The Role of the Nuclear Regulatory Commission in Facilitating International Nuclear Cooperation Agreements

The Nuclear Regulatory Commission (NRC) serves as the primary regulatory authority for civilian nuclear activities in the United States, but its influence extends far beyond American borders. Through active participation in international nuclear cooperation agreements, the NRC helps set global standards for safety, security, and non-proliferation. These agreements, often formalized under Section 123 of the U.S. Atomic Energy Act, allow other nations to access American nuclear technology and materials while ensuring they meet rigorous U.S. and international requirements. The NRC’s work in this arena is indispensable for fostering the peaceful use of nuclear energy worldwide, preventing the spread of nuclear weapons, and building trust among partner nations.

In an era where nuclear energy is increasingly viewed as a critical tool for decarbonization and energy security, the NRC’s international role has never been more important. By providing technical expertise, conducting independent reviews, and sharing regulatory best practices, the NRC helps ensure that nuclear cooperation agreements deliver their intended benefits without compromising safety or security. This article explores the NRC’s multifaceted responsibilities, the legal and institutional frameworks that guide its international engagements, the specific roles it plays in agreement facilitation, and the challenges and opportunities that lie ahead.

The NRC’s Domestic Foundation and Global Reach

The NRC was established in 1974 as an independent agency to regulate commercial nuclear power plants, the use of nuclear materials in medicine and industry, and the security of nuclear facilities. Its core mission is to protect public health and safety, promote the common defense and security, and protect the environment. To fulfill this mission, the NRC develops regulations, issues licenses, conducts inspections, and enforces compliance for all civilian nuclear activities within the United States.

While the NRC’s primary focus is domestic, the global nature of the nuclear industry requires extensive international collaboration. Nuclear fuel cycles transcend borders; radioactive materials are transported internationally, reactor designs are shared, and safety incidents in one country can affect confidence worldwide. Consequently, the NRC has built a robust international program that engages with foreign regulatory bodies, international organizations, and partner governments. This program is essential for ensuring that U.S.-supplied nuclear technology and materials are used safely and for peaceful purposes—a core tenet of U.S. non-proliferation policy.

The NRC’s international activities are grounded in several key legal authorities. The most prominent is Section 123 of the U.S. Atomic Energy Act, which requires that any significant transfer of nuclear material, equipment, or technology from the United States to another country be governed by a peaceful nuclear cooperation agreement. These agreements, often called “123 agreements,” must be signed by the President and reviewed by Congress. They set forth terms for cooperation, including commitments to non-proliferation, safeguards, and physical security.

The NRC plays a central role in the implementation of 123 agreements. It reviews proposed transfers to ensure they comply with the agreement’s terms and U.S. laws, assesses the regulatory capabilities of partner countries, and provides technical assistance to strengthen their oversight. The NRC’s international activities page details how the agency works with the State Department, the Department of Energy, and other agencies to negotiate and uphold these agreements.

In addition to 123 agreements, the NRC participates in multilateral treaties such as the Treaty on the Non-Proliferation of Nuclear Weapons (NPT), the Convention on Nuclear Safety, and the Joint Convention on the Safety of Spent Fuel Management and on the Safety of Radioactive Waste Management. Through these instruments, the NRC contributes to a global safety culture and helps set standards that all nations can adopt.

Key Roles in Facilitating International Agreements

The NRC’s involvement in international nuclear cooperation agreements can be grouped into several critical functions. Each role ensures that the agreements are not merely paper documents but operational realities that uphold safety and security.

Review and Approval of Transfers

Before any U.S. nuclear technology or material can be exported to a foreign partner, the NRC must review the proposed transaction. This review encompasses a thorough evaluation of the recipient country’s regulatory infrastructure, its track record on non-proliferation, and its ability to safely handle the material or equipment. The NRC also verifies that the transfer complies with the specific terms of the applicable 123 agreement. In some cases, the NRC issues specific licenses or approvals, and it may attach conditions to ensure ongoing compliance.

This review process is not a rubber stamp. The NRC evaluates the technical competence of the foreign entity, the security measures in place, and the adequacy of the host nation’s regulatory oversight. For example, before allowing the export of a research reactor or nuclear fuel, the NRC assesses whether the recipient country has the necessary safety systems and trained personnel. This rigorous approach helps prevent accidents and deters misuse of nuclear materials.

Information Sharing and Regulatory Cooperation

Effective nuclear regulation depends on the free exchange of technical information, operational experience, and lessons learned. The NRC actively shares its regulatory knowledge with international counterparts through bilateral and multilateral channels. One of the most important forums is the International Atomic Energy Agency (IAEA), where the NRC contributes to developing safety standards, conducting peer reviews, and participating in training programs.

For instance, the NRC participates in the IAEA’s Integrated Regulatory Review Service (IRRS), which sends international teams to review a country’s regulatory framework. Conversely, the NRC hosts IRRS missions to the United States and invites foreign regulators to observe its processes. The IAEA’s IRRS page provides more details on how these missions strengthen regulatory infrastructure.

Additionally, the NRC engages in bilateral exchanges with countries as diverse as Japan, South Korea, and the United Arab Emirates. These exchanges cover everything from reactor design certification to emergency response planning. By sharing its experience, the NRC helps other nations build effective regulatory systems, which in turn increases the safety of U.S.-origin technology abroad.

Technical Assistance and Capacity Building

Many countries seeking to develop or expand nuclear power programs lack the regulatory infrastructure to oversee such facilities safely. The NRC provides technical assistance to help these nations build competent regulatory bodies. This assistance can include training courses on inspection techniques, guidance on writing regulations, and workshops on safety culture.

A prominent example is the NRC’s collaboration with the U.S. Department of Energy’s National Nuclear Security Administration (DOE/NNSA) under the Global Threat Reduction Initiative and related programs. The NRC sends experts to countries to advise on regulatory development, assists in drafting laws and regulations, and conducts tabletop exercises to test emergency plans. The DOE/NNSA website outlines these cooperative efforts.

Capacity building is particularly important for countries with nascent nuclear programs. The NRC’s support helps them avoid common pitfalls, such as inadequate oversight or insufficient staffing, that can lead to accidents or security lapses. By strengthening foreign regulatory systems, the NRC also protects U.S. interests, because poorly regulated nuclear facilities anywhere in the world pose a risk to global security.

Inspection and Oversight of International Facilities

Under some 123 agreements, the NRC may conduct inspections of nuclear facilities in partner countries that use U.S.-origin material or equipment. These inspections verify compliance with the terms of the agreement, including commitments to operate safely, maintain physical protection, and allow IAEA safeguards. While the IAEA has primary responsibility for verifying non-proliferation through safeguards inspections, the NRC’s role complements these efforts by focusing on safety and security from a regulatory perspective.

The NRC also participates in international observation missions for nuclear power plant construction and commissioning. For example, when a U.S.-designed reactor is built abroad, the NRC may review the foreign regulator’s oversight of the project and offer advice. This involvement helps ensure that the same high safety standards applied in the United States are upheld overseas.

Case Studies in NRC-Facilitated Cooperation

The U.S.-India Civil Nuclear Agreement

One of the most significant nuclear cooperation agreements in recent decades is the U.S.-India Civil Nuclear Agreement, signed in 2008. This agreement allowed India, which is not a party to the NPT, to access U.S. nuclear technology and fuel for civilian use. The NRC played a critical role in implementing this agreement by reviewing India’s regulatory framework, helping to separate civilian and military nuclear facilities, and ensuring that U.S. nuclear exports to India would be covered by IAEA safeguards.

The NRC provided technical assistance to India’s Atomic Energy Regulatory Board (AERB) through workshops and exchanges. It also evaluated India’s commitment to a nuclear liability regime, which was a major point of negotiation. The agreement has since enabled a number of reactor projects and fuel supply arrangements, demonstrating how the NRC’s involvement can bridge gaps between countries with different legal and regulatory traditions.

The U.S.-UAE Peaceful Uses of Nuclear Energy Agreement

The United Arab Emirates (UAE) is another notable partner in nuclear cooperation. The 2009 U.S.-UAE 123 agreement set a gold standard for non-proliferation by including a legally binding commitment from the UAE to forgo domestic enrichment and reprocessing of nuclear fuel—a so-called “gold standard” clause. The NRC worked closely with the UAE’s Federal Authority for Nuclear Regulation (FANR) to help establish its regulatory framework from scratch.

NRC experts participated in training FANR inspectors, developing regulations consistent with international best practices, and reviewing the safety case for the Barakah nuclear power plant. Today, Barakah operates using U.S.-origin technology, and the UAE’s regulatory system is widely regarded as one of the most robust in the Middle East. This case exemplifies how the NRC’s technical assistance can enable a country to safely introduce nuclear power while maintaining strong non-proliferation standards.

Challenges Facing the NRC’s International Engagement

Despite its successes, the NRC faces several challenges in facilitating international nuclear cooperation agreements. These issues require constant attention and adaptation.

Balancing Non-Proliferation with Peaceful Use

The fundamental tension in nuclear cooperation is between promoting the peaceful use of nuclear energy and preventing the spread of weapons-usable materials. Every 123 agreement must strike this balance, but the NRC must carefully evaluate each proposed transfer to ensure it does not inadvertently facilitate proliferation. This challenge is magnified when dealing with countries that have ambiguous nuclear ambitions or that possess sensitive technologies, such as enrichment or reprocessing capabilities.

The NRC must also navigate the differing interpretations of non-proliferation commitments among partner countries. For example, some nations seek to acquire enrichment capabilities under the guise of peaceful use, while the United States prefers to limit such capabilities to prevent proliferation. The NRC’s review process is one of the key tools for enforcing U.S. policy on these matters.

Export Control Complexity

Export controls for nuclear-related items are highly detailed and subject to change. The NRC must ensure that it has up-to-date knowledge of both U.S. export control regulations and the international regimes that govern them, such as the Nuclear Suppliers Group (NSG) guidelines. Mistakes in licensing can lead to legal penalties or damage international relationships. Moreover, the NRC must coordinate with multiple federal agencies, including the Department of Commerce and the Department of State, which have overlapping jurisdictions.

Streamlining export control processes without weakening oversight remains an ongoing challenge. The NRC has taken steps to improve efficiency, such as developing an online licensing system and providing guidance documents for applicants, but the complexity of the rules can still slow down cooperation.

Political and Diplomatic Hurdles

Nuclear cooperation is inherently political. Agreements can be delayed or canceled due to changes in government, tense diplomatic relations, or disagreements over non-proliferation obligations. The NRC does not negotiate agreements itself—that is the role of the executive branch—but its technical assessments can become politicized if they are perceived as either too restrictive or too lax.

For instance, negotiations with some countries have stalled over liability provisions, safety inspections, or the status of military nuclear facilities. The NRC must maintain its independence and technical credibility even as it works within a political environment. Its ability to provide objective, science-based evaluations helps depoliticize some of these issues, but it cannot fully insulate itself from geopolitical turbulence.

Resource Constraints and Capacity

The NRC’s international program competes for resources with its domestic responsibilities. As the number of countries seeking nuclear cooperation grows, the NRC must do more with finite staff and funding. The agency has sought to leverage partnerships with other U.S. agencies and international organizations to stretch resources, but there is a limit to how much workload can be absorbed.

The increasing complexity of nuclear technology—such as small modular reactors (SMRs) and advanced reactors—also requires the NRC to develop new expertise. Training foreign regulators on these new designs demands additional resources. Without adequate funding, the NRC may struggle to maintain its leadership role in international regulatory cooperation.

Opportunities for Strengthening Global Nuclear Cooperation

While challenges exist, the NRC also has opportunities to enhance its impact and help shape a safer, more sustainable nuclear future.

Harmonizing Safety and Security Standards

One of the greatest opportunities is the continued harmonization of nuclear safety and security standards across countries. When regulators adopt consistent requirements, it becomes easier for nations to cooperate confidently. The NRC can promote harmonization by sharing its regulatory framework, participating in international standard-setting bodies, and encouraging the use of IAEA safety standards as a baseline.

For emerging nuclear countries, the NRC’s guidance can accelerate the development of a sound regulatory system, reducing the time and cost of bringing new reactors online while maintaining high safety levels. The adoption of common standards also simplifies the licensing of U.S.-designed reactors abroad, benefiting American exporters and fostering a level playing field.

Supporting Climate Goals Through Nuclear Expansion

The global push to decarbonize electricity generation has led to renewed interest in nuclear power. Many countries are considering building new reactors to replace fossil fuel plants. The NRC’s international cooperation agreements are vital for enabling these projects, especially for nations that lack domestic regulatory expertise.

By ensuring that new reactors meet world-class safety standards, the NRC helps make nuclear energy a credible and reliable option in the fight against climate change. The agency can also advocate for a regulatory environment that facilitates innovation, such as the deployment of SMRs and advanced reactors, which promise lower costs and improved safety. The NRC’s advanced reactor page provides information on how the agency is preparing for these technologies.

Strengthening the Global Nuclear Security Framework

Nuclear security—the prevention of theft, sabotage, and unauthorized access—is an area where the NRC can deepen its international engagement. The agency has already contributed to the IAEA’s Nuclear Security Guidance Committee and participated in international tabletop exercises. By expanding these activities, the NRC can help partner countries implement robust physical protection, cybersecurity, and material control measures.

The NRC is also well-positioned to assist countries in complying with the Amendment to the Convention on the Physical Protection of Nuclear Material, which strengthens international obligations for protecting nuclear materials and facilities. Providing training and assessment services in this area could become a major component of the NRC’s international program.

Leveraging Digital Tools for Collaboration

Advances in communication technology offer new ways for the NRC to collaborate with foreign regulators. Virtual workshops, web-based training modules, and shared databases can extend the NRC’s reach without requiring extensive travel. The agency could develop a virtual regulatory assistance platform that provides on-demand resources for countries developing their nuclear programs.

Such tools could also facilitate regular peer reviews and knowledge sharing, making international cooperation more efficient and continuous. While face-to-face interactions remain valuable, digital tools can supplement them and ensure that assistance is available when needed.

Conclusion: The NRC’s Enduring Role in Global Nuclear Governance

The Nuclear Regulatory Commission’s involvement in international nuclear cooperation agreements is a cornerstone of the global nuclear governance architecture. By reviewing and approving transfers, sharing information, providing technical assistance, and conducting oversight, the NRC ensures that U.S. nuclear exports contribute to the peaceful, safe, and secure use of nuclear energy worldwide. This role not only protects U.S. national security but also strengthens the overall international non-proliferation regime.

The challenges of political complexity, resource constraints, and the need to balance competing objectives are significant, but the NRC has consistently demonstrated its ability to adapt and innovate. Looking ahead, the agency has the opportunity to lead in harmonizing standards, supporting climate-friendly nuclear expansion, and enhancing nuclear security. As more nations turn to nuclear energy, the NRC’s expertise and commitment to safety will remain indispensable.

International nuclear cooperation is not a one-time achievement but a continuous process of building trust, sharing knowledge, and enforcing commitments. The NRC, through its dedicated international program, helps sustain that process, ensuring that nuclear technology remains a force for good in an increasingly interconnected world.
