Title 42 › Chapter CHAPTER 23— - DEVELOPMENT AND CONTROL OF ATOMIC ENERGY › Subchapter SUBCHAPTER X— - INTERNATIONAL ACTIVITIES › § 2153a

Summary

Exports of source or special nuclear material from the United States must not be enriched after they leave the country unless the United States gives approval in advance, or an agreement for cooperation explicitly allows it. The approval process must follow the same steps used for proposed subsequent arrangements under section 2160. Any promises from the recipient that the Secretary of Energy and the Secretary of State think are needed to make sure approval will be obtained before enrichment must be made and included before the executive branch gives its export judgment. Material may not be sent for enrichment or reactor fuel to a nation (or group) that, after March 10, 1978, signed a new or changed agreement with the United States except under that agreement. Major critical components for uranium enrichment, fuel reprocessing, or heavy water production plants must be listed specifically in an agreement for cooperation before they can be exported under that agreement (except for agreements under sections 2121(c), 2164(b), or 2164(c)). "Major critical component" means parts the President decides are essential to operating a complete facility.

(a)Except as specifically provided in any agreement for cooperation, no source or special nuclear material hereafter exported from the United States may be enriched after export without the prior approval of the United States for such enrichment: Provided, That the procedures governing such approvals shall be identical to those set forth for the approval of proposed subsequent arrangements under section 2160 of this title, and any commitments from the recipient which the Secretary of Energy and the Secretary of State deem necessary to ensure that such approval will be obtained prior to such enrichment shall be obtained prior to the submission of the executive branch judgment regarding the export in question and shall be set forth in such submission: And provided further, That no source or special nuclear material shall be exported for the purpose of enrichment or reactor fueling to any nation or group of nations which has, after March 10, 1978, entered into a new or amended agreement for cooperation with the United States, except pursuant to such agreement.
(b)In addition to other requirements of law, no major critical component of any uranium enrichment, nuclear fuel reprocessing, or heavy water production facility shall be exported under any agreement for cooperation (except an agreement for cooperation pursuant to section 2121(c), 2164(b), or 2164(c) of this title) unless such agreement for cooperation specifically designates such components as items to be exported pursuant to the agreement for cooperation. For purposes of this subsection, the term “major critical component” means any component part or group of component parts which the President determines to be essential to the operation of a complete uranium enrichment, nuclear fuel reprocessing, or heavy water production facility.
