A State-level safeguards approach is a safeguards approach developed for a specific State, encompassing all nuclear material, nuclear installations and nuclear fuel cycle related activities in that State. A State level safeguards approach defines the application of safeguards measures at each facility and location outside facilities in the State and, where an additional protocol is in force, the safeguards measures that would enable the IAEA to draw and maintain a conclusion of the absence of undeclared nuclear material and activities in that State. Historically, safeguards approaches have been done for specific facilities only, however, the IAEA is transitioning to state-level safeguards approaches as a mechanism for increased efficiency.
