§2168 Dissemination of Unclassified Information

Title 42 › Chapter 23— DEVELOPMENT AND CONTROL OF ATOMIC ENERGY › Subchapter XI— CONTROL OF INFORMATION › § 2168

Last updated Apr 5, 2026|Official source

Summary

The Secretary of Energy must make rules or issue orders, after giving notice and a chance for public comment, to stop people from sharing certain unclassified atomic energy information. The kinds of information covered are designs of production or use facilities, security plans and measures for facilities or nuclear material (including in transit), and any weapon designs or parts that were taken out of restricted status under section 2162. The Secretary can only block sharing when he finds that doing so is needed because the information could reasonably be expected to seriously harm public health or safety or the nation’s defense by greatly raising the chance of illegal bomb-making or of theft, diversion, or sabotage of nuclear material, equipment, or sites. The Secretary must use the smallest limits needed and may consider how risky things would be if the information had never been available. The Secretary cannot use this authority to withhold information from the proper Congressional committees. Anyone who breaks these rules can be fined up to $100,000 for each violation, and the Secretary can reduce or cancel a fine. The procedures in section 2282(b) and (c) apply to these penalties. Rules or orders under this authority are also treated as issued under section 2201(b) for purposes of section 2273. Any decision about how this authority applies can be reviewed by a court under section 552(a)(4)(B) of title 5.

(C)the design, manufacture, or utilization of any atomic weapon or component if the design, manufacture, or utilization of such weapon or component was contained in any information declassified or removed from the Restricted Data category by the Secretary (or the head of the predecessor agency of the Department of Energy) pursuant to section 2162 of this title.
(2)The Secretary may prescribe regulations or issue orders under paragraph (1) to prohibit the dissemination of any information described in such paragraph only if and to the extent that the Secretary determines that the unauthorized dissemination of such information could reasonably be expected to have a significant adverse effect on the health and safety of the public or the common defense and security by significantly increasing the likelihood of (A) illegal production of nuclear weapons, or (B) theft, diversion, or sabotage of nuclear materials, equipment, or facilities.
(3)In making a determination under paragraph (2), the Secretary may consider what the likelihood of an illegal production, theft, diversion, or sabotage referred to in such paragraph would be if the information proposed to be prohibited from dissemination under this section were at no time available for dissemination.
(4)The Secretary shall exercise his authority under this subsection to prohibit the dissemination of any information described in paragraph (1) of this subsection—
(A)so as to apply the minimum restrictions needed to protect the health and safety of the public or the common defense and security; and
(B)upon a determination that the unauthorized dissemination of such information could reasonably be expected to result in a significant adverse effect on the health and safety of the public or the common defense and security by significantly increasing the likelihood of (i) illegal production of nuclear weapons, or (ii) theft, diversion, or sabotage of nuclear materials, equipment, or facilities.
(5)Nothing in this section shall be construed to authorize the Secretary to authorize the withholding of information from the appropriate committees of the Congress.
(b)(1)Any person who violates any regulation or order of the Secretary issued under this section with respect to the unauthorized dissemination of information shall be subject to a civil penalty, to be imposed by the Secretary, of not to exceed $100,000 for each such violation. The Secretary may compromise, mitigate, or remit any penalty imposed under this subsection.
(2)The provisions of subsections (b) and (c) of section 2282 of this title, shall be applicable with respect to the imposition of civil penalties by the Secretary under this section in the same manner that such provisions are applicable to the imposition of civil penalties by the Commission under subsection (a) of such section.
(c)For the purposes of section 2273 of this title, any regulation prescribed or order issued by the Secretary under this section shall also be deemed to be prescribed or issued under section 2201(b) of this title.
(d)Any determination by the Secretary concerning the applicability of this section shall be subject to judicial review pursuant to section 552(a)(4)(B) of title 5.
