Progress continues for TerraPower’s Natrium plant, with the latest win coming in the form of a state permit for construction of nonnuclear portions of the advanced reactor.
The media have gleefully resurrected the language of a past nuclear renaissance. Beyond the hype and PR, many people in the nuclear community are taking a more measured view of conditions that could lead to new construction: data center demand, the proliferation of new reactor designs and start-ups, and the sudden ascendance of nuclear energy as the power source everyone wants—or wants to talk about.
Once built, large nuclear reactors can provide clean power for at least 80 years—outlasting 10 to 20 presidential administrations. Smaller reactors can provide heat and power outputs tailored to an end user’s needs. With all the new attention, are we any closer to getting past persistent supply chain and workforce issues and building these new plants? And what will the election of Donald Trump to a second term as president mean for nuclear?
As usual, there are more questions than answers, and most come down to money. Several developers are engaging with the Nuclear Regulatory Commission or have already applied for a license, certification, or permit. But designs without paying customers won’t get built. So where are the customers, and what will it take for them to commit?
TerraPower announced this week that it has awarded the major manufacturing contracts for its Natrium plant reactor enclosure system.
These vendor awards help advance deployment and commercialization of what the company is calling “America’s first advanced reactor,” according to TerraPower’s press release. The news is also a major milestone in establishing the advanced nuclear supply chain, the company added.
There is extra significance to the American Nuclear Society holding its annual meeting in Orlando, Florida, this past week. That’s because in 1967, the state of Florida passed a law allowing Disney World to build a nuclear power plant.
TerraPower announced today that it has signed a term sheet with ASP Isotopes Inc. as the first step of a planned investment in the construction of a high-assay low-enriched uranium (HALEU) enrichment facility and the eventual purchase of HALEU produced at the facility to fuel its Natrium fast reactors.
The Nuclear Regulatory Commission has notified TerraPower that the company has delivered enough information on volcanic risk activity around its proposed small modular reactor project in Kemmemer, Wyo., to satisfy the federal review process.
TerraPower has announced its selection of industry experts Sargent & Lundy to design the Kemmerer Training Center for its Natrium reactor demonstration project in Wyoming.
A public hearing in Kemmerer, Wyo., drew dozens of comments and questions about TerraPower’s plans to build the Natrium nuclear reactor demonstration project in the coming years.
Dominion Energy Virginia has issued a request for proposals from leading nuclear companies to study the feasibility of putting a small modular reactor at its North Anna nuclear power plant.
While the utility says it is not a commitment to build an SMR at the site, the RFP is “an important first step in evaluating the technology and the North Anna site to support Dominion Energy customers’ future energy needs consistent with the company’s most recent Integrated Resource Plan.”
“What can the atom do for you, other than produce electricity from nuclear reactors?” That was the question asked and answered during an ANS Annual Conference special plenary session on June 18, introduced by ANS President Ken Petersen and organized by the ANS Young Members Group. An expert panel discussed radioisotopes and their supply chains in the context of cancer treatment, product sterilization, power for remote applications, and used nuclear fuel recycling.
A 60-year-old Wyoming industrial machinery company is partnering with nuclear innovator BWX Technologies to deploy 50-megawatt microreactors in America’s heartland over the coming years to provide carbon-free heat and power for industrial users.
A ceremony in Wyoming yesterday marked the official start of construction of TerraPower’s planned Natrium reactor demonstration project.
While currently awaiting final review from the U.S. Nuclear Regulatory Commission, TerraPower is moving forward with nonnuclear construction work at a retired coal plant near Kemmerer, Wyo. The groundbreaking brought together TerraPower leaders, government officials, Natrium project partners, industry advocates, and community supporters.
The Nuclear Regulatory Commission this week announced the window is open for members of the public to request a hearing on the construction permit application for TerraPower’s Natrium nuclear power plant, which is set to be built near Kemmerer, Wyo.

As advocates for the environment, national security, and U.S. prosperity, and as believers that the substantial global expansion of nuclear energy is essential to these interests, let’s take a moment to recognize how far we have come.
In recent years, much has changed. Public opinion polls show increasingly broad support for nuclear energy, which has bipartisan and bicameral support in Congress. The U.S. is on the cusp of achievements that could usher in a new era of nuclear energy and reestablish U.S. global leadership. The prevailing question is no longer whether we need nuclear energy, but rather, how much more nuclear power do we need, how can we enable first movers, and how quickly can we deploy new reactors.
TerraPower announced May 29 that it will work with Framatome North America to fund the high-assay low-enriched uranium (HALEU) metallization pilot plant that Framatome is building at its fuel fabrication facility in Richland, Wash. A successful demonstration of Framatome’s capability of converting enriched uranium oxide to HALEU metal will “support the development of the domestic HALEU supply chain,” both companies say.
The U.S. Nuclear Regulatory Commission has formally accepted TerraPower’s small modular reactor construction permit application and is scheduling it for review.
The company’s Natrium reactor demonstration project—the nation’s first commercial advanced reactor of its kind—would be built on land in Wyoming near one of the state’s retiring coal plants. Kemmerer Power Station Unit 1 would operate as a 345-MW sodium-cooled reactor in conjunction with molten salt–based energy storage.

High-assay low-enriched uranium (HALEU) has emerged as a popular fuel choice for advanced small modular reactors due to its long power production periods before refueling. It is currently being pursued by TerraPower, X-energy, BWX Technologies, Kairos, Oklo, and other reactor companies. HALEU has a uranium-235 enrichment ranging from 5 percent to 20 percent, whereas traditional LWRs use low-enriched uranium fuel enriched up to 5 percent.
HALEU will provide power for longer durations, compared with traditional LWRs. But could it also provide an opportunity for more rapid proliferation, as is speculated in a 2023 National Academy of Sciences report on advanced nuclear reactors (nap.nationalacademies.org/catalog/26630/)?
If a nuclear proliferator conspires to divert fresh nuclear fuel for weapons production when it has not been used in a reactor, the effort required in separative work units (SWUs) to enrich U-235 from 5 percent to 90 percent and that required to enrich from 20 percent to 90 percent are both very small, compared with the effort required to enrich U-235 from its natural abundance to the initial 5 percent.
Investment banking on higher demand for SMR and large nuclear reactors
BWX Technologies announced today plans to expand and add advanced manufacturing equipment to its manufacturing plant in Cambridge, Ontario, Canada.
A $36.3 million USD ($50M CAD) expansion will increase the plant’s size by 25 percent—to 280,000 square feet—and another $21.7 million USD ($30M CAD) will be spent on new equipment to increase and accelerate its output of large nuclear components. The investment will increase capacity and create more than 200 long-term jobs for skilled workers, engineers, and support staff, according to the company.
TerraPower’s application to build its Natrium nuclear power plant near Kemmerer, Wyo., is available for public viewing on the Nuclear Regulatory Commission website.
TerraPower today submitted its formal construction permit application to the Nuclear Regulatory Commission for the Natrium reactor demonstration project—a milestone submission for the nation’s first commercial advanced reactor of its kind.
