Sixty years ago, on 23 October 1956, an international conference at the United Nations (UN) headquarters in New York adopted the Statute of the International Atomic Energy Agency (IAEA). The document is almost as long as the UN Charter and remains the legal foundation of ‘the Agency,’ as the world nuclear organization is widely called.^[1] This H-Diplo/ISSF policy roundtable uses the anniversary as an opportunity to discuss the IAEA’s mandate and role in history and current affairs. Does the IAEA Statute, which was written in a very different context, stand up to scrutiny today? What does the answer suggest about the IAEA and institutions of global nuclear governance more generally? How can the IAEA be strengthened?

This report proposes a framework for IAEA verification of steps toward nuclear disarmament, premised on IAEA verification of fissile material, in any form, whether classified or not, submitted by any state possessing nuclear weapons. It identifies technical, legal, and financial solutions to the challenges posed by such verification, and offers a way forward to the implementation of the proposed framework. The tool that Rockwood and Shea offer is ready for any state with nuclear weapons to take up, finish the final details, and implement.

In 1996, the International Atomic Energy Agency (IAEA), the United States and the Russian Federation entered into a cooperative effort – the Trilateral Initiative – aimed at investigating the feasibility and requirements for a verification system under which the IAEA could accept and monitor nuclear warheads or nuclear warhead components pursuant to the NPT Article VI commitments of both States. Although the Initiative ended in 2002, the Model Verification Agreement produced could still serve as the basis for bilateral or multilateral agreements between the IAEA and nuclear-weapon States.

In this paper, Thomas E. Shea and Laura Rockwood examine the potential role for international verification of fissile material in relation to nuclear disarmament, what was accomplished under the Trilateral Initiative and, more importantly, what should be done now to preserve its legacy and take concrete steps towards such verification.

"In September 2013, the International Atomic Energy Agency (IAEA) Board of Governors reviewed a report by Director-General Yukiya Amano on efforts to further strengthen the effectiveness of safeguards and increase their efficiency. The report described an approach to the implementation of safeguards that had come to be known as the “state-level concept.”
