President Joe Biden will appoint Merlin Theodore of Oak Ridge National Laboratory to the National Science Board, the White House said in an announcement last week.

Theodore is the first full-time researcher from a national laboratory to serve on the National Science Board, the governing board for the National Science Foundation, according to ORNL.

“Merlin’s appointment to the National Science Board is indicative of her accomplishments as a researcher, her contributions to national missions, and her advocacy for women and minorities in science,” said interim ORNL Director Jeff Smith.

Theodore is one of eight new board members. The National Science Board is made up of 25 members appointed by the president, and they serve six-year terms.

The National Science Board pursues the goals and function of the NSF, including the duty to “recommend and encourage the pursuit of national policies for the promotion of research and education in science and engineering,” according to the White House news release.

A team at ITER, an international experimental fusion reactor in southern France, prepare on Feb. 10, 2022, to move one of six modules for a central solenoid, a powerful superconducting magnet being built by General Atomics in California under the management of Oak Ridge National Laboratory.

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.

The U.S. Department of Energy’s Oak Ridge National Laboratory appointed Peter Thornton as director of its Climate Change Science Institute, or CCSI, effective November 1.

“CCSI was launched at ORNL in 2009, bringing together the lab’s multidisciplinary expertise and big science capabilities to predict the future of the planet’s climate and to evaluate potential mitigation solutions at the intersection of climate, clean energy, national security, and environmental justice,” a press release said. “ORNL’s modeling work informs solutions to meet the nation’s climate goals of a 40% reduction in global greenhouse gas emissions by 2030 and net-zero GHG emissions by 2050.”

“I am very pleased that Peter will help develop and guide new local, regional, and national activities within CCSI,” said Stan Wullschleger, associate laboratory director for Biological and Environmental Systems Science. “Peter’s extensive expertise will ensure that our Earth system models provide the best projections of our changing planet and potential resilience strategies for our citizens, industry and society.”

ORNL to receive $497 million in Inflation Reduction Act funding 

Posted at
By Leave a Comment

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

Demolition began in September 2022 on the Bulk Shielding Reactor at the Oak Ridge National Laboratory, and it was completed in November. It was the first teardown of a former reactor at the site. (Photo by U.S. Department of Energy Office of Environmental Management)

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.
