and finance ― are examined in this 160-page report. Unleashing the Nuclear Watchdog confirms that the IAEA requires strengthening and reform in certain areas, but does not need a dramatic overhaul.
