This month’s issue of Nuclear News focuses on supply and demand. The “supply” part of the story highlights nuclear’s continued success in providing electricity to the grid more than 90 percent of the time, while the “demand” part explores the seemingly insatiable appetite of hyperscale data centers for steady, carbon-free energy.

Technically, we are in the second year of our AI epiphany, the collective realization that Big Tech’s energy demands are so large that they cannot be met without a historic build-out of new generation capacity. Yet the enormity of it all still seems hard to grasp.

or the better part of two decades, U.S. electricity demand has been flat. Sure, we’ve seen annual fluctuations that correlate with weather patterns and the overall domestic economic performance, but the gigawatt-hours of electricity America consumed in 2021 are almost identical to our 2007 numbers.

Gov. Katie Hobbs put the brakes on legislation that would have eliminated some of Arizona’s regulations and oversight of small modular reactors, technology that is largely under consideration by data centers and heavy industrial power users.

The Federal Energy Regulatory Commission has doubled down on its rejection of an interconnection service agreement (ISA) between Amazon Web Services and Talen Energy in Pennsylvania.

The Department of Energy’s Office of Nuclear Energy has posted a list of the advantages and challenges of using nuclear energy to power AI data centers, which some estimates suggest could consume as much as 12 percent of U.S. energy production by 2028. The DOE also posted a brief video on its YouTube channel to accompany the list.

Melbye

During an interview for Kitco News at the 2025 Prospectors & Developers Association of Canada (PDAC) Convention, held in Toronto in early March, the chief executive of British Columbia–based Uranium Royalty Corp. noted, “I’ve never seen a better narrative around nuclear power [and] uranium.”

CEO Scott Melbye, who is also executive vice president of Texas-based Uranium Energy Corp. and has 41 years of experience in the uranium sector, added that nuclear energy has gone from stagnation or decline to a point where it may double by 2040.

A pair of bills working their way through the Iowa statehouse aim to promote nuclear energy projects in the state—in part by changing how the plants would be regulated and funded.

TerraPower has continued to make aggressive progress in several areas for its Natrium Reactor Demonstration Project since the beginning of the year. Natrium is an advanced 345-MWe reactor that has liquid sodium as a coolant, improved fuel utilization, enhanced safety features, and an integrated energy storage system, allowing for a brief power output boost to 500 MWe if needed for grid resiliency. The company broke ground for its first Natrium plant in 2024 near a retiring coal facility in Kemmerer, Wyo.

Uranium futures closed out February at about $65.55 per pound, according to online analysist firm Trading Economics. Futures prices have been below $66 per pound since mid-February.

The International Energy Agency has published a new report examining opportunities for the nuclear power industry to address concerns related to energy security and climate change. The Path to a New Era for Nuclear Energy explores areas of policy, innovation, construction, and financing with an emphasis on investment-related issues regarding small modular reactors.

The IEA report describes encouraging developments taking place in the nuclear energy industry, such as increasing investment, technology advances, and supportive policies in many countries. But it also notes that certain key challenges need to be overcome if nuclear energy is to meet the needs of rising electricity demand, including demands from artificial intelligence and data centers. In addition to examining the present global status of nuclear power, the report evaluates the long-term outlook, quantifying expected capacity and investment through 2050.

As demand for artificial intelligence and data centers grows, President Biden issued an executive order yesterday aimed to ensure clean-energy power supply for the technology.

Advanced nuclear company Oklo and data center developer Switch closed out 2024 by announcing a new partnership to deploy 12 GW of advanced nuclear power under a master power agreement.

Constellation is launching a pilot program that allows its Washington, D.C., customers to purchase 100 percent nuclear energy for their homes.

A new complaint filed by Constellation asks the Federal Energy Regulatory Commission to order the PJM Interconnection to provide rules for co-located generation to serve large facilities, such as data centers.

Oklo Inc. announced yesterday that it has partnered with “two major data center providers” under letters of intent (LOIs) to deliver up to 750 MW of power from multiple 15 MW or 50 MW Oklo microreactors at data centers in “select” undisclosed U.S. markets.

As a primer to the American Nuclear Society Winter Conference and Expo, ANS Executive Director/Chief Executive Craig Piercy hosted a panel discussion titled “The State of Nuclear,” sponsored by the ANS Trustees of Nuclear. The October 29 discussion, the first in a two-part series, featured five thought leaders from the nuclear community as they reviewed the current state of nuclear power. The second panel will take place during the ANS Winter Conference in Orlando, Fla., on November 18.

The discovery of a rare species of bee by environmental regulators has blocked the plans of tech conglomerate Meta to build an artificial intelligence data center powered by nuclear energy—at least temporarily. Numerous media outlets, including Popular Science, have reported that the unnamed species of bee was detected by regulators who were surveying the land designated for the new data center—land that is located next to an unnamed nuclear power plant from which Meta had planned to obtain electricity.

The Federal Energy Regulatory Commission has denied plans for Talen Energy to supply additional on-site power to an Amazon Web Services’ data center campus from the neighboring Susquehanna nuclear plant in Pennsylvania.

Tech giant Amazon announced Wednesday new partnerships with Dominion Energy and X-energy to develop and deploy 5 gigawatts of nuclear energy to power needs across the country over the next 15 years.

Washington, D.C. — Craig Piercy, CEO of the American Nuclear Society (ANS), issued the following statement:

"The American Nuclear Society applauds the announced partnerships between Google and Kairos Power and by Amazon and X-energy. Together, these deals will add at least 820 megawatts of zero carbon electricity to the U.S. energy supply. This is a major step toward securing the commercial deployment of advanced nuclear technologies that will make the world a cleaner and more prosperous place."

A white paper produced by Schneider Electric makes the case for using small modular reactors to meet the energy challenges of the data center sector. “Small Modular Nuclear Reactors Suitability for Data Centers,” by Marcin Wegrzyn and Steven Carlini, discusses the potential SMRs offer for supplying reliable, low-carbon energy to data centers, along with enhanced operational safety and improved energy resiliency, compared with renewable alternatives. However, to better evaluate SMR suitability for the continued technological advancement of data centers, an improved regulatory landscape, and ongoing international cooperation are necessary.
