Executive Order 12903: Nuclear Cooperation With EURATOM
President: Bill Clinton
Extended a statutory waiver allowing peaceful nuclear cooperation with Euratom through March 10, 1995 while a modern agreement was negotiated; that temporary period expired.
Status: Superseded. Is Executive Order 12903 still in effect? No. Executive Order 12903 was superseded. See Federal Register record.
What does Executive Order 12903 do?
EO 12903 made the finding required by section 126a(2) of the Atomic Energy Act that interrupting peaceful nuclear cooperation with Euratom would seriously prejudice nonproliferation objectives and jeopardise common defense and security. It therefore extended the statutory period for one year, superseding EO 12840. This was one link in an annual series, not permanent authority. A new U.S.–Euratom cooperation agreement entered into force on April 12, 1996 and now operates with rolling extensions.
Before and after
