The Carbon Free Power Project (CFPP) called for the deployment of six 77-MWe pressurized water reactors at Idaho National Laboratory that would provide power to INL and to Utah Associated Municipal Power Systems (UAMPS) customers in Utah and surrounding states. But UAMPS and NuScale Power mutually agreed to end the project in late 2023, ending a first-of-a-kind SMR project that was years in the making.

Total project costs, had it been completed, were estimated at $8.03 billion, with $1.36 billion coming from the Department of Energy as part of a 10-year, noncompetitive, cost-share award.

On Wednesday, Idaho National Laboratory announced that the National Reactor Innovation Center’s Demonstration of Microreactor Experiments (DOME) test bed is now “open for business.”

With DOME’s opening, microreactor developers will soon be able to test, demonstrate, and validate their reactor designs. Rian Bahran, the Department of Energy’s deputy assistant secretary for nuclear reactors, called this “essential infrastructure” a “testament to our commitment to a robust nuclear future” and a key tool for “accelerating the development and deployment” of new energy technologies.

Nuclear technology start-up Project Omega announced that it has been awarded a contract through the Department of Energy’s Advanced Research Projects Agency-Energy (ARPA-E) to advance used nuclear fuel recycling. Project Omega said the award will be used to validate key components of its molten salt electrochemical recycling platform designed to process UNF, recover valuable isotopes, and reduce long-term waste management challenges.

The White House is requesting $1.5 billion for the Department of Energy’s Office of Nuclear Energy in the fiscal year 2027 budget proposal, about 9 percent less than the previous year.

The request from the Trump administration is one of several associated with nuclear energy in the proposal, which was released Friday. Congress still must review and vote on the budget.

The Department of Energy announced the completion of a proof-of-concept demonstration of the use of Everstar’s AI tool to generate chapter 5 of an NRC license application from preliminary safety documents.

The 208-page document was created by the AI tool in approximately one day. According to the DOE, it would typically take a team of people between four and six weeks to complete this work.

The American Nuclear Society recently hosted a panel discussion featuring prominent figures from the nuclear sector who discussed the industry’s ongoing push for criticality.

Yasir Arafat, chief technical officer of Aalo Atomics; Jordan Bramble, CEO of Antares Nuclear; and Rita Baranwal, chief nuclear officer of Radiant Industries, participated in the discussion and covered their recent progress in the Department of Energy’s Reactor Pilot Program. Nader Satvat, director of nuclear systems design at Kairos Power, gave an update on the company’s ongoing demonstration projects taking place outside of the landscape of DOE authorization.

It has been 10 months since President Trump signed several executive orders that have reshaped the nuclear energy industry and set lofty goals for initiatives like the development and deployment of new nuclear technology.

One such initiative, the DOE’s Nuclear Reactor Pilot Program, calls for at least 3 of the 11 reactors in the program to achieve criticality by July 4, 2026. Some have questioned whether this target is feasible.

MARVEL, the Microreactor Applications Research Validation and Evaluation project at Idaho National Laboratory, has had its preliminary documented safety analysis approved by the Department of Energy, marking a milestone in its development and serving as a potential outline for other microreactors in development.

The Department of Energy is set to expand on its Reactor Pilot Program and Fuel Line Pilot Program by introducing the Nuclear Energy Launch Pad, a DOE-led program to integrate the authorization, testing, and operation of reactors and fuel facilities from private nuclear developers. Furthermore, it will include two pathways—Launch Pad INL and Launch Pad USA—with options to access Idaho National Laboratory land or other sites around the nation.

The DOE plans to transition future pilot program applicants to the new Launch Pad model. Application requirements and review criteria will mirror those used in the reactor and fuel line pilot programs, and projects already in those programs will transition to Launch Pad with no need to reapply.

Idaho National Laboratory has announced that the National Reactor Innovation Center’s Molten Salt Thermophysical Examination Capability (MSTEC) facility will begin operations in March 2026.

Providing testing capabilities for molten salts, including fuel salts, MSTEC extends INL’s abilities to advance molten salt reactor technology and provide data needed for safe reactor deployment.

Idaho National Laboratory and computer chip maker Nvidia have announced a public-private partnership to advance nuclear energy deployment through artificial intelligence. According to INL, the collaboration aims to cut reactor development times in half and reduce operational costs by 50 percent by using AI to design, license, manufacture, construct, and operate reactors with human-in-the-loop workflows.

At Idaho National Laboratory, researchers have built a bridge between computer models and the lab’s Microreactor Applications Research Validation and Evaluation (MARVEL) microreactor.

Tony Crawford, an INL researcher and MARVEL’s reactivity control system lead, designed a phone booth–sized surrogate nuclear reactor called ViBRANT, or Visual Benign Reactor as Analog for Nuclear Testing, which uses light instead of neutrons to show a “nuclear” reaction.

As the energy sector faces mounting pressure to grow at an unprecedented pace while maintaining reliability and affordability, nuclear technology remains an essential component of the long-­term solution. Southern Company stands out among U.S. utilities for its proactive role in shaping these next-­generation systems—not just as a future customer, but as a hands-­on innovator.

Sometimes, cops and robbers is more than just a kid’s game. At the Department of Energy’s national laboratories, researchers are channeling their inner saboteurs to discover vulnerabilities in next-generation nuclear reactors, making sure that they’re as safe as possible before they’re even constructed.

The Department of Energy’s Office of Nuclear Energy announced the establishment of the Center for Used Fuel Research (CUFR), to be hosted at the Idaho National Laboratory and focused on spent nuclear fuel performance, canister aging, and the fostering of innovation and collaboration.

According to the DOE, the CUFR is designed to be a national and international hub for applied research that supports and maintains compliance and advances public confidence in the safe storage and transportation of both commercial and DOE-managed spent fuel.

Each year, the Department of Energy’s Nuclear Energy University Program (NEUP) recognizes graduate and undergraduate students for their innovative nuclear energy research. The winners of the Innovations in Nuclear Energy Research and Development Student Competition (INSC) receive honoraria along with travel and conference opportunities, including the chance to present their publications at the annual American Nuclear Society Winter Conference & Expo.

Idaho National Laboratory has announced the creation of the first batch of enriched uranium chloride fuel salt for the Molten Chloride Reactor Experiment (MCRE). INL said that its fuel production team delivered the first fuel salt batch at the end of September, and it intends to produce four additional batches by March 2026. MCRE will require a total of 72–75 batches of fuel salt for the reactor to go critical.

Idaho National Laboratory has selected five teams for its Microreactor Application Research Validation and Evaluation (MARVEL) Project to develop a sodium-potassium–cooled microreactor designed to test microreactor applications, create regulatory processes, and explore electrical and nonelectrical uses.

This week, BWX Technologies, alongside Idaho National Laboratory and the Department of Defense’s Strategic Capabilities Office, announced the arrival of a full core of TRISO fuel at INL’s Transient Reactor Test Facility.

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.
