Research and development; weapons production; hazardous wastes; transfers of technologies

The Commission is authorized to—
(1)
conduct experiments and do research and development work in the military application of atomic energy;

under applicable law (other than this paragraph) and consistent with other missions of the Department of Energy, make transfers of federally owned or originated technology to State and local governments, private industry, and universities or other nonprofit organizations so that the prospects for commercialization of such technology are enhanced.
(b)

Material for Department of Defense use

Provided, howeverThe President from time to time may direct the Commission (1) to deliver such quantities of special nuclear material or atomic weapons to the Department of Defense for such use as he deems necessary in the interest of national defense, or (2) to authorize the Department of Defense to manufacture, produce, or acquire any atomic weapon or utilization facility for military purposes: , That such authorization shall not extend to the production of special nuclear material other than that incidental to the operation of such utilization facilities.

(c)

Sale, lease, or loan to other Nations of materials for military applications

The President may authorize the Commission or the Department of Defense, with the assistance of the other, to cooperate with another nation and, notwithstanding the provisions of section 2077, 2092, or 2111 of this title, to transfer by sale, lease, or loan to that nation, in accordance with terms and conditions of a program approved by the President—
(1)
nonnuclear parts of atomic weapons provided that such nation has made substantial progress in the development of atomic weapons, and other nonnuclear parts of atomic weapons systems involving Restricted Data provided that such transfer will not contribute significantly to that nation’s atomic weapon design, development, or fabrication capability; for the purpose of improving that nation’s state of training and operational readiness;
(2)
utilization facilities for military applications; and
(3)
source, byproduct, or special nuclear material for research on, development of, production of, or use in utilization facilities for military applications; and
(4)
Provided, howeverAnd provided further source, byproduct, or special nuclear material for research on, development of, or use in atomic weapons: , That the transfer of such material to that nation is necessary to improve its atomic weapon design, development, or fabrication capability: , That such nation has made substantial progress in the development of atomic weapons,
Provided, howeversection 2153 of this titleAnd provided furtherwhenever the President determines that the proposed cooperation and each proposed transfer arrangement for the nonnuclear parts of atomic weapons and atomic weapons systems, utilization facilities or source, byproduct, or special nuclear material will promote and will not constitute an unreasonable risk to the common defense and security, while such other nation is participating with the United States pursuant to an international arrangement by substantial and material contributions to the mutual defense and security: , That the cooperation is undertaken pursuant to an agreement entered into in accordance with : , That if an agreement for cooperation arranged pursuant to this subsection provides for transfer of utilization facilities for military applications the Commission, or the Department of Defense with respect to cooperation it has been authorized to undertake, may authorize any person to transfer such utilization facilities for military applications in accordance with the terms and conditions of this subsection and of the agreement for cooperation.
