U.S., Saudi Arabia Ink Historic Nuclear Partnership, Opening Door for American Reactor Exports

U.S. and Saudi Arabia Sign Landmark Civil Nuclear Accord

U.S. Energy Secretary Chris Wright and Saudi Energy Minister Prince Abdulaziz bin Salman have signed a sweeping peaceful nuclear cooperation agreement, known as a 123 agreement, alongside a companion bilateral safeguards pact. The documents, inked in the presence of senior officials, establish the legal framework for what both nations describe as a decades-long, multi-billion-dollar partnership in civil nuclear power.

The 123 agreement grants American companies broad access to Saudi Arabia’s future nuclear energy program, covering everything from reactor design and construction to fuel supply and operation. For the U.S., the deal is cast as a boon for domestic nuclear industry supply chains and workers, while Riyadh positions it as a pillar of its Vision 2030 push to diversify away from oil. Both capitals stress the agreements’ non-proliferation credentials, insisting they set “the highest standards of nuclear safety, security, and non-proliferation” and rely on U.S. technology and expertise.

While the text has not been released, the signing marks the culmination of years of negotiation that accelerated after the previous administration lifted a freeze on such talks. For Saudi Arabia, the pact unlocks the possibility of developing up to 17 gigawatts of nuclear power by 2040, enough to supply a large share of its electricity demand and future hydrogen and desalination projects. For the U.S., it is a chance to export its flagging civil nuclear capability at a moment when the White House is promoting a domestic nuclear renaissance.

Why the 123 Agreement Reshapes the Global Nuclear Market

The agreement redraws the competitive map for nuclear reactor exports in the Middle East, a region where Russian and Chinese state-backed vendors have already made inroads. Saudi Arabia’s program is the largest uncontracted civil nuclear market globally, and the 123 accord gives U.S. firms a preferential lane to bid.

A Door Opens for U.S. Nuclear Suppliers

The pact offers a lifeline for companies such as Westinghouse, which has struggled to find overseas orders since its AP1000 plants in the U.S. were completed. While Seoul has also supplied reactors to the region, Riyadh’s willingness to sign a 123 agreement with Washington signals a preference for U.S. technology in its first wave of plants—provided firms can deliver on price and schedule. The “multi-billion-dollar” framing is realistic: a single large reactor can cost $10–15 billion, and Saudi ambitions point to multiple units. However, the deal is not an exclusive contract; it establishes a legal framework that makes it easier for U.S. companies to obtain export licenses, but foreign competitors remain. The real test for U.S. nuclear exporters will be whether they can assemble financing packages that rival Russia’s state-supported export credit terms or South Korea’s turnkey offers.

Non-Proliferation Commitments and the Enrichment Precedent

A central question hanging over the agreement is whether it permits Saudi Arabia to enrich uranium or reprocess spent fuel domestically—activities that could, in theory, provide a pathway to weapons-grade material. Historically, U.S. 123 agreements have included a “gold standard” clause requiring partners to forgo enrichment and reprocessing. Saudi Arabia, which has long insisted it would seek enrichment rights if Iran obtains them, had pushed for a more permissive arrangement in earlier talks. The fact that the Department of Energy mentions a separate bilateral safeguards agreement suggests that enrichment and reprocessing are addressed, but the details are not yet public. If the agreement follows the traditional gold standard, it will be a significant non-proliferation win for Washington; if it allows enrichment, it could face sharp resistance in Congress, especially over fears of a regional nuclear arms race.

The pact also reinforces the geopolitical alignment between the two countries at a time when energy security and critical minerals are central to diplomacy. Saudi Arabia’s push for nuclear energy aligns with its goal of reducing domestic oil burn for power and freeing crude for export. For the U.S., the partnership helps lock in a long-term strategic relationship and provides a counterweight to Chinese and Russian influence in Gulf energy infrastructure.

Next Moves for U.S. Nuclear Industry and Policy Makers

• U.S. nuclear firms should prepare for a formal tender process. Companies like Westinghouse, Bechtel, and emerging SMR developers need to engage with the Department of Commerce and Export-Import Bank early to craft finance packages that can compete with rivals’ state-backed offers. Expect a request for proposals within 12–24 months, likely for a first two-unit station.
• Investors and financiers must assess long-term project risks. Nuclear builds are capital-intensive and span a decade or more; this opportunity is transformational over a horizon of 2030–2045, but near-term earnings impacts will be minimal. The project’s viability hinges on Saudi sovereign commitment and a stable regulatory framework, both of which appear solid.
• Congress and non-proliferation analysts should scrutinize the safeguards agreement. The bilateral safeguards text will determine whether enrichment and reprocessing rights were conceded. Lawmakers will have an opportunity to review the 123 agreement under existing law; any perceived weakening of the gold standard could stall approval.
• Saudi energy planners can now accelerate reactor site selection and grid integration studies. With the legal framework in place, the Kingdom can finalize its reactor technology choice, often a multi-year process itself. The agreement also opens a path to U.S. regulatory assistance for building a Saudi nuclear safety regulator from scratch.
