Saudi Arabia Nuclear Deal Negotiations on 20% Enrichment

What happened

The United States and Saudi Arabia signed a civilian nuclear cooperation agreement on July 22, 2026 2. The U.S. Department of Energy characterized the deal as a "historic" bilateral safeguards framework intended to facilitate technology transfer 2. Energy Secretary Chris Wright stated the agreement integrates commerce, prosperity, and security 2. The deal now awaits review by the U.S. Congress 2.

On September 14, 2026, International Atomic Energy Agency (IAEA) Director General Rafael Grossi met with Saudi Energy Minister Prince Abdulaziz bin Salman in Vienna during the IAEA’s 70th General Conference 1. Grossi confirmed Saudi Arabia is advancing its nuclear power program and research reactor with a "strong commitment to non-proliferation" 1. Prince Abdulaziz stated the program adheres to international standards of transparency and is not conducted in hidden facilities 1.

Saudi Arabia also reported progress on domestic resource assessment. Exploration at the Jabal Sayid project in Madinah identified approximately 110 million tons of ore containing rare earth elements and uranium deposits 1.

What changed vs. the baseline

The primary change is the formalization of the Section 123 Agreement on July 22, 2026, which provides the legal framework for U.S. firms to export nuclear technology and fuel to Saudi Arabia 2. Previously, U.S. vendors like GE Hitachi and Toshiba-Westinghouse were legally ineligible to compete for Saudi contracts due to the absence of this government-to-government framework 2.

The baseline uncertainty regarding the IAEA Additional Protocol remains partially unresolved. While the July 22 deal includes a "bilateral safeguards framework," and Prince Abdulaziz reaffirmed a commitment to "international standards and obligations," the specific adoption of the Additional Protocol was not explicitly confirmed in the September 14 Vienna meeting 1, 2.

Saudi Arabia’s infrastructure focus has shifted. While the baseline noted the Nuclear Framework Office at K.A.CARE as the lead, the Nuclear Holding Company is now actively managing the procurement of two 1.4 GWe reactors at Duwaiheen 2.

Why it matters

The 123 Agreement places U.S. nuclear vendors on a level legal footing with competitors from China, Russia, and South Korea for the first time in over a decade 2. While the large-scale Duwaiheen units are already in a multi-vendor bidding process involving international players, the U.S. deal specifically opens the market for Small Modular Reactors (SMRs) 2.

SMRs are prioritized for Saudi Arabia’s specific grid requirements, which include:

• Desalination: The Kingdom requires 11 million cubic meters of desalinated water daily; SMRs allow for cogeneration 2.
• Grid Compatibility: The Saudi 60 Hz grid is isolated; SMRs provide firm domestic capacity without the $20 billion upfront commitment required for gigawatt-scale plants 2.
• Industrial Decarbonization: Near-term U.S. contracts are expected to focus on industrial zones and the NEOM project rather than primary grid-scale power 2.

Open questions

• Congressional Review: The 123 Agreement must still pass through the U.S. Congressional review period, where non-proliferation terms—specifically regarding domestic enrichment—may face scrutiny 2.
• Safeguards Transition: It is not yet confirmed if Saudi Arabia has formally rescinded its Small Quantities Protocol (SQP) in favor of a Comprehensive Safeguards Agreement (CSA) and the Additional Protocol 1.
• Uranium Economic Viability: While 110 million tons of ore have been identified at Jabal Sayid, the economic feasibility of extracting and utilizing these uranium deposits remains under assessment 1.

What happened

The White House formally submitted the U.S.-Saudi 123 Agreement, a Bilateral Safeguards Agreement (BSA), and a Nuclear Proliferation Assessment Statement (NPAS) to Congress on August 24, 2026 3. This submission followed the official signing of the civilian nuclear cooperation pact on July 22, 2026 3. The agreement reportedly includes provisions for domestic uranium enrichment, a departure from previous U.S. policy for non-nuclear-weapon states 3.

On September 14, 2026, Saudi Energy Minister Prince Abdulaziz bin Salman addressed the 70th IAEA General Conference in Vienna 1. He stated the Saudi nuclear program is "peaceful and transparent" and operates within international regulatory frameworks 1. The Minister confirmed the National Atomic Energy Project is currently exploring uranium resources, specifically citing the Jabal Sayid project in Madinah, which contains an estimated 110 million tons of ore with rare earth minerals and uranium deposits 1.

In July 2026, a commercial arrangement was finalized allowing U.S. firms to manage civilian nuclear operations in the Kingdom, with a specific focus on providing power for AI data centers 4.

What changed vs. the baseline

The primary change is the formalization and congressional submission of the 123 Agreement. In early 2026, the deal was only a reported possibility involving enrichment concessions 8. As of September 2026, the text is signed and under active congressional review 3.

The U.S. position on enrichment has shifted significantly. While the 2009 "Gold Standard" agreement with the UAE renounced domestic enrichment, the current Saudi deal provides a pathway toward these capabilities 3. Negotiations in November 2025 and April 2026 moved the deal forward without requiring Saudi-Israeli normalization as a prerequisite, a shift from earlier Biden administration efforts 3.

It is not new that Saudi Arabia is seeking nuclear power for diversification. The National Project for Atomic Energy was approved in July 2017, and the bidding process for two 1.4 GWe reactors at Khor Duweihin began in May 2022 2. The list of approved bidders—China National Nuclear Corporation, EDF, KEPCO, and Rosatom—has remained consistent since July 2024 2.

Why it matters

The submission to Congress initiates the statutory review period required for the agreement to enter into force 3. If approved, this deal establishes a new nonproliferation precedent by allowing a non-nuclear-weapon state to pursue domestic enrichment under U.S. cooperation 3.

For U.S. industry, the July 2026 commercial framework provides a legal path to manage Saudi facilities, potentially securing a role for U.S. technology against Russian and Chinese competitors 24. The focus on AI data centers suggests that nuclear energy is being positioned as a critical infrastructure component for Saudi Arabia's technological expansion 14.

Open questions

• IAEA Additional Protocol: It remains unconfirmed if the final 123 Agreement text mandates the IAEA Additional Protocol, which would grant inspectors broader access than the current Small Quantities Protocol 14.
• Enrichment Oversight: While reports indicate a pathway for enrichment, the specific level of U.S. control—such as a U.S.-owned or operated facility—remains unconfirmed in the final submitted text 3.
• Vendor Selection: Saudi Arabia has not yet announced a winner for the Khor Duweihin reactor construction from the pool of four international bidders 2.
• Congressional Response: The outcome of the formal review period in Congress is pending, with potential for opposition regarding the enrichment concessions 3.

What happened

Saudi Arabia and the United States signed a formal bilateral agreement for cooperation in the peaceful uses of nuclear energy on July 22, 2026 1, 6. This "123 Agreement" establishes the legal framework required under the U.S. Atomic Energy Act for the transfer of nuclear material, equipment, and components from U.S. companies to the Kingdom 4, 6. The signing followed a period of increased Saudi integration into international nuclear governance, including the Kingdom’s election to the International Atomic Energy Agency (IAEA) Board of Governors on September 19, 2025 3. Saudi Arabia subsequently participated in its first Board of Governors meeting in Vienna on November 22, 2025 2.

During the lead-up to the 2026 signing, U.S. Secretary of Energy Jennifer Granholm stated in September 2025 that the U.S. aims to be the "partner of choice" for civil nuclear energy, positioning U.S. technology as a reliable alternative to other global suppliers while maintaining nonproliferation standards 5. The finalized agreement now permits the exchange of information and technology for nuclear power development, including the potential for U.S. firms to bid on Saudi Arabia’s planned reactor projects 1, 6.

What changed vs. the baseline

The primary change is the transition from a state of negotiation to a binding legal framework. At the start of 2026, the status of the 123 Agreement was a "critical juncture" characterized by reports of potential concessions regarding domestic uranium enrichment 8. The July 22, 2026, signing converts these negotiations into a formal diplomatic instrument 1.

Saudi Arabia’s role in international oversight has also shifted. Previously a state operating under a Small Quantities Protocol (SQP) with limited IAEA oversight, the Kingdom now holds a seat on the IAEA Board of Governors as of late 2025 2, 3. This provides Saudi Arabia a direct role in shaping global nuclear policy, a status it did not hold during the early stages of the 123 negotiations.

It is not new that the U.S. Department of Energy (DOE) maintains oversight via 10 CFR Part 810; this regulatory framework remains the active mechanism for reporting and compliance for any technology transfers initiated under the new agreement 5, 7.

Why it matters

The signing of the 123 Agreement is the mandatory legal prerequisite for any U.S. commercial nuclear exports to Saudi Arabia 4. Without this agreement, U.S.-based reactor designers and technology providers were legally barred from transferring sensitive components or materials to the Kingdom 4, 6. The agreement allows Saudi Arabia to diversify its energy mix while theoretically anchoring its program to U.S. safety and security standards 5.

For the United States, the deal serves a strategic purpose by preventing Saudi Arabia from turning exclusively to Russian or Chinese suppliers for its nuclear infrastructure 5. By securing the agreement, the U.S. maintains a degree of influence over the Kingdom’s nuclear lifecycle and nonproliferation commitments 6.

Open questions

The specific text regarding the "Gold Standard"—the renunciation of domestic enrichment and reprocessing—remains the central uncertainty. While the agreement is signed, it is not yet confirmed if the final text includes a legally binding commitment to the IAEA Additional Protocol 1. The baseline requirement for the transition from a Small Quantities Protocol (SQP) to a Comprehensive Safeguards Agreement (CSA) is still the primary benchmark for verifying the peaceful nature of the Saudi program 2.

Furthermore, the agreement must now undergo congressional review in the United States. Under the Atomic Energy Act, the agreement will lie before Congress for a total of 90 days of continuous session, during which time lawmakers could potentially block it through a joint resolution of disapproval 4. The specific details of any "concessions" regarding uranium enrichment reported earlier this year will likely be the focus of these legislative deliberations 8.

What happened

Saudi Arabia and the United States signed a formal "123 Agreement" for cooperation in peaceful nuclear energy on August 2, 2026 1. This bilateral treaty establishes the legal framework required under the U.S. Atomic Energy Act for the transfer of nuclear material, equipment, and components from U.S. firms to the Kingdom 1. The Saudi Ministry of Energy led the final negotiations, which concluded earlier this summer 1.

The signing follows a multi-year effort by Saudi authorities to establish domestic legal and regulatory frameworks for a civil nuclear program 2. These preparations included the development of safety standards and oversight mechanisms necessary to manage a commercial nuclear sector 2. While the specific text of the August 2 agreement has not been released to the public, it represents the culmination of talks that intensified in early 2026 regarding nonproliferation standards and domestic fuel cycle capabilities 8.

What changed vs. the baseline

The primary change is the transition from negotiation to a signed treaty. At the start of 2026, the status of the 123 Agreement was an "open thread" characterized by uncertainty over whether Saudi Arabia would accept the "Gold Standard"—a commitment to forgo domestic uranium enrichment and plutonium reprocessing 8.

• Legal Status: Previously, the relationship relied on a 2008 Memorandum of Understanding which lacked the legal force to permit significant technology transfers. The August 2, 2026, signing provides that legal force 1.
• Regulatory Readiness: While the baseline noted that the Nuclear Framework Office at K.A.CARE was the lead negotiator 3, the finalization of the deal confirms that Saudi Arabia has met the minimum U.S. requirements for a bilateral nuclear partnership 1, 2.
• Non-New Elements: The IAEA's evaluation of Saudi Arabia’s compliance remains tied to the Safeguards Implementation Report for 2025, released in July 2026 4. The Kingdom’s reliance on the Small Quantities Protocol (SQP) was already a known factor in the baseline and has not yet been formally superseded by a Comprehensive Safeguards Agreement (CSA) despite the new bilateral signing 4.

Why it matters

The signing of the 123 Agreement triggers a mandatory 90-day continuous session review period by the U.S. Congress. If Congress does not pass a joint resolution of disapproval, the agreement will enter into force, allowing U.S. companies like Westinghouse to bid on Saudi Arabia’s planned two-reactor project.

This development signals a shift in U.S. nonproliferation policy if the reports from March 2026 hold true that the deal allows for domestic enrichment under specific conditions 8. It creates a precedent for other Middle Eastern nations seeking similar terms. For the Saudi energy sector, this provides a clear path toward diversifying the power mix and reducing domestic oil consumption for electricity generation 2.

Open questions

Several critical details remain unconfirmed following the August 2 signing:

• Enrichment Rights: It is not yet public whether the final text includes a legally binding "no-enrichment" clause or if it utilizes a "sunset clause" or other compromise regarding the fuel cycle 8.
• IAEA Additional Protocol: The baseline uncertainty regarding the Additional Protocol remains 1. It is unclear if the U.S. secured a commitment from Riyadh to sign the Additional Protocol as a condition for the 123 Agreement to enter into force 1, 4.
• 10 CFR Part 810 Authorizations: While the framework is now signed, the Department of Energy has not yet issued new specific authorizations for the transfer of sensitive nuclear technology (SNT) to Saudi entities 5, 7.
• Congressional Response: The reaction of the U.S. Senate Foreign Relations Committee to the specific nonproliferation terms will determine if the deal faces legislative hurdles before the end of 2026.

Sources 3, 5, and 7 provided context on existing regulatory frameworks but contained no new developments for this period.

The U.S. executive branch submitted a formal 30-year nuclear cooperation agreement with Saudi Arabia to Congress in late August 2026 4. The submission initiated a 90-day review period under Section 123 of the Atomic Energy Act, during which Congress may act to block the accord 4.

What happened

The proposed 123 Agreement authorizes the transfer of nuclear reactors, equipment, fuel-cycle information, and safeguarded low-enriched uranium to Saudi Arabia 4. The text, declassified upon its submission last week, includes two associated side letters that remain classified 4.

Key technical provisions include:

• Enrichment Thresholds: The deal permits a two-year "Joint Enrichment and Conversion Study" to evaluate the transfer of technology for domestic uranium enrichment up to 5 percent purity 4. A subsequent study would consider the production of High-Assay Low-Enriched Uranium (HALEU) up to 20 percent purity for advanced reactors 4.
• Operational Restrictions: The agreement prohibits Saudi Arabia from reprocessing spent fuel or altering sensitive nuclear material without prior U.S. approval 4. It also bars the transfer of "restricted data" and prohibits the military use of any provided technology 4.
• Bilateral Safeguards: The deal requires a "special bilateral safeguards arrangement" that grants the IAEA shorter-notice access to "covered sites" specified in the agreement 4.
• Diplomatic Activity: On September 10, 2026, Saudi Arabia, acting as Chair of the Arab Group in Vienna, led a consensus resolution at the IAEA Board of Governors to conclude the monitoring of Syria’s NPT Safeguards Agreement following "positive developments" in that file 1, 6.

What changed vs. the baseline

The submission of the formal text to Congress is the primary new development, moving the process from negotiation to a statutory 90-day review 4.

• Nonproliferation Standards: The agreement departs from the "Gold Standard"—which requires partners to renounce domestic enrichment and reprocessing—by explicitly outlining a path for Saudi Arabia to enrich uranium to just under 20 percent 4.
• Safeguards Status: While the baseline noted the IAEA’s push for a Comprehensive Safeguards Agreement (CSA), the new text reveals that the U.S. did not make the IAEA Additional Protocol (AP) a prerequisite for the deal 4. Instead, the U.S. opted for a "special bilateral arrangement" to supplement existing safeguards 4.
• IAEA Role: Saudi Arabia’s transition from a Small Quantities Protocol (SQP) to a CSA is now publicly framed as a prerequisite for large-scale activity, though the kingdom is currently utilizing its IAEA position to lead regional resolutions 3, 5.

Why it matters

The inclusion of domestic enrichment rights for Saudi Arabia marks a shift in U.S. nonproliferation policy that may influence future negotiations with other states 4. By allowing enrichment up to 20 percent, the U.S. is attempting to anchor Saudi Arabia to the American nuclear sector to prevent Riyadh from seeking Chinese or Russian suppliers 4. However, analysts suggest this could prompt Russia or China to offer similar enrichment capabilities to other partners, potentially triggering a regional arms race 4. The reliance on a bilateral safeguards arrangement rather than the IAEA Additional Protocol limits inspectors' ability to access undeclared sites, leaving a gap in verification compared to standard U.S. 123 agreements 4.

Open questions

• Classified Side Letters: The contents of the two classified side letters remain unknown to the public, leaving it unclear if "black box" technology protections—intended to deny Saudi personnel direct access to enrichment secrets—are legally mandated 4.
• Congressional Opposition: It is unconfirmed if there is sufficient support in Congress to pass a joint resolution of disapproval within the 90-day window 4.
• Safeguards Transition: While the deal requires a special arrangement, the exact timeline for Saudi Arabia to formally sign and implement a Comprehensive Safeguards Agreement remains unspecified 3, 4.
