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.

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.

The Y-12 National Security Complex flipped the switch on a new era as crews finalized the process of moving the entire site’s electrical supply to the new Pine Ridge substation.
In June, the Building 9204-02 (Beta 2) and Building 9201-01 (Alpha 1) electrical feeds were disconnected from the Elza-1 substation, marking the final load transition to Pine Ridge.
The new substation was built as one of seven Uranium Processing Facility Project subprojects. Designed and built by the Tennessee Valley Authority, Pine Ridge substation construction began in 2017 and was completed in 2020 at a cost of $60 million. The project team received the U.S. Department of Energy Secretary’s Project Management Achievement Award for finishing $13 million under budget and six months ahead of schedule. It is a 70-MVA (mega volt amp) facility and includes:
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.

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.
