The Defense Innovation Unit (DIU), a Department of Defense organization focused on swiftly putting commercial technology to use in the U.S. military, has awarded contracts for two nuclear technologies—compact fusion and radioisotope heat—for spacecraft that could carry a high-power payload and freely maneuver in cislunar space. The objective is to accelerate ground and flight testing and launch a successful orbital prototype demonstration of each approach in 2027.

The Versatile Test Reactor, a custom-designed sodium-cooled fast neutron spectrum test reactor, is one step closer to its goal of providing data to accelerate research, development, and demonstration of diverse advanced reactor designs. The Department of Energy released the Final Versatile Test Reactor Environmental Impact Statement (Final VTR EIS) on May 13, and 30 days after its anticipated May 20 publication in the Federal Register, the DOE will issue a Record of Decision on the project.

The Massachusetts Institute of Technology’s Plasma Science and Fusion Center (PSFC) recently announced it will expand its involvement in fusion energy research and education under a new five-year agreement with Commonwealth Fusion Systems (CFS), a fusion energy company that got its start at MIT and is now building what it says will be the world’s first net-energy fusion machine—the demo-scale SPARC.
“CFS will build SPARC and develop a commercial fusion product, while MIT PSFC will focus on its core mission of cutting-edge research and education,” said PSFC director Dennis Whyte in describing the collaboration.

The Thermal Hydraulic Experimental Test Article (THETA) at Argonne National Laboratory is now operating and providing data that could support the licensing of liquid-metal fast reactor designs by validating thermal-hydraulic and safety analysis codes. The new equipment has been installed in Argonne’s Mechanisms Engineering Test Loop (METL), and its first experiments are supporting data validation needs of Oklo, Inc., by simulating normal operating conditions as well as protected and unprotected loss-of-flow accidents in a sodium-cooled fast reactor.

From refugee in Bangladesh to top nuclear engineer at Idaho National Laboratory, ANS member Yasir Arafat has led quite an interesting life, as described in a recent online profile written by Donna Kemp Spangler for the INL website. Arafat is leading the development of the Department of Energy’s Microreactor Applications Research Validation and EvaLuation (MARVEL) project at INL. The profile notes that MARVEL, which Arafat envisioned soon after joining INL in 2019, is scheduled to be “built and demonstrated at INL’s Transient Reactor Test Facility and connected to the world’s first nuclear microgrid within two years.”

Battelle Energy Alliance (BEA), the management and operating contractor for Idaho National Laboratory, has signed a five-year memorandum of understanding with the State of Wyoming to collaborate on the research, development, demonstration, and deployment of advanced energy technologies and approaches, with a special focus on advanced nuclear.

Concrete structures built to last for decades, including reactor containment buildings and other nuclear power plant structures, are subject to the alkali-silica reaction (ASR), a reaction between alkali ions found in cement and silica, the two main components of concrete. The reaction forms a gel that absorbs water and expands over time, causing a buildup of pressure within the concrete that can eventually lead to cracking and deterioration.
Researchers at Argonne National Laboratory have successfully used electrochemical impedance spectroscopy (EIS) to detect ASR in the lab and believe it could be used for cost-effective, nondestructive testing at nuclear power plants.

Michigan State University’s Facility for Rare Isotope Beams (FRIB) officially opened yesterday with a ribbon-cutting ceremony attended by Energy Secretary Jennifer Granholm, elected officials, and guests who had supported the project during its planning and construction, including ANS Executive Director/Chief Executive Officer Craig Piercy. They were there to celebrate the completion—on time and within budget—of the world’s most powerful heavy-ion accelerator and the first accelerator-based Department of Energy Office of Science user facility located on a university campus.

After identifying the research requirements for the SAS-VW, a process of engineering design, prototyping, and implementation is performed. (Image: General Atomics)
Researchers at the DIII-D National Fusion Facility (DIII-D) are preparing to test a new method that could enable future fusion power plants to withstand the heat and particle flow created by the fusion reaction, General Atomics reported this week.
Savannah River National Laboratory recently oversaw a demonstration of a new radiological inspection technology called iGART, a ground-based robot that conducts radiological and nuclear inspections. The DOE’s Office of Environmental Management used the demonstration at the Savannah River Site to determine if there is an application value for iGART at SRS or other EM sites. (Photos: DOE)
The Department of Energy’s Office of Environmental Management is looking to continue developing technology to aid in site cleanup activities if its fiscal year 2023 budget request is approved. The $7.64 billion budget request includes about $25 million for EM’s Technology Development Office.

According to the Department of Energy’s Princeton Plasma Physics Laboratory, recent simulations and analysis demonstrate that the design of its flagship fusion facility, the National Spherical Torus Experiment Upgrade (NSTX-U), which is currently under repair, could serve as a model for an economically attractive next-generation fusion pilot plant.

Connecting nuclear engineers and scientists with space exploration missions has been a focus of the American Nuclear Society’s Aerospace Nuclear Science and Technology Division since its creation in 2008. One of the main ways those connections are made is through the Nuclear and Emerging Technologies for Space (NETS) conference, which the division supports in conjunction with the National Aeronautics and Space Administration.
