As an institutional embodiment of the international safeguards regime, the IAEA has been central to the international diplomacy of nuclear control and efforts to limit nuclear-weapons proliferation. It has played an important role as a negotiator, facilitator and an implementation agency; it has been the core of the regime in its capacity as the role of nuclear watch-dog. This book traces the evolution of the International Atomic Energy Agency (IAEA) as an autonomous and an effective mechanism in facilitating international cooperation in the peaceful uses of nuclear technology, application of safeguards and the maintenance of safety standards of the nuclear installations. The study explores the importance of IAEA’s role is in the nuclear technology cooperation for peaceful uses and verifications. It also seeks to identify the special features in structure, decision-making processes and work-culture within IAEA. The work should generate sufficient interest among the scholars of International Organization, International politics & Multilateral Arms Control Verification regimes, as also, anyone else who is keen to understand the functional dynamics of International Organizations.
