A car and house built using large-scale 3D printers at Oak Ridge National Laboratory can provide power to each other, and they’re part of a project designed to answer “what if” questions that could lead to innovations in building and car construction and energy use, storage, and consumption, researchers and officials said Wednesday.

The 210-square-foot house—it’s a solar-powered building—and the printed utility vehicle—officials affectionately call it a PUV—were printed at ORNL’s Manufacturing Demonstration Facility on Hardin Valley Road.

They were unveiled at ORNL on Wednesday during the lab’s first-ever Industry Day. The building and PUV are part of a project called the Additive Manufacturing Integrated Energy, or AMIE, demonstration.

Additive manufacturing is the process used to build something one layer at a time. One of the most well-known examples is the Shelby Cobra car 3-D printed on a large-scale polymer printer at the MDF. President Barack Obama and Vice President Joe Biden admired that vehicle—and joked about taking it for a spin—during a trip to East Tennessee in January. [Read more…]

Alvin Weinberg Poster

The world premiere of a new film on the life of former Oak Ridge National Laboratory Director Alvin Weinberg will be held on Thursday, April 23, at the American Museum of Science and Energy in Oak Ridge. The film was written and directed by award-winning documentary filmmaker and Oak Ridge resident Keith McDaniel.

Although McDaniel has written and directed more than a dozen documentary films, he is generally best known for his films “Secret City: The Oak Ridge Story” and “The Clinton 12.”

According to McDaniel, the biographical documentary entitled “Alvin Weinberg” explores the life of the internationally renowned nuclear scientist.

“I didn’t know Dr. Weinberg very well although I did interview him a couple of years prior to his death,” McDaniel said. “His was a fascinating life. In making this film, I wanted to not only tell stories of his professional achievements but I also wanted to show what Dr. Weinberg was like as a person.” [Read more…]

A new group of state and federal workers that was announced Tuesday could discuss contentious waste-related issues that include concerns over shipping low-level radioactive waste from a World War II-era building in Oak Ridge to a federal landfill in Nevada.

The new group, which will include senior-level state and federal employees, was announced in a six-page agreement, a memorandum of understanding signed last week by Energy Secretary Ernest Moniz and Nevada Governor Brian Sandoval.

The talks started more than a year ago, after Sandoval sent a letter to Moniz expressing concerns over the proposed disposal of the radioactive waste at the Nevada National Security Site, a former nuclear weapons proving ground about 65 miles northwest of Las Vegas.

The waste contains radioisotopes of uranium from the Consolidated Edison Uranium Solidification Project. It originated from a 1960s research and development test of thorium and uranium reactor fuel in New York. It is stored at Oak Ridge National Laboratory in Building 3019—the oldest continuously operating nuclear facility in the Department of Energy complex—in 403 ceramic-like uranium oxide monoliths. Each of the monoliths is bonded to the inside of a steel canister about 3.5 inches in diameter and about two feet long. [Read more…]

For the fourth consecutive time, Tianhe-2, a supercomputer developed by China’s National University of Defense Technology, has retained its position as the world’s number one system. Meanwhile, Titan at Oak Ridge National Laboratory, which was the top supercomputer in November 2012, remains number two.

Tianhe-2 is capable of performing at 33.86 petaflops, or 33.86 quadrillions of calculations per second, on a benchmark test known as Linpack.

The rankings are from the 44th edition of the twice-yearly TOP500 list of the world’s most powerful supercomputers, which was announced Monday in Mannheim, Germany; Berkeley, California; and Knoxville. Tianhe-2 has been in the top spot four consecutive times, and Titan has been number two each time. [Read more…]

The High Flux Isotope Reactor, or HFIR, now in its 48th year of providing neutrons for research and isotope production at Oak Ridge National Laboratory, has been designated a Nuclear Historic Landmark by the American Nuclear Society.

“This designation from the ANS recognizes HFIR’s role in the history of the nuclear age, but it also speaks to the excellence of its design and operation,” ORNL Director Thom Mason said. “HFIR remains one of the world’s most capable reactor-based neutron science, radioisotope production, and materials irradiation facilities, and we expect that to continue for many years.”

The designation was proposed by the ANS honors and awards committee and approved on initial ballot by the board of directors.

“The ANS Nuclear Historic Landmark signifies that a nuclear facility has played an important role in nuclear science and engineering,” ANS President Michaele C. Brady Raap said. “HFIR, with its preeminent role in isotope production and neutron science, certainly meets that criteria.”

The reactor was conceived in the late 1950s as a production reactor to meet anticipated demand for transuranic isotopes (“heavy” elements such as plutonium and curium). HFIR today is a U.S. Department of Energy Office of Science User Facility and one of the world’s sole sources of the radioisotope californium-252, used in industry and medicine. ORNL is a DOE lab.

Ramamoorthy Ramesh

Five Oak Ridge National Laboratory physicists, including Deputy for Science and Technology Ramamoorthy Ramesh, have been named by Thomson Reuters as some of the best and brightest of our time.

The list consists of scientists whose work has been most frequently cited by peers as identified by Thomson Reuters platforms. Citation data was divided into two categories—2002-2012 and 2012-2013—with the latter labeled “hot papers,” ranking in the top 0.1 percent by citations in their field. Seventeen researchers earned this distinction while some 3,200 were included in the second section of the ranking with citations ranking in the top 1 percent for their field and year of publication.

Ramesh, who was actually listed in two categories—physics and materials science—was named to his position at ORNL in June 2013 after serving as the Plato Malozemoff Chair Professor of Materials Science and Engineering and Physics at the University of California, Berkeley, with a joint appointment as a faculty senior scientist at Lawrence Berkeley National Laboratory. He holds a doctorate in materials science from the University of California, Berkeley, and was elected to the National Academy of Engineering in 2011 in recognition of his contributions to the science and technology of functional complex oxide materials.

The Spallation Neutron Source at Oak Ridge National Laboratory operated steadily at its full design power of 1.4 megawatts for researchers for the first time on June 26.

“We’re producing neutrons now at this intensity for user experiments,” spokesman Bill Cabage said in a telephone interview last week.

The $1.4 billion SNS is a U.S. Department of Energy Office of Science user facility built on a ridge top at ORNL. It uses a linear proton accelerator and mercury target to provide the most intense pulsed neutron beams in the world for scientific research and industrial development. The proton beam hits the mercury target, knocking off neutrons from liquid mercury atoms. The neutrons, which are used to study materials from superconductors to biological systems, are then channeled down 16 instrument beam lines, where neutron spectrometers produce data revealing the structures and dynamics of molecules and atoms.

The SNS has been used for experiments since it started producing neutrons in April 2006, but at lower power. Researchers wanted to eventually get to full power, even if that had to be done gradually during the past eight years.

“They didn’t want to have a lot of disruption playing with it,” Cabage said. “They wanted to keep it reliable for users.” [Read more…]

Tractor-trailer prototype uses probe developed by ORNL for better gas mileage, cleaner exhaust

It’s a sleek, aerodynamic freight-hauling machine. With its wide tires, rounded edges, and body parts that hug the ground, this million-dollar prototype looks like it could be at home on a race track.

It’s already achieved celebrity status, serving as the backdrop for President Barack Obama during a February speech on greenhouse gas emissions and fuel efficiency standards.

But the SuperTruck is more likely to end up hauling meat and potatoes from Boise to Boston.

SuperTruck at ORNL

The fuel-efficient SuperTruck, the result of a four-year collaboration between the trucking industry and the federal government, made a pit stop at Oak Ridge National Laboratory on Tuesday.

Still, researchers have reason to celebrate. On Tuesday, they said the high-tech tractor-trailer has increased fuel efficiency by 75 percent. Fully loaded, the SuperTruck can drive 10.7 miles on a gallon of gas. That compares to an industry average of 5.8 to 6.5 miles per gallon.

“This is a really big deal,” said Claus Daniel, deputy director of sustainable transportation projects at Oak Ridge National Laboratory, where the SuperTruck made a pit stop on Tuesday.

It’s the result of a collaboration between the trucking industry and the U.S. Department of Energy. It’s not clear how soon the new technologies tested in the Cummins/Peterbilt tractor-trailer, which was built in Denton, Texas, will show up on the nation’s highways. [Read more…]

The U.S. Department of Energy and UT-Battelle could negotiate a five-year contract extension at Oak Ridge National Laboratory, officials said Thursday.

The current contract ends in March 2015. If granted, the extension would allow UT-Battelle to manage the lab though 2020. UT-Battelle is a nonprofit partnership between the University of Tennessee and Battelle Memorial Institute.

U.S. Rep. Chuck Fleischmann, a Tennessee Republican, announced the potential contract extension during a special holiday meeting of the East Tennessee Economic Council on Thursday. ETEC had asked DOE to not rebid the contract—but extend it instead, Fleischmann said.

The congressman said the negotiations over a possible extension were based on a “job well-done” at the premier lab. [Read more…]
