Transclassified Foreign Nuclear Information

Transclassified Foreign Nuclear Information (TFNI) is a real Department of Energy classification category, created by Atomic Energy Act §142(e) (42 U.S.C. 2162(e)). It lets DOE and the Director of National Intelligence jointly remove information about other nations' atomic energy programs from the Restricted Data category so it can be shared with the intelligence community, after which it is safeguarded as National Security Information while keeping certain atomic-energy protections — notably exemption from automatic declassification [S1][S2]. The category had no name until 2010, when it was formally designated TFNI under 32 CFR Part 2001 [S2].

Three properties decide most arguments that invoke it:

• It covers information, not materials. The "I" is Information; there is no category called "transclassified foreign nuclear materials."
• It is a category, not a classification level. Nothing is classified "at" TFNI.
• Its subject is foreign nuclear programs — not anomalous objects, not recovered hardware [S1][S3].

For contrast: Restricted Data is US nuclear weapon design and production information, classified "born secret" at creation; Formerly Restricted Data is US weapon-related military-application information jointly determined safe for DoD handling [S1].

TFNI enters UAP discussion through the Schumer-Rounds UAP Disclosure Act, whose findings section asserts that UAP records remain undeclassified partly because of an "over-broad interpretation" of TFNI. That the bill says so is established; the assertion itself is unproven, and the bill mentions neither debris nor NEST. The chain by which it became a claim about crash retrieval — statute, bill findings, David Grusch's interpretation, then two YouTube channels — is traced in the DOE weapons-lab lane research report.
