IAEASafeguards

IAEA safeguards are a set of verification activities conducted by the International Atomic Energy Agency with the aim of verifying that a state's nuclear materials and activities are used exclusively for peaceful purposes. Safeguards form a central pillar of the global nuclear non-proliferation regime and are implemented under legally binding agreements between the IAEA and individual states. The primary framework is provided by Comprehensive Safeguards Agreements under the Treaty on the Non-Proliferation of Nuclear Weapons (NPT), complemented by the Additional Protocol, which expands information sharing and inspection authority.

Core elements include information analysis, routine and ad hoc inspections, item counting and material balance, facility registration and containment and surveillance measures, and, where applicable, remote monitoring and environmental sampling. Inspections verify declared inventories and flows of nuclear material, while safeguards data are analyzed to detect anomalies or undeclared activities. The State-level concept integrates all safeguards-relevant information for a given state, including all facilities and programs, to assess proliferation risk.

Implementation varies by country and facility type, but generally involves scheduled inspections, continuous or semi-continuous monitoring, and verification of declared quantities of nuclear material. Safeguards aim to provide assurance to the international community while protecting sensitive information.

Limitations include the possibility of undisclosed activities, measurement uncertainties, and political or resource constraints. Ongoing developments focus on strengthening the Additional Protocol, expanding state-level approaches, and adapting to new technologies to improve detection and reporting.
