The Spallation Neutron Source (SNS) at the Department of Energy's Oak Ridge National Laboratory set a world record for accelerator-driven neutron research when its linear accelerator reached an operating power of 1.55 MW, improving on the facility’s original design capability of 1.4 MW. That higher power means more neutrons for researchers who use the facility for neutron scattering research to reach materials science advances, ORNL announced recently.
Georgia Institute of Technology has announced the Consortium for Emerging Technologies and Innovation’s third ETI Annual Summer School, which will focus on advanced manufacturing within the context of nuclear nonproliferation.

Another calendar year has passed. Before heading too far into 2023, let’s look back at what happened in 2022 for the American Nuclear Society and the nuclear community. In today's post that follows, we have compiled from Nuclear News and Nuclear Newswire what we feel are the top nuclear news stories from April through June 2022.
Stay tuned this week for the top stories from the rest of the past year.
But first:
Busby
American Nuclear Society member Jeremy Busby has been named associate laboratory director for the Fusion and Fission Energy and Science Directorate at the Department of Energy’s Oak Ridge National Laboratory, effective January 1.
Busby will oversee the directorate’s facilities, capabilities, and scientists and engineers who are tackling such challenges as extending operations of the current U.S. nuclear reactor fleet, investigating economical and flexible advanced reactor systems, and making fusion energy a viable part of the nation’s energy portfolio.
“ORNL has a proud history of addressing compelling challenges in both fusion and fission energy systems, and I’m honored to contribute to our success moving forward,” Busby said. “ORNL’s Fusion and Fission Energy and Science Directorate has the world-leading expertise to advance the development and deployment of both fusion and fission. Combined with the additional strengths across ORNL’s research and support organizations and ORNL’s unique capabilities, we will fortify our nation’s energy transition.”
Experimentation on the world’s first molten salt reactor to potentially power aircraft was already underway in November 1954, being carried out by the U.S. Air Force. Oak Ridge National Laboratory was the scene for the power-dense, high-temperature reactor experiment known as the Aircraft Reactor Experiment (ARE).
Canadian Nuclear Laboratories (CNL) and General Fusion have announced a memorandum of understanding (MOU) to “develop fusion energy research capabilities within CNL, to support the goal of constructing a potential General Fusion commercial power plant in Canada before 2030.” The plant would follow on a demonstration-scale plant that General Fusion wants to have operating in the United Kingdom by 2027 to validate the performance and economics of the technology.
The Department of Energy’s Office of Environmental Management (EM) said its cleanup contractor UCOR recently completed the first-ever demolition of a reactor in the central campus area at the Oak Ridge National Laboratory in Tennessee.
Just days before COP27 and the U.S. midterm elections, the White House announced $1.55 billion in Inflation Reduction Act (IRA) funding for national laboratories and the launch of a Net-Zero Game Changers Initiative based on a new report, U.S. Innovation to Meet 2050 Climate Goals. Out of 37 research and development opportunities identified, fusion energy was selected as one of just five near-term priorities for the new cross-agency initiative. Together, the announcements signal policy and infrastructure support for fusion energy—the biggest chunk of Department of Energy Office of Science (DOE-SC) IRA funding went to ITER, via Oak Ridge National Laboratory—and for advanced nuclear technologies to power the grid and provide process heat to hard-to-decarbonize industrial sectors.

Tokamak Energy on October 26 announced plans to construct a high field spherical tokamak using high-temperature superconducting (HTS) magnets. Dubbed the ST80-HTS, the machine would demonstrate multiple technologies required to achieve commercial fusion energy, the company says. Tokamak Energy plans to complete the ST80-HTS in 2026 to demonstrate spherical tokamak operations and inform the design of its successor, a fusion pilot plant called ST-E1 that the company says could deliver electricity into the grid in the early 2030s and produce up to 200 MWe.
Temperature milestone: Earlier this year, the company’s ST40 spherical tokamak reached the commercial fusion energy plasma temperature threshold of 100 million °C with what was reported as the highest triple product (an industry measure of plasma density, temperature, and confinement) of any private fusion energy company. The ST40 achieved those results with a plasma volume of less than one cubic meter, which is 15 times less volume than any other tokamak that has achieved the same threshold.
The Department of Energy held a groundbreaking ceremony on October 24 for the Stable Isotope Production and Research Center (SIPRC) at Oak Ridge National Laboratory in Tennessee. The center is being built to expand the nation’s capability to enrich stable isotopes for medical, industrial, and research applications.
LA GRANGE PARK, Illinois – Idaho National Laboratory’s crucial Versatile Test Reactor (VTR) project is the focus of a newly released special issue of Nuclear Science and Engineering, the first and oldest peer-reviewed journal in its field. This special issue of the American Nuclear Society’s flagship journal presents a current snapshot of the nuclear innovation project at INL, which is being developed in partnership among six national labs and a host of industry and university partners.
Work crews at the Department of Energy’s Oak Ridge Site in Tennessee have successfully completed the demolition of the former Criticality Experiment Laboratory. Crews worked this past summer to bring down the dilapidated 1940s-era facility, also known as Building 9213.
In a first for the Department of Energy’s Oak Ridge Site, a former reactor facility is being demolished. The site’s cleanup contractor, UCOR, began tearing down the Bulk Shielding Reactor, also known as Building 3010, last week.
“While this project is not the biggest demolition we’ve undertaken, it carries a lot of significance,” said Laura Wilkerson, acting manager for the Oak Ridge Office of the DOE’s Office of Environmental Management (EM). “It is the first removal of a former reactor at [Oak Ridge National Laboratory], and it is a signal of much more to come at the site in the immediate future.”
X-energy has been having a good year. Not only did Dow announce plans to invest in the company’s high-temperature gas reactor (HTGR) technology and deploy an Xe-100 reactor at a U.S. Gulf Coast facility for power and process heat by 2030, in parallel with the Xe-100 demo planned for Washington state with support from the Advanced Reactor Demonstration Program (ARDP), but X-energy’s fuel subsidiary, TRISO-X, has applied for a fuel facility license and aims to have a commercial fuel plant operating in 2025, and Canadian provinces are signaling their interest in the technology. And while news of Dow’s investment broke with well-deserved fanfare, the company’s serious interest in HTGRs—and federal support for HTGR development—goes way back.
Ultra Safe Nuclear Corporation (USNC) celebrated the opening of its Pilot Fuel Manufacturing (PFM) facility in Oak Ridge, Tenn., on August 18 with a ribbon-cutting ceremony and tour attended by assistant secretary for nuclear energy Kathryn Huff, Tennessee lieutenant governor Randy McNally, U.S. Rep. Chuck Fleischmann (R.), representatives from the offices of Sens. Marsha Blackburn (R.) and Bill Hagerty (R.), and other distinguished guests. The next day, radiological operations began at the privately funded facility, which was designed and built in less than twelve months within an existing industrial building purchased by USNC in 2021.
Delivery of electricity from fusion is considered by the National Academies of Engineering to be one of the grand challenges of the 21st century. The tremendous progress in fusion science and technology is underpinning efforts by nuclear experts and advocates to tackle many of the key challenges that must be addressed to construct a fusion pilot plant and make practical fusion possible.
