The Nuclear Regulatory Commission is gearing up to tackle an influx of licensing requests and oversight of advanced nuclear reactor technology, especially small modular reactors.

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.

The preservation of records, knowledge, and memory is recognized as an important component of nuclear waste management, preventing future generations from unnecessary interference with a waste repository and supporting future societies to make informed decisions about such sites.

A new report from the Atlantic Council Global Energy Center follows up on its 2024 workshops with recommendations for deploying advanced nuclear energy in the Appalachian area to spur economic development.

Inspired by a history of similar testing endeavors and recommended by the National Academy of Sciences and the Blue Ribbon Commission on America’s Nuclear Future, the Department of Energy is planning to conduct physical demonstrations on rail-sized spent nuclear fuel transportation casks. As part of the project, called the Spent Nuclear Fuel Package Performance Demonstration (PPD), the DOE is considering a number of demonstrations based on regulatory tests and realistic transportation scenarios, including collisions, drops, exposure to fire, and immersion in water.

The Department of Energy’s Office of Environmental Management announced that it has completed the commissioning of a new, nearly $500 million, large-scale ventilation system at its Waste Isolation Pilot Plant, the DOE’s geologic repository for defense-related transuranic waste in New Mexico.

As part of a broader series on the future of the global energy markets, S&P Global has released a new report examining the growing interest in nuclear energy as the solution to many of the problems the energy sector faces.

Cleanup progress at the former Portsmouth and Paducah uranium enrichment plants is helping enable new opportunities for local communities to continue advancing U.S. energy and U.S. security goals, according to Joel Bradburne, manager of the Department of Energy’s Portsmouth Paducah Project Office (PPPO).

Seven members of the inaugural Nuclear News 40 Under 40 came together on March 4 to discuss the current state of nuclear energy and what the future might hold for science, industry, and the public in terms of nuclear development.

To hear more insights from this talented group of young professionals, watch the “40 Under 40 Roundtable: Perspectives from Nuclear’s Rising Stars” on the ANS website.

Scientists at Idaho National Laboratory continue to make progress on the Molten Chloride Reactor Experiment (MCRE), which entails research and development for the first operational advanced nuclear reactor to use a mixture of molten chloride salt and uranium as fuel and coolant. The experiment is evaluating the safety and physics of the molten chloride fast reactor that Southern Company and TerraPower are planning to build.

The U.S. Supreme Court heard oral arguments on Wednesday in the Nuclear Regulatory Commission’s licensing of Interim Storage Partners’ consolidated interim storage facility in Andrews County, Texas. Both the NRC and ISP petitioned the Supreme Court to review a decision by the 5th Circuit Court of Appeals that invalidated the NRC-granted license for the facility. Those two cases were consolidated into one, NRC v. Texas, which was heard by the court.

Aiming to deploy the nation's first small modular reactor, TerraPower has announced contracts for the final long-lead items needed for its Natrium unit, currently under construction in Wyoming.

Penn State and Westinghouse Electric Company are working together to site a new research reactor on Penn State’s University Park, Pa., campus: Westinghouse’s eVinci, a HALEU TRISO-fueled sodium heat-pipe reactor. Penn State has announced that it submitted a letter of intent to host and operate an eVinci reactor to the Nuclear Regulatory Commission on February 28 and plans to engage with the NRC on specific siting decisions. Penn State already boasts the Breazeale reactor, which began operating in 1955 as the first licensed research reactor at a university in the United States. At 70, the Breazeale reactor is still in operation.

The American Nuclear Society’s Chicago–Great Lakes Local Section hosted a presentation on February 27 on developments at the molten salt research reactor at Abilene Christian University’s Nuclear Energy Experimental Testing (NEXT) Lab.

A recording of the presentation is available on the ANS website.

Advanced reactor company Moltex Energy Canada said it has successfully validated its waste to stable salt (WATSS) process on used nuclear fuel bundles from an unnamed Canadian commercial reactor through hot cell experiments conducted by Canadian Nuclear Laboratories.

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 next opportunity to earn professional engineer (PE) licensure in nuclear engineering is this fall, and now is the time to sign up and begin studying with the help of materials like the online module program offered by the American Nuclear Society.

The American Nuclear Society election is now open. Members can vote for the Society’s next vice president/president-elect and treasurer as well as six board members (four U.S. directors, one non-U.S. director, and one student director). Completed ballots must be submitted by 1:00 p.m. (EDT) on Tuesday, April 15, 2025.

The French magnetic confinement fusion tokamak known as WEST maintained a plasma in February for more than 22 minutes—1,337 seconds, to be precise—and “smashed” the previous record plasma duration for a tokamak with a 25 percent improvement, according to the CEA, which operates the machine. The previous 1,006-second record was set by China’s EAST just a few weeks prior. Records are made to be broken, but this rapid progress illustrates a collective, global increase in plasma confinement expertise, aided by tungsten in key components.

A panel on the potential of artificial intelligence to accelerate small modular reactors was held at the World Governments Summit (WGS) in February in Dubai, United Arab Emirates. The OECD Nuclear Energy Agency cohosted the event, which attracted leaders from developers, IT companies, regulators, and other experts.
