Structural shifts in the energy sector are among the factors influencing the stability of major economies and their ability to manage long-term risks. In this context, the signing of a civilian nuclear cooperation agreement between Saudi Arabia and the United States, pursuant to Article 123 of the U.S. Atomic Energy Act, carries economic and strategic significance, as it could, under the announced arrangements, enable the development of domestic Saudi capabilities in parts of the nuclear fuel cycle, including enrichment for peaceful purposes, subject to the completion of the relevant legal and regulatory procedures.

The agreement’s full technical and economic details have not yet been published, and its entry into force is linked to review procedures in the U.S. Congress. Therefore, its ultimate economic impact will depend on the implementation framework, the ownership and operating model, technology-transfer conditions, and international safeguards.

Article 123 and the Changing Negotiating Framework

Under U.S. law, Article 123 agreements permit cooperation in civilian nuclear energy and the transfer of nuclear materials, technologies, and equipment, subject to nonproliferation and peaceful-use oversight requirements. In some agreements, the United States has adopted a negotiating approach requiring its partner to forgo uranium enrichment and the reprocessing of spent nuclear fuel—a policy approach known politically as the “gold standard.”

In the Saudi case, available information indicates that the agreement may open the way for consideration of establishing enrichment capacity inside the Kingdom, without necessarily implying the independent transfer of enrichment technology to the Saudi side or granting an unconditional right to operate it. According to published reports, the potential facility could be managed or supervised by the United States under a strict technical and regulatory model.

Economically, this arrangement gives the Kingdom a strategic option to reduce its future dependence on external nuclear-fuel services, but it does not automatically eliminate import costs or market risks. Achieving viability would require an integrated infrastructure encompassing mining, milling, conversion, enrichment, fuel fabrication, and the management of spent fuel and waste.

Fuel-Cycle Economics

If the commercial viability of extraction and processing is established, domestic uranium could provide an opportunity to move from exporting raw or minimally processed material toward developing an industrial and technological value chain with higher added value. However, domestic enrichment does not necessarily mean lower nuclear electricity costs.

Nuclear fuel typically accounts for a limited share of the total cost of electricity generation, while reactor construction, financing, operation, and maintenance costs are major components of a project’s overall economics. Establishing an enrichment facility also requires substantial capital, physical security and advanced monitoring systems, and specialized human expertise.

Accordingly, the clearest economic benefit in the initial phase may lie in security of supply and reduced exposure to geopolitical and logistical risks, rather than in achieving direct financial savings. The return on investment cannot be assessed before data are published on facility scale, financing costs, enrichment-service prices, domestic demand, and export potential.

Describing the project as establishing a “closed nuclear fuel cycle” also requires technical caution. A closed cycle requires, in addition to mining, conversion, and enrichment, arrangements for reprocessing spent fuel and reusing some of its components. It is therefore more accurate to speak of localizing parts of the nuclear fuel cycle.

Freeing Up Oil and the Opportunity Cost

One potential benefit of nuclear power is that it provides a stable source of electricity generation, helping reduce dependence on crude oil and fuel oil in power plants. This issue is particularly important in the Kingdom, where oil still contributes to the electricity mix alongside gas, with consumption rising during the summer months because of cooling demand and water desalination. Saudi Arabia generated approximately 453 terawatt-hours of electricity in 2023, with gas as the largest source at about 62%, compared with 38% for oil.

However, replacing oil will not result from nuclear power alone; natural gas, renewable energy, and improvements in power-plant efficiency are parallel pathways. The volume of oil savings will also depend on the number of reactors brought online, their capacity, their operating rates, and the alternatives they replace.

If this substitution occurs, some of the oil that would otherwise have been consumed domestically could be redirected toward exports or downstream industries such as petrochemicals. However, transportation, refining, and opportunity costs must be calculated accurately, rather than assuming that every barrel saved automatically becomes net revenue for the public treasury.

Investment and Industrial Localization

The nuclear agreement could provide a stronger legal framework for U.S. companies to participate in developing Saudi Arabia’s nuclear program, while also stimulating activity among construction, engineering, technical-services, and financing firms. However, signing the agreement alone does not guarantee an inflow of billions of dollars in foreign direct investment; that will depend on actual investment decisions, the financing model, the number of reactors, localization requirements, government guarantees, and the implementation timetable.

The broader benefit lies in the potential to build an industrial and knowledge base encompassing nuclear engineering, project management, safety, regulation, the manufacture of certain components, and the training of national personnel. This could support non-oil GDP if accompanied by clear knowledge-transfer programs, measurable localization targets, and effective private-sector participation.

Balancing Industrial Opportunity and Cost Control

Localizing mining, processing, and enrichment, if implemented within a clear peaceful-use and regulatory framework, offers an opportunity to strengthen energy-supply security and develop a new industrial and technological value chain in the Kingdom. However, financial viability should not be based on automatic assumptions about reducing electricity costs or generating export returns. Instead, it requires detailed studies comparing the cost of domestic production with the cost of imports and taking into account capital, financing, oversight, and waste-management costs.

Thus, the project’s most important economic impact may lie in diversifying the energy mix, reducing exposure to supply risks, and developing industrial and knowledge capabilities, along with the possibility of freeing up some of the liquid fuel used in electricity generation. By contrast, considering the Kingdom a nuclear-fuel exporter or describing the project as a closed fuel cycle should remain a future possibility conditional on economic viability, international approvals, and the ability to build an integrated industrial system.
