Summary

The Secretary of Defense must make rules or orders, after giving notice and a chance for public comment and subject to section 552(b)(3) of title 5, to stop people from sharing unclassified details about how special nuclear material is physically protected. The Secretary may only prohibit sharing if he finds that the unauthorized release could reasonably be expected to cause a significant harm to public health or safety or to the common defense and security by greatly increasing the chance of illegal nuclear-weapons production or the theft, diversion, or sabotage of nuclear material, equipment, or facilities. He may judge the risk by asking what the chance would be if the information were never available, and must use the smallest restrictions needed. The Secretary cannot use this authority to keep information from the proper Congressional committees. His decisions can be reviewed in court under section 552(a)(4)(B) of title 5. If the Department gives prohibited information to a State or local government, the Department keeps control of it and State or local disclosure laws do not apply.

(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 special 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.

(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)Nothing in this section shall be construed to authorize the Secretary to withhold, or to authorize the withholding of, information from the appropriate committees of the Congress.
