Nuclear Cooperation with Other Countries: A Primer

Summary
In order for the United States to engage in civilian nuclear cooperation with other states, it must
conclude a framework agreement that meets specific requirements under section 123 of the
Atomic Energy Act (AEA). The AEA also provides for exemptions to these requirements, export
control licensing procedures, and criteria for terminating cooperation. Congressional review is
required for section 123 agreements; the AEA establishes special parliamentary procedures by
which Congress may act on a proposed agreement.

Nuclear Cooperation with Other Countries: A Primer

What Is a “Section 123” Agreement?
Under existing law (Atomic Energy Act [AEA] of 1954; P.L. 95-242; 42 U.S.C. §2153 et seq.)1
all significant U.S. nuclear cooperation with other countries requires a peaceful nuclear
cooperation agreement.2 Significant nuclear cooperation includes the transfer of U.S.-origin
special nuclear material3 subject to licensing for commercial, medical, and industrial purposes.
Such agreements, which are “congressional-executive agreements” requiring congressional
approval, do not guarantee that cooperation will take place or that nuclear material will be
transferred, but rather set the terms of reference and authorize cooperation. The AEA includes
requirements for an agreement’s content, conditions for the President to exempt an agreement
from those requirements, presidential determinations and other supporting information to be
submitted to Congress, conditions affecting the implementation of an agreement once it takes
effect, and procedures for Congress to consider and approve the agreement.
Section 123 of the AEA requires that any agreement for nuclear cooperation meet nine
nonproliferation criteria and that the President submit any such agreement to the House
Committee on Foreign Affairs and the Senate Committee on Foreign Relations. The Department
of State is required to provide the President an unclassified Nuclear Proliferation Assessment
Statement (NPAS), which the President is to submit, along with the agreement, to those two
committees. The State Department is also required to provide a classified annex to the NPAS,
prepared in consultation with the Director of National Intelligence. The NPAS is meant to explain
how the agreement meets the AEA nonproliferation requirements. The President must also make a
written determination “that the performance of the proposed agreement will promote and will not
constitute an unreasonable risk to, the common defense and security.”

1 The Atomic Energy Act (AEA) was amended by the Nuclear Nonproliferation Act of 1978 (NNPA) (P.L. 95-242) to
include stringent nonproliferation requirements for significant U.S. nuclear exports. For example, the act required non-
nuclear-weapon states to have full-scope International Atomic Energy Agency safeguards as a condition for entering
into nuclear cooperation agreements with the United States. For existing and future agreements, the NNPA added a
provision for Congress to review export licenses. The act also included a provision for halting exports if a country
tested a nuclear device, violated safeguards agreements, or continued nuclear weapons-related activities.
2 Section 57 b. (2) of the AEA allows for limited forms of nuclear cooperation related to the “development or
production of any special nuclear material outside of the United States” without a nuclear cooperation agreement if that
activity has been authorized by the Secretary of Energy following a determination that it “will not be inimical to the
interest of the United States.” Agreements governing such cooperation are also known as “Section 810” agreements,
after 10 Code of Federal Regulations Part 810.
A nuclear cooperation agreement is not required for transmission of nuclear-related information, except for restricted
data. The term “restricted data,” as well as other terms used in the statute, is defined in 42 U.S.C. §2014. “Restricted
data” means “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.” Restricted data,
however does not “include data declassified or removed from the Restricted Data [sic] category” pursuant to the AEA.
A nuclear cooperation agreement is necessary, though not necessarily sufficient, to permit the transfer of restricted
data.
3 “Special nuclear material” means (1) plutonium, uranium enriched in the isotopes 233 or 235, and any other material
that is determined to be special nuclear material, but does not include source material, or (2) any material artificially
enriched by any of the foregoing, but does not include source material.

Requirements Under the Atomic Energy Act
Section 123 of the AEA specifies the necessary steps for engaging in nuclear cooperation with
another country:
Section 123a. states that the proposed agreement is to include the terms,
conditions, duration, nature, and scope of cooperation and lists nine criteria that
the agreement must meet. It also contains provisions for the President to exempt
an agreement from any of several criteria described in that section and includes
details on the kinds of information the executive branch must provide to
Congress.
Section 123b. specifies the process for submitting the text of the agreement to
Congress.
Section 123c. specifies how Congress approves cooperation agreements that are
limited in scope (e.g., do not transfer nuclear material or cover reactors larger
than 5 MWe). This report does not discuss such agreements.
Section 123d. specifies how Congress approves agreements that do cover
significant nuclear cooperation (transfer of nuclear material or reactors larger
than 5 MWe), including exempted agreements.
Section 123a., paragraphs (1) through (9), lists nine criteria that an agreement must meet unless
the President determines an exemption is necessary. These include guarantees that
• safeguards on transferred nuclear material and equipment continue in perpetuity;
• full-scope International Atomic Energy Agency (IAEA) safeguards are applied in
non-nuclear weapon states;
• nothing transferred is used for any nuclear explosive device or for any other
military purpose; except in the case of cooperation agreements with nuclear
weapon states, the United States has the right to demand the return of transferred
nuclear materials and equipment, as well as any special nuclear material
produced through their use, if the cooperating state detonates a nuclear explosive
device or terminates or abrogates an IAEA safeguards agreement;
• there is no retransfer of material or classified data without U.S. consent;
• physical security on nuclear material is maintained;
• there is no enrichment or reprocessing by the recipient state of transferred nuclear
material or nuclear material produced with materials or facilities transferred
pursuant to the agreement without prior approval;
• storage for transferred plutonium and highly enriched uranium is approved in
advance by the United States; and
• any material or facility produced or constructed through use of special nuclear
technology transferred under the cooperation agreement is subject to all of the
above requirements.

Exempted vs. Non-exempted Agreements
The President may exempt an agreement for cooperation from any of the requirements in Section
123a. if he determines that the requirement would be “seriously prejudicial to the achievement of
U.S. non-proliferation objectives or otherwise jeopardize the common defense and security.” The
AEA provides different requirements, conditions, and procedures for exempt and non-exempt
agreements.4 To date, all of the section 123 agreements in force are non-exempt agreements.5
Prior to the adoption of P.L. 109-401, the Henry J. Hyde United States-India Peaceful Atomic
Energy Cooperation Act of 2006, the President would have needed to exempt the nuclear
cooperation agreement with India from some requirements of Section 123 a. P.L. 109-401,
however, exempted nuclear cooperation with India from some of the AEA’s requirements.6
Congressional Review
Under the AEA, Congress has the opportunity to review a 123 agreement for two time periods
totaling 90 days of continuous session.7 The President must submit the text of the proposed
nuclear cooperation agreement, along with required supporting documents (including the
unclassified NPAS) to the House Foreign Affairs Committee and the Senate Foreign Relations
Committee. The President is to consult with the committees “for a period of not less than 30 days
of continuous session.” After this period of consultation, the President is to submit the agreement
to Congress, along with the classified annex to the NPAS and a statement of his approval of the
agreement and determination that it will not damage the national security interests of the United
States. This action begins the second period, of 60 days of continuous session. In practice, the
President has sent the agreement to Congress at the beginning of the full 90-day period, which
begins on the date of transmittal. Typically, the 60-day period has immediately followed the
expiration of the 30-day period. The President transmits the text of the proposed agreement along
with a letter of support with a national security determination, the unclassified NPAS, its
classified annex, and letters of support for the agreement from the Secretary of State and the
Nuclear Regulatory Commission.
If the President has not exempted the agreement from any requirements of section 123a., it
becomes effective at the end of the 60-day period unless, during that time, Congress adopts a joint
resolution disapproving the agreement and the resolution becomes law. If the agreement is an
exempted agreement, Congress must adopt a joint resolution of approval and it must become law

4 Nuclear cooperation agreements with nuclear weapon states recognized by the NPT are provided for in the AEA, and
are therefore non-exempt agreements. The NPT defines nuclear weapon states as those that exploded a nuclear weapon
or other nuclear explosive device prior to January 1, 1967: China, France, Russia, the United Kingdom, and the United
States.
5 The United States has concluded more than 20 bilateral nuclear cooperation agreements, as well as similar agreements
with the European Atomic Energy Community and the IAEA. See Nuclear Commerce: Governmentwide Strategy

Help Increase Commercial Benefits from U.S. Nuclear Cooperation Agreements with Other Countries,
Government Accountability Office, GAO-11-36, November 2010.
6 See CRS Report RL33016, U.S. Nuclear Cooperation with India: Issues for Congress, by Paul K. Kerr. The
agreement entered into force in December 2008.
7 When calculating periods of “continuous session” under the AEA, every calendar day is counted, including Saturdays
and Sundays. Only days on which either chamber has adjourned for more than three days pursuant to the adoption a
concurrent resolution authorizing the adjournment do not count toward the total. If Congress adjourns its final session
sine die, continuity of session is broken, and the count must start anew when it reconvenes.

by the end of the 60-day period or the agreement will not enter into force. At the beginning of this
60-day period, joint resolutions of approval or disapproval, as appropriate, are to be automatically
introduced in each house. During this period, the committees are to hold hearings on the proposed
agreement and “submit a report to their respective bodies recommending whether it should be
approved or disapproved.” If either committee has not reported the requisite joint resolution of
approval or disapproval by the end of 45 days, it is automatically discharged from further
consideration of the measure. After the joint resolution is reported or discharged, Congress is to
consider it under expedited procedures, as established by section 130.i. of the AEA.
Section 202 of P.L. 110-369, the United States-India Nuclear Cooperation Approval and
Nonproliferation Enhancement Act, which President Bush signed into law October 8, 2008,
amended section 123 of the AEA to require the President to keep the Senate Foreign Relations
Committee and the House Foreign Affairs Committee “fully and currently informed of any
initiative or negotiations relating to a new or amended agreement for peaceful nuclear
cooperation.”
Export Licensing
The AEA sets out procedures for licensing exports to states with whom the United States has
nuclear cooperation agreements. (Sections 126, 127, and 128 codified as amended at 42 U.S.C.
2155, 2156, 2157.) Each export of nuclear material, equipment, or technology requires a specific
export license or other authorization. The Nuclear Regulatory Commission (NRC) is required to
meet criteria in sections 127 and 128 in authorizing export licenses. These criteria are as follows:
• Application of IAEA safeguards to any material or facilities proposed to be
exported, material or facilities previously exported, and to any special nuclear
material used in or produced through the use thereof (these are not full-scope
safeguards, but safeguards required under Article III.2 of the nuclear
Nonproliferation Treaty [NPT]).
• Nothing exported can be used for any nuclear explosive device or for research on
or development of any nuclear explosive device.
• Recipient states must have adequate physical security on “such material or
facilities proposed to be exported and to any special nuclear material used in or
produced through the use thereof.”
• Recipient states are not to retransfer exported nuclear materials, facilities,
sensitive nuclear technology, or “special nuclear material produced through the
use of such material” without prior U.S. approval.
• Recipient states may not reprocess or alter in form or content exported nuclear
material or special nuclear material produced though the use of exported nuclear
material without prior U.S. approval.
• The foregoing conditions must be applied to any nuclear material or equipment
that is produced or constructed under the jurisdiction of the recipient by or
through the use of any exported sensitive nuclear technology.
• Section 128 requires that recipient non-nuclear-weapon states must have full-
scope IAEA safeguards.

The President must judge that the proposed export or exemption will “not be inimical to the
common defense and security” or that any export of that type “would not be inimical to the
common defense and security because it lacks significance for nuclear explosive purposes.” The
executive branch may also consider other factors, such as “whether the license or exemption will
materially advance the nonproliferation policy of the United States by encouraging the recipient
nation to adhere” to the NPT; whether “failure to issue the license or grant the exemption would
otherwise be seriously prejudicial” to U.S. nonproliferation objectives; and whether the recipient
nation has agreed to conditions identical to those laid out in Section 127.
Section 126b. (2) contains a provision for the President to authorize an export in the event that the
NRC deems that the export would not meet section 127 and 128 criteria. The President must
determine “that failure to approve an export would be seriously prejudicial to the achievement of
U.S. nonproliferation objectives or otherwise jeopardize the common defense and security.” In
that case, the President would submit his executive order, along with a detailed assessment and
other documentation, to Congress for 60 days of continuous session. After 60 days of continuous
session, the export would go through unless Congress were to adopt a concurrent resolution of
disapproval.8
Section 128b.(2) contains a provision for the President to waive termination of exports by
notifying the Congress that the state has adopted full-scope safeguards or that the state has made
significant progress toward adopting such safeguards, or that U.S. foreign policy interests dictate
reconsideration. Such a determination would become effective unless Congress were to adopt a
concurrent resolution of disapproval within 60 days of continuous session.
Additionally, section 129b.(1) forbids the export of “nuclear materials and equipment or sensitive
nuclear technology” to any country designated as a state sponsor of terrorism.9 Section 129b.(3)
allows the President to waive this provision.
Iran-Related Restrictions
The Comprehensive Iran Sanctions, Accountability, and Divestment Act of 2010 (P.L. 111-195),
which became law July 1, 2010, contains additional restrictions on licensing nuclear exports to
countries with entities that have been sanctioned for conducting certain types of energy-related
transactions with Iran. Section 102 a.(2)(A) of the law states that “no license may be issued for
the export, and no approval may be given for the transfer or retransfer” of “any nuclear material,
facilities, components, or other goods, services, or technology that are or would be subject to an
agreement for cooperation between the United States” and such countries. Section 102 a.(2)(B),
however, allows the President to waive these restrictions. Section 102 a.(2)(C), allows the

8 In light of the Supreme Court’s 1983 decision in INS v. Chadha, passing a concurrent resolution could invite a legal
challenge because it is arguably unconstitutional. Although not provided for in the AEA, Congress could choose to pass
a joint resolution of disapproval or a bill stating in substance it did not approve.
9 Section 129b. (2) states that the prohibitions described in the previous section “shall not apply to exports, reexports,
transfers, or retransfers of radiation monitoring technologies, surveillance equipment, seals, cameras, tamper-indication
devices, nuclear detectors, monitoring systems, or equipment necessary to safely store, transport, or remove hazardous
materials ... except to the extent that such technologies, equipment, seals, cameras, devices, detectors, or systems are
available for use in the design or construction of nuclear reactors or nuclear weapons.”

President to authorize licenses for nuclear exports “on a case-by-case basis” to entities (which
have not been sanctioned) in countries subject to the restrictions described above.10
Termination of Cooperation
Section 129a. of the AEA requires that the United States end exports of nuclear materials and
equipment or sensitive nuclear technology to any non-nuclear-weapon state that, after March 10,
1978, the President determines to have detonated a nuclear explosive device; terminated or
abrogated IAEA safeguards; materially violated an IAEA safeguards agreement; or engaged in
activities involving source or special nuclear material and having “direct significance” for the
manufacture or acquisition of nuclear explosive devices, and “has failed to take steps which, in
the President’s judgment, represent sufficient progress toward terminating such activities.”
Section 129a. also requires that the United States halt exports to any nation the President
determines to have materially violated the terms of an agreement for cooperation with the U.S.;
assisted, encouraged, or induced any non-nuclear weapon state to obtain nuclear explosives or the
materials and technologies needed to manufacture them; or re-transferred or entered into an
agreement for exporting reprocessing equipment, materials or technology to a non-nuclear
weapon state, unless in connection with an international agreement to which the United States
subscribes.
The President can waive termination of exports if he determines that “cessation of such exports
would be seriously prejudicial to the achievement of United States nonproliferation objectives or
otherwise jeopardize the common defense and security.” The President must submit his
determination to Congress, which is then referred to the House Committee on Foreign Affairs and
the Senate Foreign Relations Committee for 60 days of continuous session. The determination
becomes effective unless Congress adopts a joint resolution opposing the determination.
Legislation in the 112th Congress
On January 25, 2011, Senator John Ensign introduced “A bill to amend the Atomic Energy Act of
1954 to require congressional approval of agreements for peaceful nuclear cooperation with
foreign countries, and for other purposes” (S. 109). The bill was discharged from the Committee
on Finance and forwarded to the Committee on Foreign Relations on February 3. This bill would
change current congressional review requirements by mandating positive congressional approval
of all section 123 agreements. It would also require a joint resolution of approval for subsequent
arrangements (under Section 131 a(1)), and a nuclear proliferation assessment statement to be
submitted along with proposals for subsequent arrangements. Procedures for subsequent
arrangements to nuclear cooperation agreements are detailed in Section 131 of the Atomic Energy
Act. They refer to cooperation that, even after conclusion of a 123 agreement, would require
additional approval such as authorization for transfers of nuclear material or technology,
arrangements for physical security, storage or disposition of fuel, or enrichment or reprocessing
of nuclear materials transferred pursuant to the agreement.

S. 109 would also seek to strengthen congressional oversight of the negotiation of 123
agreements. The bill would require the President to keep the House Foreign Affairs Committee
and the Senate Foreign Relations Committee “fully and currently informed of any initiative or
negotiations” relating to a new or amended 123 agreement prior to public announcements. It
would also require the President to consult with relevant committees “not less than 15 calendar
days” after the start of negotiations, and on a monthly basis during negotiations.
