§2157 Additional Export Criterion and Procedures

Summary

Exports of source and special nuclear materials, reactors or other production/utilization facilities, and sensitive nuclear technology to countries without nuclear weapons can only happen if those countries agree to IAEA safeguards on all their peaceful nuclear activities at the time of the export. The President must try to get those countries to follow this rule. The rule applies to export requests filed more than eighteen months after March 10, 1978, or when the first export would occur at least twenty-four months after that date. If the President says refusing an export would hurt U.S. non‑proliferation goals or security, a license may be issued anyway. But for exports of reactors, facilities, or fuel intended for them, the first such license for a country that has not met the rule must be sent to Congress for a 60‑day review. The submission must include a detailed explanation of the President’s decision, the executive branch judgment required under section 2155, and any Commission views, and be sent to the House Committee on Foreign Affairs and the Senate Committee on Foreign Relations. If Congress passes a concurrent resolution opposing the export during the 60 days, the export cannot happen. If Congress rejects opposition, the rule won’t be applied to that country unless Congress later disapproves under the process above; the first license after each twelve‑month period must be submitted for review.

The Public Health and Welfare, Source: USLM XML via OLRC

(a)(1)As a condition of continued United States export of source material, special nuclear material, production or utilization facilities, and any sensitive nuclear technology to non-nuclear-weapon states, no such export shall be made unless IAEA safeguards are maintained with respect to all peaceful nuclear activities in, under the jurisdiction of, or carried out under the control of such state at the time of the export.
(2)The President shall seek to achieve adherence to the foregoing criterion by recipient non-nuclear-weapon states.
(b)The criterion set forth in subsection (a) shall be applied as an export criterion with respect to any application for the export of materials, facilities, or technology specified in subsection (a) which is filed after eighteen months from March 10, 1978, or for any such application under which the first export would occur at least twenty-four months after March 10, 1978, except as provided in the following paragraphs:
(1)If the Commission or the Department of Energy, as the case may be, is notified that the President has determined that failure to approve an export to which this subsection applies because such criterion has not yet been met would be seriously prejudicial to the achievement of United States non-proliferation objectives or otherwise jeopardize the common defense and security, the license or authorization may be issued subject to other applicable requirements of the law: Provided, That no such export of any production or utilization facility or of any source or special nuclear material (intended for use as fuel in any production or utilization facility) which has been licensed or authorized pursuant to this subsection shall be made to any non-nuclear-weapon state which has failed to meet such criterion until the first such license or authorization with respect to such state is submitted to the Congress (together with a detailed assessment of the reasons underlying the President’s determination, the judgment of the executive branch required under section 2155 of this title, and any Commission opinion and views) for a period of sixty days of continuous session (as defined in section 2159(g) of this title) and referred to the Committee on Foreign Affairs of the House of Representatives and the Committee on Foreign Relations of the Senate, but such export shall not occur if during such sixty-day period the Congress adopts a concurrent resolution stating in substance that the Congress does not favor the proposed export. Any such license or authorization shall be considered pursuant to the procedures set forth in section 2159 of this title for the consideration of Presidential submissions.
(2)If the Congress adopts a resolution of disapproval pursuant to paragraph (1), no further export of materials, facilities, or technology specified in subsection (a) shall be permitted for the remainder of that Congress, unless such state meets the criterion or the President notifies the Congress that he has determined that significant progress has been made in achieving adherence to such criterion by such state or that United States foreign policy interests dictate reconsideration and the Congress, pursuant to the procedure of paragraph (1), does not adopt a concurrent resolution stating in substance that it disagrees with the President’s determination.
(3)If the Congress does not adopt a resolution of disapproval with respect to a license or authorization submitted pursuant to paragraph (1), the criterion set forth in subsection (a) shall not be applied as an export criterion with respect to exports of materials, facilities and technology specified in subsection (a) to that state: Provided, That the first license or authorization with respect to that state which is issued pursuant to this paragraph after twelve months from the elapse of the sixty-day period specified in paragraph (1), and the first such license or authorization which is issued after each twelve-month period thereafter, shall be submitted to the Congress for review pursuant to the procedures specified in paragraph (1): Provided further, That if the Congress adopts a resolution of disapproval during any review period provided for by this paragraph, the provisions of paragraph (2) shall apply with respect to further exports to such state.
