In this second webinar of the Southeast Asia Nuclear Dialogue Series, John Haddad, Representative for Nuclear Infrastructure Development at the IAEA, will present on how newcomer countries can develop the necessary infrastructure to consider nuclear energy. Drawing from his experience in national planning and his current role in the IAEA's Nuclear Infrastructure Development Section (NIDS), John will introduce the IAEA’s milestone approach, a structured framework guiding countries from early energy planning through to nuclear readiness. The presentation will explain what infrastructure is needed, the roles and responsibilities of different national actors, the importance of continuous government support, and how the IAEA can assist throughout the process, including technical, legal, regulatory, and safeguards support. Specific country examples will help illustrate real-world applications.
