It would be expected that once a State makes a decision to proceed with the infrastructure development (i. e., Milestone 1 is achieved), the State organizes the national means and plans needed to successfully implement its decision while progressing towards Milestones 2 and 3. If the State is contemplating whether to conclude an additional protocol to its safeguards agreement with the IAEA, it will necessarily want to understand the con­tents of the Model Additional Protocol (INFCIRC/540 (Corrected)) (IAEA, 1997a). Due to their direct relevance to drawing a safeguards conclusion, the relevant articles of the AP which cover the provision of information and complementary access will be discussed further.
