Alexander Inn Groundbreaking

Local, state, and federal officials join volunteers and nonprofit and business executives for a groundbreaking ceremony at the historic Alexander Inn in November.

Gov. Bill Haslam is supporting a nomination for a national historic preservation award for a project converting the Alexander Inn in Oak Ridge into an assisted living center.

Knox Heritage and East Tennessee Preservation Alliance have nominated the hotel for the 2014 The National Trust/Advisory Council on Historic Preservation Award for Federal Partnerships in Historic Preservation.

In a Feb. 25 letter, Haslam said he supports the nomination. The letter was sent to Stephanie Meeks at the National Trust for Historic Preservation in Washington, D.C.

The Alexander Inn was built during World War II, when Oak Ridge raced to help build the world’s first atomic weapons as part of the top-secret Manhattan Project. Guests who once stayed at the two-story hotel included Gen. Leslie Groves, Secretary of War Henry Stimson, and physicists J. Robert Oppenheimer and Enrico Fermi. [Read more…]

GAO denies third protest of $22 billion contract to manage Y-12, Pantex

Federal officials have denied the third protest by one of the two teams that unsuccessfully bid on a $22 billion contract to manage the Y-12 National Security Complex in Oak Ridge, pictured above, and Pantex Plant near Amarillo, Texas.

Note: This story was updated at 6:45 p.m.

Federal officials have denied the third protest by one of the two teams that unsuccessfully bid on a $22 billion contract to manage the Y-12 National Security Complex in Oak Ridge and Pantex Plant near Amarillo, Texas.

In the protest, Nuclear Production Partners LLC of Lynchburg, Va., had challenged a November decision by the National Nuclear Security Administration to reaffirm its earlier decision, announced in January 2013, to award the consolidated contract to Consolidated Nuclear Security LLC of Reston, Va.

On Thursday, the U.S. Government Accountability Office announced that it had denied the third protest. It’s the final GAO protest, but the case could be appealed to the U.S. Court of Federal Claims in Washington, D.C.

Statistically, that’s not likely; the GAO hears 2,500 protests per year, and the court has about 84. But there is a large amount of money at stake with this contract.

The GAO had upheld one part of an earlier NP2 protest and denied or dismissed three elements of a second. [Read more…]

KNOXVILLE—Some of the best and brightest undergraduate students from around the United States gathered at the University of Tennessee in Knoxville recently for the chance to meet top experts in the field of nuclear engineering, including representatives from federal sites in Oak Ridge.

“This area really is the birthplace of a lot of activities related to nuclear engineering,” said Wesley Hines, head of UT’s Department of Nuclear Engineering, which sponsors the annual event. “Some of these kids don’t realize all of the nuclear-related opportunities that exist here until they do this program. What we hope to achieve is to let people see all that is possible, all that is already in place when they come here.”

The sessions gave prospective graduate students a chance to mingle with some of the biggest names in nuclear research and energy, including from the Y-12 National Security Complex, Oak Ridge National Laboratory, the UCOR facilities at the East Tennessee Technology Park, and Tennessee Valley Authority, as well as with UT faculty and students.  [Read more…]

ORHS team will compete in National Science Bowl

High school students from across Tennessee competed on Saturday, Feb. 22, at Pellissippi State Community College’s Blount County Campus, in the U.S. Department of Energy’s Tennessee Science Bowl competition. Fifty-five high school teams comprised of four students, and one alternate student, answered challenging mathematical problems and tested their knowledge in broad disciplines including chemistry, biology, earth and space science, physics, and energy.

Training for months after school, the student competitors committed hours of study to expanding and honing their mathematics and science knowledge and competition skills. And, all their work showed. Many of the competition rounds came down to the last nail-biting seconds before a winner emerged. However, in the end, Oak Ridge High’s Team 1 edged out their competitors, placing first.

Oak Ridge High School received a $1,000 cash prize, a first-place trophy, and an all-expenses-paid trip to the DOE National Science Bowl in Washington, D.C., from April 24-28, when they will compete against other winning teams from around the nation. [Read more…]

KNOXVILLE—With the installation of LED fixtures, the Thompson-Boling Arena at the University of Tennessee in Knoxville is one of the first in the world to feature lights that are smaller, brighter, and up to 85 percent more efficient than conventional arena metal halide lights.

The technology—developed and manufactured by Oak Ridge-based LED North America at the Tech 20/20 incubator facility in Oak Ridge, incorporating an Oak Ridge National Laboratory technology, and installed by Knoxville-based Bandit Lites—is being “premiered” at the state’s research university inside the largest on-campus single-sport arena in the country.

The light-emitting diode fixtures use an ORNL-developed lightweight graphite foam that cools the LED, making them more efficient and reliable. This enables 90 400-watt LED fixtures to bathe the arena’s floor with 200 foot-candles per square foot, compared to the 130 foot-candles produced by the arena’s existing 110 1,100-watt fixtures.

LED North America’s SuperSport luminaires have the potential to revolutionize sports and entertainment venues worldwide. UT officials are looking forward to participating in this effort and to seeing the results—and the savings. [Read more…]

Using a new microscopy method, researchers at Oak Ridge National Laboratory can image and measure electrochemical processes in batteries in real time and at nanoscale resolution.

Scientists at ORNL used a miniature electrochemical liquid cell that is placed in a transmission electron microscope to study an enigmatic phenomenon in lithium-ion batteries called the solid electrolyte interphase, or SEI, as described in a study published in Chemical Communications.

The SEI is a nanometer-scale film that forms on a battery’s negative electrode due to electrolyte decomposition. Scientists agree that the SEI’s formation and stability play key roles in controlling battery functionality. But after three decades of research in the battery field, details of the SEI’s dynamics, structure, and chemistry during electrochemical cycling are still debated, stemming from inherent difficulties in studying battery electrode materials in their native liquid environment.

“We’ve used this novel in situ method to understand the dynamics of how this layer forms and evolves during battery operation,” said Raymond Unocic, ORNL research and development staff scientist. [Read more…]
