about mechanisms for assurance of supply and have been critical of additional criteria for accessing the fuel banks. Some reasons that non-nuclear weapon states have been reluctant to embrace these proposals include: a perception that the commercial or strategic interests of nuclear weapon states motivated the proposals a perception that the proposals produce a dependency on a limited number of nuclear fuel suppliers a perception that the proposal restricts their unalienable right to nuclear energy for peaceful purposes. One example of such a feared political-cutoff came after the 1979 Iranian Revolution. Germany halted construction of the Iranian Bushehr reactor, the United States cut off the supply of highly enriched fuel for the Tehran Research Reactor, and Iran never received uranium from France which it asserted it was entitled to. Russia also agreed not to provide an enrichment plant and terminated cooperation on several other nuclear-related technologies, including laser isotope separation. China terminated several nuclear projects in return in part for entry into force of a U.S.-China civil nuclear cooperation agreement. Ukraine agreed not to provide the turbine for the Bushehr reactor. These combined experiences contributed to an Iranian belief that foreign nuclear supplies are potentially subject to being interrupted. An international nuclear fuel bank would have to overcome this perception. History 1940–1969 The Report on the International Control of Atomic Energy, commonly known as the Acheson–Lilienthal Report, was written by a United States committee in 1946 and discussed possible methods for the international control of nuclear weapons and the avoidance of future nuclear warfare. The report was produced by the Committee on Atomic Energy, headed by Dean Acheson and David Lilienthal, and was mostly written by scientist Robert Oppenheimer. The report recommended that an international body, such as the United Nations, have control over both atomic materials and the means of producing nuclear energy. Bruno Pellaud, the IAEA's former deputy director-general for safeguards, says the fuel bank idea was developed as far back as 1957. The resulting Baruch Plan was a 1946 proposal by the United States government, written largely by political consultant Bernard Baruch. It was presented to the United Nations Atomic Energy Commission (UNAEC) at its first meeting in June 1946. The plan proposed to: extend between all nations the exchange of basic scientific information for peaceful ends; implement control of atomic energy to the extent necessary to ensure its use only for peaceful purposes; eliminate from national
