Executive Order 12670—Nuclear Cooperation With EURATOM
By the authority vested in me as President by the Constitution and laws of the United States of America, including Section 126a(2) of the Atomic Energy Act of 1954, as amended (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 for 12-month periods by Executive Orders Nos. 12193, 12295, 12351, 12409, 12463, 12506, 12554, 12587, and 12629, failure to continue peaceful nuclear cooperation with the European Atomic Energy Community would be seriously prejudicial to the achievement of U.S. non-proliferation 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, 1990.
The White House,
