What is the significance of "Formerly Restricted Data" (FRD)?

"Formerly Restricted Data" (FRD) refers specifically to defense-related information that was previously designated as "Restricted Data" under the Atomic Energy Act but has since been removed from that classification. This transition highlights a significant distinction in how sensitive information is managed and categorized within defense and nuclear sectors.

The significance of FRD lies in its ability to still be sensitive and important to national security while not requiring the same stringent controls as Restricted Data. By demarcating FRD from Restricted Data, it allows for more effective information sharing and dissemination among certain government and defense entities, as it recognizes that while the information was once considered crucial, it has reached a stage where its management can be less restrictive without compromising security objectives. This classification aids in ensuring that information is appropriately protected based on its current relevance and sensitivity to national security operations.
