Appended to the guidelines was a two page “trigger list” based on the Zangger Committee’s list.

    George Vest to the Secretary, 'Nuclear Suppliers Status Report'

    In this document regarding the final agreement, George Vest wrote Kissinger that it “served to close many of the loopholes and inadequacies of previous nuclear cooperation agreements between suppliers and recipients.” It also put the French and West Germans on record to restrict access to sensitive nuclear technologies. Nevertheless, as Vest noted, the guidelines would not prevent “indigenous” development of nuclear capabilities and “unsafeguarded developments” or the acquisition of sensitive technology.

While the French were supportive of the moratorium proposal, the Germans were uncomfortable with it, not least because of the implications for their deal with Brazil.

  • August, 1977

    Central Intelligence Agency, Directorate of Intelligence, Office of Scientific Intelligence, 'South African Uranium Enrichment Program'

    With South Africa’s status as a pariah state, its nuclear program was a thorny problem for a series of U.S. presidents. In August 1977, the Carter administration, working with the Soviet Union, lodged protests against South Africa’s apparent preparations for a nuclear test, forcing a shut-down of the Kalahari test site if not the entire nuclear program itself. Indeed the CIA’s analysis of South Africa’s innovative “aerodynamic” uranium enrichment plant at Valindaba brought it to the conclusion that South Africa would be able to produce enough weapons-grade uranium “to make several nuclear devices per year.”

    State Department telegram 222114 to U.S. Embassy Paris, 'Nuclear Suppliers Meeting'

    This document reflects that while full-scope safeguards had wide support in the group, both the French and the West German remained opposed. The Carter administration tried to persuade the French but they were worried about being "isolated" in the group and talked about withdrawing or opposing further meetings because the NSG had “fully achieved” its objectives. Washington persuaded Paris not to withdraw, but the group’s future was plainly uncertain.

    This document describes the progress made up to that point and the various concerns of countries within the group regarding the scale of safeguards, particularly from the French and Germans. The NSG also agreed to make the guidelines available to the IAEA so that it could publish them. The State Department had been reluctant to publish them, not least because they did not include full scope safeguards, but overriding that was an interest in dispelling Third World concerns about a “secret cartel.”
