133. Editorial Note
On June 29, 1964 (15 UST 2128), July 15, 1965 (16 UST 888), and June 2, 1966 (17 UST 1966), the United States and the United Kingdom renewed their Agreement for Cooperation in the Civil Uses of Atomic Energy of June 15, 1955 (6 UST 2709). In June 1965 the United States suggested that the renewed agreement should contain provision for safeguards of the International Atomic Energy Agency on any material transferred. The British agreed to application of IAEA safeguards to enriched uranium purchased under a new agreement for use in the British civil power program. They also reserved their position in the event the United Kingdom joined Euratom for the application of Euratom safeguards on materials transferred under a new U.S.-U.K. Agreement for Cooperation in the Civil Power Applications of Atomic Energy, signed June 2, entered into force July 15, 1966 (17 UST 862). Because of the intermixture of British civil and military atomic energy programs, they could not agree on the application of international safeguards to highly enriched uranium purchased from the United States for use in their civil research and development program. Documentation on cooperation with the United Kingdom in the civil uses of atomic energy is in Department of State, Central Files, AE 4 UK-US.
