Executive Order 12629

Nuclear Cooperation With EURATOM

This executive order extends U.S. peaceful nuclear cooperation with the European Atomic Energy Community (EURATOM) for another 12-month period, through March 10, 1989, based on a presidential determination that discontinuing cooperation would harm non-proliferation goals and U.S. national security. It supersedes the previous extension order (EO 12587) upon taking effect.

Key directives

  • Extend peaceful nuclear cooperation period with EURATOM to March 10, 1989

Timeline

Immediate

  • Supersession of EO 12587 upon effective date
  • Continuation of nuclear cooperation authority

Near term (90d)

  • Congressional notification already completed per text
  • Ongoing nuclear trade and technology transfers under extended framework

Long term

  • Cooperation expires March 10, 1989 unless further extended
  • Potential pattern of recurring annual extensions

Risks & tensions

  • Recurring annual extensions since 1980 (EO 12193 onward) suggest structural reliance on stopgap measures rather than permanent agreement
  • Congressional notification completed but no explicit consultation requirement for future extensions
  • Vague 'effective date' not specified as signing date; may allow brief administrative gap
