FY 2026 NDAA Section 8366 Establishes Nuclear Export Working Group, Builds Bureaucratic Infrastructure for U.S.-Saudi Civil Nuclear Agreement

On December 18, 2025, President Trump signed into law the Fiscal Year 2026 National Defense Authorization Act, which included Section 8366 — the International Nuclear Energy Act of 2025. Section 8366 establishes a Nuclear Export Working Group, directs the Secretary of Energy to promote U.S. reactors, fuel, equipment, and services abroad, and requires the Secretary of State (in consultation with the Secretary of Energy) to deliver Congress a strategy for promoting U.S. nuclear exports in countries “where Rosatom is present.” The section authorizes up to $15.5 million per year (FY 2026-2030) for technical assistance to “embarking nuclear nations” and makes no specific reference to Saudi Arabia in the statutory text, but its structural beneficiary is the U.S.-Saudi civil nuclear cooperation framework that was finalized the preceding month.

What Section 8366 Does

• Establishes a Nuclear Export Working Group charged with developing a 10-year civil nuclear trade strategy targeting exports of light-water and non-light-water reactors, associated equipment, fuel, and materials
• Directs the Secretary of Energy to empower U.S. nuclear companies to negotiate agreements with foreign countries, bypassing some of the traditional State-Department-led 123-agreement process
• Creates a technical assistance and grants program for embarking nuclear nations (up to $15.5M/year, FY 2026-2030) covering regulatory-body capacity, legal frameworks, and workforce training
• Mandates a presidential strategy to Congress specifically on countries where Rosatom is present, with the stated goal of ending foreign reliance on the Russian nuclear energy sector

The section’s statutory frame is neutral — it does not name Saudi Arabia, UAE, Egypt, Turkey, or any other specific country as a target market. The frame’s operative content is the Rosatom-footprint language, which in the Gulf context translates principally to Saudi Arabia and Egypt (both of which have had Rosatom tenders in the 2018-2024 period).

The U.S.-Saudi Civil Nuclear Context

During Saudi Crown Prince Mohammed bin Salman’s November 2025 visit to Washington, the United States and Saudi Arabia signed a Joint Declaration on the Completion of Negotiations on Civil Nuclear Energy Cooperation. Per Arms Control Association reporting (March 2026), the resulting agreement:

• Does not require Saudi Arabia to sign the IAEA Additional Protocol that the United States customarily requires of civil nuclear partners
• May permit some form of uranium enrichment on Saudi soil — a significant departure from the “Gold Standard” U.S. civil nuclear policy precedent
• Is structured so the administration can submit the resulting 123 agreement to Congress as early as February 22, 2026, after which Congress has 90 continuous-session days to reject the agreement by joint resolution — otherwise it becomes law automatically

Section 8366 builds the bureaucratic machinery — Working Group, strategy documents, funding streams, empowerment of U.S. vendor-side negotiation — that operationalizes precisely this kind of non-standard agreement. The Working Group’s ability to direct technical assistance funding to “embarking nuclear nations” also positions U.S. vendors (Westinghouse, Holtec, X-energy, NuScale, TerraPower) to capture early-stage consulting and design-phase fees in Saudi Arabia and adjacent markets.

Why This Event Matters

The procedural pattern is the point. A standalone bill authorizing the Nuclear Export Working Group, the grant authority, and the Rosatom-footprint strategy would have drawn scrutiny from the nonproliferation caucus (Markey, Castro, Merkley, Van Hollen) and the arms-control community. As a bundled provision in a $901 billion must-pass defense authorization, Section 8366 passed without a recorded standalone vote. Combined with the February 2026 deadline for the administration to submit the U.S.-Saudi 123 agreement, the FY 2026 NDAA structurally enables the Saudi civil nuclear cooperation pipeline to proceed on an abbreviated legislative timeline.

The Saudi civil nuclear architecture is also relevant to documented Trump-family commercial architecture:

• Trump Organization + Dar Global $10B Saudi slate (announced January 11, 2026) — Dar Global is majority-owned by Dar Al Arkan, which has Saudi Public Investment Fund adjacency
• Affinity Partners $6.16B AUM with QIA + Lunate anchor investment (Kushner) — Saudi PIF is Affinity’s largest LP, per Kushner’s 2018-2024 fundraising history
• Trump Tower Jeddah ($1B announcement, May 2025) — Trump Organization licensing deal

Each of these commercial positions benefits from deepening U.S.-Saudi strategic ties. Section 8366 is one instrument of that deepening.

Broader Policy Implications

• Nonproliferation regime: The “Gold Standard” (no-enrichment, no-reprocessing) civil nuclear model has been a U.S. position since 2009. A non-Gold-Standard Saudi agreement sets a precedent other Gulf states (UAE, Qatar, Bahrain) and larger non-proliferation-community nations (Egypt, Turkey) may demand in their own 123 agreements.
• Rosatom displacement strategy: The Rosatom-footprint framing advances a legitimate U.S. industrial-policy objective (reducing Russian nuclear sector revenue) while simultaneously providing cover for Saudi-specific concessions.
• Congressional review truncation: The 90-continuous-session-day review window with automatic-enactment default is a weak check on an agreement that materially loosens nonproliferation standards. Section 8366’s bureaucratic infrastructure makes rejection politically harder because the implementing machinery is already statutorily authorized and partially funded.

Research Gaps

• Section 8366 conference-committee sponsorship — which members negotiated the provision into conference text
• Whether Section 8366’s working group charter has been published and members named as of April 2026
• Full text of the U.S.-Saudi Joint Declaration on Civil Nuclear Energy Cooperation
• Whether Dar Global, Trump Organization, Affinity Partners, or other Trump-family vehicles have specific exposure to Saudi civil nuclear procurement or site preparation contracts
• FY 2026 NDAA floor amendments targeting Section 8366 that were rejected (if any)
• Arms Control Association’s identification of the specific members of the working group charter discussions
