Four utilities form the Great Plains New Nuclear Consortium

December 3, 2025, 12:00PMNuclear News

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.

At the time of this writing, it is only a few days before the American Nuclear Society’s 2025 Winter Conference & Expo in Washington, D.C., which is set to be an unmissable gathering of key nuclear leaders from across the United States and the world. Over the past three weeks, I have been working doggedly to obtain nearly $500,000 in sponsorships and recruit speakers for the conference.

I am thankful for the many generous donors—such as the Tennessee Valley Authority and Constellation—who continue to enable ANS to serve its members, in part by putting on the best conferences we possibly can.

I conducted much of my fundraising and recruitment while I was traveling to represent ANS at various universities, laboratories, and conferences. As I’ve mentioned before, I am focused on developing criteria around where ANS presidents travel to ensure that our resources are spent wisely; I am working with ANS past president Gail Marcus (2001–2002) to develop those criteria now, and in the meantime, I have been judicious in deciding which invitations to accept.

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.

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.

Reality of the road ahead

As 2025 winds down, it seems nuclear energy in the U.S. is now well on its way toward a renaissance, or resurgence, or whatever optimistic term you may use in your daily conversations.

New reactor designs, projects, and partnerships are being announced on a near-weekly basis; valuations of publicly traded nuclear companies are hovering near all-time highs; and AI’s thirst for reliable, clean electricity remains largely unquenched. The overall investment climate for nuclear energy has thawed dramatically. These days, it seems everyone from big Wall Street banks to individual investors is trying to get a piece of the nuclear action.

It’s the perfect time to talk about failure.

Yes, I know “nuclear failure” is not a topic on which we in the nuclear community like to dwell. For those of a certain age, it brings back bad memories of events beyond our control that shifted the trajectory of companies, careers, and lives for decades.

TerraPower’s Natrium plans for Wyoming, Utah move forward

TerraPower has reported a number of developments related to its Natrium sodium fast reactor project. In the project’s fifth round of procurement awards, the company awarded three supplier contracts to support the Natrium plant’s construction, which is underway in Kemmerer, Wyo., and is expected to be completed in 2030. AvanTech will design advanced sodium processing system modules and supporting skids for the Natrium plant, as well as fabricate and deliver the test and fill facility cold trap skid. Structural Integrity Associates will design and fabricate the sodium cover gas gamma spectroscopy analysis cabinet, a radiation monitoring system. PAR Systems will design and fabricate the pool handling machine, a specialized crane system for spent fuel pool operations.
