The United States and Saudi Arabia signed a peaceful nuclear cooperation agreement on July 22, 2026, establishing a 30-year civilian nuclear partnership in which U.S. companies will build Saudi Arabia's nuclear power program. President Trump approved the deal and will seek Congressional approval for the pact, which could permit uranium enrichment on Saudi soil. The U.S. Department of Energy published the official announcement, capping a negotiation track that produced a Joint Declaration on the Completion of Negotiations on Civil Nuclear Cooperation signed by the U.S. Energy Secretary and Saudi Arabia's Energy Minister.

The agreement frames a multi-billion-dollar, decades-long partnership. U.S. companies are positioned to construct and supply Saudi Arabia's civil nuclear infrastructure, covering areas the two governments previously outlined for cooperation: nuclear safety, security, and nonproliferation programs. The National Nuclear Security Administration participated in the negotiation process. A separate Memorandum of Understanding between the two governments concerning cooperation in nuclear energy and other energy sectors had been established earlier in the bilateral track.

The deal's most consequential provisions concern the fuel cycle. The agreement provides a legal pathway for cooperation on the nuclear fuel cycle and could allow uranium enrichment inside Saudi Arabia, while aiming to prevent enrichment to weapons-grade levels. It includes a waiver for inspections. The pact omits a protocol for IAEA oversight, as detailed by Reuters. The agreement's nonproliferation provisions, in other words, rest on bilateral terms rather than the comprehensive safeguards architecture the IAEA typically applies under Additional Protocols.

The enrichment question has been the central sticking point in U.S.-Saudi nuclear discussions for years. Saudi Arabia has insisted on domestic enrichment as a matter of sovereign right, while U.S. legislators and nonproliferation advocates have sought to restrict any 123 Agreement to a gold-standard prohibition on enrichment and reprocessing. The fact that this deal permits a pathway to enrichment — however constrained — marks a departure from the terms the United States has historically demanded from partners in the region. The omission of an IAEA oversight protocol compounds the concern, placing verification in a bilateral framework whose enforcement mechanisms remain unclear from the public record.

The broader context here is the regional nuclear landscape. The agreement arrives after years in which Saudi Arabia's nuclear ambitions have been scrutinized against the backdrop of Iran's enrichment program. By granting Riyadh a legal route to enrichment without mandatory IAEA oversight, the deal could complicate the already fragile nonproliferation consensus in the region. Congressional review, which the administration will formally trigger, provides the primary remaining checkpoint. Under the Atomic Energy Act, Congress has a fixed period to review a 123 Agreement and can reject it by joint resolution. Whether opponents can assemble the votes to do so will determine whether the agreement proceeds on its current terms.

The agreement's nonproliferation language, which aims to prevent weapons-grade enrichment, leaves open the question of how that prohibition would be enforced in the absence of IAEA monitoring. Bilateral inspections waivers, depending on their scope, could limit the United States' own ability to verify compliance. The technical details of the waiver — what it covers, what it excludes, and what alternative verification mechanisms substitute — will be subject to scrutiny during the Congressional review period.

What the deal does, concretely, is open the Saudi civil nuclear market to American industry while accepting Saudi enrichment as a negotiated outcome rather than a red line. The trade-off — commercial access in exchange for a looser nonproliferation framework — is one Congress will now weigh. The stakes extend beyond the bilateral relationship: any precedent set here for enrichment tolerance and oversight arrangements will inform how other nuclear-aspirant states approach their own negotiations with suppliers.
