Federal laboratories in Oak Ridge and Idaho, along with a nuclear research center in Belgium, will make their research reactors, labs, and education and training facilities available to scientists from other countries for training, research, and development, officials announced at the IAEA General Conference in Austria on Monday.

The IAEA is the International Atomic Energy Agency.

The facilities that will make their reactors available are the U.S. Department of Energy’s Oak Ridge National Laboratory and Idaho National Laboratory, and the Belgian Nuclear Research Centre SCK*CEN, the IAEA said.

The institutions received designations as IAEA International Centres based on Research Reactor, or ICERR, the IAEA said.

The reactors include the High Flux Isotope Reactor at ORNL, the Advance Test Reactor at Idaho National Laboratory, and the Belgian Reactor 2. [Read more…]

In a first-of-a-kind experiment, researchers used neutrons to investigate the performance of a new aluminum alloy in a gasoline-powered engine—while the engine was running.

A team from the U.S. Department of Energy’s Oak Ridge National Laboratory worked with industry partners to perform the test, which looked at whether a high-performance alloy that is promising for automotive applications held up under the heat and stress of an internal combustion engine.

Researchers used neutrons to probe a running engine at ORNL’s Spallation Neutron Source, giving them the opportunity to test an aluminum-cerium alloy under operating conditions.

The feat was a first for the Spallation Neutron Source, said Ke An, lead instrument scientist for the facility’s VULCAN instrument.

“This was the first time an internal combustion engine has been run on our diffractometer, and, as far as we know, on any other,” he said. [Read more…]

The small modular nuclear reactors being evaluated for the Clinch River Site in west Oak Ridge could provide an emissions-free fuel source, but it could be a decade or so before they start operating. And that’s assuming all goes according to plan, officials said Tuesday.

The Tennessee Valley Authority is evaluating the possibility of building the small modular reactors, or SMRs, at the 1,200-acre Clinch River Site. To help prepare for the project, TVA plans to apply for what is known as an early site permit, or ESP, for the Oak Ridge project from the U.S. Nuclear Regulatory Commission by May 12.

The NRC had two public meetings at Oak Ridge Associated Universities on Tuesday to discuss the safety and environmental review process related to the TVA permit application.

The early site permit application will allow the NRC to evaluate site safety, the environment, and emergency preparedness for future SMRs at the Clinch River Site. That site is in west Oak Ridge just north of the Clinch River and Interstate 40, south of Heritage Center (the former K-25 site), and between Highway 95 and Highway 58 in a bend of the Clinch River.

The review of TVA’s application for an early site permit could take about three years, and maybe longer if any groups raise legal challenges, said Scott Burnell, NRC public affairs officer. [Read more…]

What if charging your plug-in electric vehicle was as easy as parking it? No need for cords or cards. Just as Wi-Fi has freed consumers of wires when accessing the Internet, wireless charging technology may soon be as widespread, thanks to research supported by the U.S. Department of Energy.

With support from the Vehicle Technologies Office, Oak Ridge National Laboratory and Hyundai America Technical Center Inc. have been working since 2012 to demonstrate wireless charging on a variety of vehicles. ORNL is working with a mix of Toyota vehicles, including models of the all-electric RAV 4, plug-in hybrid electric Prius, and all-electric Scion iQ, while Hyundai America Technical Center Inc. is testing its technology on five all-electric Kia Souls.

The technology behind wireless charging creates a connection between a transmitting pad on the ground (such as in a garage) and a receiving pad integrated on the bottom of the vehicle. In the projects ORNL is leading, the transmitting pad is connected to a 240-volt outlet and generates a magnetic field of a certain frequency. When the coil in the receiving pad is tuned to oscillate at the same frequency, the magnetic field will generate a current in the receiving coil, charging the vehicle’s battery. [Read more…]

Researchers at the U.S. Department of Energy’s Oak Ridge National Laboratory will support two new DOE-funded projects to explore, develop, and demonstrate advanced nuclear reactor technologies.

The projects announced January 15 will allow industry-led teams with participants from universities and national laboratories to further nuclear energy technology, and will enable companies to further develop their advanced reactor designs with potential for demonstration in the mid-2030s. Initially, DOE’s investment will be $6 million for each project and both companies will provide cost-share. The possible multi-year cost-share value for this research is up to $80 million.

A project led by Southern Company Services, a subsidiary of Southern Company, focuses on molten chloride fast reactors, or MCFRs. The effort includes ORNL, TerraPower, the Electric Power Research Institute, and Vanderbilt University. [Read more…]

Plutonium-238 produced at ORNL helps restores ability to power NASA space missions

With the production of 50 grams of plutonium-238, researchers at the U.S. Department of Energy’s Oak Ridge National Laboratory have restored a U.S. capability dormant for nearly 30 years and set the course to provide power for NASA and other missions.

Plutonium-238 produces heat as it decays, and it can be used in systems that power spacecraft instruments. The new sample, which is in the same oxide powder form used to manufacture heat sources for power systems, represents the first end-to-end demonstration of a plutonium-238 production capability in the United States since the Savannah River Plant in South Carolina ceased production of the material in the late 1980s.

Researchers will analyze the sample for chemical purity and plutonium-238 content, then verify production efficiency models and determine whether adjustments need to be made before scaling up the process.

“Once we automate and scale up the process, the nation will have a long-range capability to produce radioisotope power systems such as those used by NASA for deep space exploration,” said Bob Wham, who leads the project for the lab’s Nuclear Security and Isotope Technology Division. [Read more…]

NASA’s New Horizons spacecraft just accomplished one of the most exciting feats in the history of space exploration. After a 9.5-year, 3-billion-mile journey, the mission’s historic flyby of Pluto has provided us with our first-ever closeup views of the frozen world at the edge of the solar system. It’s a remarkable achievement, one that wouldn’t have been possible without careful planning, ingenuity—and a little help from the U.S. Department of Energy.

In 2006, when NASA engineers were designing New Horizons, they knew that it would need a long-lasting, compact and incredibly reliable power source to survive the cold, dark reaches of outer space.

Solar power was out of the question. The spacecraft’s itinerary would take it billions of miles from the center of the solar system into the realm of Pluto and the Kuiper Belt. That far out, the Sun shines with just a tiny fraction of the intensity we see here on Earth—scarcely brighter than the stars in the night sky. Other options like batteries or fuel cells wouldn’t last long enough. [Read more…]

NNSA marks 10th anniversary of Global Threat Reduction Initiative

WASHINGTON, D.C.—The National Nuclear Security Administration on Thursday marked the 10th anniversary of the Global Threat Reduction Initiative, GTRI. Since the Sept. 11 attacks, reducing the threat of terrorist acquisition of nuclear or radiological material has been a core mission of NNSA, and it is a mission that will continue into the future.

“The Global Threat Reduction Initiative’s history demonstrates how seriously we take this mission and our commitment to fulfilling President Obama’s nuclear security agenda,” said U.S. Department of Energy Under Secretary for Nuclear Security and NNSA Administrator Frank G. Klotz. “However, the threat to national and global security from state or terrorist acquisition of nuclear and radiological materials is far from gone, and our focus now is on addressing the substantial threats that remain.”

GTRI, an NNSA nuclear nonproliferation program, works with partners around the world to reduce and consolidate global stockpiles of highly enriched uranium, or HEU, and plutonium, and to secure dangerous radiological sources both at home and abroad. GTRI and its predecessor programs have removed and secured more than enough material for 980 nuclear weapons and tens of thousands of radiological dirty bombs by converting HEU research reactors and isotope production facilities to the use of low enriched uranium, or LEU; removing or confirming disposition of HEU and plutonium; and securing nuclear and radiological sites around the world.

WASHINGTON, D.C.—The National Nuclear Security Administration recently successfully recovered a disused, high-activity cesium-137 source from Massachusetts General Hospital in downtown Boston and transported it for permanent disposition. Formerly used as a research irradiator for medical studies, the device contained cesium-137, which could be used in a dirty bomb. The removal was part of NNSA’s global campaign to prevent terrorists from acquiring nuclear and radiological material.

“This operation is a key part of the NNSA’s broad strategy to strengthen both U.S. and global security by keeping dangerous nuclear and radiological material safe and secure,” said NNSA Deputy Administrator for Defense Nuclear Nonproliferation Anne Harrington. “Today’s announcement is a good example of how NNSA utilizes its unique expertise and assets at the national laboratories to partner with local communities and other agencies to make our cities and those around the world safer and more secure.” [Read more…]
