Cold, powerful magnet will help control hot plasma in fusion reactor
A magnet so powerful it could lift an aircraft carrier six feet into the air was designed in a project managed by Oak Ridge National Laboratory. It will be used in an international experimental reactor in southern France to produce energy using fusion, the same process used by the sun and other stars to create heat and light. If successful, the reactor could revolutionize energy production, potentially showing how to provide a nearly limitless energy supply without planet-warming carbon dioxide emissions or long-lived radioactive wastes.
Six modules for the reactor’s central superconducting magnet, plus a spare, are being made by General Atomics in Poway, California. Two of the modules have already been shipped to France. Two more are completed, with one of those expected to ship this year. The remaining three are more than 60% complete, and manufacturing should be done this year, said John Smith, General Atomics senior director of engineering and projects.

For decades, Oak Ridge made stable isotopes. Those are non-radioactive forms of atoms that can be used in medicine and industry, and for research and national security.
ORNL to receive $497 million in Inflation Reduction Act funding
Oak Ridge National Laboratory will receive $497 million from the Inflation Reduction Act for projects that include nuclear fusion and neutron research, supercomputing, materials science, and radioisotope production. More than half of the money, 52% of it, will be used for U.S. contributions to an international nuclear fusion project.
ORNL’s $497 million is about one-third of the $1.55 billion provided to the U.S. Department of Energy’s Office of Science by the Democrat-led Congress under the IRA. President Joe Biden signed the IRA, which included a range of provisions and passed along party lines, into law in August. It provides money for more than 52 DOE projects already in the works.
Crews demolish ORNL reactor once used for aircraft nuclear propulsion research
Workers have demolished a nuclear reactor that was built at Oak Ridge National Laboratory in the 1950s for studies that were part of the federal aircraft nuclear propulsion program.
It’s the first demolition of a reactor in the ORNL central campus area. The demolition was reported to be completed ahead of schedule.
The Bulk Shielding Reactor, also known as Building 3010, was built in the 1950s for radiation shielding studies as part of the federal aircraft nuclear propulsion program. It included a 27-foot-deep reactor pool filled with water to shield the radioactive components contained in the pool, according to the U.S. Department of Energy Office of Environmental Management. Its mission changed to a general-purpose research reactor in 1963, and it was shut down permanently in 1991.
The reactor was demolished by cleanup contractor UCOR, working for DOE’s Oak Ridge Office of Environmental Management (OREM).

Note: This story was updated at 1 p.m. Nov. 12.
Oak Ridge National Laboratory has started a research project to investigate using hydrogen fuel in a railroad engine to reduce carbon dioxide emissions and help fight climate change. Rail is one of the industries considered challenging to decarbonize along with aviation and shipping.
Researchers at ORNL and Argonne National Laboratory near Chicago will use a large single-cylinder 375-horsepower Wabtec engine that will burn a mixture of hydrogen and diesel fuel, which is what locomotives burn now. Under four-year agreements, the researchers will study things like engine hardware, fuel mixtures, and ignition strategies. Other low-carbon fuels could also be studied.
“We are excited to be a part of this collaboration because it addresses the need to decarbonize the rail industry by advancing hydrogen engine technology for both current and future locomotives,” said Josh Pihl, an ORNL distinguished researcher and group leader for applied catalysis and emissions research. “It is also a perfect example of how a DOE-funded collaboration between industry and national laboratories can accelerate the development and commercialization of technologies to help reduce carbon emissions from transportation.”
The 15.7-liter engine, larger than a tractor-trailer motor, was recently installed in garage-size research space at the National Transportation Research Center, an ORNL campus in Hardin Valley. ORNL had a ribbon-cutting ceremony for the engine research project on Wednesday.

The U.S. Department of Energy has decided to build a nuclear test reactor at Idaho National Laboratory to study fuels and materials.
Besides INL, Oak Ridge National Laboratory had been considered as a potential site for the Versatile Test Reactor. ORNL remains one of five national laboratories that are partners on the project. DOE said building the test reactor at INL is its preferred alternative.
Crews prepare former ORNL reactors for demolition
The U.S. Department of Energy and cleanup contractor UCOR are preparing to demolish research reactor facilities at Oak Ridge National Laboratory.
Crews are nearing the final stages of deactivation inside two former research reactor facilities: the Bulk Shielding Reactor, known as Building 3010, and the Low Intensity Test Reactor, known as Building 3005, according to a newsletter published by DOE’s Office of Environmental Management. They are also beginning efforts at the Oak Ridge Research Reactor, known as Building 3042.
The work is overseen by DOE’s Oak Ridge Office of Environmental Management, or OREM.
These structures are located in the heart of ORNL, and their demolition will eliminate risks, clear land for research missions, and enhance access to a component of the Manhattan Project National Historical Park, the department said.
