Westinghouse Electric Company has completed the front-end engineering and experiment design (FEEED) for a prototype microreactor at Idaho National Laboratory, the Department of Energy recently announced. The one-fifth scale version of eVinci, Westinghouse’s 5-MWe sodium-cooled heat pipe design, is one of three reactors that could be tested at the National Reactor Innovation Center’s (NRIC) DOME test bed “as early as 2026,” the DOE said.

On July 28, 2023, the Department of Energy launched its Cleanup to Clean Energy initiative, an effort to repurpose underutilized DOE-owned property—portions of which were previously used in the nation’s nuclear weapons program—into the sites of clean-energy generation.

Nuclear powerhouse Constellation announced today the signing of a 20-year power purchase agreement with Microsoft that will pave the way for the restart of Three Mile Island Unit 1—under a new name to honor Chris Crane, former chief executive of Exelon when Constellation was part of the larger company.

Nuclear science and technology is uniquely positioned to be a gateway for curiosity and exploration for students in grades K–12. Its study examines the literal fabric of reality, it has applications from the tiniest to the grandest of scales. It’s a constantly evolving industry with a bright future of discoveries and new technologies, and it’s an essential factor in our global effort to reduce carbon emissions and transition to cleaner energy sources. Frankly, learning about and doing things with atoms is pretty cool, from a kid’s perspective.

The Department of Energy’s Office of Environmental Management announced yesterday that waste processing operations have resumed at the Integrated Waste Treatment Unit (IWTU) at the Idaho National Laboratory Site. The resumption of operations follows the completion of two maintenance campaigns at the radioactive liquid waste treatment facility.

Microreactor developer Aalo Atomics and municipal electric utility Idaho Falls Power have developed a memorandum of understanding that could lead to the siting of seven sodium-cooled microreactors and a power purchase agreement for Idaho Falls.
The NEXT Lab at ACU has been built to house and test the university’s new molten salt reactor design. (Photo: Rusty Towell/ACU)
I really think so. Especially after visiting Abilene Christian University’s new Dillard Science and Engineering Research Center, the home of the Nuclear Energy Experimental Testing (NEXT) Lab and where the university will test its new molten salt research reactor design. The visit was part of the 12th Thorium Energy Alliance Conference. NEXT Lab director and program manager Rusty Towell anticipates that the research reactor will be operational in two years, and I believe it will. What was most impressive is that the reactor is suited to be scaled to any size from small to large—a key feature in any decarbonized world.

The Nuclear Regulatory Commission issued a construction permit yesterday to Abilene Christian University, giving ACU and its partners the go-ahead to build the Molten Salt Research Reactor (MSRR) facility on its Abilene, Texas, campus. The 1-MWt research reactor is the first molten salt–fueled reactor to get a construction permit from the NRC. After Kairos Power’s Hermes, it is the second non–light water reactor construction permit issued by the NRC.

The Pennsylvania Department of Environmental Protection (DEP) expressed its confidence in the decommissioning work taking place at the damaged Three Mile Island Unit 2 during a recent meeting of the TMI-2 Community Advisory Panel (CAP). “We cannot be more pleased with the progress being made,” said Dwight Shearer, director of the DEP, during the meeting, held on September 13 in Middleton, Pa.

New research into the dynamics and structure of high-temperature liquid uranium trichloride (UCl3) salt—a potential fuel for molten salt reactors—has been published in the Journal of the American Chemical Society. A recent news release from Oak Ridge National Laboratory describes how researchers from ORNL, Argonne National Laboratory, and the University of South Carolina used ORNL’s Spallation Neutron Source (SNS) to document the unique chemistry of liquid UCl3 “for the first time.”

Start talking about dust in a vacuum, and some people will think of household chores. But dust has featured in recent nuclear science and engineering headlines in curious ways: ITER is deploying oversized dust covers inspired by space satellites in the south of France, while at Yale University, researchers have watched every move of a dust-sized particle levitating in a laser beam for telltale twitches that indicate radioactive decay.
