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.

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).

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.â€
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 estimates it could cost at least $7.2 billion to convert and dispose of tens of thousands of cylinders of depleted uranium hexafluoride, a dangerous, corrosive waste byproduct of the uranium enrichment process. Some of the waste came from the former K-25 site in Oak Ridge and is now stored in Ohio, but a portion of the converted depleted uranium could eventually be returned to Oak Ridge for use in nuclear weapons.

DOE’s Office of Environmental Management has had about 67,000 cylinders of the depleted uranium hexafluoride (DUF6) stored at two conversion facilities in Paducah, Kentucky, and Portsmouth, Ohio. The facilities convert the DUF6 into two primary products, depleted uranium oxide (a more stable chemical form) and hydrofluoric acid, according to a report by the U.S. Government Accountability Office.

At ORNL, the Versatile Test Reactor would have been at a relatively undeveloped site previously considered for other projects about a mile east of the ORNL main campus. It would have required a new hot cell and a facility for post-irradiation examination and the conditioning of spent nuclear fuel for disposal. It would also have used existing facilities at ORNL, including the Irradiated Fuels Examination Laboratory and the Irradiated Material Examination and Testing Facility.
DOE said building the Versatile Test Reactor at either INL or ORNL would have small environmental consequences, but overall, the consequences would be less at the INL site. Among the reasons: A smaller area would be temporarily disturbed and permanently occupied at INL because of the need to build a new hot cell facility at ORNL. Unlike the INL site, the ORNL location abuts wetlands that would have to be managed or avoided under the Clean Water Act and Tennessee regulations. The removal of trees at ORNL would result in the loss of roosting habitat for sensitive bat species. And although small at both locations, the potential radiological impacts would be lower at INL because the Versatile Test Reactor would be farther from the site boundary and population density is lower near INL than ORNL.

U.S. Department of Energy public bus tours have resumed in Oak Ridge after a two-year pause due to the COVID-19 pandemic.
The tours began running again on July 11, and they are scheduled to continue through November.
“The program is a longtime staple in the community, helping educate residents and visitors about the site’s rich history and current missions,” DOE said in an EM Update newsletter published Tuesday. (EM stands for environmental management.)
The tour program started in 1996 and has attracted tens of thousands of visitors from all 50 states, DOE said.

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.

Thomas Zacharia plans to retire as director of Oak Ridge National Laboratory at the end of 2022 after 35 years at the nation’s largest science and energy laboratory, a press release said.
Zacharia has served as laboratory director since July 2017, overseeing the lab’s extensive $2.5 billion research portfolio and staff of nearly 6, the press release said.
“An incredible leader, extraordinary collaborator, and powerhouse innovator, Thomas is leaving a profound impact on ORNL and the world,†said Randy Boyd, University of Tennessee system president and chairman of the UT-Battelle board of governors. UT-Battelle operates ORNL for the U.S. Department of Energy’s Office of Science.
In his tenure as lab director, Zacharia spearheaded significant growth in ORNL’s staff and portfolio, established new research initiatives, and guided the lab through the COVID-19 pandemic, the press release said.
Among milestones during Zacharia’s tenure as director, the press release said, the laboratory has:

Innovation has been required as federal cleanup crews work to deactivate and demolish the final portion of the former Radioisotope Development Laboratory at Oak Ridge National Laboratory.
The structure is known as the East Cell Bank, and it is on the U.S. Department of Energy’s list of high-risk excess contaminated facilities, said a press release from DOE Office of Environmental Management. The East Cell Bank is located in the heart of ORNL, near ongoing research missions.
Workers with cleanup contractor UCOR characterized the final cell to identify potential radiological and hazardous contamination, the press release said. They conducted the work in stages under a six-story protective structure erected to ensure nearby facilities and ongoing research missions at ORNL aren’t impacted by the cleanup.
The crews began by taking surveys and readings from an opening at the front of the structure, the release said. They used long-reach tools and a specialized radiation detector. The detector overlays a radiation-intensity color map on a picture of the environment and identifies gamma-ray emitting nuclides and their locations.
A former molecular geneticist at Oak Ridge National Laboratory will discuss regenerative medicine and a potential treatment for severe COVID-19 disease patients and those who struggle with “long haul” symptoms.
The talk by Cymbeline “Bem” Culiat—co-founder, president, and chief science officer of NellOne Therapeutics in Knoxville—will speak virtually to Friends of ORNL at noon Tuesday, February 8.
“While at ORNL, Culiat discovered the role of the NELL1 signaling protein in fostering the growth and maturation of musculoskeletal and cardiovascular tissues in mice and other mammals, including humans,” a press release said. “Her biotech company focuses on using her discovery to advance regenerative medicine, which involves replacing, engineering, or regenerating human or animal cells, tissues, or organs to promote healing and restore normal function. In contrast, traditional medicine typically provides treatment of symptoms rather than addressing root causes.”

The U.S. Department of Energy is upgrading a historic reactor in Oak Ridge to keep the facility safe until it can be demolished.
The reactor, the Molten Salt Reactor Experiment, is at Oak Ridge National Laboratory, and it was shut down nearly 50 years ago. At some point, the MSRE will be deactivated, and that will save about $5 million in annual operating costs, a press release said.
“We have the important responsibility of keeping it safe until major cleanup operations begin,†said Nathan Felosi, EM’s ORNL portfolio federal project director. “The latest round of projects is making sure that’s the case and achieving considerable cost savings to taxpayers.â€
