Section 123 of the U.S. Atomic Energy Act  requires the conclusion of a specific agreement for significant transfers of nuclear material, equipment, or components from the United States to another nation. Section 123 Agreements are important tools in advancing U.S. nonproliferation principles. These Agreements act in conjunction with other nonproliferation tools, particularly the Nuclear Nonproliferation Treaty, to establish the legal framework for significant nuclear cooperation with other countries. Moreover, the Agreements allow for cooperation in other areas, such as technical exchanges, scientific research, and safeguards discussions. In order for a country to enter into such an Agreement with the United States, that country must commit itself to adhering to U.S.- mandated nuclear nonproliferation norms.
