Oak Ridge National Laboratory has exercised an option to extend the American Centrifuge demonstration program into 2015, USEC announced Wednesday.

The announcement was included in a report on second quarter results, when the uranium enrichment company had a net loss of $28 million. USEC, which has operations in Oak Ridge, is undergoing a Chapter 11 bankruptcy and is turning over its gaseous diffusion plant in Paducah, Kentucky, to the U.S. Department of Energy.

Funding for the next-generation American Centrifuge activities was previously provided under a cooperative agreement with the U.S. Department of Energy. Under that cost-sharing agreement, DOE provided 80 percent of the funding, and USEC provided 20 percent for research, development, and demonstration work performed from June 1, 2012, through April 30, 2014, when the agreement expired.

On May 1, USEC signed a new agreement with UT-Battelle, which manages and operates ORNL for DOE. The agreement was called the American Centrifuge Technology Demonstration and Operations, or ACTDO, agreement, and it allows for continued cascade operations and the continuation of core American Centrifuge research and technology activities and the furnishing of related reports to ORNL, USEC said in its quarterly report.

On July 31, ORNL exercised its option to extend the period of performance for the ACTDO Agreement by an additional six months to March 31, 2015. The agreement also provides ORNL with one additional option to extend the agreement by six months to September 30, 2015. [Read more…]

Great Smoky Mountain Council of BSA launches STEM program

KNOXVILLE—The Great Smoky Mountain Council of the Boy Scouts of America has been granted permission by the National Executive Board to test a proof of concept called STEM Scouts (science, technology, engineering, and math), which for now, is only open to East Tennessee youth.

The program shows youth from elementary through high school how to apply STEM in their everyday lives and encourages them to develop those experiences into a future career. The program uses the Scout Oath and Scout Law as its cornerstone.

The STEM Scouts are split into three divisions: elementary school (third through fifth grade), middle school (sixth through eighth grade), and high school (ninth through 12th grade). A successful proof of concept could have nationwide implications as the BSA gets boys and girls excited about STEM.

“Specialized programs are not new to the Boy Scouts,” said Michael Ramsey, BSA marketing director. “In fact, the concept dates back as early as 1913 with the creation of Sea Scouting. We’re optimistic this will take off and have positive outcomes for youth everywhere.” [Read more…]

New training program prepares veterans, others to enter advanced manufacturing workforce

While 26-year-old wounded veteran Joseph Grabianowski has inspired Americans with his harrowing war story, someday he may be nationally known for building highly efficient exhaust systems for cars and trucks using 3D printing technology.

Grabianowski—pictured at left at the U.S. Department of Energy’s Manufacturing Demonstration Facility at Oak Ridge National Laboratory in front of a 3D printer holding a 3D-printed DOE seal and the plastic material from which it was made—is part of the Energy Department’s inaugural Energy Efficiency and Renewable Energy Advanced Manufacturing Internship. The pilot program is designed to provide accelerated, hands-on career training for veterans and next-generation engineers to prepare them to immediately enter the workforce of the growing advanced manufacturing industry.

Grabianowski stepped on an IED while deployed with his Army unit in Kandahar Province, Afghanistan, in May 2012. Damage from the blast required a rare, radical amputation of his lower body. He had long dreamed of being a U.S. Marshal but knew his path would now lead in a new direction. In a December 2013 interview with USA Today, Grabianowski said, “I still love my country…even though I can’t go be a marshal now, I can still go do something that would be a good service to my country.”

Barely two years later, his successful recovery is a testament to his personal will and determination. This self-proclaimed techie now envisions a career for himself in what he calls the “future of manufacturing,” which is additive manufacturing, also known as 3D printing. Through this pioneering program offered by the Energy Department’s Advanced Manufacturing Office, Oak Ridge Associated Universities, Pellissippi State Community College, and ORNL, Grabianowski is receiving the training needed to make his career goals a reality and prepare him to succeed in the additive manufacturing world.

“Where this industry is going to boom is right here in Oak Ridge,” Grabianowski said, “and the best engineers in the field are available through this program to teach me.” [Read more…]

KNOXVILLE—Sticker shock at the gas pump could soon be a thing of the past thanks to research being conducted by Oak Ridge National Laboratory and the University of Tennessee in Knoxville.

Among the key components in processing fuels, particularly bio-friendly ones, are the membranes that aid in the process of separating unwanted compositions such as water from the fuel or hydrocarbon from aqueous phase.

“We can help wallets and help profits at the same time,” said Michael Hu, a joint faculty member of ORNL and the College of Engineering’s Department of Chemical and Biomolecular Engineering. “If we can improve that separation process it will mean a reduction in cost to make, a reduction in cost to supply, and a reduction in cost to buy.”

The breakthrough technology being brought to life by the research team combines nanotextured pores with superhydrophobic or superhydrophillic—or, in plain terms, super water-repulsing and water-attracting—substances. [Read more…]

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.

Information from WYSH Radio

After an overwhelmingly negative reaction from employees, Oak Ridge National Laboratory has decided to drop a class that teaches how to minimize a southern accent. Officials said that some employees had requested the class, and the laboratory’s human resources department decided to open it up to all 4,000 employees.

To advertise the class, HR sent an email that implied there was something wrong with southern accents. Officials have since admitted that the email came across completely wrong and apologized for the miscommunication.

ORNL offers these accent classes frequently because English is a second language for many of its employees.
