Under the auspices of Section 5 of Executive Order 14300, Ordering the Reform of the Nuclear Regulatory Commission, the Nuclear Regulatory Commission (NRC) published on November 26, 2025 an immediately effective final rule, Streamlining Select Rules of Practice and Procedure. The NRC rescinded a “discrete number” of its rules of practice as “either inconsistent with statutory requirements or duplicative of statutory requirements and other binding regulations.”

As part of the response to four executive orders focused on expanding and accelerating the development and use of nuclear energy, the US Department of Energy and US Nuclear Regulatory Commission have signed Addendum 9 to their 2019 Memorandum of Understanding on Nuclear Energy Innovation. The October 24 addendum details how the agencies will coordinate their activities on advanced reactors and nuclear fuel technologies more efficiently to implement activities under the EOs. The addendum underscores a whole-of-government approach to demonstrating and licensing advanced reactors and speeding up the transition from research to commercial deployment.

In connection with President Donald Trump’s recent state visit to the United Kingdom, the United States and the United Kingdom unveiled a slate of new and expanded agreements designed to accelerate cooperation in nuclear energy, advanced technologies, and professional engagement. These deals are intended to be a significant step forward in our longstanding transatlantic alliance, aligning regulatory efforts, advancing innovation, and reinforcing the shared goal of a secure, clean energy future.

Throughout 2025, several US states have taken steps to facilitate development of new nuclear reactors. Complementing several recent executive orders of the US administration in support of nuclear energy, including plans to bring new test reactors online by summer 2026 as part of the Reactor Pilot Program, states such as Illinois, Nebraska, Tennessee, Texas, and Virginia have also signaled support for nuclear energy through legislation, grants, and utility initiatives.

The US Nuclear Regulatory Commission (NRC) recently issued a direct final rule extending the duration of design certifications (DCs) for nuclear reactors from 15 to 40 years. The rule will automatically go into effect on September 15, 2025, unless the NRC receives significant adverse comments from the public.

The US Nuclear Regulatory Commission (NRC) staff recently submitted recommendations and planned actions to the Commission aimed at enhancing elements of the Reactor Oversight Process (ROP) consistent with the Accelerating Deployment of Versatile, Advanced Nuclear for Clean Energy Act of 2024 (ADVANCE Act). These efforts would also in part be responsive to recently issued Executive Order 14300, “Ordering the Reform of the Nuclear Regulatory Commission.”

The United States and Thailand signed an agreement on January 14, 2025, which outlines peaceful nuclear cooperation between the two countries. The agreement is authorized by Section 123 of the Atomic Energy Act of 1954, as amended (42 USC § 2153) (AEA), and is known as a “123 Agreement.” That same day, former President Biden transmitted that 123 Agreement and a Nuclear Proliferation Assessment Statement (NPAS) to Congress for their review. Congress has 90 days of being in session to either disapprove or passively allow the Agreement to take effect.

A recent decision by the US Court of Appeals for the Federal Circuit reinstated claims seeking indemnification under the Price-Anderson Act. In reversing a decision by the US Court of Federal Claims, the Federal Circuit affirmed the broad scope of the Price-Anderson Act’s contractual indemnity provision. In particular, the Federal Circuit found that the Price-Anderson Act requires the government to indemnify more entities than just those that directly contracted with the government. Instead, the statutory language contemplates indemnity to “any other person who may be liable for public liability.”

The National Environmental Policy Act of 1969 (NEPA) requires federal agencies, including the Nuclear Regulatory Commission (NRC), to evaluate the potential environmental impacts of their proposed actions. That statute also established the White House Council on Environmental Quality (CEQ), which was tasked with issuing NEPA implementation guidelines.

The demand for energy is anticipated to rise significantly due to the increased deployment of artificial intelligence (AI) technologies, which are highly energy intensive. As we discussed in a recent thought leadership piece, there is a strong intersection between nuclear power and AI. Not only is nuclear power generation well-positioned to address the growing need for powering AI, but the nuclear power industry and its primary regulator, the US Nuclear Regulatory Commission (NRC) are looking to leverage AI to increase efficiency and strategic decision-making.
