By the authority vested in me as President by the Constitution and statutes of the United States of America, including Section 126a(2) of the Atomic Energy Act of 1954, as amended (42 U.S.C. 2155(a)(2)), and having determined that, upon the expiration of the period specified in the first proviso to Section 126a(2) of such Act and extended by Executive Orders No. 12193, 12295, 12351, 12409 and 12463, failure to continue peaceful nuclear cooperation with the European Atomic Energy Community would be seriously prejudicial to the achievement of the United States nonproliferation objectives and would otherwise jeopardize the common defense and security of the United States, and having notified the Congress of this determination, I hereby extend the duration of that period to March 10, 1986.
