The Department of Energy has selected the Tennessee Valley Authority and Holtec Government Services to support the early deployments of light water small modular reactors in the United States. The companies will each receive as much as $400 million in federal cost-shared funding to advance their initial SMR projects in Tennessee and Michigan, respectively, including follow-on projects and associated supply chains.

Four public electric utilities—three based in Nebraska and one in Oklahoma—recently signed a memorandum of understanding to form the Great Plains New Nuclear Consortium. The first goal of that new consortium is to explore the feasibility of deploying 1–2 GW of new nuclear (potentially in the form of small modular reactors) within Nebraska.

The Nuclear Regulatory Commission recently announced that it has completed its final safety evaluation (SE) for the construction permit application for Kemmerer Power Station Unit 1 in Kemmerer, Wyo. The application was submitted by TerraPower on behalf of its wholly owned subsidiary, US SFR Owner (USO).

The Department of Energy recently announced that General Atomics has successfully completed the conceptual design of its new helium gas–cooled fast modular reactor (FMR). This milestone moves the company one step closer to a target demonstration in the 2030s.

Here is a recap of recent industry happenings:

ADVANCED REACTOR MARKETPLACE

Agreement signed on advanced nuclear technology in space

Texas-based space technology and orbital logistics developer Space Ocean Corporation and New Mexico–­based space nuclear power systems developer Space Nuclear Power Corporation (SpaceNukes) have signed a letter of intent to explore the integration of advanced nuclear reactor technology into future space missions. Space Ocean agreed to test SpaceNukes’ 10-kilowatt microreactor aboard its ALV-N satellite and, if performance criteria are met, to use SpaceNukes as a core supplier of reactors for future Space Ocean lunar and planetary missions. The companies also agreed to examine the integration of fluid delivery systems with reactor modules, to collect operational data to support technology readiness certification, and to form a joint working group to pursue additional space infrastructure and commercial opportunities.

Six universities in Africa, Asia, Latin America, and the Caribbean now offer postgraduate courses in nuclear law with support from the International Atomic Energy Agency, expanding legal education in the nuclear community.

One of the executive orders issued by President Trump in November —“Launching the Genesis Mission”—focuses on a national effort to accelerate the use of AI in scientific research. The Genesis Mission EO preceded a reorganization of the Department of Energy and further tightens links between science and security under the administration’s quest for “global technology dominance in the development of artificial intelligence.”

In a recent press release, the Department of Energy announced an organizational realignment aimed at “expanding American energy production, accelerating scientific and technological leadership, and ensuring the continued safety and readiness of the nation’s nuclear weapons stockpile.”

Advanced reactor developer X-energy has announced that it has closed an oversubscribed Series D financing round of approximately $700 million. The funding proceeds are expected to be used to help continue the expansion of its supply chain and the commercial pipeline for its Xe-100 advanced small modular reactor and TRISO-X fuel, according the company.

Hideyo Hanazumi, governor of Niigata Prefecture in Japan, has approved the restart of two reactors at Kashiwazaki-Kariwa nuclear power plant. The seven-unit facility, operated by Tokyo Electric Power Company, is the largest nuclear power plant in the world. It has been shut down since the March 2011 earthquake and tsunami struck the country, severely damaging TEPCO’s Fukushima Daiichi plant.

The Nuclear Regulatory Commission announced that it has received the first portion of a construction permit application from Oklo subsidiary Atomic Alchemy that requests permission to build four nonpower reactors for a radioisotope production facility at Idaho National Laboratory. The submission is now available for public inspection on the NRC website.

As President Trump hosted Saudi Crown Prince Mohammed bin Salman at the White House on November 19, Energy Secretary Chris Wright confirmed that the United States and Saudi Arabia have signed a “historic” deal on cooperation in the civilian nuclear energy sector. The “Joint Declaration on the Completion of Negotiations on Civil Nuclear Cooperation” is seen as an important part to strengthen U.S. influence in the Gulf region to counter the influence of Iran, Russia, and China.

The Department of Energy’s Office of Nuclear Energy is requesting comments on a draft voluntary agreement for the Nuclear Fuel Cycle Defense Production Act (DPA) Consortium, with a short deadline of November 24 for comments.

Notice of the request for comments, along with the text of the draft voluntary agreement, was published in the November 17 Federal Register.

The Department of Energy announced on November 18 that it has closed on a $1 billion loan through its Loan Programs Office to Constellation to aid in financing the restart of the 835-MWe Crane Clean Energy Center, formerly Three Mile Island-1.

AI for energy, and energy for AI: that is the new refrain. But can nuclear power plants be deployed at the pace needed for substantial and timely contributions to the energy infrastructure? For Westinghouse, delivering its AP1000 on time and on budget in the United States is a challenge not yet accomplished, while newcomers like Aalo Atomics are turning to AI to speed design, permitting, and construction.

As part of the Janus Program, announced in October, the Department of the Army is seeking potential commercial vendors to build microreactor power plants at nine military installations that are under consideration.

Nieh

Earlier today, the U.S. Senate officially confirmed Ho Nieh in a 66–32 vote to serve as a commissioner on the U.S. Nuclear Regulatory Commission through the remainder of a term that will expire June 30, 2029. All present Republicans, alongside 15 Democrats and one Independent, cast their votes in favor of Nieh, who was nominated by President Trump in July and fills the seat left vacant following the dismissal of former commissioner Christopher Hanson.

NRC details: The commission leading the NRC now comprises four members. Nieh joins Chair David Wright and commissioners Bradley Crowell and Matthew Marzano. One spot remains unfilled after the resignation of Annie Caputo in July. President Trump nominated Douglas Weaver earlier this month to fill Caputo’s seat.

Due to the days lost to the government shutdown, the Nuclear Regulatory Commission has extended the public comment period for a draft environmental impact statement for the TX-1 advanced nuclear fuel fabrication facility being built in Oak Ridge, Tenn.

Utah Gov. Spencer Cox joined Brigham City Mayor D. J. Bott this week to announce a new partnership among the state, city, Hi Tech Solutions, and Holtec International. The partnership plans to develop a “full-scale nuclear energy ecosystem” based in Brigham City that will feature advanced manufacturing, workforce development, and Holtec’s SMR-300.

Valar Atomics has announced that its Nova Core achieved zero-power criticality on November 17 at Los Alamos National Laboratory’s National Criticality Experiments Research Center (NCERC) at the Nevada National Security Site.
