Information Assessment Team Advisories
Information Assessment Team Advisories (IATAs) provide critical, time-sensitive, threat-related information to specified licensees. IATAs may also suggest or request that recipients execute certain voluntary precautionary or protective actions. IATAs are issued whenever the U.S. Attorney General or the Secretary of the Department of Homeland Security makes a change in the National Terrorism Advisory System. NRC will issue a corresponding IATA elevating security at licenses.
IATAs may inform licensees when the FBI issues a Domestic Threat Advisory that is considered relevant to NRC licensees. IATAs inform licensees when a significant act of domestic terrorism, or other malevolent act, has occurred, and also inform licensees when NRC becomes aware of intelligence information regarding statements or actions taken by foreign persons or by terrorist organizations, or other threat-related information, relating to NRC-licensed facilities or activities.
