On January 9, tech giant Meta made waves by announcing three new agreements with Vistra, TerraPower, and Oklo. These deals aim to see Meta supporting both uprates at existing nuclear power plants and the development of new advanced reactor projects, and in total could see the company financing up to 6.6 GW of new and existing energy by 2035. These projects will support the hyperscaler’s ever-growing data center– and AI-driven energy needs.

Nuclear energy is entering a new era—and policymakers are driving that shift. Governors, energy advisors, legislators, and regulators play a critical role in shaping state policies and regulations that can support the existing nuclear fleet and can accelerate the development, demonstration, and commercial deployment of next-­generation nuclear energy.

As Nuclear News has done since 2022, we have compiled a review of the nuclear news that filled headlines and sparked conversations in the year just completed. Departing from the chronological format of years past, we open with the most impactful news of 2025: a survey of actions and orders of the Trump administration that are reshaping nuclear research, development, deployment, and commercialization. We then highlight some of the top news in nuclear restarts, new reactor testing programs, the fuel supply chain and broader fuel cycle, and more.

Thursday was a busy news day for the Nuclear Regulatory Commission, with three significant announcements.

In the span of a few hours, the NRC released the news of Ho Nieh’s promotion to chair, the reversal of the plan to sunset its aircraft impact assessment provisions, and new guidance for interagency collaboration.

New power reactors of any size can be now be sited in the state of Illinois, thanks to legislation signed by Gov. J. B. Pritzker on January 8. The Clean and Reliable Grid Affordability Act (CRGA)—which Pritzker says is designed to lower energy costs for consumers, drive the development of new energy resources in the state, and strengthen the grid—lifts the moratorium on new, large nuclear reactors that Illinois enacted in the late 1980s.

The past few years have seen a concerted effort from many U.S. states to encourage nuclear development. The momentum behind nuclear-friendly policies has grown considerably, with many states repealing moratoriums, courting nuclear developers and suppliers, and in some cases creating advisory groups and road maps to push deployment of new nuclear reactors.

As executive vice president for industry strategy at the Institute of Nuclear Power Operations, Jeff Place leads INPO’s industry-facing work, engaging directly with chief nuclear officers.

The U.S. nuclear industry is standing at its most volatile regulatory moment yet—one that will shape the trajectory and safety of the industry for decades to come. Recent judicial, legislative, and executive actions have converged to rewrite the rules governing the licensing and regulation of nuclear power reactors. Although these changes are intended to promote and accelerate the deployment of new nuclear energy technologies, the collision of multiple legal shifts—occurring simultaneously and intersecting with profound technological uncertainties—is overwhelming the Nuclear Regulatory Commission and threatening to destabilize investor and industry expectations.

In early 1951, Los Alamos scientists Edward Teller and Stanislaw Ulam devised a breakthrough that would lead to the hydrogen bomb [1]. Their design gave the United States an initial advantage in the Cold War, though comparable progress was soon achieved independently in the Soviet Union and the United Kingdom.

The U.S. House Energy and Commerce Subcommittee on Energy convened its first hearing of the year, “American Energy Dominance: Dawn of the New Nuclear Era,” on January 7, where lawmakers and industry leaders discussed how nuclear energy can help meet surging electricity demand driven by artificial intelligence, data centers, advanced manufacturing, and national security needs.
