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.

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.

“We cannot eliminate our way to net zero,” said Sen. Joe Manchin (D., W.Va.) during a visit to the ITER site in Cadarache, France, on March 25. “We have to innovate, not eliminate, our way to carbon neutrality."
Manchin was joined by Ali Nouri, assistant secretary for congressional and intergovernmental affairs at the Department of Energy; Kathy McCarthy, director of the U.S. ITER Project Office; and other U.S. officials for a tour of the ITER Assembly Hall led by ITER chief scientist Tim Luce, head of the ITER Science and Operations Domain. The visit was described in an ITER Newsline article published on March 28.

The White House Office of Science and Technology Policy and the Department of Energy cohosted the White House Summit on Developing a Bold Decadal Vision for Commercial Fusion Energy on March 17. The livestreamed event brought together fusion leaders from government, industry, academia, and other stakeholder groups to showcase recent achievements in fusion research and discuss the administration’s strategy to support the development of commercial fusion energy. Energy Secretary Jennifer Granholm’s announcement of a new agency-wide fusion energy initiative and a funding opportunity worth $50 million for magnetic confinement fusion research made March 17 a lucky day indeed for the U.S. fusion energy community.

In the 13 months since a fuel element failure triggered a scram of the research reactor at the National Institute of Standards and Technology’s NIST Center for Neutron Research (NCNR), the event and its causes have been scrutinized by both NIST and the Nuclear Regulatory Commission.
Initial conclusions from an NRC special inspection released on March 16 confirm that while public health and safety was maintained during and after the event, and doses to reactor facility staff were well below regulatory limits, a safety limit was violated when the temperature of the fuel cladding of a single fuel element in the 20-MWt research reactor reached a temperature high enough to partially melt the element.
