Security Orders

Security orders contain requirements for licensees to implement interim compensatory security measures beyond that currently required by NRC regulations and as conditions of licenses. Some of the requirements formalize a series of security measures that licensees took in response to advisories NRC issued in the aftermath of the September 11 terrorist attacks. Other requirements reflect additional security enhancements that have emerged from NRC's ongoing comprehensive security review.

Note: The documents on this Web page do not include any specific compensatory measures. Specific compensatory security requirements were addressed in separate attachments to the orders and these attachments have not been released to the public because they contain safeguards information. Safeguards information is sensitive security information that is not shared with the public.
