When Energy Secretary Chris Wright and Saudi Energy Minister Prince Abdulaziz bin Salman signed the Section 123 agreement in Riyadh on Wednesday, they did more than greenlight a commercial nuclear partnership. They rewrote the rules of engagement for civilian nuclear cooperation in the Middle East, granting the kingdom a conditional pathway to enrich uranium on its own soil — a capability the United States explicitly denied its closest regional partner, the United Arab Emirates, seventeen years ago.
What Happened
The agreement, negotiated under the Atomic Energy Act’s Section 123 framework, permits Saudi Arabia to pursue domestic uranium enrichment and fuel reprocessing capabilities subject to future negotiations over specific facilities and safeguards. In exchange, Riyadh has committed to contracting U.S. firms — notably Westinghouse and potentially GE Hitachi — for the kingdom’s planned reactor fleet, which Crown Prince Mohammed bin Salman has said could total sixteen large reactors over the next two decades. The deal also requires Saudi acceptance of the Additional Protocol to its IAEA safeguards agreement, granting inspectors expanded access rights.
Critically, the text does not include a legally binding renunciation of enrichment — the so-called “gold standard” provision embedded in the 2009 UAE agreement. Instead, it establishes a “pathway” mechanism: enrichment rights would be triggered by a future bilateral arrangement, contingent on Saudi adherence to enhanced transparency measures and a yet-to-be-defined “credible” peaceful-use justification. Administration officials described this as a “phased approach” that preserves U.S. leverage while accommodating Saudi sovereignty claims.
Why It Matters
The proliferation implications are immediate and structural. By legitimizing a Saudi enrichment pathway, the administration has effectively nullified the gold standard as a normative benchmark for the region. Turkey, Egypt, and Jordan — all pursuing civilian nuclear programs with varying degrees of maturity — will now cite the Saudi precedent to demand equivalent treatment. South Korea’s nuclear export ambitions, already complicated by its own enrichment aspirations, gain new diplomatic cover. The Nonproliferation Treaty’s Article IV guarantee of “inalienable rights” to peaceful nuclear technology has never been tested quite this way: a U.S. partner actively seeking enrichment while facing unresolved questions about past undeclared nuclear activities, including the 2020 revelation of an undeclared uranium ore concentration facility near Al-Ula.
Commercially, the deal is a lifeline for a U.S. nuclear industry that has not broken ground on a new domestic reactor since Vogtle Unit 3 reached criticality in 2023. Westinghouse, now majority-owned by Brookfield Renewable Partners after its 2018 bankruptcy emergence, stands to secure a multi-billion-dollar reactor supply contract — potentially the largest single export order in the company’s history. But the enrichment pathway introduces a strategic contradiction: every centrifuge cascade Riyadh builds domestically reduces its long-term dependence on U.S. fuel services, the very revenue stream that sustains the commercial rationale for the partnership.
On Capitol Hill, the agreement faces a 90-day congressional review period under the Atomic Energy Act. Senate Foreign Relations Committee Chairman Jim Risch (R-Idaho) and Ranking Member Jeanne Shaheen (D-N.H.) have already signaled bipartisan skepticism. In a joint statement Thursday, they warned that “any pathway to enrichment must be accompanied by ironclad, verifiable constraints — not aspirational benchmarks.” The House Foreign Affairs Committee has scheduled a markup for next week on a resolution of disapproval, though passage would require a veto-proof two-thirds majority in both chambers — a high bar given the administration’s framing of the deal as a counterweight to Chinese and Russian nuclear influence in the Gulf.
Historical Context
The 2009 UAE agreement, negotiated by the Bush administration and finalized under Obama, established the gold standard precisely because Abu Dhabi accepted it voluntarily — a sovereign choice to forgo enrichment in exchange for expedited cooperation and international credibility. That precedent held for fifteen years across three administrations. The Trump administration’s reversal reflects a broader strategic recalibration: the belief that denying enrichment to partners simply drives them toward Rosatom or CNNC, the Russian and Chinese state nuclear champions who impose no such conditions. As one senior National Security Council official put it on background: “We can set the rules from inside the tent, or watch from outside while Moscow and Beijing write them.”
There is also the Iran dimension. The 2015 JCPOA permitted Tehran limited enrichment under strict caps; its collapse after the 2018 U.S. withdrawal left a vacuum that Riyadh has repeatedly cited to justify its own “right” to enrich. Crown Prince Mohammed told The Atlantic in 2022: “If Iran enriches, we enrich.” Wednesday’s agreement operationalizes that logic without resolving the underlying security dilemma. IAEA Director General Rafael Grossi, briefing reporters in Vienna Thursday, noted that “any expansion of enrichment capacity in the region requires proportionate verification measures” — a diplomatic signal that the agency views the Saudi pathway as a safeguards challenge, not a settled matter.
What to Watch
Three developments will determine whether this agreement becomes a model or a cautionary tale. First, the negotiation of the “enrichment arrangement” referenced in the 123 text — expected to begin within six months — will reveal whether the administration insists on multinational fuel bank participation, centrifuge design limitations, or a hard cap on separative work units. Second, Saudi ratification of the Additional Protocol, which Riyadh has signed but not yet brought into force, will test the kingdom’s transparency commitment. Third, the congressional review process may produce binding conditions: the 2024 National Defense Authorization Act included a provision requiring certification that any Saudi enrichment pathway includes “effective physical protection against diversion” — language that could force tighter technical constraints than the executive branch prefers.
Watch also for the reaction in Seoul and Ankara. South Korea’s Yoon administration has sought U.S. consent for pyroprocessing research — a reprocessing-adjacent technology — since 2021. Turkey’s Akkuyu plant, built by Rosatom, operates under a build-own-operate model that sidesteps 123 requirements entirely. If the Saudi deal normalizes enrichment pathways for U.S. partners, the nonproliferation regime’s remaining coherence faces a stress test it may not survive.
Key Takeaway
The Saudi 123 agreement represents a calculated gamble: that commercial leverage and strategic alignment can substitute for the nonproliferation guardrails the United States once insisted were non-negotiable. By trading the gold standard for a foothold in Riyadh’s reactor market, the Trump administration has bet that it can manage proliferation risks through ongoing diplomatic engagement rather than upfront legal prohibition. History suggests such bets rarely pay off in a region where nuclear latency has become a currency of power — and where every concession to one partner becomes a precedent for the next.
