The research of a UT professor working to create a battery that packs several thousand times more energy than batteries used today has received a boost from Oak Ridge Associated Universities (ORAU).
Eric Lukosi, an assistant professor in nuclear engineering, received a $10,000 Ralph E. Powe Junior Faculty Enhancement Award, including $5,000 from ORAU and $5,000 in matching funds from the UT Office of Research. The award is given to thirty young faculty members at ORAU member institutions with the goal of enriching their research and professional growth, spurring new funding opportunities.
ORAU provides innovative scientific and technical solutions for the U.S. Department of Energy (DOE) and other federal agencies to advance national priorities in science, health, education, and national security. A nonprofit corporation and federal contractor, ORAU manages the Oak Ridge Institute for Science and Education for the DOE.
"The Powe Award is very prestigious, and Eric's important research is very deserving," said Wayne Davis, dean of the College of Engineering. "This honor bodes well for his future success in sponsored research."
Lukosi's research focuses on the development of a long-lived, innovative nuclear battery termed a High Temperature Direct Energy Conversion (HiTDEC). The proposed battery operates by converting radioactive energy to electrical energy using a semiconducting diamond transducer.
"Current direct energy conversion nuclear batteries are very sensitive to radiation damage, thereby limiting the useful lifetime to a few days," said Lukosi. "The proposed nuclear battery aims to surpass this limitation by providing power generation for over a year. This can be especially useful for spacecraft and sensors."
The funds will be used for initial investigations into techniques that lessen radiation damage to the diamond transducer. The study is important to the success of the HiTDEC nuclear battery and will help define the achievable potential energy stored in the battery.
"ORAU is excited to support thirty exciting new ideas proposed by junior faculty from member institutions," said Arlene Garrison, ORAU vice president of University Partnerships, in a statement. "This funding enables creative exploration at a critical early career stage." (Posted 6/11/13)
Creative UT Nuclear Engineering Student Involved in Breakthrough Experiment
By G. Ivan Maldonado, Associate Professor, UT Department of Nuclear Engineering
On September 18, 2012, I was invited by one of my PhD students, David Dixon, currently working at Los Alamos National Laboratory (LANL), to be an observer at an experiment at the Device Assembly Facility (DAF) complex on the Nevada National Nuclear Security Site. A team of LANL, NASA, and NSTec engineers led by Dr. David Poston and David Dixon, among others, carried out a remarkable proof-of-concept test that employed the Flattop spherical benchmark assembly (Figure 1) as a source of heat to operate a Sterling engine and generate 24 watts of electricity. The thick natural uranium reflector can host small spherical cores of enriched fissile material to perform criticality experiments. A small team of –notably mostly young- engineers took advantage of an existing and vacant cylindrical hole in the assembly large enough to host a small diameter heat pipe that transferred the heat of fission from the core to power the Sterling engine, which in turn generated electricity. This unprecedented experiment was a great success in that it proved a relatively simple concept that could potentially be used to generate long-term electricity for deep space and long-term NASA applications.
It did not surprise me at all that David Dixon was involved in this rather unique experiment that involved quite a bit of engineering creativity, because I know him well. In fact, while he was pursuing his MS degree at UT, David helped me build a multi-core Beowulf cluster from scratch, which in and of itself was great but not overly remarkable, until one day I found out that he had installed a car radiator to help water cool the cluster cores "economically" because the AC in the room was inadequate (Figure 2). We ultimately decided against this bulky setup and opted for more compact heat pipe based (yes, heat pipe) CPU mounted cooling. However, it is hard to forget finding a radiator and jugs of antifreeze in my computer lab!
More recently, during the Fukushima nuclear tragedy in Japan, David was deployed as a backup to represent LANL in Washington DC as a nuclear engineering expert and advisor to the US government. Sometime during that period, questions and discussions led to exploring the feasibility of water jet cutting technology to help break through huge reinforced concrete structures. Under strong skepticism by experts, David led a team of engineers to look into this. See photos of: David setting up the water jet equipment (Figure 3), an enlarged view of the hole drilled through a large concrete block (Figure 4), and receiving an award of recognition for his Fukushima response service from the U.S. Secretary of Energy, Dr. Steven Chu (Figure 5).
I am certainly a fortunate and very proud professor to have run into such a creative individual like David Dixon as my graduate student. He's also the kind of person who never hesitates to give folks a hand to help fix your car or move across town. David is expected to complete his PhD in Nuclear Engineering in 2013, that is, if I can ever stop him from having so much fun! (Posted 11/29/12)

UT grad program testing radiation downtown by Gerald Witt
A white pickup with U.S. Government tags, a trailer of nuclear testing devices and a weather vane have diverted downtown Knoxville lately. But don't break out the hazmat suits. Matthew Beach, a grad student, is just monitoring equipment in the trailer measuring ambient nuclear energy bouncing around in the urban setting. This is not the focused, powerful stuff studied at Oak Ridge National Laboratory, but the natural nuclear energy that surrounds us — radiation from the sun, the Earth and elsewhere that we never notice. "You have invisible particles," Beach said in describing radiation. Devices in the trailer loaned from ORNL carry a voltage level, he said, "and particles change that current." The change in the current shows the amounts of radiation, Beach kindly described to a layperson. Jason Hayward, University of Tennessee assistant professor of nuclear engineering, is leading the research to determine a baseline that will show fluctuations in radiation. "We're just mapping," Hayward said.
On Thursday police closed Wall Avenue for the afternoon so Beach could park the truck and run generator-powering computers and other technology in the trailer. The mapping, he said, will continue downtown throughout next week. "It's kind of boring," Beach said, jotting notes.

UT, ORNL Lead National Team to Study Materials Performance in Nuclear Fusion Reactors
KNOXVILLE — Power from nuclear fusion reactors has the promise to be safe, sustainable and limitless. But science has not been able to bring fusion energy to the commercial energy market. This is partly because the operating limits of the reactor materials are not known. A team of researchers at the University of Tennessee, Knoxville, and Oak Ridge National Laboratory, in collaboration with seven other institutions, is trying to change that. Led by Brian Wirth, UT-ORNL Governor's Chair for Computational Nuclear Engineering, the Scientific Discovery through Advanced Computing (SciDAC) project will receive $2.3 million from the Department of Energy for the first year with plans for a total of $11.5 million over five years. ORNL and UT will receive $850,000 for the first year with plans for a total of $4.1 million over five years. Nuclear fusion promises an almost limitless supply of clean and safe energy. Unlike the nuclear fission reactors used today, it doesn't come with the challenge of managing used nuclear fuel containing very long-lived radioactivity. This is because the process to create the energy is different. In nuclear fission, an atom is split into two smaller atoms which remain radioactive for hundreds to many thousands of years. In fusion, two or more smaller atoms are fused into a larger atom that is not radioactive. "However, the fusion process currently pursued unleashes a very high-energy neutron that is believed to produce more damage to reactor materials than in fission," Wirth said. "Now is the right time to examine this impact of fusion reactions on materials as we determine whether we can really make fusion work as a practical energy source." The researchers will examine how the surfaces of materials which comprise the reactor respond when being bombarded by energetic neutrons and ions. Using high-performance computers such as ORNL's Jaguar and UT's Kraken, the researchers will try to accurately predict materials' performance and evaluate materials systems and component design for the fusion reactor environment. The team will then be positioned to use their computational tools to evaluate new materials and component designs to enable fusion energy. "A fusion reactor works by introducing plasma — a hot, electrically charged gas that serves as the reactor fuel — into a vacuum vessel," Wirth said. "The plasma is then confined using electric and magnetic fields into a central, vacuum region." The problem, he said, is that ions from the plasma escape and bombard the material surfaces, in addition to the high-energy neutrons. This combination causes significant damage and changes the properties of the reactor materials. "It's likely materials do not exist today that could be used to build a reactor that would contain the plasma," Wirth said. The material property changes are driven by many processes that occur in less than a nanosecond. Yet, it is the cumulative interaction of such processes over much longer times that determine the precise value of these changes. Wirth and his team aim to develop models which stretch this interaction over the period of many decades to evaluate their long-term effects. "We are trying to identify and model numerous microscale defect and impurity interaction processes that occur over rapid time scales which can span less than a nanosecond," Wirth said. "And then we are trying to integrate these into a model that can predict the material response over the years and decades for which a plasma reactor needs to operate." Wirth notes that making these goals more challenging is the fact that no current experimental facilities exist that accurately represent the environment these materials are expected to face. "Our research will address one critically important aspect toward getting to fusion energy," Wirth said. "I'm optimistic about the potential for fusion energy, but realistic in understanding how difficult it will be to realize." The Department of Energy's Office of Fusion Energy Sciences and Office of Advanced Scientific Computing Research are jointly funding this SciDAC project. Collaborating institutions include Argonne National Laboratory; Los Alamos National Laboratory; Pacific Northwest National Laboratory; University of California, San Diego; University of Illinois at Urbana-Champaign; University of Massachusetts, Amherst; and General Atomics.
