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.
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.”
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.

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:

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.
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 three-and-a-half-hour tours allow visitors to see all three DOE sites on the Oak Ridge Reservation, including Oak Ridge National Laboratory (ORNL), Y-12 National Security Complex, and East Tennessee Technology Park.

The meeting is scheduled to start at 6 p.m. Tuesday, July 19, in the Oak Ridge Municipal Building Courtroom.
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:

The Oak Ridge Municipal Planning Commission on Thursday will consider rezoning 110 acres at Horizon Center for a nuclear fuel fabrication company.
The property (Lot 6a) has been purchased from the Oak Ridge Industrial Development Board by TRISO-X LLC, a nuclear fuel company that announced expansion plans in Oak Ridge in April 2022, the city staff said. The company said it hopes to bring hundreds of highly skilled, high-paying jobs to the Oak Ridge area and further “Oak Ridge’s well-earned reputation as the center of U.S. nuclear innovation and excellence.”
