In September, the Nuclear Suppliers' Group reaches agreement on export controls of sensitive nuclear technology, issuing a list called the “London Guidelines” that the IAEA later publishes. In Vienna, the International Nuclear Fuel Cycle Evaluation (INFCE) begins a multi-year assessment of problems associated with peaceful uses of nuclear energy and any risk they may pose of further proliferation. In Salzburg, Austria, nearly 2000 delegates attend the IAEA conference on nuclear power and its fuel cycle.
