Saudi Arabia’s civil nuclear programme: strategic milestone, legal framework, and global opportunities for contractors

Saudi Arabia’s civil nuclear ambitions have reached a historic turning point. The signing of the 30-year US-Saudi Section 123 Agreement in July 2026 marks a step-change in the Kingdom’s relationship with the global nuclear community and further supports the Kingdom as a major player in the Middle East’s energy transition.

As Saudi accelerates its drive to diversify its energy mix and reduce reliance on hydrocarbons, the nuclear sector has the potential to become a key cornerstone of Vision 2030. This Article assesses the latest developments, international context, and actionable opportunities for civil contractors - drawing on both recent news and the Kingdom’s evolving legal and nuclear frameworks.
 

Latest News: US-Saudi 123 Agreement and Its Implications

The Core Agreement

On 22 July 2026, US Energy Secretary Chris Wright and Saudi Energy Minister Prince Abdulaziz bin Salman signed a landmark civil nuclear co-operation agreement. This 30-year pact establishes the legal foundation for American companies to participate in building Saudi Arabia’s civilian nuclear infrastructure. It includes a joint two-year feasibility study for a potential US-built uranium enrichment facility, although current terms prohibit domestic enrichment and favour an import-based fuel model.
 

Diplomatic Uncertainty

Despite the historic signing, the agreement faces immediate diplomatic challenges. President Donald Trump has publicly tied the deal’s implementation to Saudi normalisation of relations with Israel under the Abraham Accords - a linkage Saudi officials reject. This political contingency introduces uncertainty into the programme’s existence, timeline and scope.
 

Safeguards and Non-Proliferation Concerns

The agreement relies on bespoke bilateral safeguards rather than the International Atomic Energy Agency’s (IAEA) Additional Protocol. Saudi Arabia has to date resisted signing the Additional Protocol. Congressional review in the US is underway, with bipartisan concern over the absence of a permanent Saudi commitment to forgo domestic enrichment. The outcome will shape the operational environment for all stakeholders.
 

Strategic Context: Vision 2030 and Global Supply Chain Dynamics

National Project for Atomic Energy (NPAE)

Saudi Arabia’s civil nuclear strategy is integrated into Vision 2030. The National Project for Atomic Energy (NPAE) aims to introduce nuclear power to meet soaring domestic grid demand and significant water desalination needs. By replacing domestic hydrocarbon burning with baseline nuclear power, the Kingdom preserves crude oil for high-value exports.
 

Commercialisation and Full Fuel Cycle Ambitions

The state-managed Nuclear Holding Company (NHC) coordinates international purchasing tenders, asset capitalisation, and joint ventures. Saudi Arabia plans to manage the entire nuclear fuel cycle domestically, ideally, including uranium exploration, yellowcake production, and low-enriched uranium fuel manufacturing, potentially for both domestic use and export.
 

Legal and Regulatory Framework: Liability, Treaties, and Complianc June 202e

Domestic Nuclear Liability Laws

Saudi Arabia has established a modern legal framework overseen by the Nuclear and Radiological Regulatory Commission (NRRC). The Law of Civil Liability for Nuclear Damage features:

• Strict Vendor Channelling: Vendors and contractors are legally isolated from third-party lawsuits; liability is channelled exclusively to the operator.

• Absolute Operator Liability: Victims do not need to prove fault; operators are held absolutely liable by default.

• Mandatory Insurance Caps: Operators must maintain robust financial security or insurance aligned with global standards.
   

International Nuclear Liability Conventions

Saudi has been progressive in integrating international nuclear liability & transparency treaties:

 
Proliferation and Safeguards Debate

The July 2026 US-Saudi 123 Agreement diverges from the UAE’s “Gold Standard.” While it allows a joint study on indigenous enrichment, current terms prohibit domestic enrichment. Saudi Arabia refuses to sign the IAEA’s Additional Protocol, instead opting for bilateral safeguards monitored by US authorities.
 

Opportunities for Civil Contractors

1. Infrastructure Development and Construction

Saudi Arabia’s nuclear build-out encompasses reactor construction and supporting infrastructure—transport, water, waste management, and grid integration. US firms are poised for high-level contracts, but actual construction will rely on South Korean, European, and other international suppliers.

Opportunities include:

• EPC contracts for nuclear power plants and ancillary facilities

• Civil works for site preparation, access roads, and utilities

• Specialised construction for nuclear-grade containment, security, and waste storage
   

2. Supply Chain Participation

Nuclear projects require a vast, multi-tiered supply chain. Contractors with expertise in nuclear standards, quality assurance, and regulatory compliance will find opportunities in:

• Fabrication and supply of nuclear-grade materials and components

• Safety and security systems provision

• Logistics and project management services
   

3. Localisation and Joint Ventures

Vision 2030 emphasises localisation and technology transfer. International contractors can enhance competitiveness by forming joint ventures with Saudi firms, investing in local manufacturing, and training the workforce.
 

4. Regulatory and Compliance Advisory

Contractors will require sophisticated legal, regulatory, and risk management advice. As an international law firm with nuclear sector expertise and a presence in both London and Riyadh, Stephenson Harwood is uniquely positioned to provide this support.
 

Potential Technologies Under Consideration

Saudi Arabia’s plans include large-scale Generation III+ baseload stations, integrated fuel cycle operations, and potentially advanced Small Modular Reactors (SMRs):

SMRs are under consideration for localised desalination and decentralised grids. Saudi Arabia’s first research reactor, built by Argentina’s INVAP, is complete and awaits fuelling.
 

The Role of International Law Firms: Adding Value Across the Project Lifecycle

Navigating Regulatory Complexity

Law firms have a vital role to play, advising clients on compliance with US, Saudi, and international nuclear regulations, structuring contracts to manage export control and non-proliferation risks, and navigating bilateral safeguards.
  

Structuring Consortia and Joint Ventures

With legal advisors playing a critical role in drafting and negotiating joint venture agreements, advising on local content and technology transfer, and managing intellectual property and dispute resolution. As major infrastructure projects, nuclear new build programme typically involve complex financing and risk profiles. Law firms can assist with project finance arrangements, government guarantees, insurance, and contractual risk allocation.
 

Dispute Resolution and Crisis Management

Disputes are inevitable given the high stakes and geopolitical sensitivities. At Stephenson Harwood, we have considerable expertise in international arbitration, with construction/engineering lawyers on the ground, in Saudi, Singapore and London, who can help clients navigate challenges and protect their interests.
