From the Document: "Secretary of Energy Rick Perry told Congress in late March that he had approved Part 810 authorizations for Saudi Arabia. Under U.S. law, nuclear-related exports require an export license or other authorization. The Atomic Energy Act (AEA) of 1954, as amended (P.L. 83-703; 42 U.S.C. §2153 et seq.), requires a peaceful nuclear cooperation agreement (known as a '123' agreement after the relevant section of the AEA) for the export of commodities under Nuclear Regulatory Commission (NRC) export licensing authority (10 C.F.R. 110). These include nuclear reactors and U.S.-origin special nuclear material, which the regulation defines as plutonium, uranium-233, or enriched uranium. The AEA also requires a 123 agreement for exports involving 'restricted data,' defined as 'all data concerning (1) design, manufacture, or utilization of atomic weapons; (2) the production of special nuclear material; or (3) the use of special nuclear material in the production of energy.'"
