The following is the March 11, 2022, Congressional Research Service In Focus report AUKUS Nuclear Cooperation.
From the report
On December 1, 2021, President Joseph Biden submitted to Congress an “Agreement among Australia, the United Kingdom, and the United States for the Exchange of Naval Nuclear Propulsion Information.” This In Focus explains the agreement’s substance, as well as provisions of the Atomic Energy Act (AEA) of 1954, as amended (P.L. 83-703; 42 U.S.C. §§2153 et seq.), concerning the content and congressional review of such agreements.
An accompanying message to Congress explains that the agreement would permit the three governments to “communicate and exchange Naval Nuclear Propulsion Information and would provide authorization to share certain Restricted Data as may be needed during trilateral discussions” concerning a project to develop Australian nuclear-powered submarines. This project is part of an “enhanced trilateral security partnership” named AUKUS, which the three governments announced on September 15, 2021. The United States has a similar nuclear naval propulsion arrangement only with the United Kingdom pursuant to the bilateral 1958 Mutual Defense Agreement.
The partnership’s first initiative, according to a September 15 Joint Statement, is an 18-month study “to seek an optimal pathway to deliver” this submarine capability to Australia. This study is to include “building on” the U.S. and UK nuclear-powered submarine programs “to bring an Australian capability into service at the earliest achievable date.” The study is “in the early stages,” according to a November 2021 non-paper from Australia, the United Kingdom, and the United States, which adds that “[m]any of the program specifics have yet to be determined.”
Agreement Details
The agreement, which the governments signed on November 22, 2021, permits each party to exchange “naval nuclear propulsion information as is determined to be necessary to research, develop, design, manufacture, operate, regulate, and dispose of military reactors.” As noted, this information includes restricted data; the AEA defines such data to include “all data concerning … the use of special nuclear material in the production of energy.” The AEA and 10 C.F.R. Part 810.3 define special nuclear material as plutonium, uranium-233, or enriched uranium.
The agreement, which entered into force on February 8, 2022, is to remain in force until December 31, 2023, when it will “automatically extend for four additional periods of six months each.” Any party may terminate its participation in the agreement with six months written notice. Should any party abrogate or materially violate the agreement, the other parties may “require the return or destruction” of any transferred data.
The agreement includes provisions to protect transferred data. For example, no party may communicate any information governed by the agreement to any “unauthorized persons or beyond” the party’s “jurisdiction or control.” In addition, a recipient party communicating such information to nationals of a third AUKUS government must obtain permission from the originating party. The agreement includes an appendix detailing “security arrangements” to protect transferred information.
